Mix cndct/snrl hear loss,uni,l ear,w unrestr hear cntra side

This code describes a type of hearing loss affecting the left ear where both conductive (sound transmission issues) and sensorineural (inner ear or nerve issues) components are present. The right ear, conversely, has normal, unrestricted hearing.

This code is appropriate when diagnostic audiometry confirms a mixed hearing loss in the left ear, and the right ear's hearing is within normal limits. Documentation should clearly specify the unilateral nature of the mixed hearing loss and the unaffected contralateral ear.

• Ensure documentation explicitly states "mixed" hearing loss and specifies the affected ear as "left" with the contralateral ear being "unrestricted" or "normal."
• Do not use this code if the hearing loss is purely conductive or purely sensorineural; separate codes exist for those conditions.
• Verify laterality carefully; codes for bilateral and right-sided mixed hearing loss are distinct.
