Maximum units per day (MUE)

Medicare’s Medically Unlikely Edit caps this code at 1 unit per patient per day — Date of Service Edit: Clinical. Units above the MUE are denied; some MUEs can be exceeded only with appropriate documentation and modifiers where policy allows.

How the amount is calculated

Medicare's PFS amount is built from three Relative Value Units (RVUs) — physician work, practice expense, and malpractice — each adjusted by Geographic Practice Cost Indices (GPCIs) specific to the locality where the service is billed. The geographically adjusted RVUs are summed and multiplied by the annual Medicare conversion factor to produce the allowed amount. Practice expense RVUs typically differ between non-facility (e.g., office) and facility (e.g., hospital) settings, since overhead costs differ, though for some codes these values are identical. The conversion factor and RVUs are updated annually and can shift due to budget-neutrality adjustments required by law.

RVUs — work 7.88, practice expense 8.29 (non-facility) / 8.29 (facility), malpractice 1.68 — × the locality GPCIs × the 2026 conversion factor of $33.40.

Good to know

This is an estimate only, not a guarantee of payment.
Medicare typically pays 80% of the allowed amount after the annual Part B deductible is met; the patient or secondary payer is responsible for the remainder.
Actual payment can vary by locality GPCI values, applicable modifiers, multiple-procedure reductions, sequestration, and mid-year or annual budget-neutrality adjustments.
Always verify the current, locality-specific fee with your Medicare Administrative Contractor (MAC) before billing or appealing a denial.

Frequently asked

Why don't the non-facility and facility amounts differ for this code?

Pricing differences between settings come from differences in the practice expense RVU. When the non-facility and facility practice expense RVUs are the same, as shown here, the calculated allowed amounts are also the same.

Why can't you show the CPT code description?

CPT code descriptors are copyrighted and licensed by the American Medical Association (AMA). This page cannot reproduce or paraphrase the official descriptor without a license.

Why does the amount I was paid differ from the national PFS amount shown here?

The national amount uses a standard GPCI factor rather than a locality-specific one. Actual payments depend on the provider's locality, applied modifiers, claim adjustments, and sequestration.

Will this amount change during the year?

It can. CMS may issue mid-year corrections, and the conversion factor and RVUs are revised annually, so amounts should be reverified each calendar year.
