Mixed conductive and sensorineural hearing loss, unspecified

This code signifies a type of hearing impairment characterized by components of both conductive and sensorineural hearing loss, where the specific cause or detailed nature of the mixed loss is not documented. It indicates a combined problem with sound transmission through the outer/middle ear and sound perception by the inner ear/auditory nerve.

Use this code when documentation clearly states "mixed conductive and sensorineural hearing loss" but lacks further specificity regarding laterality (e.g., right, left, bilateral) or the underlying etiology. It is appropriate when the provider has diagnosed a mixed loss but has not yet determined or documented the specific causes of the conductive and sensorineural components.

• Avoid using this code if laterality is documented; instead, choose a more specific code from the H90.A or H90.B series.
• Do not use if the specific causes of the conductive and sensorineural components are known and documented; code those specific conditions.
• This code is for an unspecified mixed loss; query the provider for greater specificity if possible.
