ICD-10 Code H74.20 – Discontinuity and dislocation of ear ossicles, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H74.20 – Discontinuity and dislocation of ear ossicles, unspecified ear
What it is
This code identifies a break in continuity or displacement of the middle-ear ossicles, without laterality specified. It is used when documentation confirms an ossicular chain problem but does not name the exact bone or ear.
Clinical signs
Common findings include conductive hearing loss and a history of ear trauma, chronic ear disease, or prior surgery. Clinical features vary; refer to documentation.
When to use this code
Use H74.20 when the record states discontinuity, separation, or dislocation of the ossicles and does not specify left or right ear. It also fits cases where imaging or operative notes confirm ossicular disruption but the exact ossicle is not identified. You should confirm the diagnosis is current, not merely historical.
Do not use for
Do not use this code for nonspecific hearing loss alone or for other middle-ear disorders without ossicular disruption. Check documentation if the note describes congenital anomalies, infection, or trauma without confirmed ossicle discontinuity.
Coding tip
Query for laterality and the specific ossicle when the note is incomplete, because H74.20 is only for unspecified ear.
