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 billing locality. The adjusted RVUs are summed and multiplied by the annual Medicare conversion factor to produce a dollar amount. Practice-expense RVUs typically differ between non-facility and facility settings because overhead costs differ; for this code the practice-expense RVU is the same in both settings, so the national non-facility and facility amounts shown here are equal. Locality-specific amounts can still differ from the national figures because GPCIs vary by region.

RVUs — work 11.64, practice expense 3.71 (non-facility) / 3.71 (facility), malpractice 2.48 — × 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 patient meets the annual Part B deductible; the patient or secondary payer is generally responsible for the remainder.
Modifiers, multiple-procedure reductions, sequestration, and annual budget-neutrality adjustments can change the actual paid amount.
Always verify current rates and coverage policy with your Medicare Administrative Contractor (MAC) before billing or appealing a denial.

Frequently asked

Why does the amount differ by locality?

Each Medicare locality has its own Geographic Practice Cost Indices (GPCIs) for work, practice expense, and malpractice, which adjust the national RVUs to reflect local cost differences before the conversion factor is applied.

Why are the non-facility and facility amounts the same for this code?

The two settings differ based on the practice-expense RVU, which reflects overhead costs. For this code, the practice-expense RVU is identical in non-facility and facility settings, so the calculated amounts match.

Does this amount reflect what the patient will owe?

No. This figure is the Medicare-allowed amount before cost-sharing. The patient's out-of-pocket responsibility depends on deductible status, coinsurance, and any secondary coverage.

Can this amount change during the year?

Yes. Sequestration, legislative adjustments, and mid-year corrections can alter the effective payment even though the published conversion factor and RVUs are set annually.
