Partial loss of ear ossicles, bilateral

This code signifies a condition where there is incomplete damage or deterioration of the small bones (malleus, incus, stapes) in both middle ears. This partial loss can lead to conductive hearing impairment due to compromised sound transmission.

Use this code when documentation explicitly states partial ossicular loss affecting both ears, often identified during otoscopic examination, audiometry, or surgical exploration. It is typically associated with chronic otitis media, trauma, or congenital anomalies.

• Ensure documentation specifies "partial" loss and "bilateral" involvement; otherwise, a more general or unilateral code may be appropriate.
• Distinguish from complete ossicular discontinuity (H74.31-) or other middle ear disorders.
• Always code any associated hearing loss (e.g., H90.0-H90.2) as a secondary diagnosis.
