Johns Hopkins HealthCare has a new name — Johns Hopkins Health Plans — as it has expanded its business, grown its member base and broadened its geographic footprint across the Mid-Atlantic in recent months. Johns Hopkins Health Plans said it will offer Medicare Advantage plans, an employer group plan for Johns Hopkins Medicine employees, a Medicaid managed care organization and a health plan for active-duty family members, military retirees, and their families in its expanded footprint throughout the Mid-Atlantic region.
