What does this code mean?
Hospital bills are written in codes for a reason — most patients give up before they decode them. Look up any CPT, HCPCS, or revenue code in seconds.

What's on a hospital bill
- Revenue (REV) codes — 4 digits. Tell you which hospital department billed (ER, pharmacy, lab).
- CPT codes — 5 digits. The actual procedure or service performed.
- HCPCS codes — letter + 4 digits. Drugs, supplies, and equipment.
Always request an itemized statement (not the summary bill) so you can see every line code.
Search by code, category, or keyword.
Try 0450, 99285, or MRI.
Before you act on this — verify with your insurer or provider
These explanations are educational only. They are not medical, billing, or legal advice and should never replace the official records from your hospital, doctor, or insurance plan. Codes can be modified by suffixes, bundled with other services, or applied differently depending on your specific plan.
Call your provider's billing office
Ask for an itemized statement (the CMS-1500 or UB-04 form) — they're legally required to provide one. Confirm:
- • The exact code billed and its modifiers (e.g.
-25,-59) - • The diagnosis code (ICD-10) tied to it
- • Whether the service was bundled or billed separately
Call the number on your insurance card
Request the Explanation of Benefits (EOB) for that claim. Ask:
- • Was this code covered under my plan?
- • What was the contracted (allowed) amount?
- • How much did I actually owe after the network discount?
Why the same code can cost wildly different amounts
A code identifies what was done — not what it costs. The price you see depends on a stack of factors that have nothing to do with the procedure itself:
- Negotiated rates — every insurer negotiates a different "allowed amount" with each hospital. Cash prices are different again.
- Facility fees — the same CPT done in a hospital outpatient department can cost 2–5× more than at a freestanding clinic.
- In- vs. out-of-network — out-of-network providers can balance-bill you for the gap between charge and allowed amount.
- Modifiers & bundling — a
-26or-TCmodifier splits a single code into separate charges. - Geography — Medicare's locality adjustment alone can swing the same code 30%+ between cities.
- Your deductible & coinsurance — even a "covered" service can leave you owing thousands until your out-of-pocket max is hit.
Tip: Hospitals are required by federal price transparency rules to publish their standard charges and negotiated rates. Search "[hospital name] price transparency" or use the CMS Hospital Price Transparency tool to compare before a planned procedure.
