Medical bill code guide
CPT Code Lookup
A CPT code is a five-digit label used to describe a medical service or procedure. Start with the code, then match it to the itemized bill, EOB, and records from the visit.
Browse 234 codes below. Each page gives you plain questions to ask. It does not guess a fair price or decide that a charge is wrong.
A code alone cannot tell you the right price
Hospital price checks need the hospital or location, code or service, exact insurer and plan, source file, and file date. Gross charge, discounted cash price, payer-negotiated amount, and allowed amount are different values. Keep them separate.
