What CPT 31237 actually is

Surgical procedure (CPT 31237). Surgery codes cover everything from minor in-office procedures to major operating-room work. The Medicare global package generally bundles pre-op and routine post-op care into the surgery payment.

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.

  • Medicare allowed amount (this page)

    $274 for code 31237, set in federal law and updated annually by CMS. Used as the floor benchmark in most bill-review work.

Where CPT 31237 commonly shows up on a bill

Common patterns to look at when reviewing this code:

  • 01.Surgery codes billed alongside the components they already include — the CMS global package generally bundles pre-op visits and routine post-op care into the surgical fee.
  • 02.Bilateral procedures billed twice instead of once with the bilateral modifier (-50).
  • 03.Co-surgeons or assistants billed at full fee where federal rules allow only a percentage.

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.

Common questions about CPT 31237

How much does CPT 31237 cost?
Medicare's national-average non-facility allowed amount for CPT 31237 is approximately $274 as of 2026-01-01. Hospital cash-pay rates and commercial-insurance contracted rates for the same code are typically higher; the gap is what most billing reviews focus on.
Why is my CPT 31237 bill higher than $274?
Three common reasons: (1) the rate above is non-facility — bills from inpatient hospital settings can be paid differently, (2) commercial insurance contracts and hospital chargemasters are not bound by Medicare rates and often run several multiples higher, and (3) modifiers on the bill may add or subtract from the base rate. The federally-mandated Hospital Price Transparency file for the facility that billed you is the authoritative source for the cash-pay and insurance-negotiated rates at that specific hospital.
Can I dispute a CPT 31237 charge?
Yes. Federal and state consumer-protection law gives every patient the right to (1) request an itemized statement (HIPAA §164.524), (2) receive a Good Faith Estimate before scheduled service (No Surprises Act, 2022), (3) dispute amounts billed without prior consent or proper notice, and (4) apply for charity care if the facility is a 501(c)(3) non-profit (ACA §501(r)). The benchmark above is one piece of evidence; the hospital's own HPT file is another.
What's the source of this number?
The CMS Physician Fee Schedule (PFS) — published annually by the Centers for Medicare & Medicaid Services and required by 42 USC §1395w-4 to be publicly available. We refresh from CMS quarterly. Last updated: 2026-01-01.

P.S. If you’re holding a bill with code 31237on it right now, the fastest path is to run it through the audit — it takes just a few minutes and shows the exact gap between what was charged and the $274 benchmark above. Start the audit →

P.P.S. If the bill came from a non-profit hospital, federal law (ACA §501(r)) requires them to offer charity care to patients below specific income thresholds. We auto-check 501(c)(3) status against the IRS Publication 78 database and draft the application letter when applicable.

P.P.P.S. The $274number above is a benchmark, not a verdict. The right question on any specific bill is whether the documentation in your medical record supports the code that was billed — that’s what every bill-review process ultimately comes down to.
