Maryland operates the nation's only all-payer hospital rate-setting system through the Health Services Cost Review Commission (HSCRC) - all payers, including Medicare, Medicaid, commercial, and self-pay, pay the same regulated rates at each facility. This makes Maryland's cash prices more meaningful than in other states, because the discounting common elsewhere is largely prohibited. Johns Hopkins Medicine and University of Maryland Medical System anchor the academic tier.

Why prices vary - and what it means for your coverage

A small number of hospitals (2) report prices above $2,531, including Northwest Hospital Center at $2,695, which drives most of the overall spread - excluding them, most facilities cluster in a much tighter band. Setting matters too: the median outpatient price is $1,029 versus $1,002 inpatient, so where a procedure happens often matters more than which hospital you pick. Setting drives most of the spread here: an ambulatory surgical center (ASC) is usually meaningfully cheaper than a hospital operating room for the same procedure, when your case qualifies.

On top of the facility price, your actual bill depends on your deductible, your out-of-pocket maximum, and whether every provider involved - not just the facility - is in-network.

Why is a sinus surgery so much cheaper at some Maryland hospitals?

Typical prices vary about 1.4× (25th to 70th percentile of negotiated rates) because each hospital sets its own list price, cash discount, and insurer-negotiated rates. In Maryland, the median cash (self-pay) price is $1,074 versus a median negotiated rate of $826 - about 1.3× higher. Asking for the cash price as well as your insurer's negotiated rate is often the single biggest lever on what you pay.

How much will I actually pay out of pocket for a sinus surgery in Maryland?

Your out-of-pocket cost depends on your deductible, coinsurance, out-of-pocket maximum, and whether the facility is in-network - not just the sticker price. If you have not met your deductible, you will typically pay the negotiated rate in full until you do. Use the CostKits cost forecaster to estimate your specific out-of-pocket amount before you go.
