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

The Medicare PFS amount is built from three Relative Value Units (RVUs) — physician work, practice expense, and malpractice — each adjusted by the Geographic Practice Cost Indices (GPCIs) for the specific locality where the service is performed. These locality-adjusted RVUs are summed and multiplied by the annual Medicare conversion factor to produce the allowed amount. Practice-expense RVUs differ between non-facility (e.g., office) and facility (e.g., hospital) settings, which is why this code may show two different totals. The national figures use the national GPCI (1.0 for each component) and the published conversion factor for the year shown.

RVUs — work 13.36, practice expense 9.89 (non-facility) / 9.89 (facility), malpractice 2.85 — × 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.
Modifiers, sequestration, multiple-procedure reductions, and annual budget-neutrality adjustments can change the final paid amount.
Always confirm final pricing and coverage with your Medicare Administrative Contractor (MAC) before billing.

Frequently asked

Why does the amount differ by locality?

Medicare adjusts payment using Geographic Practice Cost Indices (GPCIs) that reflect regional differences in wages, rent, and malpractice costs, so the same code can pay differently depending on where the service is furnished.

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

When the practice-expense RVU is identical for both settings, as shown here, the calculated allowed amount is the same regardless of place of service.

Does this amount include the patient's deductible and coinsurance?

No. The figure shown is the total allowed amount before Medicare's standard 80/20 split and any unmet deductible are applied.

Will this exact amount be paid on my claim?

Not necessarily. Modifiers, secondary payer rules, sequestration, and local MAC pricing policies can all affect the final reimbursement, so this figure should be treated as an estimate.
