Capped plans can close mid-AEP: what agents need to know about 2027 enrollment limits

For 2027, some Medicare Advantage plans can stop taking new members in the middle of the Annual Enrollment Period. Once a capped plan fills, it closes, and there is no public countdown telling you how close it is. If a client’s best option is a capped plan, enroll early.

What’s happening

CMS’s 2027 enrollment and disenrollment guidance, released August 25, 2026, spells out how enrollment capacity limits work. A Medicare Advantage organization can set a capacity limit for one or more plans in its annual bid. A plan with a limit “must accept all valid enrollments in the order they are received until the capacity limit is reached.” After that, it “must remain closed to all prospective enrollees until space becomes available through natural attrition.”

The guidance applies to every enrollment with an effective date on or after January 1, 2027, so it covers applications you write during this AEP.

Becker’s reviewed CMS’s 2027 data and found 65 capped plans from 15 parent organizations in 11 states. The caps range from 410 to 56,345 members.

How a closure works

• The cap belongs to the plan. Caps are set plan by plan in the bid. A separate CMS process lets a plan limit enrollment in all or part of its service area later in the year, but CMS considers that “only if the health and safety of beneficiaries is at risk.” A plan that did not set a cap in its bid cannot close for capacity without that approval.
• The order applications arrive in matters. If a plan hits its cap during a day’s processing, it must still process every application it received before the cap was reached. Only applications received after the plan is full are denied.
• Denials take time to arrive. The plan must send a denial notice that explains the reason within 10 calendar days. CMS’s 2027 model denial notice adds reasons for capacity limits and closed plans, Tech Savvy Insurance reports. An application written in early December could be denied after AEP has ended.
• Current members are not removed. Plans cannot disenroll current members because of a cap.
• No advance warning is required. CMS’s guidance does not require advance public notice of a closure. A plan can look fully open one day and be closed the next, Goodsurance notes.
• Standalone Part D plans are not covered. The guidance gives capacity-limit authority to Medicare Advantage plans, not to standalone prescription drug plans.

Some carriers publish status pages. HealthPartners lists each capped 2027 plan by contract number, county service area and enrollment status. As of its October 1 update, every plan was open. HealthPartners also warns that waiting could leave fewer options “because plans may have reached their enrollment capacity limits and closed to new enrollments.”
