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) assigned to the code: physician work, practice expense, and malpractice risk. Each RVU component is adjusted by Geographic Practice Cost Indices (GPCIs) specific to the locality where the service is performed, reflecting local cost-of-living and practice-cost differences. The 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 often have different practice-expense RVUs, which is why the two allowed amounts can differ — though for this code they happen to be the same.

RVUs — work 13.39, practice expense 13.75 (non-facility) / 13.75 (facility), malpractice 2.85 — × 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 annual Part B deductible is met; the patient or secondary payer is generally responsible for the remainder.
Modifiers, multiple-procedure reductions, sequestration, and annual budget-neutrality adjustments can change the actual paid amount.
Rates vary by locality based on GPCI adjustments; always confirm the exact figure with your Medicare Administrative Contractor (MAC).

Frequently asked

Why do I see two different allowed amounts for the same code?

Medicare publishes separate non-facility and facility rates because practice-expense RVUs differ depending on whether the service is performed in an office versus a facility like a hospital. For this code, the two amounts happen to be equal.

Why does the fee differ by locality?

Each Medicare locality has its own Geographic Practice Cost Indices (GPCIs), which adjust the work, practice expense, and malpractice RVUs to reflect regional cost differences before the conversion factor is applied.

Does this page tell me what CPT 24420 actually describes?

No. CPT code descriptors are copyrighted by the American Medical Association and cannot be reproduced here. Consult your CPT codebook or your MAC's fee schedule documentation for the official descriptor.

Is this the amount my practice will actually be paid?

Not necessarily. This is a PFS-based estimate. Final payment depends on patient deductible status, applicable modifiers, secondary insurance, sequestration, and any annual budget-neutrality adjustments CMS applies.
