How to Keep Your Doctor When Your Medicare Plan Ends: A New Mexico Guide for 2027
With most Presbyterian Medicare Advantage plans ending, the doctor check — not the premium — is the step that decides whether January goes smoothly.
The bottom line
- Presbyterian is discontinuing most of its Medicare Advantage plans in New Mexico for 2027, affecting about 30,000 members. Your 2026 coverage — and your doctors — do not change this year.
- Whether you keep a doctor in 2027 depends on the network of the new plan you pick, not on the old plan going away.
- Before enrolling, verify every doctor in the new plan's provider directory and every prescription on its drug list — then confirm with the doctor's office directly.
- If a doctor isn't in any nearby network, Original Medicare (optionally with Medigap and a Part D plan) is accepted by any provider who takes Medicare.
- Make the choice during the Annual Enrollment Period, October 15, 2026–December 7, 2026, for January 1, 2027 coverage.
Losing a Medicare Advantage plan does not mean losing your doctor — it means your next plan's network decides who stays in-network. Presbyterian's decision to discontinue most of its Medicare Advantage plans for 2027 affects roughly 30,000 New Mexicans, and each of them will pick new coverage during the Annual Enrollment Period (October 15, 2026–December 7, 2026). The reliable way to keep your doctors is to check each candidate plan's provider directory against your own written list of providers — and to confirm with each office — before you enroll, not after. This guide walks through that check step by step.
Why does a plan change put your doctor in question?
Medicare Advantage plans work through provider networks: each plan contracts with specific doctors, clinics, and hospitals, and your costs are lowest (or coverage only applies) when you use them. When Presbyterian's plans end after December 31, 2026, those network contracts end with them. Your doctors aren't going anywhere — but whether they're "in-network" for you in 2027 depends entirely on which plan you join next.
The good news for New Mexico members is that networks overlap. Many physicians and medical groups in Albuquerque, Rio Rancho, Santa Fe, and across the state contract with several Medicare Advantage carriers at once, and every provider who accepts Medicare will see you if you return to Original Medicare. Presbyterian has also said its Dual Plus (D-SNP) plan continues for people who have both Medicare and Medicaid — we cover that path in our New Mexico D-SNP guide.

How do I check whether a 2027 plan covers my doctor? (5 steps)
- Write the list. Every provider you saw in the last two years: primary care, each specialist, your preferred hospital, and your pharmacy. Add every prescription with its dose. This one page becomes your measuring stick for every plan.
- Pull up the 2027 plans in your ZIP. When AEP opens on October 15, 2026, the official Medicare Plan Compare tool lists every Medicare Advantage and Part D plan offered in your county, with links to each plan's provider directory and drug list.
- Check each doctor in each candidate plan's directory. Search by the doctor's name — and verify the specific office location, since a physician can be in-network at one clinic and not another.
- Call the doctor's office to confirm. Directories can lag. Ask the billing desk: "Which 2027 Medicare plans do you expect to accept?" Offices field this question all fall — it's a normal call to make.
- Only then compare costs. Once two or three plans pass the doctor-and-drug check, weigh premiums, copays, and extra benefits. A low premium never offsets a plan that doesn't include the specialist you rely on.
If a doctor appears in no nearby network, use Medicare Care Compare to confirm they accept Medicare — if they do, the Original Medicare path below keeps them available to you.
Which coverage path makes keeping your doctor simplest?
Doctor access works differently under each of the three realistic paths for 2027. None is automatically right for everyone — the table below shows how each one treats the doctors on your list.
| 2027 path | How doctor access works | The check that matters |
|---|---|---|
| Another Medicare Advantage plan | You use that plan's network; out-of-network rules depend on plan type (HMO vs. PPO) | Every doctor listed in that specific plan's 2027 directory, at your location |
| Original Medicare + Part D (with or without Medigap) | Any provider in the U.S. who accepts Medicare — no network to check | That each doctor accepts Medicare; if adding Medigap, your guaranteed-issue rights and pricing |
| Presbyterian Dual Plus (D-SNP) — only if you have Medicare and Medicaid | Continues Presbyterian's network for dual-eligible members | Your Medicaid eligibility, which the plan requires |

Schedule a conversation →Why does the doctor check matter so much in Santa Fe County?
Because ongoing conditions mean ongoing relationships. In Santa Fe County, the CDC's PLACES 2023 estimates show how common chronic conditions are among adults — each one typically comes with a prescriber, a specialist, or a standing prescription that a new plan needs to cover on January 1. The more of these apply to you, the more the network and formulary details outweigh the headline premium.

Why should I check prescriptions at the same time?
A plan that includes every doctor on your list can still treat a medication differently — each plan sets its own formulary, pharmacy network, and copay tiers. Two federal figures are fixed no matter which plan you choose: in 2026, out-of-pocket costs for covered Part D drugs are capped at $2,100 per year, and the standard Part B premium is $202.90 per month. Everything else — which drugs are covered, at which pharmacy, at what tier — varies plan by plan, which is why the drug list check belongs in the same sitting as the doctor check. Plan Compare lets you enter your exact prescriptions and see estimated yearly drug costs under each plan.

What should I ask before I enroll in a 2027 plan?
Bring these six questions to any plan comparison — with an agent, with SHIP, or on your own:
- Is each of my doctors in this plan's 2027 directory, at the location where I actually see them?
- Is my hospital in-network, and how does the plan handle emergencies away from home?
- Is every prescription on the formulary, at what tier, and is my pharmacy preferred?
- Do my regular services (physical therapy, mental health, specialist visits) need referrals or prior authorization?
- If I'd rather keep full doctor flexibility, what would Original Medicare with a Medigap plan cost me — and do I have guaranteed-issue rights because my plan was discontinued?
- What is my worst-case year — the plan's maximum out-of-pocket — not just the monthly premium?

Questions New Mexico members are asking
Can I keep my doctor if my Presbyterian Medicare Advantage plan ends?
Often, yes — but it depends on the coverage you choose next. Many New Mexico physicians participate in more than one Medicare Advantage network, and any provider who accepts Medicare will see you under Original Medicare. The only way to know for certain is to check each 2027 plan's provider directory for each of your doctors before you enroll, and to confirm directly with the doctor's office that they expect to stay in that network next year.
How do I find out which 2027 plans include my doctor?
Make a written list of every doctor you see, then use Medicare.gov Plan Compare during the Annual Enrollment Period (October 15 – December 7, 2026) to view the plans offered in your ZIP code and check their provider directories. Cross-check by calling each doctor's billing office and asking which 2027 Medicare plans they expect to accept. A licensed independent agent can run the same doctor-and-drug check across carriers at no cost to you.
What if my doctor isn't in any Medicare Advantage network near me for 2027?
You can return to Original Medicare, which is accepted by any provider who takes Medicare, and pair it with a stand-alone Part D drug plan. Many people in that situation also consider a Medicare Supplement (Medigap) policy; because your plan is being discontinued, you may have a guaranteed-issue right to buy certain Medigap plans without health questions. Verify your specific rights and deadlines at Medicare.gov.
Do I need to check my prescriptions too, or just my doctors?
Check both at the same time. Each Medicare Advantage or Part D plan has its own formulary (covered-drug list), pharmacy network, and copay tiers, so a plan that covers all of your doctors could still handle a prescription differently. In 2026, your out-of-pocket costs for covered Part D drugs are capped at $2,100 for the year, but which drugs count as covered depends on the plan you pick.
When do I need to make the change?
Your 2026 coverage continues through December 31, 2026. Choose your 2027 plan during the Annual Enrollment Period, October 15 through December 7, 2026, for coverage starting January 1, 2027. Because your plan is being discontinued, you also generally qualify for a Special Enrollment Period with additional time — but enrolling during AEP avoids any scramble in January.
Is New Mexico Medicare Help connected to Presbyterian or the government?
No. New Mexico Medicare Help is a licensed independent insurance agency. We are not connected with or endorsed by Presbyterian, the U.S. government, or the federal Medicare program. For information on all of your options, contact Medicare.gov, 1-800-MEDICARE, or your State Health Insurance Assistance Program (SHIP).
