ICD-10 Code H90 – Conductive and sensorineural hearing loss (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H90 – Conductive and sensorineural hearing loss
What it is
H90 identifies hearing loss that includes both conductive and sensorineural components. Use it when documentation shows mixed involvement of the outer or middle ear and the inner ear or auditory nerve.
Clinical signs
Clinical features vary; refer to documentation. Common findings include reduced hearing on exam, abnormal audiology results, and evidence of both conductive and sensorineural impairment.
When to use this code
Use H90 when the record clearly states mixed, conductive and sensorineural hearing loss. It may apply when audiology or specialist notes describe combined mechanisms rather than a single type.
If the documentation only says “hearing loss” or does not specify the type, check documentation before assigning H90. Code the documented subtype when a more specific diagnosis is available.
Do not use for
Do not use H90 for purely conductive hearing loss, purely sensorineural hearing loss, or unspecified hearing loss. Do not assume a mixed diagnosis without clear provider documentation.
Coding tip
Look for the exact phrase “conductive and sensorineural” or “mixed hearing loss” in the assessment before coding H90.
