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 the Geographic Practice Cost Index (GPCI) for the specific locality where the service is billed. These locality-adjusted RVUs are summed and multiplied by the annual Medicare conversion factor to produce the allowed amount. Non-facility (e.g., office) and facility (e.g., hospital) settings can use different practice-expense RVUs, which is why the two amounts may differ; for this code they happen to be reported as the same. The conversion factor is set annually by CMS and can change due to legislation or budget-neutrality adjustments.

RVUs — work 5.6, practice expense 7.11 (non-facility) / 7.11 (facility), malpractice 1.21 — × 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 paid amount.
Locality-specific GPCI values can shift this amount up or down 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 fee schedule amount for this code differ by locality?

The PFS formula applies Geographic Practice Cost Indices (GPCIs) to the work, practice expense, and malpractice RVUs to reflect regional cost differences, which changes the final dollar amount by locality even though the RVUs themselves stay the same.

Why are the non-facility and facility amounts the same for this code?

When the practice-expense RVU is reported as identical for both settings, the resulting allowed amounts will match; this can happen for codes where CMS has not set a separate facility PE value.

Does this amount represent what Medicare will actually pay?

No — it's an estimated allowed amount before the standard 20% coinsurance, deductible status, modifiers, and any sequestration or claim-specific adjustments are applied.
