What CPT 90937 actually is
Medical service or evaluation-and-management code (CPT 90937). E&M codes describe office, ER, hospital, and consult visits — chosen by the complexity and time of the encounter.
The number above is one piece of context. The other two benchmarks worth knowing:
Hospital cash-pay rate
Federally required to be published by every US hospital under 45 CFR §180.50 (the Hospital Price Transparency rule). The hospital’s own machine-readable file is the authoritative source. Same code; rates vary widely by facility.
Insurance-negotiated rate
Whatever your specific insurance plan and the specific facility have contracted for the same code. Visible on your Explanation of Benefits (EOB) after the claim posts.

$90 for code 90937, set in federal law and updated annually by CMS. Used as the floor benchmark in most bill-review work.
Where CPT 90937 commonly shows up on a bill
Common patterns to look at when reviewing this code:
- 01.A code billed at the global rate when only a partial component was rendered (modifier -26 or -TC may apply).
- 02.The same code billed multiple times for what appears to be the same encounter.
- 03.An item billed without supporting documentation in the medical record.
These patterns are documented in CMS billing guidance, the National Correct Coding Initiative (NCCI) edits, and Office of Inspector General audit reports. None of them are accusations about any specific bill or facility — they’re the checks that exist because the patterns themselves exist.
How to check CPT 90937 on your bill
A few quick checks you can run yourself:
- 01.Pull your itemized bill and find this code. Check the units — a units error quietly multiplies the charge.
- 02.Look for the same code billed more than once for a single visit.
- 03.Only have a summary? Request the itemized bill in writing (HIPAA §164.524) so you can see every code.
