Denial reason code 54MUE FAQ

Q: We received denial reason code 54MUE. What steps can we take to avoid this reason code?
A: You received this reason code because the units of service billed are in excess of the allowable units based on the National Correct Coding Initiative (NCCI) external link policy for Medically Unlikely Edits (MUE) external link. If units billed are medically necessary, you can submit a request for a redetermination. Visit the Appeals page for information on the Medicare appeals process.
