Dayton residents turning 65 should enroll during their 7-month Initial Enrollment Period, which starts 3 months before their 65th birthday month. Missing this window means waiting until the General Enrollment Period (January 1–March 31) and potentially facing a permanent late enrollment penalty on your Part B premium. If you have employer coverage, different rules apply — contact a licensed agent to confirm your exact timeline.
Medicare Advantage (Part C) replaces Original Medicare with an all-in-one plan from a private carrier, typically offering lower premiums but requiring in-network providers in Columbia County. A Medicare Supplement (Medigap) policy works alongside Original Medicare to cover out-of-pocket costs like deductibles and coinsurance, giving you access to any provider nationwide that accepts Medicare. The right choice depends on your health needs, budget, and preferred providers.
