Humana Will Exit More Medicare Advantage Plans in 2027 — What It Means for New Mexico
About 600,000 members nationwide will need new coverage. No county list exists yet — here's New Mexico's actual exposure, and the rights that protect you if your plan is discontinued.
The bottom line
- On July 29, 2026, Humana told investors it will exit additional Medicare Advantage plans in 2027, affecting roughly 600,000 members nationwide — about 8% of its enrollment. No plan, county, or state list has been published.
- New Mexico's exposure is real: per the official CMS CY2026 landscape, Humana is on the shelf in 29 of the 33 NM counties with any standard Medicare Advantage drug plan — including half of San Juan County's 8 plans.
- This lands on top of Presbyterian's already-announced 2027 exit (~30,000 NM members) — two carriers reshaping the same plan year.
- If your plan is discontinued you have strong rights: the October 15, 2026–December 7, 2026 enrollment window, a December 8 through the last day of February Special Enrollment Period, and usually a no-health-questions Medigap window.
- Nothing changes in 2026 — the right move now is to read your Annual Notice of Change when it arrives this fall.
On its July 29, 2026 earnings call, Humana — one of the two largest Medicare Advantage insurers in the country — said it will shut down more of its Medicare Advantage plans for the 2027 plan year, affecting about 600,000 of its roughly 7.2 million members. Which plans and counties has not been announced, and your 2026 coverage is unchanged through December 31. The practical takeaway for New Mexico enrollees: nothing needs to happen today, but this fall's plan mail deserves a careful read — especially with Presbyterian's separate exit already reshaping the 2027 shelf.
What exactly did Humana announce?
Humana told investors it will exit Medicare Advantage plans covering about 600,000 members — roughly 8% of its enrollment — for the 2027 plan year, as it works toward a pre-tax margin target of at least 3% by 2028. CFO Celeste Mellet framed the exits as pruning lower-return plans so benefits can stay stable in the plans the company keeps, and said Humana expects to recapture a meaningful share of affected members in its remaining plans. This is the second consecutive year of trimming: for 2026, Humana withdrew from three states and 194 counties nationally — and still grew, because the plans it kept stayed competitive. Carriers redrawing their county maps each fall is now a recurring feature of the Medicare Advantage market.

How exposed is New Mexico, county by county?
Nobody knows which counties are on the 2027 list — the first public answer arrives when CMS posts the 2027 plan landscape in late September, and affected members get written non-renewal notices in the fall. What we can measure is today's footprint. From the official CMS CY2026 landscape file (standard MA-PD plans, excluding Special Needs Plans), here is how much of each major New Mexico county's shelf is Humana's:

The pattern that matters: in metro counties like Bernalillo and Sandoval, a Humana exit would sting but leave ten other carriers competing for your enrollment. In San Juan County, Humana is half the shelf — 4 of 8 plans — and in Eddy County it is one of only two carriers. Rural New Mexico simply has less cushion, which is why Farmington-area and southeastern-NM enrollees should watch this fall's mail most closely.
What are my options if my plan is discontinued?
| Your 2027 option | Who it tends to fit | The key thing to check first |
|---|---|---|
| A different Medicare Advantage plan in your county | People happy with the Advantage model who want an all-in-one plan, often with a $0 or low premium | That your doctors are in-network and your drugs are on that specific plan's formulary — carrier lineups are shifting for 2027 |
| Original Medicare + Medigap + Part D | People who want any Medicare-accepting doctor nationwide and prefer predictable costs over copays | Your guaranteed-issue rights: a discontinued plan usually opens a no-underwriting window to buy Medigap — with a 63-day clock |
| A Special Needs Plan (D-SNP), if you have Medicare and Medicaid | Dual-eligible New Mexicans | That you meet Medicaid eligibility, which these plans require |

Schedule a conversation →What rights protect me when a plan leaves?
Medicare's rules here are genuinely protective, because plan exits happen every year. You never lose Medicare itself — a plan exit ends a private contract, not your Part A and Part B. From there, three protections do the work:
- The Annual Enrollment Period (October 15, 2026–December 7, 2026): pick any 2027 plan available in your county, effective January 1, 2027.
- A dedicated Special Enrollment Period: per Medicare.gov, members of a plan whose contract isn't renewed can switch to another plan between December 8 through the last day of February.
- Guaranteed-issue Medigap rights: when an Advantage plan leaves Medicare or your area and you return to Original Medicare, you generally have the right to buy Medigap Plan A, B, C, D, F, G, K, or L with no medical underwriting, within 63 days after your coverage ends (Medicare.gov). Plans C and F are limited to people who were Medicare-eligible before January 1, 2020. Keep the non-renewal letter — it's your proof.
That third right is easy to underrate. Outside protected windows, New Mexico Medigap carriers can ask health questions and decline or rate an application. A plan exit is one of the few events that reopens the no-health-questions door — for someone who chose Medicare Advantage years ago and has picked up health conditions since, that window can be the most valuable thing in this entire story.
What should I do, and when?
- Now: nothing rash — there is no 2027 lineup to switch to yet. Confirm your plan has your current mailing address, and keep a current list of your doctors and prescriptions.
- Late September: CMS publishes the 2027 plan landscape — the first county-by-county view of next year's options.
- By early October: your Annual Notice of Change arrives; discontinued plans send non-renewal letters. Read the letter — it is the official word, not a headline.
- October 15, 2026–December 7, 2026: compare and enroll for 2027. If your plan was discontinued, weigh both doors — another Advantage plan, or Original Medicare + Medigap + Part D through the guaranteed-issue window.
- December 8 through the last day of February: the backstop Special Enrollment Period if your plan was non-renewed and you need more time.
Enrollment window: Medicare.gov Open Enrollment. Non-renewal SEP: Medicare.gov Special Enrollment Periods.

Questions New Mexico members are asking
Is Humana leaving Medicare Advantage in New Mexico in 2027?
That has not been announced. On its July 29, 2026 earnings call, Humana said it will exit additional Medicare Advantage plans in 2027 — affecting roughly 600,000 members nationwide, about 8% of its enrollment — but it has not published which plans, counties, or states are affected. The county-level answer for New Mexico becomes public when CMS releases the 2027 plan landscape in late September and plans mail their fall notices. Until then, nobody can tell you whether a specific New Mexico plan is staying or going.
How big is Humana in New Mexico today?
Meaningful, and bigger in some counties than others. Per the official CMS CY2026 landscape file, Humana offers standard Medicare Advantage drug-coverage (MA-PD) plans in 29 of the 33 New Mexico counties that have any MA-PD offering. In San Juan County (Farmington), Humana supplies 4 of the 8 plans on the shelf — half the county's options — while in Albuquerque's Bernalillo County it's 8 of 29, with ten other carriers still competing.
How does this relate to Presbyterian ending its Medicare Advantage plans?
They're separate decisions by separate companies, but they land on the same calendar. Presbyterian announced in June 2026 that it will discontinue most of its Medicare Advantage plans for 2027, affecting about 30,000 New Mexico members. Humana's July announcement means a second major carrier is also trimming plans somewhere for 2027. If both changes touch your county, the 2027 shelf will look noticeably different from 2026's — which makes actually reading your fall plan mail, and comparing during the enrollment window, more important than in a typical year.
What happens if my Medicare Advantage plan is discontinued at the end of 2026?
You never lose Medicare itself — a plan exit ends a private contract, not your Part A and Part B. You can pick a new plan during the Annual Enrollment Period (October 15, 2026–December 7, 2026), and per Medicare.gov, members of a plan whose contract isn't renewed also get a Special Enrollment Period from December 8 through the last day of February to switch to another plan. If you take no action, you're returned to Original Medicare on January 1 — but note that Original Medicare alone has no drug coverage and no out-of-pocket maximum, so doing nothing is also a decision.
Can I buy a Medicare Supplement (Medigap) plan if my Advantage plan goes away?
Usually, yes — with no health questions. When a Medicare Advantage plan leaves Medicare or stops serving your area and you return to Original Medicare, federal guaranteed-issue rights generally let you buy Medigap Plan A, B, C, D, F, G, K, or L sold in New Mexico (Plans C and F only if you were Medicare-eligible before January 1, 2020), within 63 days after your coverage ends. Outside windows like this, New Mexico carriers can apply medical underwriting — so for someone with health conditions, a plan exit can be a rare second chance at Medigap. Keep the non-renewal letter as proof.
Is New Mexico Medicare Help connected to Humana or the government?
No. New Mexico Medicare Help is a licensed independent insurance agency. We are not connected with or endorsed by Humana, the U.S. government, or the federal Medicare program, and mentioning a carrier is factual reporting, not an endorsement. We do not offer every plan available in your area. For all of your options, contact Medicare.gov or 1-800-MEDICARE.
