QUICK ANSWER
- What do the 2027 Medicare Advantage plan terminations mean for urology? As of October 2026, the 2027 Medicare Advantage plan terminations refer to 3.1 million Medicare Advantage drug plan enrollees whose plans end December 31, 2026, according to a KFF analysis of CMS data published October 27. For urology practices, that means a January wave of new payers, voided authorizations, and eligibility denials across a heavily Medicare-age patient panel.
- Who is affected: Humana, UnitedHealth Group, CVS Health, and a Minnesota Blue Cross seller account for half of the enrollees losing individual Medicare Advantage drug plans.
- What changes January 1: Patients who do not choose a new plan move to traditional Medicare, and authorizations issued by the old plan do not follow them.
- What to do now: Re-verify coverage for every Medicare patient scheduled for a January procedure before the claim goes out, not after it denies.
What KFF Found in the 2027 Plan Data
On October 27, 2026, KFF published an analysis of CMS landscape, crosswalk, and enrollment files titled More Than 4 Million Medicare Beneficiaries Will Have Their Medicare Advantage or Stand-Alone Prescription Drug Plan Terminated at the End of 2026. The headline number is 4.3 million beneficiaries, split between Medicare Advantage drug plans and stand-alone Part D plans. Another 1.4 million Medicare Advantage enrollees are in plans being consolidated into a different plan from the same insurer.
| Group | Enrollees Affected | What Happens on January 1, 2027 |
| Individual MA drug plans terminated | About 2.8 million | Enroll in a new MA plan or default to traditional Medicare |
| Special needs plans terminated | About 300,000 | Enroll in a new plan; duals have added switch options |
| Stand-alone Part D plans terminated | About 1.2 million | Choose a new Part D plan or lose drug coverage |
| MA plans consolidated | About 1.4 million | Moved automatically to the insurer’s other plan |
The 2.8 million individual Medicare Advantage enrollees losing their plans equal 14% of everyone in general-enrollment Medicare Advantage drug plans, close to the 13% affected heading into 2026. Four parent organizations account for half of them: Humana with about 530,000 enrollees, UnitedHealth Group with about 367,000, CVS Health with about 254,000, and Aware Integrated, which sold Blue Cross branded plans in Minnesota, with about 249,000.
On the Part D side, about 950,000 of the 1.2 million affected enrollees are in CVS Health’s SilverScript Choice plan, which is ending in 13 regions, and about 190,000 are in HealthSpring Extra Rx, ending in 16 regions. KFF notes that the average beneficiary will have 28 Medicare Advantage drug plans and 9 stand-alone Part D plans to choose from for 2027.
Which Urology Patients Will Be Affected?
The urology patients most affected are Medicare Advantage members in terminating Humana, UnitedHealthcare, Aetna, and Minnesota Blue Cross plans, plus traditional Medicare patients on SilverScript Choice or HealthSpring Extra Rx drug plans. Patients with BPH, kidney stones, prostate cancer, and overactive bladder are at the highest risk because they visit often.
Urology panels skew older than almost any outpatient specialty, so a 14% termination rate in individual Medicare Advantage plans lands harder here than in most practices. A patient in active treatment is the one who feels it first: a man on surveillance for prostate cancer with quarterly PSA checks, a stone former waiting on a staged ureteroscopy, or an incontinence patient partway through a device workup.
Drug coverage matters too. Many urology patients rely on Part D for overactive bladder medications and oral prostate cancer therapies. If their stand-alone drug plan ends and they do not choose a replacement, the next prescription fills can stall, and your staff will field the calls and the new prior authorization requests.
Geography concentrates the impact. The Minnesota Blue Cross branded plans sold by Aware Integrated account for about 249,000 terminated enrollees on their own, so Minnesota urology groups should expect an unusually heavy January. Practices there can compare local billing support through the Billing Service Quotes Minnesota coverage page.
One question we hear constantly from practice managers is whether consolidated plans count. They do not terminate, but the patient still lands in a different plan with potentially different networks and authorization rules.
Why Insurers Are Exiting Medicare Advantage Plans
KFF’s analysis places the terminations inside a broader pullback. Several insurers announced before the October 15 start of open enrollment that they would reduce Medicare Advantage offerings for 2027. In the Part D market, the administration ended the Part D Premium Stabilization Demonstration one year early, which KFF ties to uncertainty about premiums and plan availability for stand-alone drug plans. For practices, the practical effect is the same either way: more patients changing coverage on the same date.
A structural change is also reshaping special needs plans. Starting in January 2027, an insurer that offers a dual eligible special needs plan and an affiliated Medicaid managed care plan in the same county may generally offer only one D-SNP for full-benefit dual-eligible individuals. KFF reports that insurers made a large number of D-SNP changes to comply, which is a major reason about 900,000 special needs plan members are being consolidated.
The signal for urology is that January churn is no longer an occasional event. Terminations hit 13% of individual Medicare Advantage drug plan enrollees heading into 2026 and 14% heading into 2027. Combined with the Medicare rate pressure described in our 2027 Medicare fee schedule breakdown for urology, payer churn has become a recurring cost that practices need to plan for every fall.
In our experience matching providers with billing partners, practices that treat January eligibility as a project, with its own owner and deadline, avoid most of the denials that practices treating it as routine front desk work absorb.
What Will January 2027 Cost a Urology Practice?
January 2027 will cost an unprepared urology practice through claims billed to plans that no longer exist, procedures performed under authorizations that lapsed on December 31, and delayed payment while coverage is corrected. Most of the cost is cash delay, but authorization denials can become permanent write-offs.
Consider an illustrative scenario. A practice schedules 40 January procedures for patients whose Medicare Advantage plans terminated, including diagnostic cystoscopies like CPT 52000, TURPs, and staged stone procedures. If those claims carry an average allowed amount of $350 and go to the old payer, about $14,000 is stuck in denial and rework. If even a quarter of those cases also lacked a valid new authorization, roughly $3,500 could become unrecoverable. The figures are hypothetical, but the pattern repeats every January in practices without a rollover plan.
Patients who default to traditional Medicare are not automatically in the clear. Practices in Arizona, New Jersey, Ohio, Oklahoma, Texas, and Washington still face prior authorization for selected services under the WISeR model for urology, including incontinence control devices, sacral nerve stimulation for urinary incontinence, and treatment of impotence.
Secondary coverage adds another layer. Patients pushed into traditional Medicare qualify for a Medigap special enrollment period with guaranteed issue rights, so a supplemental policy may appear in January that was never on file. Front desk time is the hidden cost: every misbilled January claim means a patient call, a new eligibility check, a corrected claim, and often a call to the new plan.
What Should Urology Practices Do Before January 1, 2027?
Urology practices should identify Medicare Advantage patients in terminating plans now, re-verify coverage for every January appointment, and secure new authorizations before December 31 rollover. The goal is to submit January claims to the right payer the first time instead of discovering changes through denials.
- Pull a payer report. List every active patient covered by a terminating Humana, UnitedHealthcare, Aetna, or Minnesota Blue Cross plan.
- Contact high-risk patients. Remind patients in active treatment to choose new coverage before open enrollment ends December 7, 2026.
- Re-verify January schedules. Run real-time eligibility on every Medicare patient booked for the first six weeks of 2027.
- Restart prior authorizations. Submit new requests to the incoming plan for any procedure scheduled after January 1.
- Update secondary coverage. Capture new Medigap or Medicaid information at the first January visit.
- Confirm network status. Check that your practice and each clinician are in network with the plans patients are choosing.
- Track denials by payer. Flag eligibility and authorization denials weekly through March so patterns surface early.
Assign each step an owner and a date. A simple tracker listing the patient, old plan, new plan, authorization status, and next appointment keeps the work visible. Start with patients who have procedures, device trials, or recurring injections on the books, since those visits carry the largest allowed amounts and the strictest authorization rules. Then work outward to routine follow-ups, where a missed eligibility check usually means a delayed claim rather than a lost one.
January eligibility checks, new authorizations, and payer changes all land on the same small team. In our experience, practices that hand this work to a urology-focused billing partner keep cash moving through the rollover.

Common Mistakes With Plan Terminations
The first mistake is assuming an authorization travels with the patient. It does not. An approval issued by a terminated plan has no value once that plan ends, so a TURP or ureteroscopy scheduled for January needs a fresh request to whoever covers the patient on the date of service.
The second mistake is treating consolidation like business as usual. About 1.4 million enrollees are being moved automatically to another plan from the same insurer. The insurer name on the card may look familiar, but the plan ID, network, and utilization rules can all change. Treat every consolidated plan as new until you have confirmed its 2027 details.
The third mistake is relying on what the patient says. Many patients will not realize their plan ended until a claim denies, and some will enroll in a new plan during the Medicare Advantage open enrollment period that runs January 1 through March 31, changing coverage a second time. Ask every Medicare patient at check-in whether their plan changed, even when the card looks the same.
The fourth mistake is ignoring payer-specific authorization changes that take effect at the same time. Rules shift every year, as our coverage of the UnitedHealthcare prior authorization changes for urology shows, so verify requirements with the new plan rather than reusing last year’s checklist.
The most common issue we see providers run into is working January denials one claim at a time instead of fixing eligibility at intake, where the error starts.
In-House vs. Outsourced Eligibility Work
Small practices can manage the rollover in-house if one person owns it, the payer report is accurate, and staff have time to call patients before December 7. The math changes for larger groups. A practice with several thousand Medicare Advantage patients may have hundreds affected, and every one of them needs eligibility, authorization, and secondary coverage checked during the same weeks staff are closing out year-end claims.
Prior authorization is also getting more technical. Electronic prior authorization requirements are expanding, as explained in our guide to CMS electronic prior authorization changes for 2027, and billing teams that already work inside payer portals and electronic workflows absorb plan changes faster.

Requests are reviewed by a real person, including Tim Daniels, Director of Strategic Accounts at Billing Service Quotes, who helps urology practices connect with billing companies that understand eligibility, authorization, and revenue cycle work. Many companies in our network also support credentialing and contracting, which helps when a practice needs to join the networks patients are moving into.
Ask any prospective billing company how it handled the 2026 rollover, how quickly it re-verifies eligibility in January, and how it tracks authorizations when a patient changes plans mid-treatment. Practices often come to us after a January backlog spilled into spring, and the answers to those questions predict whether it happens again.
Frequently Asked Questions
When do the 2027 Medicare Advantage plan terminations take effect?
The terminated plans end December 31, 2026. Beginning January 1, 2027, affected patients are covered by whatever plan they chose during open enrollment, which runs October 15 through December 7, 2026, or by traditional Medicare if they did not choose a new Medicare Advantage plan.
Do prior authorizations transfer when a Medicare Advantage plan terminates?
No. An authorization issued by a terminated plan does not carry over to the patient’s new coverage. Any procedure scheduled on or after January 1, 2027 needs a new authorization from the plan covering the patient on the date of service, if that plan requires one.
What happens if a patient does not choose a new plan?
According to KFF, Medicare Advantage drug plan enrollees in terminating plans who do not enroll in another Medicare Advantage plan are switched automatically to traditional Medicare. They also qualify for a Medigap special enrollment period with guaranteed issue rights for supplemental coverage.
Which insurers are terminating the most Medicare Advantage plans?
KFF found that Humana, UnitedHealth Group, CVS Health, and Aware Integrated, which sold Blue Cross branded plans in Minnesota, account for half of the individual Medicare Advantage drug plan enrollees losing coverage. Humana alone accounts for about 530,000 affected enrollees, or 19% of the total.
Can patients change plans again after January 1, 2027?
Yes. Medicare Advantage enrollees can switch to another Medicare Advantage plan or to traditional Medicare during the Medicare Advantage open enrollment period, January 1 through March 31. That means some patients’ coverage may change twice early in 2027, so practices should re-verify at every visit.
