How Medicare Advantage Enrollment Caps and Guidance Could Impact AEP 2027

The Medicare Advantage market is changing. As carriers try to balance growth with sustainability, agents navigating shifting plan availability may have something other than plan suppression and commissions to watch for in 2027: enrollment capacity limits.

New CMS guidance allows certain Medicare Advantage organizations to establish enrollment capacity limits for their plans in their bids. It also expands the plan termination Special Enrollment Period and clarifies Dual Eligible Special Needs Plan (D-SNP) operations.

Here’s what you need to know about the recent updates.

Why Are Medicare Advantage Enrollment Caps Being Allowed?

Hearing that a Medicare Advantage plan can cap enrollment may raise some eyebrows for agents who have experienced carriers stopping commissions or removing plans from enrollment systems.

However, there can be legitimate reasons for a carrier to limit new enrollment.

A plan that experiences unexpectedly high enrollment can put pressure on its systems, staff, provider networks, and ability to serve members.

A plan that experiences unexpectedly high enrollment can put pressure on its systems, staff, provider networks, and ability to serve members. If a carrier grows beyond what it can effectively handle, that can ultimately affect the experience and care of its existing members.

Capping enrollments isn’t new to the Medicare Advantage market, but it happened reactively on a very limited basis. CMS is now allowing certain carriers to apply for enrollment caps proactively, within their June bids, rather than waiting until enrollment growth creates serious operational concerns.

How CMS 2027 MA Enrollment Capacity Limits Work

According to CMS CY27 Medicare Advantage and Part D Enrollment Guidance, “An MA organization that has not established an enrollment capacity limit through the bid submission process under 42 CFR § 422.254(c)(4) or (e)(1) may not restrict enrollment for capacity reasons unless it requests and receives an enrollment capacity limit through the process set forth in 42 CFR § 422.60(b). CMS will consider such requests only if the health and safety of beneficiaries is at risk per 42 CFR § 422.60(b)(3).”

Here’s how Medicare Advantage enrollment caps will work:

• First come, first served: Plans must accept valid enrollment requests in the order they receive them.
• Waitlists: Plans must offer a waitlist to individuals who apply after the capacity limit is reached.
• No cherry-picking: Carriers cannot use enrollment caps to selectively prevent enrollment based on health, demographic, socioeconomic, or other characteristics.
• Minimum capacity: A capacity limit cannot be set below the plan’s enrollment as of June 1, 2026.

How to Navigate Medicare Advantage Enrollment Caps

December 7 remains the Annual Enrollment Period (AEP) deadline, but agents may want to think twice about putting client decisions off until the last minute.

If a Medicare Advantage plan reaches its enrollment capacity during AEP, an otherwise eligible beneficiary may no longer be able to enroll in it.

If a Medicare Advantage plan reaches its enrollment capacity early during AEP, an otherwise eligible beneficiary will no longer be able to enroll in it by any means: broker, Medicare.gov, 1-800-Medicare, direct to carrier, etc. We believe having alternative plans in mind, and starting client conversations early, will become even more important.

Need to find alternate plan options for a client? IntegrityCONNECT allows integrated Medicare Advantage, Part D, life, annuities, and final expense plan quoting, comparison, and enrollment straight from a client’s record.

As of now, it’s unclear if specific carriers’ capacity constraints will be publicly available or what all will happen after a cap is reached (e.g., if the plan will still appear on quote engines or what a waitlisted client’s path to coverage looks like if a spot opens).

We’ll keep you updated on any future carrier and CMS guidance on how Medicare Advantage enrollment caps will work in practice.

Special Enrollment Periods Give Clients More Time After Plan Changes

CMS is also expanding a Special Enrollment Period (SEP) for certain beneficiaries whose Medicare Advantage or Part D plan is terminated or modified.

For applicable situations, the SEP can extend one month after the month of termination.

With continued Medicare Advantage market exits and plan changes, understanding these SEP rules can help agents continue supporting clients after their coverage changes.

How Medicaid Alignment Will Influence D-SNP Enrollment

Beginning in 2027, many D-SNPs affiliated with Medicaid managed care organizations will limit new enrollment to individuals enrolled in, or enrolling in, the affiliated Medicaid plan.

That means Medicare and Medicaid can’t be viewed as completely separate conversations when working with dual-eligible clients. Understanding Medicaid alignment will be increasingly important when evaluating D-SNP options.

Understanding Medicaid alignment will be increasingly important when evaluating D-SNP options.

CMS is also adding new passive enrollment processes for certain integrated D-SNP transitions. Beneficiaries may receive 60-day and 30-day notices before being moved to another integrated plan. Be prepared to answer client questions like “Am I losing my plan?”, “Do I need to do anything?”, or “Was I switched without my permission?”

Agents who can explain these notices quickly will strengthen retention and trust.

What Should Agents Selling Medicare Advantage Plans Do Now?

The 2027 Medicare Advantage landscape isn’t completely settled yet, but agents can start preparing:

• Have backup Medicare Advantage options. A client’s first-choice plan may not always be available.
• Start client conversations early. Don’t wait until the final days of AEP to connect with clients.
• Watch carrier communications. Pay attention to enrollment capacity limits, plan exits, service area changes, and other updates.
• Know your Special Enrollment Periods. They could be especially important for clients affected by plan changes.
• Stay current on D-SNP rules. Medicaid alignment will matter more in 2027.
