Why New York State Rules Matter for Humana Coverage

New York's insurance regulations create important protections for patients seeking specialty medications like Xembify, even within federal Medicare programs. While Humana Medicare Advantage follows federal Medicare appeals processes, New York state laws still influence coverage in several key ways:

  • Continuity of care protections help maintain Xembify therapy during plan transitions
  • Step therapy reform laws (effective January 2026) limit how many medications you must try before accessing Xembify
  • External appeal rights apply to state-regulated commercial plans (though not Medicare Advantage)
  • Consumer assistance programs provide free help navigating denials and appeals

Understanding how these state and federal rules interact helps you build the strongest possible case for coverage.
