02 · Codes

Any code, and whether it is one

Hospitals' price files carry every code they bill — and a great many strings that only look like codes. Before a price is shown for one, it has to pass a test that is not a judgment: is this code in a public CMS list, or do hospitals only agree among themselves that it exists? Type a code or a word to look one upⓘ.

17,374

official — in a CMS list list

75,728

hospitals only — well-formed, two or more files, no CMS list list

6,560

unverified strings — malformed or one file only; no price rows list

17,374 / 93,102

codes with an official descriptor; the rest carry a hospital's wording or noneⓘ

Of 98,662 distinct strings the sampled hospitals filed under CPT/HCPCS, 16,596 are codes a CMS list knows and 75,507 are well-formed codes that two or more hospitals agree on. The other 6,559 are chargemaster item numbers, revenue codes and fragments that pass for codes. They are kept here, labelled, because a dataset that hides what it threw away is asking to be trusted rather than checked.

The status and the official descriptors come from these four CMS files; the hospital wordings come from the sampled price files, each linked from its code's page and from the hospital's page.
