Itemized Bill

An itemized bill is the detailed, line-by-line breakdown of every charge on a medical bill — every medication administered, every supply used, every service rendered, each with its CPT or revenue code and its charge. What most patients receive by default is a summary bill showing a few grouped totals; the itemized bill is the underlying detail you have to specifically request.

The reason to always ask for it: error rates on hospital bills run somewhere between 30 and 80 percent depending on which study you read, and the errors are almost always in the hospital's favor. I've seen bills with charges for procedures that never happened, medications billed twice, ICU day rates on days the patient was on a regular floor, and supplies billed at 20 times reasonable prices. Federal law (and most state laws) require providers to give patients an itemized bill on request, at no charge. Some hospitals will send it same-day; some drag their feet — a written request citing the state's medical records law usually breaks the logjam.

The takeaway: for any hospital bill over $500, request the itemized bill before paying anything. Compare each line to what you actually experienced during the stay. Errors are common and correctable, but only if you catch them before the payment or the appeal window closes.
