Billing codes

The codes on your bill, explained

An itemized bill is a list of codes. Each one is a claim about what was done, and each one can be checked. These are the codes that show up most, what they mean in plain English, what tends to be wrong with them, and what to ask.

Medicare figures are national averages of what Medicare accepted for the physician or practitioner claim, from the Centers for Medicare & Medicaid Services (2024 data). Hospital revenue codes have no physician figure. Code names are mediloop's own summaries, not the official CPT descriptors, which belong to the American Medical Association.
