CareSource Medicare plans in Indiana for 2026.

CareSource in Indiana

CareSource is nonprofit Medicare carrier with strong Indiana presence. In Indiana specifically, CareSource's Medicare offerings include Medicare Advantage (HMO and PPO), standalone Part D prescription drug plans, and (for many of these carriers) Medicare Supplement (Medigap) policies that pair with Original Medicare.

Indiana has approximately ~1,200,000 Medicare beneficiaries. About half are enrolled in Medicare Advantage; the other half use Original Medicare, often with a Medigap supplement and standalone Part D plan. CareSource competes for both segments in Indiana.

CareSource Medicare plan types in Indiana

Medicare Advantage (Part C): CareSource offers HMO and PPO Medicare Advantage plans in most Indiana counties. Many include $0 monthly premium plus extras like dental, vision, hearing, OTC allowances, and (in select plans) transportation to medical appointments. Plan availability and benefits vary by county — major metros generally have 5-15 CareSource options; smaller counties may have 2-5.

Medicare Part D (prescription drug coverage): CareSource sells standalone Part D plans in Indiana that pair with Original Medicare. The new 2026 Part D $2,000 out-of-pocket cap protects against catastrophic drug costs regardless of carrier. Specific formulary placement of your medications matters more than the carrier name — we verify your prescriptions before recommending any plan.

Medicare Supplement (Medigap): CareSource sells Medigap plans (federal letter Plans A, B, D, G, K, L, M, N) in Indiana. Plans are standardized by federal law — Plan G from CareSource provides identical coverage to Plan G from any other carrier. Pricing is what differs. CareSource's Medigap rates may be higher or lower than competitors in your specific ZIP code, age, gender, and tobacco status.

Major Indiana hospital systems and CareSource access

Major Indiana hospital systems include IU Health Methodist, Eskenazi Health, Riley Children's, St. Vincent (Ascension), Lutheran Hospital + Parkview (Fort Wayne). Whether your specific CareSource plan accepts these systems depends on the plan and the year. Hospital networks change annually as carriers renegotiate contracts.

Before you enroll: Always verify your specific doctors, hospitals, and prescriptions against the exact CareSource plan you're considering. We do this for free as part of our consultation.

Indiana Medigap rules that apply to CareSource

Indiana allows medical underwriting on Medigap outside your initial 6-month Open Enrollment window. Standard rates and switching rules apply.

This applies to CareSource Medigap as well as competitors. We use these state-specific protections strategically — for example, helping members re-shop CareSource Medigap during their Indiana switching window for potential savings.

Should you choose CareSource or another carrier in Indiana?
