Naomi Foster researches and writes the Medigap and Medicare coverage on MedigapExplained for Encore Editorial. Her work focuses on the parts of Medicare enrollment that cause the most confusion in practice: the six-month window that never reopens, the real difference between plan letters once you run the numbers, and the paperwork that shows up after enrollment with little explanation attached. Every figure she publishes is checked against CMS releases and Medicare.gov before it goes live, and both are cited by name and date on the page.
