18 Payers Exiting Medicare Advantage in 2027: What Urgent Care Billing Teams Must Do Before January

How Do the 2027 Medicare Advantage Exits Affect Urgent Care Billing?

As of October 2026, 18 payers are exiting the Medicare Advantage market for 2027, according to CMS data reported by Becker’s Payer Issues on October 20, 2026. For urgent care centers, this means patients will arrive in January carrying cards for plans that no longer exist, and claims sent to those plans will deny unless the front desk confirms each patient’s new coverage at check-in.

• Who is leaving: The largest exits include BCBS Texas, Wellmark BCBS in Iowa and South Dakota, BCBS Oklahoma, BCBS North Dakota, and BCBS Montana.
• The January gap: Patients who do nothing move to Original Medicare on January 1, and anyone who picks a new plan in January stays on Original Medicare until February 1.
• What to do now: Flag affected patients, re-verify every Medicare patient in January, and map each replacement plan to its billing rules before claims go out.

What Changed for Medicare Advantage in 2027

On October 20, 2026, Becker’s Payer Issues reported that 18 payers are exiting Medicare Advantage for 2027, based on CMS plan data. Ten of the 18 are owned entirely or in part by health systems. Several other carriers, including Molina Healthcare, Horizon BCBS New Jersey, Elderplan, and Presbyterian Health Plan, will stay in Medicare Advantage only through special needs plans.

Earlier fall reporting listed 11 or 12 full exits, so counts vary by publication date and by how special needs plans are treated. The October 20 tally of 18 is the most recent named count as of this writing. Here are the exits with the largest 2026 footprints:

The list also includes ConnectiCare and CarePartners of Connecticut, Providence Health Plan in Oregon, Washington, and Orange County, California, WellSense Health Plan in New Hampshire, Aspirus Health Plan in Wisconsin, Saint Alphonsus Health Plan in Idaho, Memorial Hermann Health Plan and Sharp Health Plan, and Mass Advantage in Worcester County. Coverage under every exiting plan ends December 31, 2026.

Enrollees are now choosing replacement coverage during Medicare’s annual election period, October 15 through December 7, and that choice decides where January claims go.

Does the 2027 Medicare Advantage Exit Affect My Urgent Care Patients?

It does if your center sees Medicare patients in any county where an exiting plan operated. The heaviest impact falls on Texas, Oklahoma, Iowa, South Dakota, North Dakota, Montana, Mississippi, New Jersey, and Connecticut, but exits also touch New Mexico, Wisconsin, Idaho, New York, Oregon, Washington, California, New Hampshire, and Massachusetts.

One question we hear constantly from urgent care practice managers is how to know which patients are affected before they walk in. Urgent care makes this harder than primary care. A family practice can mail its Medicare panel a reminder in November. An urgent care center sees episodic patients, many of whom visit once or twice a year, so the first sign of a changed plan is usually a denial weeks after the visit.

That is why the exposure is concentrated in states where a single carrier exited across a large footprint. BCBS Texas alone served 227 counties. Centers in those markets should assume a meaningful share of January Medicare visits involve a patient whose 2026 card is no longer valid. If you operate in these states, our Texas medical billing coverage page and Oklahoma medical billing coverage page list billing partners who already work those payer markets.

Health system ownership matters too. Ten of the 18 exiting plans are tied to health systems, which often steered members toward their own clinics. When those members land in a new plan with a different network, some will use urgent care while they find new primary care, which raises the share of first-time Medicare patients at your front desk in early 2027.

Why Payers Are Leaving and What It Signals

The exits are not one story. Some reflect plans shutting down entirely. According to Becker’s, Providence Health Plan’s exit is part of a wider shutdown, Mass Advantage will close after leaving the market, and Memorial Hermann Health Plan confirmed in July that it would also end its commercial business. Aspirus Health Plan had new Medicare Advantage enrollment suspended by CMS in February after its claims processor, UCare, was taken over by Minnesota regulators.

Other carriers are shrinking rather than leaving. Blue Cross and Blue Shield of Minnesota announced on October 1, 2026 that it is discontinuing most of its Medicare Advantage plans, citing more than $500 million in Medicare losses over the past three years, while launching a new, smaller portfolio for 2027.

For urgent care, the signal is simple: payer churn is now an annual event, not an exception. The same pressure shows up in the commercial changes we covered in September 2026 payer changes for urgent care, and it lands at the same time as the proposed 2027 Medicare conversion factor cut. A center that treats January eligibility as a one-time cleanup will repeat the same denials next year.

The operational takeaway is to build plan changes into your standing workflow. That means a payer matrix that gets updated every fall, a January re-verification rule for every Medicare patient, and a contracting check whenever a new plan starts gaining members in your market.

What Does the January Coverage Gap Mean for Urgent Care Claims?

A patient whose Medicare Advantage plan ends December 31 is automatically covered by Original Medicare on January 1 unless they chose a new plan first. If they pick a new Medicare Advantage plan in January using their special enrollment period, that plan starts February 1, so January urgent care visits bill to Original Medicare, not the new plan.

Under CMS enrollment rules, members of non-renewing plans get a special enrollment period from December 8 through the last day of February, as the Center for Medicare Advocacy explains. Choices made December 8 through December 31 take effect January 1. Choices made later take effect on the first of the following month. That creates five possible coverage paths:

Here is what that looks like in practice. Picture an urgent care in a Texas county where BCBS Texas was a major Medicare Advantage carrier. If the center sees 8 Medicare patients a day and just 2 of them present a terminated card in January, that is about 44 misdirected claims across 22 clinic days. At an illustrative average allowed amount of $120, roughly $5,280 in January revenue sits in denial and rework queues instead of the bank.

Original Medicare allows 12 months from the date of service to file, so most of that money is recoverable. The real cost is rework, delayed cash in peak flu season, and patient statements with the wrong balance. Patients on Original Medicare owe the Part B deductible and 20% coinsurance, not their old plan’s flat urgent care copay.

How Should Urgent Care Centers Prepare for the 2027 Medicare Advantage Exits?

Urgent care centers should prepare by identifying patients on exiting plans now, re-verifying every Medicare patient in real time starting January 2, confirming effective dates on new cards, and routing gap-month claims to Original Medicare. These steps close the gap before it turns into denials:

1. Pull an exposure list. Run a report of 2026 visits billed to the 18 exiting plans so staff recognize those names in January.
2. Re-verify every Medicare patient. Check eligibility in real time through your clearinghouse or the CMS HIPAA Eligibility Transaction System, even for returning patients.
3. Confirm the effective date. Scan the new card front and back, because a plan chosen in January does not start until February 1.
4. Route gap-month claims correctly. Send January claims for patients without active new coverage to your MAC with POS 20 and standard E/M codes.
5. Map each replacement plan. Some Medicare Advantage plans accept S9083 or S9088 and others require standard E/M, so update your payer matrix before the first claim.
6. Check contracts and credentialing. Confirm your providers are in network with the plans gaining members in your market, including HealthSpring in Texas and Oklahoma.
7. Watch eligibility denials weekly. Track CARC 27 (coverage terminated) and CARC 31 (patient not identified as insured) through January and February.

Common Mistakes With Medicare Advantage Plan Exits

The most common issue we see providers run into is trusting the insurance card on file. In urgent care, the card on file is often a year old. For January 2027, assume every Medicare card is suspect until a real-time eligibility response says otherwise. These are the errors that cause the most avoidable rework:

• Billing the new plan for January dates. A plan chosen in January covers services starting February 1, so January claims sent to it will deny.
• Writing off CARC 27 denials. A terminated-coverage denial usually means the claim belongs to Original Medicare, not that the visit is uncollectible.
• Collecting the old copay. Patients defaulted to Original Medicare owe the Part B deductible and 20% coinsurance, not a flat MA copay.
• Assuming HealthSpring equals BCBS Texas. HCSC’s HealthSpring plans are separate products with their own contracts, networks, and billing rules.
• Missing new secondary coverage. Patients leaving a non-renewing plan get guaranteed rights to buy certain Medigap policies, so many will add a secondary payer in early 2027.

That last point is easy to miss. A patient who moves to Original Medicare plus a Medigap policy should produce a crossover claim, where Medicare pays first and the supplement pays the coinsurance. If registration only captures the Medicare card, the coinsurance lands on a patient statement the patient believes is already covered, which creates calls, disputes, and slow collections.

In-House vs. Outsourced Eligibility Work

January already stretches urgent care staff. Respiratory volume peaks, deductibles reset, and every returning patient needs a fresh eligibility check. The 2027 Medicare Advantage exits add a layer on top of that, and federal Medicaid work requirements beginning in 2027 will add more coverage churn for centers with large Medicaid populations.

An in-house team can handle this if it has a real-time eligibility tool, a current payer matrix, and someone who owns denial review every week. Many centers have the tool but not the owner. Front desk staff verify what they can between check-ins, and eligibility denials pile up until someone notices the aging report in March.

In our experience matching providers with billing partners, the urgent care centers that get through January cleanly are the ones whose billing partner treats eligibility as a revenue step. They rerun Medicare eligibility before claims drop, watch CARC 27 and 31 daily, and rebill gap-month claims to the MAC within days instead of weeks.
