Maximum units per day (MUE)

Medicare’s Medically Unlikely Edit caps this code at 2 units 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) assigned to a code: 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, then the adjusted RVUs are summed and multiplied by the annual national conversion factor to produce a dollar amount. Non-facility and facility rates differ mainly because the practice-expense RVU is higher in non-facility settings (where the provider bears more overhead) and lower in facility settings (where the facility absorbs most overhead costs). This same formula is recalculated each year as RVUs, GPCIs, and the conversion factor are updated.

RVUs — work 4.19, practice expense 13.62 (non-facility) / 5.86 (facility), malpractice 0.92 — × the locality GPCIs × the 2026 conversion factor of $33.40.

Good to know

This is an estimate only, not a guarantee of payment or coverage.
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.
Actual payment can vary based on locality, applicable modifiers, sequestration reductions, and annual budget-neutrality adjustments.
Always verify the final allowed amount and any site-of-service or modifier rules with your Medicare Administrative Contractor (MAC).

Frequently asked

Why is the facility amount lower than the non-facility amount?

In a facility setting, the hospital or facility bills separately for overhead costs, so the practice-expense RVU used to price the physician service is lower than when the same service is performed in a non-facility setting like an office.

Does this amount reflect what I'll actually be paid?

No. It's an estimate based on standard PFS inputs. Your specific payment can differ due to locality GPCIs, modifiers, secondary payer coordination, and other adjustments like sequestration.

Why do amounts change each year?

CMS updates RVUs, GPCIs, and the conversion factor annually, and may apply budget-neutrality adjustments, which can raise or lower the calculated fee from one year to the next.
