Financial assistance

Nonprofit hospital: it must offer free or discounted care to patients who qualify. How to apply

Ascension Seton Williamson is a nonprofit hospital in the CMS register. Under section 501(r) of the federal tax code it must have a written Financial Assistance Policy with a free application, publish both on its website, and charge patients who qualify no more than the amounts generally billed to insured patients for emergency and other medically necessary care. Who qualifies depends on household income; the policy states the limits.

You can apply up to 240 days after the first bill. Before collection actions such as credit reporting or a lawsuit, the hospital must tell you about the policy and wait at least 120 days after that bill. Ask the billing office for the policy and the application before you pay, or search the hospital's website for “financial assistance”. Letters you can copy.

Procedure The service, with its billing code (CPT or HCPCS) and, in small type, the line exactly as the hospital wrote it in its price file. More
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
Insurers pay The lowest and highest rates this hospital has agreed with insurance plans for the same item, from its price file. If the cash price is below what your plan pays and you have not met your deductible, paying cash can cost you less. More
Against the state median This hospital's cash price compared with the median cash price of hospitals in the state for the same code. Shown when at least three hospitals in the state price it.
Off list How much lower the cash price is than the list price.
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
At or below Medicare This cash price is at or below what Medicare pays a hospital for the same service, which is unusually low. It is what the hospital's file says; confirm it and what it includes before booking. More
Check the item The description in the hospital file looks like a supply or device (a catheter, a brace, an implant), not this procedure. The hospital may have filed it under the wrong code: ask before relying on this price.
