Answer: You’ll find multiple options in ICD-10-CM for mixed hearing loss. The correct diagnosis code will depend on the physician’s documentation. The codes available differentiate between unilateral and bilateral, as well as restricted or unrestricted hearing on the contralateral side.

The available code are:

  • H90.A31 (Mixed conductive and sensorineural hearing loss, unilateral, right ear with restricted hearing on the contralateral side)
  • H90.A32 (Mixed conductive and sensorineural hearing loss, unilateral, left ear with restricted hearing on the contralateral side).
  • H90.71 (Mixed conductive and sensorineural hearing loss, unilateral, right ear, with unrestricted hearing on the contralateral side)
  • H90.72 (Mixed conductive and sensorineural hearing loss, unilateral, left ear, with unrestricted hearing on the contralateral side)
  • H90.6 (Mixed conductive and sensorineural hearing loss, bilateral)
  • H90.8 (Mixed conductive and sensorineural hearing loss, unspecified).
