Medicare Advantage enrollees whose doctor drops out of their plan’s network mid-year will not get an easier way to switch plans in 2027 after all. The Centers for Medicare & Medicaid Services had proposed loosening the rules around a special enrollment period tied to network changes, but left that proposal out of the final rule it issued for the coming plan year. The existing, narrower version of that special enrollment period remains in place instead, meaning most members whose doctor leaves a network will still have to wait for the standard fall enrollment window to switch plans.
The Network-Change Exception That Already Exists
Medicare has long allowed a case-by-case special enrollment period for people who experience a “significant change” in their plan’s provider network, distinct from the annual window everyone else uses. Under this existing option, a member can join a different Medicare Advantage or Medicare drug plan, switch plans, or drop Medicare Advantage coverage and return to Original Medicare, but only after Medicare or the plan determines the network change actually qualifies as significant, according to Medicare.gov’s own list of special enrollment periods. That evaluation happens case by case, and the enrollee generally gets two months to act once the special enrollment period is granted.
The “significant” qualifier has always been the sticking point. A single physician leaving a large network, even one a patient has seen for years, does not automatically meet that bar, since Medicare and plans typically look at how much of the overall network changed rather than the impact on any one member’s care.

What CMS Proposed To Change, And Why It Stalled
In its proposed rule for the coming plan year, CMS floated removing the word “significant” from that standard altogether, which would have let an enrollee qualify for the special enrollment period whenever any provider they had seen within a specified recent period left the network, regardless of how small that individual network change was in the context of the plan as a whole. The change was aimed squarely at the scenario driving most member complaints: one trusted doctor disappearing from a network, even when the rest of the plan’s provider list barely moved.
CMS ultimately left that provision out of the Contract Year 2027 Medicare Advantage and Part D final rule it issued on April 2, 2026, finalizing a long list of other Star Ratings, Part D and supplemental-benefit provisions while staying silent on the network-change proposal. Health policy analysts who track the rulemaking process closely noted that CMS did not explain why the provision was dropped or respond to the comments it received on the idea, according to an analysis from McDermott+’s regulatory affairs team, a silence that leaves the door open for CMS to revisit the idea in a future rule rather than having rejected it outright.
What A Member Can Still Do If A Doctor Leaves Mid-Year
Without the broader special enrollment period, a member whose doctor exits a Medicare Advantage network mid-year generally has three practical paths. The member can stay in the plan and find a new in-network doctor, wait for the annual Medicare Open Enrollment Period that runs October 15 through December 7 to switch for the following year, or ask Medicare directly whether the specific network change meets the existing “significant” threshold, since that determination is still made on a case-by-case basis rather than automatically. Medicare’s rules also leave room for other exceptional circumstances to be evaluated individually, so a member who believes their situation is unusual enough can still call to ask, even without a guarantee of qualifying.
The distinction matters most for people mid-treatment with a specialist, since finding a new in-network provider for an ongoing course of care carries real disruption that a plan’s aggregate network statistics do not capture. Until CMS revisits the standard, that disruption remains something enrollees have to manage largely on their own, either by confirming a preferred doctor’s network status before enrolling or by accepting the two-month gap between when a network change happens and when the next full enrollment opportunity arrives.
Other Beneficiary Provisions CMS Did Finalize
The network-change proposal was not the only item CMS left on the table in the CY2027 final rule, but it stood out because most of the other decisions moved in the industry’s favor rather than the beneficiary’s. CMS also chose not to move forward with a Health Equity Index that would have rewarded plans for improving quality among low-income and disabled enrollees specifically, instead keeping an existing reward factor that credits plans for improving performance across their entire membership. The agency did finalize new rules requiring plans that hand out supplemental benefits through debit cards, covering things like groceries, over-the-counter items or transportation, to verify in real time that a purchase actually qualifies as a covered benefit before the card can be used, closing a gap that had allowed misuse of those cards on ineligible purchases.
Taken together, the rule illustrates a pattern industry watchers have flagged repeatedly this cycle: CMS is willing to grant plans more flexibility and less administrative burden, including removing several health-equity-related reporting requirements entirely, while beneficiary-facing protections like the network-change special enrollment period move more slowly, if they move at all. Nothing in the final rule prevents CMS from finalizing the network-change expansion in a later rulemaking cycle, since the agency generally has up to three years from a proposal to act on it, but no timeline for revisiting the idea has been announced.
