Medicare Advantage
Quick Reference Guide

Medicare Advantage (also called Part C) is a way to get your Medicare benefits through a private insurance company instead of directly through the government. The plan still has to cover everything Original Medicare covers, but it's run by a company like Aetna, Humana, or UnitedHealthcare.

Medicare Advantage is an alternative to Original Medicare, offered by private insurance companies that are approved by and under contract with Medicare. These plans must cover everything Original Medicare (Part A and Part B) covers, with the exception of hospice care, which remains billed under Original Medicare even for MA enrollees. Most Medicare Advantage plans also bundle in Part D prescription drug coverage and many include extra benefits — dental, vision, hearing, and sometimes fitness or transportation benefits — that Original Medicare doesn't offer at all.

Sort of — you still legally have Medicare, but instead of the government paying your claims directly, a private company is paid to manage your benefits for you. Think of it like Medicare hiring a contractor to run your coverage.

Yes and no. Enrolling in Medicare Advantage does not mean you give up Medicare — you remain entitled to Medicare and must keep paying your Part B premium. What changes is who administers your benefits day to day. CMS pays the private insurance company a set amount per enrollee, and that company takes on the responsibility of covering your Part A and Part B services (and usually Part D), in exchange for following Medicare's rules on required coverage.

Medicare pays the insurance company a fixed amount for each person enrolled, regardless of how much care that person actually uses that year. The company then has to manage your care within that budget — which is part of why they use provider networks and rules like prior authorization.

CMS pays Medicare Advantage carriers a capitated rate — a fixed monthly amount per enrollee, adjusted for that person's risk profile (age, health conditions, etc.) — rather than reimbursing for each individual service like it does under Original Medicare's fee-for-service model. This funding structure is the underlying reason Medicare Advantage plans use networks, referrals, and prior authorization: the carrier is financially responsible for managing the member's overall cost of care within that fixed payment.

You'll still have Original Medicare, but for day-to-day use you'll show your Medicare Advantage plan's ID card at the doctor's office and pharmacy, not your red, white, and blue Medicare card.

Once enrolled in a Medicare Advantage plan, members generally use their plan-issued ID card for medical and prescription services rather than their original Medicare card. The original Medicare card should still be kept in a safe place, since it confirms underlying Medicare entitlement, but it is not the card presented for routine care while enrolled in an MA plan.

Not at all — even within the same company, plans can look completely different from one county to the next. Two people living a few miles apart, in different counties, might be offered totally different plan options.

Medicare Advantage plan availability, benefits, premiums, networks, and extra perks are determined at the county level and can vary significantly even between neighboring counties in the same state. Carriers design and price plans based on local market competition, provider contracting, and county-level CMS payment rates, which is why a client's specific ZIP code is always the starting point for any real plan comparison.

Basically, if you have both Medicare Part A and Part B, and you live in the plan's service area, you can enroll. There's one big exception: people with End-Stage Renal Disease used to be excluded, but that's changed in recent years.

To enroll in a Medicare Advantage plan, a person generally must be entitled to Part A and enrolled in Part B, and must live within the plan's specific service area. As of 2021, individuals with End-Stage Renal Disease (ESRD) gained the ability to enroll in Medicare Advantage plans, a change made by the 21st Century Cures Act — previously, ESRD patients were largely restricted to Original Medicare.

The same 7-month window you have for signing up for Medicare in general — 3 months before your 65th birthday month, your birthday month, and 3 months after — also lets you choose a Medicare Advantage plan right out of the gate.

During the Initial Enrollment Period (IEP) — the 7-month window surrounding a person's 65th birthday — a newly eligible beneficiary may enroll directly into a Medicare Advantage plan as their first form of Medicare coverage, rather than starting with Original Medicare and switching later. The same IEP timing rules apply to those becoming eligible for Medicare due to disability.

Every year from October 15 to December 7, anyone with Medicare can switch, join, or drop a Medicare Advantage or Part D plan for the upcoming year. Whatever you pick takes effect January 1.

The Annual Enrollment Period (AEP) runs October 15 through December 7 each year. During AEP, beneficiaries can switch from Original Medicare to a Medicare Advantage plan, switch from Medicare Advantage back to Original Medicare, switch from one Medicare Advantage plan to another, or join, switch, or drop a standalone Part D plan. All AEP elections take effect on January 1 of the following year.

If you're already in a Medicare Advantage plan and realize early in the year that it isn't working out, you get a do-over window from January 1 through March 31 to switch to a different Medicare Advantage plan or go back to Original Medicare.

The Medicare Advantage Open Enrollment Period (MA OEP) runs January 1 through March 31 each year and is available only to people already enrolled in a Medicare Advantage plan as of January 1. During this window, they may make one election: switching to a different Medicare Advantage plan, or dropping Medicare Advantage entirely to return to Original Medicare (and, if doing so, also enrolling in a standalone Part D plan). MA OEP cannot be used to switch between standalone Part D plans while staying on Original Medicare, and it is not available to people enrolled in Original Medicare who want to join Medicare Advantage for the first time.

Nothing bad — if you don't pick a Medicare Advantage plan, you simply stay on Original Medicare. There's no penalty or default enrollment into Part C; it's always an opt-in choice.

Enrollment in Medicare Advantage is always voluntary and requires an affirmative election by the beneficiary — there is no automatic or default enrollment into a Medicare Advantage plan. A person who does not actively choose a Medicare Advantage plan simply remains on Original Medicare (Parts A and B), and can separately decide whether to add a standalone Part D plan and/or a Medicare Supplement policy.

An HMO is the most network-restrictive option — you generally pick a primary care doctor, get referrals to see specialists, and stay inside the plan's network except for emergencies. In exchange, HMOs tend to have lower premiums and cost-sharing.

Health Maintenance Organization (HMO) Medicare Advantage plans require members to use a defined network of doctors and hospitals for non-emergency care, and typically require a referral from a primary care provider before seeing a specialist. Going outside the network for non-emergency care is generally not covered at all (except in specific HMO-POS variants, which allow limited out-of-network use at higher cost). HMOs tend to offer the lowest premiums and cost-sharing among MA plan types, in exchange for the tightest network restrictions.

A PPO gives you more freedom — you can see specialists without a referral, and you can go out-of-network if you're willing to pay more for it. The tradeoff is usually a higher premium or higher cost-sharing compared to an HMO.

Preferred Provider Organization (PPO) Medicare Advantage plans allow members to see any provider who accepts Medicare and the plan's terms, both in-network and out-of-network, without a referral. In-network care carries lower cost-sharing, while out-of-network care is still covered but at a higher cost-share to the member. PPOs are generally a better fit for people who travel frequently, split time between two locations, or want flexibility to see specialists without going through a primary care gatekeeper.

PFFS plans let you see almost any provider who agrees to accept the plan's payment terms on a visit-by-visit basis — there's no defined network in the traditional sense, but the provider still has to be willing to treat you under the plan's terms.

Private Fee-for-Service (PFFS) plans set their own payment rates and terms for providers, rather than relying on a contracted network. Members can generally see any Medicare-approved provider who agrees to accept the plan's payment terms and conditions for that specific service. PFFS plans have become relatively rare in many markets compared to HMOs and PPOs, but they remain an option in some areas, particularly rural ones with thinner provider networks.

SNPs are Medicare Advantage plans built specifically for people with certain circumstances — like having both Medicare and Medicaid, living with a chronic condition like diabetes or heart failure, or living in a nursing home. You have to actually meet the qualifying criteria to enroll.

Special Needs Plans are a category of Medicare Advantage plan restricted to specific populations, and come in three main types: Dual Eligible SNPs (D-SNPs) for those with both Medicare and Medicaid, Chronic Condition SNPs (C-SNPs) for those with specific qualifying chronic conditions such as diabetes, heart failure, or chronic kidney disease, and Institutional SNPs (I-SNPs) for those residing in or requiring the level of care provided by a long-term care facility. SNPs tailor their provider networks, formularies, and care coordination programs to the needs of their specific qualifying population.

Many plans advertise a $0 monthly premium, and that's real — but it doesn't mean the coverage is free. You still pay your Part B premium, and you'll likely still see costs through copays, coinsurance, and deductibles when you actually use care.

Many Medicare Advantage plans are available with a $0 monthly premium, where the carrier accepts the CMS payment as full compensation for managing the basic benefit, sometimes using rebate dollars to buy down the premium. However, the enrollee must continue paying their Part B premium regardless of which Medicare Advantage plan they choose, and a $0 premium plan still carries its own deductibles, copays, and coinsurance for actual services used.

Yes — and this is one of the biggest practical differences from Original Medicare. Every Medicare Advantage plan has a yearly limit on what you'd pay out of pocket for covered Part A and Part B services; once you hit it, the plan picks up 100% of those costs for the rest of the year.

Unlike Original Medicare, which has no out-of-pocket maximum, every Medicare Advantage plan is required to include a Maximum Out-of-Pocket (MOOP) limit for in-network Part A and Part B covered services. Once a member's cost-sharing for the year reaches that limit, the plan covers 100% of further in-network Part A/B costs for the remainder of the plan year. PPO plans typically have a separate, higher combined MOOP that includes out-of-network spending.

A copay is a flat dollar amount for a specific service — like $20 for a primary care visit. Coinsurance is a percentage of the cost instead, so it can vary depending on how expensive the actual service turns out to be.

Medicare Advantage plans use a mix of copayments (fixed dollar amounts charged for a specific service, such as $0-$50 for a primary care visit) and coinsurance (a percentage of the allowed cost, commonly used for services like durable medical equipment or some specialist visits). Plans publish these amounts service-by-service in their Summary of Benefits, and the mix of copay versus coinsurance items can differ meaningfully between two plans that look similar on the surface.

The most common surprises are out-of-network costs on a PPO, going to a specialist without realizing a referral was needed on an HMO, and not checking whether a specific drug is on the plan's formulary before assuming it's covered the same way it was on the old plan.

Common sources of unexpected cost for new Medicare Advantage enrollees include: receiving out-of-network care on a PPO without realizing the higher cost-share applied, skipping a required referral on an HMO plan, assuming dental/vision/hearing 'extra benefits' have no limits when they typically carry their own annual caps, and not checking whether existing prescriptions are on the plan's formulary at the same tier as before. A thorough plan comparison before enrolling — checking the specific doctors, specific medications, and specific anticipated procedures against the plan's actual documents — prevents the large majority of these surprises.

Maybe — it depends entirely on whether that specific doctor is in that specific plan's network. The only way to know for sure is to check the plan's current provider directory, not assume based on what other plans cover.

Whether a member can keep their current doctors after enrolling in a Medicare Advantage plan depends entirely on whether those providers participate in that specific plan's network for that specific year. Provider networks can and do change year to year, even for plans the person was previously enrolled in, so this should be verified directly against the current plan year's provider directory — ideally by calling the doctor's office to confirm directly, since online directories aren't always fully up to date.

Generally, HMO plans require a referral from your primary care doctor before you see a specialist, while PPO plans typically don't. But this can vary, so it's worth confirming for the exact plan in question.

Referral requirements are primarily determined by plan type: most HMO plans require a referral from the member's designated primary care provider before specialist visits are covered, while most PPO plans do not require referrals at all. However, individual plans can vary, and certain services (such as annual wellness visits, certain preventive screenings, or emergency care) are typically exempt from referral requirements even on HMO plans.

No — emergency care is covered regardless of network, anywhere in the U.S., on every Medicare Advantage plan. You're never penalized for going to the nearest emergency room in a true emergency.

Federal rules require all Medicare Advantage plans to cover emergency services regardless of whether the hospital or provider is in-network, and regardless of where in the United States the emergency occurs. Members should never delay seeking emergency care over network concerns. Urgently needed care while temporarily outside the plan's service area is also generally covered, though the specific cost-sharing can differ from a true emergency room visit.

Don't just trust an online directory — call the doctor's office directly and ask if they're currently contracted with that specific plan, for that specific year. Directories can lag behind reality.

The most reliable way to verify network participation is to contact the provider's office directly and ask whether they are currently in-network with the specific plan (not just the carrier generally) for the current plan year, since carriers can offer multiple plans with different networks. Online provider directories are a useful starting point but are not always current, and CMS itself has flagged directory accuracy as an ongoing industry issue.

Many do, which is a big part of their appeal — but these benefits usually come with their own annual dollar limits and specific covered services, so 'covered' doesn't always mean 'covered the way you'd expect.'

Original Medicare provides very limited dental, vision, and hearing coverage, which is one of the main reasons Medicare Advantage plans build in these benefits as a differentiator. Coverage commonly includes routine cleanings and exams, eyeglasses or contact allowances, and hearing aid allowances — but nearly always with annual dollar caps, specific in-network providers for these services, and limits on frequency (e.g., one routine cleaning every six months).

Many plans include a free gym membership program (often branded names like SilverSneakers or similar), giving access to a network of participating gyms and sometimes online fitness classes, at no extra cost.

Many Medicare Advantage plans include a fitness benefit, frequently delivered through a third-party fitness network program, providing access to a network of participating gyms and fitness facilities along with group classes, often including options for at-home or virtual fitness programming. The specific program and participating gym list vary by plan and by region.

Some plans give you a set dollar amount every month or quarter to spend on everyday health items — things like vitamins, pain relievers, or bandages — through a specific catalog or card.

An over-the-counter (OTC) allowance is a benefit included in some Medicare Advantage plans that provides a fixed dollar amount on a monthly or quarterly basis to purchase approved over-the-counter health-related items, typically through a specific catalog, an approved retail network, or a dedicated benefit card. Unused allowance amounts generally do not roll over indefinitely and may expire at the end of each benefit period, depending on plan rules.

Beyond dental/vision/hearing and fitness, some plans offer things like non-emergency transportation to medical appointments, meal delivery after a hospital stay, and even allowances for groceries or utilities for certain qualifying plans.

In addition to dental, vision, hearing, and fitness, Medicare Advantage plans have increasingly used CMS flexibility around 'Special Supplemental Benefits for the Chronically Ill' (SSBCI) and general supplemental benefits to offer things like non-emergency medical transportation, post-discharge meal delivery, in-home support services, and in some cases allowances for groceries, utilities, or pest control for members meeting specific health criteria. Availability of these richer benefits is highly plan- and region-specific, and some are restricted to members with qualifying chronic conditions.

MAPD just means a Medicare Advantage plan that has prescription drug coverage built right in, so you don't need a separate standalone Part D plan. Most Medicare Advantage plans today are MAPDs.

A Medicare Advantage Prescription Drug plan (MAPD) is a Medicare Advantage plan that includes Part D prescription drug coverage bundled into the same plan, as opposed to a Medicare Advantage plan with no drug coverage (an 'MA-only' plan) that would require pairing with a standalone Part D plan, if drug coverage is wanted at all. The large majority of Medicare Advantage plans on the market today are MAPDs.

A formulary is just the plan's list of which drugs it covers. Drugs get sorted into tiers, and lower tiers (usually generics) cost you less out of pocket than higher tiers (usually brand-name or specialty drugs).

A formulary is a plan's list of covered prescription drugs, organized into tiers that determine the member's cost-sharing for each medication. Lower tiers (typically preferred generics) carry the lowest copays, while higher tiers (non-preferred brand-name drugs, and specialty tiers for very high-cost medications) carry progressively higher cost-sharing, often shifting from a flat copay to a percentage-based coinsurance at the specialty tier. Formularies and tier placement can change from year to year, even for a plan a member has used for multiple years.

Prior authorization means the plan wants your doctor to confirm, in advance, that a specific medication is medically necessary before it'll pay for it. It's mostly used for higher-cost drugs or ones with safety concerns.

Prior authorization is a utilization management tool requiring the prescribing provider to submit documentation justifying medical necessity before the plan will cover certain medications, typically higher-cost drugs, drugs with significant safety considerations, or drugs that have lower-cost alternatives the plan wants tried first. A related tool, step therapy, requires a member to try a lower-cost medication before the plan will approve a more expensive alternative, unless the lower-cost option is contraindicated.

The overall structure of deductible, initial coverage, and catastrophic coverage still applies, but recent law changes have significantly reshaped how much people pay as they move through these phases, including a cap on total annual out-of-pocket drug spending.

Part D benefit design (which applies to the drug portion of MAPD plans as well) has been substantially restructured by the Inflation Reduction Act, including the elimination of the traditional 'donut hole' coverage gap phase as it existed for years and the introduction of a hard cap on annual out-of-pocket prescription drug spending. Because these mechanics have changed significantly and continue to be phased in, exact current-year phase thresholds and the out-of-pocket cap amount should always be confirmed against current CMS guidance rather than older reference material.

CMS scores every Medicare Advantage plan from 1 to 5 stars based on quality and member experience — things like how well the plan manages chronic conditions, customer service, and member complaints. It's a genuinely useful, independent way to compare plans beyond just price.

CMS assigns Star Ratings, on a scale of 1 to 5, to Medicare Advantage plans annually, based on a range of quality measures including clinical outcomes for chronic condition management, preventive care delivery, member satisfaction surveys, customer service responsiveness, and complaint/appeal volume. Ratings are published each fall ahead of AEP and are intended to give beneficiaries an independent, standardized way to compare plan quality beyond marketing materials.

Yes — if a 5-star-rated Medicare Advantage plan is available in someone's area, they get a special one-time opportunity during the year to switch into it, outside of the normal enrollment windows.

CMS offers a Special Enrollment Period allowing a beneficiary to enroll in a Medicare Advantage plan (or Part D plan) that has received an overall 5-star rating, available once during the part of the year when 5-star plans can be elected, separate from the standard AEP or MA OEP windows. This SEP exists specifically to make top-quality plans more accessible regardless of the calendar.

No — star ratings are a great quality signal, but they don't tell you whether your specific doctors are in-network or whether your specific medications are covered well. A 5-star plan that doesn't include your cardiologist isn't actually the best plan for you personally.

While star ratings provide a valuable, standardized quality signal, they reflect plan-wide performance across the carrier's membership and do not account for an individual's specific provider relationships, medication needs, or personal cost-sharing preferences. The most appropriate plan recommendation weighs star ratings alongside network match, formulary fit, total expected annual cost, and supplemental benefits relevant to that specific person — not star rating in isolation.

Because plans change every year — premiums, formularies, networks, and benefits can all shift, sometimes significantly, even if you never actively chose to change anything. The plan that was perfect last year might not be this year.

Medicare Advantage plans are re-filed and can be substantially redesigned by the carrier every plan year — premiums, cost-sharing, formularies, provider networks, and supplemental benefits can all change, sometimes significantly, without the member taking any action. CMS requires carriers to send an Annual Notice of Change each fall specifically so members can review what's different before AEP, but many people don't read it closely. An annual plan review during AEP, checking current doctors and medications against the upcoming year's plan documents, is the best protection against being caught off guard by these changes.

When you enroll in a new plan, it automatically cancels your old one — you don't have to separately call and disenroll from the old plan. The new plan takes effect, typically, on the first of the next month or January 1 if it's an AEP election.

Enrolling in a new Medicare Advantage plan automatically triggers disenrollment from the prior plan; no separate disenrollment step is required from the member. Coverage start dates depend on the election period used — AEP elections take effect January 1, while elections made during a Special Enrollment Period typically take effect the first of the month following the election, though some SEPs have different effective date rules.

Not necessarily — this is one of the trickiest parts of Medicare. Outside of certain protected situations (like being within your first 12 months of Medicare Advantage), going back to Medigap can require medical underwriting, meaning you could be charged more or even denied based on health.

Returning to Original Medicare from a Medicare Advantage plan does not automatically guarantee the right to purchase a Medigap policy without medical underwriting, except in specific protected circumstances — most notably a 'trial right' available to those who tried Medicare Advantage for the first time within their first 12 months of Medicare Part A and B eligibility, and certain other federally or state-protected situations. Outside of a guaranteed-issue right, applying for Medigap after time on Medicare Advantage can involve medical underwriting, which could result in a higher premium or denial based on health history. This is one of the most consequential and least understood aspects of the Medicare Advantage versus Medigap decision and should be discussed clearly before someone initially chooses Medicare Advantage.

Yes, in specific situations — most commonly if they move outside the plan's service area, lose Medicare Part A or B entitlement, don't pay premiums, or for an SNP, stop meeting the plan's qualifying criteria (like losing Medicaid eligibility for a D-SNP).

Involuntary disenrollment from a Medicare Advantage plan can occur if a member permanently moves outside the plan's service area, loses Part A or Part B entitlement, fails to pay plan premiums after required notice, provides fraudulent enrollment information, or — specific to Special Needs Plans — no longer meets the SNP's qualifying criteria (for example, losing Medicaid eligibility for a D-SNP, after applicable grace periods). Members facing involuntary disenrollment typically have appeal rights and should be directed to the plan's specific notice for next steps.

Medicare Advantage tends to have a lower (often $0) monthly premium but more variable costs depending on how much care you actually use. Medigap has a higher monthly premium but very predictable, low costs when you actually need care.

The core tradeoff between Medicare Advantage and Medigap is predictability versus premium. Medicare Advantage plans typically have low or $0 premiums but variable cost-sharing tied to actual utilization, bounded by an annual out-of-pocket maximum. Medigap policies carry a higher, standardized monthly premium (which increases over time) but largely eliminate cost variability for Medicare-covered services, since the policy picks up most or all of Original Medicare's cost-sharing. Someone who rarely uses care may pay less overall on Medicare Advantage; someone with frequent or expensive care needs may find Medigap's predictability worth the higher premium.

Medigap works alongside Original Medicare, so you can see any provider nationwide who accepts Medicare — no networks at all. Medicare Advantage, especially HMOs, restricts you to a defined network and service area.

Medigap policies supplement Original Medicare and impose no provider network of their own — a Medigap policyholder can see any provider in the United States who accepts Medicare, with no referrals and no network restrictions. Medicare Advantage plans, particularly HMOs, restrict members to in-network providers within a defined service area for non-emergency care, though PPO plans offer more (but not unlimited) out-of-network flexibility. This distinction is often decisive for people who split time between two states, travel extensively, or have strong existing relationships with specific specialists who may not be in every network.

The big ones: How often do they expect to need care? Are their current doctors locked into one network? Do they travel or split time between states? And can they comfortably afford a higher fixed monthly premium versus more variable but capped costs?

A practical decision framework weighs several client-specific factors rather than a generic 'which is better' comparison: anticipated frequency and cost of care (favoring Medigap's predictability for heavy utilizers), specific provider relationships and whether they're tied to one network (favoring Medigap's universal access if key providers aren't reliably in MA networks), travel patterns and multi-state living situations (favoring Medigap or a PPO over an HMO), budget comfort with a fixed higher premium versus variable-but-capped costs, and interest in supplemental benefits like dental/vision/hearing that only Medicare Advantage typically bundles in. There is no universally correct answer — the right recommendation depends on weighing these factors against that specific person's actual situation and goals.

At minimum: their current doctors and specialists, their full medication list, how often they travel or split time between locations, their budget comfort level, and which supplemental benefits (dental, vision, fitness, etc.) actually matter to them personally.

A thorough needs assessment for a Medicare Advantage recommendation should document the client's current providers and specialists (to check network fit), complete current medication list (to check formulary and tier fit), travel patterns and any multi-state living arrangements (to assess network type fit), budget tolerance for premium versus variable cost-sharing, and which supplemental benefit categories genuinely matter to that individual rather than assuming generic priorities. Skipping any of these categories increases the risk of an unsuitable recommendation that surfaces as a problem only after the client tries to use the plan.

At minimum, clients should hear that you don't represent every plan or carrier available in their area, and be pointed to Medicare.gov or 1-800-MEDICARE as an unbiased source for comparing all their options — not just the ones you're presenting.

CMS marketing guidelines require Medicare Advantage marketing materials and presentations to include disclosure that the agent does not offer or is not contracted with every plan available in the service area, along with guidance directing the beneficiary to Medicare.gov, 1-800-MEDICARE, or their State Health Insurance Assistance Program (SHIP) for unbiased help comparing all available options. Materials and conversations should also avoid implying government endorsement and must accurately represent the agent's relationship to Medicare (independent agents are not employees or representatives of CMS or the federal government).

Don't promise specific benefits will definitely be available next year, don't imply you represent every plan in the area, and never suggest a recommendation is coming from Medicare itself rather than from you as an independent agent.

Common compliance pitfalls include implying a current year's specific benefits or premium will necessarily continue unchanged into future years, failing to clearly disclose limited carrier/plan representation, using language that could be construed as the agent speaking on behalf of Medicare or CMS rather than as an independent licensed agent, and recommending a plan switch primarily because of a personal incentive (such as commission structure) rather than genuine client fit. Documenting the needs assessment and the rationale behind a specific recommendation is good practice both for compliance and for genuinely better client outcomes.

Reach out before AEP every year, re-check their current doctors and medications against the upcoming plan year's documents, and proactively flag any meaningful changes — don't wait for the client to notice a problem after the new plan year has already started.

A strong annual review process contacts every Medicare Advantage client ahead of AEP each year, re-verifies their current medications against the upcoming plan year's formulary, re-verifies key providers against the upcoming network, and reviews the plan's Annual Notice of Change for any benefit, premium, or cost-sharing changes worth flagging. This proactive approach catches formulary or network changes before they become a problem in January, rather than reactively fielding a confused call after the client discovers an issue at the pharmacy or doctor's office.
