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 locality where the service is billed. The adjusted RVUs are summed and multiplied by the annual conversion factor (a national dollar figure set by CMS) to produce the allowed amount. Practice-expense RVUs differ between non-facility (e.g., office) and facility (e.g., hospital, ASC) settings because overhead costs differ; for this code, those RVU values are shown above and may be equal or different depending on the year's final rule. The resulting figure is the Medicare-allowed amount before any adjustments for modifiers, assistant surgeon rules, multiple-procedure reductions, or sequestration.

RVUs — work 7.47, practice expense 7.55 (non-facility) / 7.55 (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; the patient or secondary payer is responsible for the remainder.
Modifiers (e.g., bilateral, multiple procedure, assistant-at-surgery), place-of-service, and sequestration can change the final paid amount.
Annual budget-neutrality adjustments and conversion factor updates mean amounts change each calendar year.
Always verify the current locality-specific fee and any claim-specific edits with your Medicare Administrative Contractor (MAC).

Frequently asked

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

The practice-expense RVU component is calculated differently depending on whether the service is performed in a facility (where the facility absorbs overhead costs) versus a non-facility setting (where the physician's practice bears those costs). This can make the facility rate lower, higher, or the same as the non-facility rate.

Does this amount reflect what my specific locality will be paid?

Only if the locality-adjusted figure is shown. The national amount uses standardized GPCIs and may differ from your actual locality-specific payment.

Will Medicare pay this full amount?

No. Medicare generally reimburses 80% of the allowed amount after the Part B deductible is met; the remaining 20% is typically billed to the patient or a secondary payer, subject to any applicable adjustments.

Why might my remittance advice show a different amount than this estimate?

Claim-level factors such as modifiers, multiple-procedure payment reductions, sequestration, locality mismatches, or mid-year CMS corrections can all cause the actual paid amount to differ from this reference estimate.
