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 service locality. These locality-adjusted RVUs are summed and multiplied by the annual national conversion factor to produce the allowed amount. Practice-expense RVUs often differ between non-facility (e.g., office) and facility (e.g., hospital) settings, which can change the total payment even though the work and malpractice components stay the same. Because GPCIs and the conversion factor are updated annually, the resulting dollar amount can shift from year to year even if the RVUs themselves do not change.

RVUs — work 7.03, practice expense 7.68 (non-facility) / 7.68 (facility), malpractice 1.48 — × 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.
Modifiers, multiple-procedure reductions, sequestration, and annual budget-neutrality adjustments can change the final amount.
Always verify current rates with your Medicare Administrative Contractor (MAC) before billing.

Frequently asked

Why does the facility amount differ from the non-facility amount?

The practice-expense RVU component is calculated differently depending on whether the service is performed in a facility (like a hospital) or a non-facility setting (like a physician's office), reflecting different overhead costs.

Does this amount include the patient's share?

No. The figure shown is the total Medicare-allowed amount; Medicare generally pays 80% of this after the deductible, with the remaining 20% owed by the patient or secondary insurer.

Will this amount be the same in my locality?

Not necessarily. The PFS amount is adjusted by locality-specific GPCIs, so the actual allowed amount can vary from the national figure shown here.

Why might this fee change next year?

The conversion factor, GPCIs, and RVUs are reviewed and can be updated annually by CMS, which can raise or lower the allowed amount even if the code itself is unchanged.
