Does the current Medicare Advantage landscape make you feel confident about your future healthcare coverage?
UnitedHealthcare and Humana will discontinue specific Medicare Advantage plans for the 2027 coverage year, a change affecting nearly one million members. The shifts take effect January 1, 2027, forcing affected policyholders to select new coverage options.
Why it matters
The contraction of service areas and plan offerings reflects ongoing shifts in the Medicare Advantage market as providers adjust their participation strategies. Operators in healthcare and senior services should prepare for a period of patient churn and administrative complexity as coverage transitions begin.
Humana will discontinue plans for 600,000 members, while UnitedHealthcare changes affect 390,000 policyholders. Nationally, the projected average monthly premium for Medicare Advantage is $12.00 for 2027, down from $14.37 in 2026.
The players
UnitedHealthcare
A division of UnitedHealth Group, this major national insurer is a dominant provider of Medicare Advantage and commercial health plans.
Humana
A major health insurance company that maintains a significant portion of its business in government-sponsored health programs.
The details
Affected members must either enroll in an alternative Medicare Advantage plan or transition to Original Medicare to ensure continuity of coverage. UnitedHealthcare sent notification of these changes to members on October 2, 2026. For those whose plans are not renewed, the government provides a special enrollment period that begins December 8, 2026, and extends through February 28, 2027.
Timeline
Oct. 2, 2026: Notices were sent to affected UnitedHealthcare members.
Oct. 15, 2026: The Medicare open enrollment period began.
Dec. 7, 2026: The standard Medicare open enrollment period ends.
Jan. 1, 2027: Plan closures and service-area reductions take effect.
Feb. 28, 2027: The special enrollment period for affected members ends.
Market Landscape
These plan exits represent a significant contraction of offerings within the highly regulated Medicare Advantage market. The changes follow the established timeline set by the Medicare Advantage open enrollment period.
Healthcare providers should monitor patient transition timelines and clarify coverage options for patients impacted by these insurer exits. Operators should verify patient eligibility using the upcoming December special enrollment window.
The takeaway
Operators must track patient transitions closely through the end of the special enrollment period on February 28, 2027. Reviewing billing systems now will help mitigate administrative friction when coverage updates take effect at the start of the year.
