Imagine arriving at your longtime doctor’s office in January, only to discover that your Medicare Advantage plan no longer considers that physician in-network. The appointment you’ve been waiting months for could suddenly become more expensive, or you might need to find an entirely new doctor. Unfortunately, this is a possibility many Medicare beneficiaries overlook when reviewing their coverage each fall.
With Medicare’s annual Open Enrollment Period underway through December 7, 2026, now is the time to check your Medicare network for 2027 before making coverage decisions. Medicare Advantage plans can change their participating doctors, specialists, hospitals, and other healthcare providers from year to year. Even if you’re happy with your current plan, there’s no guarantee every provider you use will remain in its network next January. Here’s what to check before the enrollment deadline arrives.
