The national average price.
State prices from RAND's hospital price study — how much your state's hospitals charge private insurers relative to Medicare. This is a statewide price level, not a per-procedure state price. Maryland isn't shown: it sets hospital rates for all payers, so the comparison doesn't apply there.
This is an estimate, not a bill. It applies published average deductibles and a 20% coinsurance
(KFF's measured average for a hospital admission) to a national average price. Your actual plan, hospital and
diagnosis will move this number. Not medical or financial advice.
