H90.12

Billable

Conductive hearing loss, unilateral, left ear, with unrestricted hearing on the contralateral side

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

Hearing loss in the left ear caused by problems with sound transmission through the middle ear, while the right ear has normal hearing.

Coding Tips

  • •The '12' indicates left ear involvement with unrestricted hearing on the opposite side; use H90.11 for right ear unilateral cases.
  • •Document whether the contralateral ear truly has unrestricted hearing to ensure accurate code selection.
