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 geographically adjusted RVUs are summed and multiplied by the annual conversion factor (a dollar-per-RVU rate set by CMS) to produce the allowed amount. Practice expense RVUs typically differ between non-facility settings (e.g., physician office) and facility settings (e.g., hospital, ASC) because overhead costs differ; in some codes, including this one, the non-facility and facility PE RVUs are the same, so the national amounts match. The conversion factor and RVUs are updated annually and can change due to budget-neutrality adjustments.

RVUs — work 11.2, practice expense 6.93 (non-facility) / 6.93 (facility), malpractice 1.63 — × the locality GPCIs × the 2026 conversion factor of $33.40.

Good to know

This is an estimate only, not a guarantee of payment — actual reimbursement depends on claim-specific factors.
Medicare typically pays 80% of the allowed amount after the patient meets the Part B deductible; the patient or secondary insurer is generally responsible for the remainder.
Modifiers (e.g., bilateral, multiple procedure, assistant surgeon) can increase or decrease the final payment.
Sequestration and annual budget-neutrality adjustments can shift amounts slightly from year to year.
Locality-specific GPCIs mean the actual paid amount can differ from the national figure shown here.
Always verify current rates and coverage rules with your Medicare Administrative Contractor (MAC).

Frequently asked

Why does the facility amount equal the non-facility amount for this code?

When the practice expense RVU is the same in both non-facility and facility settings, as is the case here, the two calculated amounts end up equal. This is common for certain procedure codes where CMS determines overhead costs don't differ meaningfully by site of service.

Why can't you show me the official CPT code description?

CPT codes and their descriptors are copyrighted and licensed by the American Medical Association (AMA). This page refers to the code generically and does not reproduce the AMA's descriptor text.

Will my locality's payment match the national amount shown?

Not necessarily. The national amount uses a standardized GPCI, while actual locality-specific payments are adjusted using that locality's own GPCI values, which can push the amount higher or lower.

Does this page account for sequestration or other federal payment reductions?

No. Sequestration and similar adjustments are applied separately during claims processing and are not reflected in the RVU-based calculation shown here.
