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 payment is built from three Relative Value Units (RVUs) — physician work, practice expense, and malpractice — assigned to each code. Each RVU component is adjusted by Geographic Practice Cost Indices (GPCIs) specific to the locality where the service is furnished, to account for regional cost differences. The adjusted RVUs are summed and multiplied by the annual national conversion factor (a dollar figure set each year by CMS) to produce the allowed amount. Non-facility and facility amounts can differ because the practice-expense RVU changes depending on whether the service is performed in a physician office (non-facility) versus a hospital or other facility setting, reflecting differing overhead costs.

RVUs — work 61.51, practice expense 29.52 (non-facility) / 29.52 (facility), malpractice 13.14 — × the locality GPCIs × the 2026 conversion factor of $33.40.

Good to know

This is an estimate only, based on national RVUs, GPCIs, and the conversion factor for the stated year — actual payment may differ.
Medicare typically pays 80% of the allowed amount after the patient's deductible is met; the patient or secondary insurer is responsible for the remainder.
Modifiers, multiple-procedure reductions, bilateral rules, and other claim-specific adjustments can change the final paid amount.
Annual budget-neutrality adjustments, sequestration, and legislative changes to the conversion factor can alter payment year to year.
Local Medicare Administrative Contractor (MAC) policies and locality-specific GPCIs may result in a different amount than the national figure shown here.
Always verify the current, locality-specific rate with your MAC or official CMS fee schedule tools before billing or appealing a claim.

Frequently asked

Why does the amount shown differ from what my MAC paid?

The figure here is a national estimate calculated from standard RVUs, GPCIs, and the conversion factor. Your MAC's actual payment reflects your specific locality, any applicable modifiers, and current claim-processing rules, which can shift the result.

Why are the non-facility and facility amounts different (or the same)?

The practice-expense RVU component varies depending on whether the service is reported as performed in a non-facility (e.g., office) or facility (e.g., hospital) setting, because overhead costs differ. If the figures shown are equal, it means the practice-expense RVU was the same in both settings for this code and year.

Does this page tell me what the patient will owe?

Not directly. Medicare generally pays 80% of the allowed amount after the deductible is met, leaving the patient responsible for the remaining 20% coinsurance, unless secondary coverage applies. Exact patient liability depends on deductible status and supplemental insurance.

Can I use this number to predict next year's payment?

Not reliably. The conversion factor and RVUs are updated annually by CMS, and budget-neutrality adjustments or legislation can change payment amounts from one year to the next.
