CA 19-9 test cost in Maryland

In Maryland, 15 hospitals publish a cash price for CA 19-9 blood test (tumor marker): from $50.37 to $193.60, with a median of $94.85. The lowest price is at Greater Baltimore Medical Center (Towson). The highest price is 3.8× the lowest.

The median here, $94.85, is 3% below the US median of $98.00.
That is 4.6× Medicare's 2026 national rate for the same service ($20.81).
Maryland ranks 20th of 51 states by median, cheapest first.
2 of 15 hospitals list a cash price equal to their full list price, with no self-pay discount.

Why Maryland prices look low: Maryland is the only state where a commission (the HSCRC) sets hospital rates for every payer, so its hospitals publish prices far below the rest of the country. A separate physician fee may still apply.

Maryland law (Health-General §19-214.1) requires hospitals to give free medically necessary care to patients with family income at or below 200% of the federal poverty level and to cut the bill by 75% up to 250% and 60% up to 300%. With medical debt above 25% of family income in a year, discounts reach up to 500%. Immigration status does not count. Ask the hospital for its financial assistance application. Other states' laws.

Hospital The hospital that published the price, its city and the line exactly as written in its price file.

Cash price The hospital's own price for a patient paying without insurance (“discounted cash” in its price file). Hospitals must publish it under federal law, 45 CFR 180.50. Call to confirm it before booking. More

List price The hospital's full chargemaster price (“gross charge”) before any discount. Almost nobody pays it; the gap to the cash price shows what the self-pay discount is worth. More

File date When the hospital last updated its price file, as the file says itself. A dash means the file gives no date.

No cash discount This line's cash price equals the hospital's full list price. Many hospitals still reduce bills for uninsured patients: ask the billing office for its self-pay discount in writing. More
