Mixed conductive and sensorineural hearing loss, bilateral

This diagnosis code signifies a hearing impairment affecting both ears, characterized by components of both conductive and sensorineural hearing loss. This means there is a problem with sound transmission through the outer or middle ear, combined with damage to the inner ear or auditory nerve.

Apply this code when documentation clearly indicates a mixed hearing loss affecting both the left and right ears. This typically involves audiometric findings showing both an air-bone gap and elevated bone conduction thresholds bilaterally. Supporting documentation includes audiograms and physician notes detailing the bilateral nature and mixed etiology.

• Ensure the documentation explicitly states "bilateral" or indicates both ears are affected by mixed hearing loss.
• Distinguish from unilateral mixed hearing loss (H90.41, H90.42) or unspecified ear (H90.5).
• Look for specific audiometric findings (e.g., air-bone gap, elevated bone conduction) that confirm both conductive and sensorineural components.
