2026 AEP Cycle Watch AEP Cycle Watch

What this series will cover

The AEP Cycle Watch series covers regulatory and policy developments that change something a Medicare beneficiary needs to know or do. That means CMS rate announcements for the coming year, changes to Medicare Advantage marketing rules, final rulemakings that affect enrollment periods or cost-sharing structures, IRMAA bracket adjustments, court decisions that overturn or restore CMS rules, and state-level changes to guaranteed-issue protections. It does not cover every Medicare news item — only the ones that change a beneficiary decision or a current beneficiary’s bill. The signal-to-noise standard is high by design.

What we are watching right now

Four items are on the watch list for the remainder of 2026:

• CMS announcement of 2027 Part B premium and deductible — typically released in late October, coinciding with the close of AEP. This is the figure that will appear in Social Security deductions beginning January 2027.
• 2027 Medicare Advantage star ratings — also released in October. Star ratings affect plan availability, bonus payments, and the out-of-pocket maximums plans can charge. Plans that fall below three stars two years running face discontinuation.
• Final ruling on Medicare Advantage broker compensation rules — CMS’s 2024 rule attempting to limit administrative fees paid to marketing middlemen was struck down by federal court in August 2025. Whether CMS reissues a revised rule, pursues appeal, or allows the current compensation structure to stand will affect how MA plans are marketed and which plans brokers are incentivized to recommend.
• State-level guaranteed-issue protection changes — the birthday-rule expansion has added states each year since California adopted the model in 2020. Any additional state adoptions in 2026 would materially change the Medigap access picture for beneficiaries in those states.

Why this matters

Medicare’s rules don’t change often — but when they change, they often change quietly. Most beneficiaries find out about a premium increase from an adjusted Social Security deposit. Most find out about a plan network change from a letter they didn’t read closely in October. The point of this series is to surface the change ahead of the consequence — far enough ahead that the information is still actionable. A rate announcement in late October is useful. The same information delivered in January, after AEP has closed, is not.

How updates work

Each substantive update in this series will include a structured summary at the top: what changed, who it affects, when it takes effect, and what to do (or decide not to do). Sources are always linked. Where the update requires a decision before a hard deadline — like an enrollment-window change or a plan termination notice — that urgency is flagged at the top of the post, not buried in the prose. The goal is that a reader who arrives with three minutes should leave knowing whether the update applies to them and what their options are.
