HealthyMarks Medicare was founded in 2016 by Keaton Marks after he trained as a health insurance specialist at KingBenefits in Carlsbad, and now operates as a husband-and-wife Mission Hills brokerage with Alexa Marks leading Medicare client intake. The agency holds carrier appointments with Blue Shield of California, Anthem, Kaiser Permanente, SCAN Health Plan, UnitedHealthcare, and Humana, enrolling clients in Supplement Plans that preserve access to Medicare-accepting primary care physicians such as George Papas, MD. Advantage Plan consultations walk through network restrictions across Scripps, Sharp HealthCare, and UC San Diego Health, including the UCSD Medicare Advantage acceptance changes taking effect in 2025. Part D prescription drug plan comparisons run against the CMS Plan Finder formulary data during the Annual Enrollment Period from October 15 through December 7. Supplement Plan F, Plan G, and Plan N quotes factor in the specialist referral patterns clients will need for orthopedic care, which San Diego Orthopaedic Associates Medical Group, Inc. handles once joint replacement or spine surgery enters the picture. The most intricate cases the office works are beneficiaries losing employer group coverage mid-year who must coordinate COBRA, a Special Enrollment Period, Part B late-enrollment penalty avoidance, and Medigap guaranteed-issue rights in a single transition window.
