A dermatology office claims three units of a procedure whose Medically Unlikely Edit (MUE) value is 1 for the same date of service, with no documentation supporting a rare clinical exception pathway. What should the CCS-P coder expect?
Select an answer to reveal the explanation.
Short Explanation
An MUE is like a speed limit for units—CMS says going past that number is almost never believable. Stacking three when the limit is one usually means a denial, not a bigger check.
Full Explanation
Medically Unlikely Edits set maximum units of service for a HCPCS/CPT code that a provider would report under most circumstances for a single beneficiary on a single date of service (or per adjudication rules tied to the MUE). Excess units without a recognized justification pathway are typically denied. MUEs apply to professional claims as well as other settings; modifiers such as 76 do not automatically override an MUE.
