Understanding Your Costs
When you receive a bill from MEDSTAR UNION MEMORIAL HOSPITAL, you are typically seeing the hospital's “chargemaster” rate — its published list price for each service. According to CMS data, MEDSTAR UNION MEMORIAL HOSPITAL lists chargemaster rates that average 1.3x the corresponding Medicare reimbursement amount across 91 procedures with publicly available pricing data (Source: CMS IPPS Provider Summary, FY2024).
The median hospital in MD has a chargemaster-to-Medicare ratio of 1.3x, with ratios across the state ranging from 1.1x to 1.3x. At 1.3x, this facility’s average ratio is above the state median. 43 hospitals in MD report pricing data to CMS (Source: CMS IPPS Provider Summary).
What does this actually mean for your bill? Chargemaster rates are rarely what patients pay. If you have insurance, your insurer has negotiated a separate rate — often 40–60% less than the listed price. If you are uninsured, you may be able to negotiate directly with the hospital or request financial assistance. The chargemaster-to-Medicare ratio is a useful reference point for understanding listed pricing, but it does not represent what most patients will owe out of pocket.
MEDSTAR UNION MEMORIAL HOSPITAL is a voluntary non-profit - other acute care hospitals facility with a CMS quality rating of 5/5 stars. Note: CMS quality ratings measure patient outcomes and experience, not pricing. A hospital with high listed prices may provide excellent care, and pricing data alone should not be used to evaluate the quality of a healthcare provider.
