Snowbirds Beware: Medicare Advantage Plans Enforce Six-Month Absence Limits

A Medicare Advantage plan will terminate coverage for a 74-year-old member who spends more than six consecutive months outside the plan's service area, even if the member maintains a primary residence in the home state and the plan offers out-of-network coverage. A November 1 departure for Arizona creates a six-month expiration in May, meaning a June 15 return is too late to prevent disenrollment on June 1. Members losing Advantage coverage trigger a special enrollment period and may qualify for guaranteed-issue Medigap coverage, though prescription drug coverage ends immediately and must be replaced separately.

Medicare Advantage plans distinguish between two separate coverage questions that many retirees conflate. While a plan's PPO benefits may cover out-of-network care in other states, federal residency rules operate independently—requiring disenrollment if a member remains outside the service area beyond six months. Plans can obtain approved traveler benefits extending this period to 12 months, though these vary by region and provider network. Without such programs, the clock begins on the departure date regardless of when actual medical services occur.

Members who lose Advantage coverage due to extended absence gain access to special enrollment periods, potentially triggering guaranteed-issue Medigap eligibility. However, prescription drug coverage terminates immediately upon disenrollment, requiring separate replacement through standalone Part D plans. This gap can create coverage lapses if members don't act quickly during the transition.
