What changed: in July 2026, Humana announced additional Medicare Advantage market exits for plan year 2027, its second consecutive year of retrenchment. Presbyterian Health Plan in New Mexico and Providence Health Plan in Washington are leaving the MA market entirely for 2027.

Members in every affected county will learn their fate by Sept. 30, 2026, the CMS deadline for Annual Notice of Change and non-renewal materials. They then re-shop all at once during the 2027 Annual Enrollment Period, Oct. 15 to Dec. 7, 2026. For provider organizations, a plan exit is not a payer-mix curiosity. It is a receivables runoff event with a hard end date, and the mapping work has to happen before the notices land, not after.

The 2027 exit wave in four numbers

2 plans Presbyterian Health Plan (New Mexico) and Providence Health Plan (Washington) exit Medicare Advantage entirely for 2027 Payer exit notices

Where the 2027 exits are certain, and where they are still hidden

Two states already know they are losing an entire MA carrier for 2027. Everywhere else, the honest answer is that the county list is sealed until the Sept. 30 notices arrive. Humana has said additional markets are exiting; the exact contract-county detail reaches your patients before it reaches most revenue cycle teams. That gap is the operational risk.

Full-carrier MA exit confirmed for 2027: Providence Health Plan (WA), Presbyterian Health Plan (NM) Exposure unresolved until Sept. 30, 2026 notices name the counties
The Humana overlay: Humana's July 2026 announcement covers additional 2027 market exits on top of last year's retrenchment, but the contract-county detail becomes concrete only in the non-renewal notices due by Sept. 30, 2026. If Humana is a top-five payer for you anywhere, treat every Humana contract as unconfirmed until you have read its notice.

The clock between now and runoff

July 2026Humana announces additional 2027 MA market exits, its second straight retrenchment year. Presbyterian (NM) and Providence (WA) confirm full MA exits.
Sept. 30, 2026CMS deadline for ANOC and non-renewal notices. The exact exiting contract-county list is now in your patients' mailboxes.
Oct. 15, 20262027 AEP opens. Displaced members begin choosing new plans, and your future payer mix starts moving.
Dec. 7, 2026AEP closes. By this date the destination of every displaced member is largely decided.
Jan. 1, 2027Exiting contracts stop generating new dates of service. Everything still unpaid becomes a runoff book with a shrinking payer operation behind it.

Why an exit is a receivables event, not just an enrollment story

When a plan non-renews, three things happen to your revenue at once. The old book stops growing but still has to be collected, worked against a payer that is winding down its market presence. The member shows up in January with a new card, a new ID, a new network status, and often new authorization rules, which resets your front-end risk on the same patient. And your contract-county concentration decides how much of this hits you: two organizations with identical MA revenue can have completely different exposure depending on which counties that revenue sits in.

Step 1Exit announcedHumana's July 2026 announcement sets the wave in motion; NM and WA lose a full carrier each.
Step 2Notices landBy Sept. 30, 2026, members hold the county-level truth. Collect these notices; they are your exposure map.
Step 3Members re-shopOct. 15 to Dec. 7, 2026: displaced members pick new payers, and your 2027 mix is decided in 54 days.
Step 4Runoff clockFrom Jan. 1, 2027, the exiting book only shrinks. Every unworked claim ages against a hard end date and contract-specific filing clocks.

The operator to-do list, in order

  1. Map MA revenue by contract by county now, before Sept. 30. A payer-level report hides the exposure; the exit happens at the contract-county level.
  2. Flag every agreement with Humana, Presbyterian Health Plan, and Providence Health Plan, and pull the current AR balance sitting on each one.
  3. Collect the notices your patients receive. The ANOC and non-renewal letters name the exact exiting counties; make your registration team a listening post.
  4. Accelerate AR on exiting contracts. Treat the runoff book as a dated asset: work denials and underpayments on those contracts first, while the payer's operations are still fully staffed.
  5. Prepare the front end for January. Every displaced member returns with a new payer, so plan for a re-verification surge: eligibility, benefits, and authorization rules all reset on Jan. 1, 2027.
  6. Model where displaced members land. Check your network status with the likely receiving plans in the affected counties before AEP opens on Oct. 15, not after it closes on Dec. 7.

Turn the exit wave into a controlled runoff

ASP-RCM Solutions builds exactly this playbook for provider organizations: contract-county revenue mapping before the notices land, accelerated AR workdown on exiting payer books, and high-volume eligibility re-verification when displaced members return in January with new cards. If Medicare Advantage is a material share of your revenue, the window to prepare is the one between now and Sept. 30, 2026.
