Maximum units per day (MUE)

Medicare’s Medically Unlikely Edit caps this code at 1 unit 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 PFS amounts are built from three Relative Value Units (RVUs): physician work, practice expense (PE), and malpractice (MP). Each RVU component is adjusted by the Geographic Practice Cost Indices (GPCIs) specific to the Medicare locality where the service is performed, then the adjusted RVUs are summed and multiplied by the annual conversion factor to produce a dollar amount. Practice expense RVUs often differ between non-facility (e.g., physician office) and facility (e.g., hospital) settings, which is why the two amounts can differ. For this code, the non-facility and facility PE RVUs shown are the same, so the resulting national amounts are equal, but locality-adjusted amounts may still vary.

RVUs — work 8.88, practice expense 8.46 (non-facility) / 8.46 (facility), malpractice 1.9 — × the locality GPCIs × the 2026 conversion factor of $33.40.

Good to know

This is an estimate only, based on national RVUs and the annual conversion factor — actual payment depends on the specific Medicare Administrative Contractor (MAC) and locality GPCIs.
Medicare typically pays 80% of the approved amount after the patient's Part B deductible is met; the beneficiary or secondary payer is responsible for the remainder.
Modifiers, multiple-procedure reductions, sequestration, and annual budget-neutrality adjustments can change the final paid amount.
Always confirm current-year rates and locality-specific figures with your MAC before billing or appealing a claim.

Frequently asked

Why do the non-facility and facility amounts differ for some codes but not others?

The difference comes from the practice expense RVU component, which accounts for overhead costs like supplies and staff time. When a procedure is typically performed in a facility (e.g., hospital), Medicare assumes the facility bears more of the overhead, so the physician's PE RVU—and thus the facility payment—may be lower. If the PE RVUs are identical in both settings, the amounts will match.

Does this page show what I will actually be paid?

No. It shows the estimated national PFS allowed amount derived from standard RVUs and the conversion factor. Your actual payment depends on your specific locality GPCIs, any applicable modifiers, and current Medicare policy adjustments.

Why isn't the CPT code description shown here?

CPT code descriptors are copyrighted by the American Medical Association (AMA) and require a license to reproduce. This page refers to the code generically for that reason.

How often do these RVUs and the conversion factor change?

CMS updates RVUs and the conversion factor annually through rulemaking, and mid-year adjustments can occur due to legislation or budget-neutrality requirements. Always check the current year's Medicare Physician Fee Schedule for the latest values.
