H74.93
BillableUnspecified disorder of middle ear and mastoid, bilateral
This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).
What This Code Means
This code describes an unspecified problem affecting the middle ear and mastoid bone (the bone behind the ear) on both sides of the head, when the specific condition cannot be identified. It is used when a patient has symptoms or findings in both ears but the exact diagnosis is unclear.
Coding Tips
- •Use this code only when the specific middle ear or mastoid disorder cannot be determined; if a more specific diagnosis is documented (such as otitis media or mastoiditis), use that code instead
- •The 'bilateral' designation means both ears are affected; verify documentation confirms involvement of both sides before assigning this code
