Maximum units per day (MUE)

Medicare’s Medically Unlikely Edit caps this code at 1 unit per patient per day — Date of Service Edit: Policy. 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 prices each code using three Relative Value Units (RVUs): physician work, practice expense, and malpractice. Each RVU component is adjusted by Geographic Practice Cost Indices (GPCIs) specific to the locality where the service is performed, reflecting regional differences in costs. The adjusted RVUs are summed and multiplied by the annual Medicare Conversion Factor (CF) to produce the allowed amount. Practice-expense RVUs differ between non-facility and facility settings because facility settings (like hospitals) typically bear more of the overhead cost, which lowers the physician-side practice-expense RVU.

RVUs — work 8.29, practice expense 11.46 (non-facility) / 11.46 (facility), malpractice 1.21 — × 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 approved amount after the annual Part B deductible is met; the patient or secondary insurer is responsible for the remainder.
Actual payment varies by locality, applicable modifiers, sequestration reductions, and annual budget-neutrality adjustments.
Always confirm the exact allowed amount and coverage policy with your Medicare Administrative Contractor (MAC) before billing.

Frequently asked

Why does the allowed amount change by location?

Medicare adjusts payment using Geographic Practice Cost Indices (GPCIs), which account for regional differences in the cost of physician work, practice expense, and malpractice insurance.

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

When the practice-expense RVU is identical in both settings, the resulting allowed amount does not differ, meaning the procedure is priced the same whether performed in an office or a facility.

Does this page show what Medicare will actually pay?

No. This page shows the estimated Medicare PFS allowed amount. Medicare generally pays 80% of that amount after the deductible, and the final reimbursement can be affected by modifiers, sequestration, and other adjustments.
