Maryland's health insurance exchange has only four carriers for 2026: UnitedHealthcare, Kaiser Permanente, Blue Cross Blue Shield and Wellpoint Maryland, Inc. Three of them sell only HMO plans. Blue Cross Blue Shield changes the carrier choice calculus here compared to states with eight or 10 competing insurers.
Maryland operates its own marketplace, Maryland Health Connection, with an open enrollment deadline of January 15 for 2026 coverage. When we reviewed 2026 plan data across all metal tiers for a 40-year-old, the spread between cheapest and most expensive Silver-tier HMO was $58 per month: $411 at UnitedHealthcare versus $469 at Blue Cross Blue Shield. That gap is real but narrower than most states, so network structure and cost-sharing terms matter as much as monthly premium in this market.
