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'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 conversion factor to produce the allowed amount. Practice-expense RVUs differ between non-facility (e.g., office) and facility (e.g., hospital) settings because overhead costs differ, which can change the total payment even when the work and malpractice components stay the same. The conversion factor is updated each year, so the dollar amount can shift annually even if RVUs are unchanged.

RVUs — work 11.97, practice expense 9.99 (non-facility) / 9.99 (facility), malpractice 2.52 — × 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 insurer is responsible for the rest.
Modifiers, place-of-service codes, sequestration, and annual budget-neutrality adjustments can all change the final paid amount.
Locality-specific GPCIs mean the actual allowed amount can differ from the national figure shown here.
Always verify current rates and coverage rules with your Medicare Administrative Contractor (MAC) before billing.

Frequently asked

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

Facility rates typically use lower practice-expense RVUs because Medicare assumes less overhead is borne by the billing provider when the service is performed in a facility setting like a hospital.

Does this amount reflect what Medicare will actually pay?

No. It's an estimate based on national RVUs and the conversion factor. Actual payment depends on your specific locality GPCIs, any applicable modifiers, and current sequestration or policy adjustments.

Why do national and locality amounts differ?

The national amount uses a GPCI of 1.0 for all components, while locality-specific amounts apply the actual GPCIs for work, practice expense, and malpractice in that area, which can raise or lower the total.

Will this code's rate change next year?

Possibly. CMS updates the conversion factor and may revise RVUs annually, and budget-neutrality adjustments can also affect the final allowed amount.
