How Do I Compare Medicare Advantage Plans for 2027?

Most plans on the list have the same premium, so the premium cannot be what you compare. Here is the order that works, where each answer is found, what one county's 2027 list shows about how far plans differ, and how we do the same comparison for the plans we offer.

To compare Medicare Advantage plans, check them against your own care in a fixed order: are your doctors in the network, are your prescriptions on the drug list, what will the year cost in total, and what is the most you could pay in a bad year. Only then look at extras. The order matters because most plans look alike on the one number people check first. In Bernalillo County, CMS lists 21 general-enrollment Medicare Advantage plans for 2027, and 17 of them have a $0 monthly plan premium. The same plans' yearly out-of-pocket maximums differ by as much as $4,200. The Annual Enrollment Period runs from October 15, 2026 through December 7, 2026.

What do I need before I start?

A comparison is only as good as what you put into it. These take a few minutes to collect, and they are the same things we ask for on our plan comparison page.

• Your ZIP code. Plan availability is set by county.
• Every doctor and specialist you see, plus the hospital you would want to use.
• Every prescription with its dose, including the ones you take only occasionally.
• Your pharmacy, and whether mail order would suit you.
• Your current plan's paperwork. The Annual Notice of Change, which plans send by September 30, lists what is changing in January. The Evidence of Coverage follows by October 15.

If your plan is ending rather than changing, the paperwork is a non-renewal notice instead, and the starting point is Presbyterian Medicare Advantage ending: your options in Albuquerque.

What should I compare, and in what order?

Here is how to compare, step by step. The items at the top are the ones you cannot fix after January 1 without changing plans again.

Sources: the order is the one on our plan comparison page; Medicare.gov — Your Yearly Medicare Review gives the same starting points, plans that "cover your prescription drugs" and "include the providers you want in their networks, like your doctor or pharmacy."

Why not start with the premium?

Because it barely separates one plan from another. We counted the general-enrollment plans CMS lists in Bernalillo County for 2027, leaving out the 15 Special Needs Plans that require Medicaid or a qualifying condition. This is what the list shows.

CMS notes the data are subject to change as contracts are finalized. These are ranges across a list, not a description of any one plan, and the median is the middle plan on the list.

A $0 premium is not the same as no cost. The handbook says some plans have a $0 premium "but you still may pay the Part B premium," and what you pay also depends on "the amount you pay for each visit or service, like your copayment or coinsurance." The full 2027 list for Albuquerque, counted by organization and plan type, is in Medicare Advantage plans in Albuquerque for 2027: what's available?

How do I check my doctors?

Check each one by name, for the specific plan and the specific year. A network belongs to a plan, not to an insurance company, so a doctor can be in one plan from a company and out of another. The plan type tells you how much an out-of-network doctor would matter.

• HMO. The handbook: "You generally must get your care and services from doctors, other health care providers, or hospitals in the plan's network," apart from emergency care, out-of-area urgent care and temporary out-of-area dialysis. In most cases you choose a primary care doctor and need a referral to see a specialist.
• HMO Point-of-Service. Some HMOs "may let you get some out-of-network services for a higher copayment or coinsurance."
• PPO. You can "use out-of-network providers for covered services, usually for a higher cost, if the provider agrees to treat you." In most cases no referral is needed.

Then confirm it twice. The handbook says that on Plan Finder "you can add the providers who are most important to you, and your plan search results will show if they're in network with the plans you're considering. You can also contact your provider directly to find out if they're in network." Do both, and ask the office about the plan by its full name. Networks also move during the year: "Providers can join or leave a plan's provider network any time during the year." The five-step version of this check is in How to keep your doctor when your Medicare plan ends.

How do I check my prescriptions?

Drug by drug, with the dose. For each one, find three things on the plan's drug list, which plans call a formulary: whether it is covered, which tier it is in, and whether it carries a coverage rule. The handbook names the rules: prior authorization, quantity limits and step therapy, where "you may need to try one or more similar, lower-cost drugs before the plan will cover the prescribed drug."

Then check the pharmacy. The handbook notes your costs depend on "which pharmacy you use (whether it offers preferred or standard cost sharing, is out of network, or is mail order)." A plan can cover your drug and still cost more at the pharmacy you use now.

Two federal limits apply to every plan with drug coverage. Your out-of-pocket costs for covered Part D drugs are capped at $2,400 in 2027. And a plan may have a drug deductible: the 19 Bernalillo County general plans with drug coverage list deductibles from $200 to $700 for 2027. This is the step most people skip. KFF found that 82% of people in Medicare Advantage drug plans did not compare their plan's drug coverage with others during the 2021 open enrollment period. More on this step is in Keep your medications when your plan changes.

Sources: Medicare & You 2027 — Medicare drug coverage (Part D); Medicare.gov — Costs for Medicare drug coverage; CMS CY2027 Landscape file; KFF, September 26, 2024 (national figures for the 2022 survey year).

What does the out-of-pocket maximum tell me?

The most you would pay in a year for covered hospital and medical care. The handbook describes it as "the plan's yearly limit on your out-of-pocket costs for all Part A- and Part B-covered services. Once you reach this limit, you'll pay nothing for Part A- and Part B-covered services." Original Medicare on its own has no such limit, which is one of the main differences between the two.

Three details are easy to miss:

• It may be two numbers. The handbook says plans' limits "may include different limits for in-network and out-of-network services." The figures in the table above are in-network limits. In a PPO, ask for the combined limit too.
• It does not include Part D prescriptions. What you pay at the pharmacy counts toward the separate $2,400 drug cap, not toward the medical maximum.
• It does not include the premium, or extras such as dental work beyond what the plan covers.

A lower maximum is not automatically the better fit. A plan with a low maximum can have higher copays along the way or a narrower network. That is why this is step four and not step one: it answers "what is my worst year," after the first three steps have answered "what is my expected year."

Where do Star Ratings and extras fit?

After the steps above. The handbook says "Medicare uses ratings from 1–5 stars to help you compare plans based on quality and performance." CMS posts the 2027 Star Ratings on Medicare.gov on or around October 8, 2026, so a comparison done in the first week of October will not have them yet. A rating describes a plan's overall performance. It does not tell you whether your cardiologist is in the network.

Extras deserve a careful reading. The handbook's wording is that these benefits "are generally limited, so check with the plan before you join to find out what exactly is covered." A dental allowance has a yearly dollar limit and often a network of its own. Compare the limit, not the headline.

How do I use Medicare.gov Plan Finder?

Plan Finder at Medicare.gov/plan-compare is the one tool that lists every Medicare Advantage and drug plan in your county. 2027 plans are on it by October 1, 2026.

1. Enter your ZIP code and choose the kind of plan you want to look at.
2. Add your prescriptions and pharmacies. If you log in to your Medicare account, the handbook says you can "add your prescriptions and pharmacies to help you better compare Medicare health and drug plans in your area."
3. Add your providers, so the results show which plans list them as in network.
4. Narrow the list using steps one and two above before you look at cost.
5. Open the details of the few plans that remain and read the copays for the care you actually use.
6. Call to confirm the network with your doctor's office before you enroll.

If a screen is not your preference, 1-800-MEDICARE (1-800-633-4227) can help you compare plans by phone, 24 hours a day, and New Mexico's SHIP counselors at 1-800-432-2080 give one-on-one help without selling anything. The handbook adds that "a trusted agent or broker may also be able to help."

How do we compare plans?

The same way, with the limits stated up front. This is the process described on our plan comparison and annual coverage review pages.

• We start from your list, not from a plan: your ZIP, your doctors and hospital, your prescriptions with doses, and your pharmacy.
• We use the order above. Doctors, then prescriptions, then total yearly cost, then the out-of-pocket maximum, with extras last.
• We compare the plans we offer in your county. We do not offer every plan available in your area. For the full list, use Medicare.gov or call 1-800-MEDICARE (1-800-633-4227).
• You get a short list, typically two or three plans, with the reasoning and the trade-offs for each, not a catalogue.
• "Stay where you are" is a legitimate result. If your current plan still fits, we say so.
• We do it again each autumn, because premiums, drug lists and networks reset every January.
• It costs you nothing. Insurance companies pay our fee, and the plan premium is the same whether you enroll through us or on your own. How that works is in How do Medicare agents get paid in 2027?

One formality comes first. Federal marketing rules require an agent to record what you have agreed to discuss, called a Scope of Appointment, before talking about specific plans. It does not commit you to anything. You can also run Plan Finder yourself and bring us what you found. We would rather you did that than choose blind, and we are glad to check your work.

Sources: 42 CFR 422.2264(c) — Scope of Appointment; Medicare.gov — Plan marketing rules.

What goes wrong most often?

• Choosing by premium. Most of the list is tied at $0, as the table above shows.
• Choosing by an extra. A dental or grocery benefit is worth less than a specialist who is in network.
• Checking the insurance company instead of the plan. Networks and drug lists are set plan by plan.
• Leaving out the occasional drug. The inhaler you fill twice a year still has a tier.
• Using last year's answer. A network or drug list that fit in 2026 has to be checked again for 2027. Why is in Do I need to change my Medicare plan every year?
• Waiting for the last week. Enrolling by December 7, 2026 is what counts, but a directory question can take days to answer.

If a choice made this fall turns out wrong, there are limited second chances, laid out in Can I change my Medicare Advantage plan after December 7? An hour with your own list in October is the easier route.
