Otosclerosis w oval window, nonobliterative, left ear

Otosclerosis involving oval window, nonobliterative, left ear

AIClinical Context

Clinical Description

This code signifies a condition where abnormal bone growth affects the stapes (oval window) in the left ear, but the window is not completely blocked. This bony overgrowth impairs the stapes' ability to vibrate, leading to conductive hearing loss. It specifically identifies otosclerosis that has not yet caused complete obliteration of the oval window.

When to Use

Use this code for patients diagnosed with otosclerosis affecting the left ear, where audiological and imaging studies confirm involvement of the oval window without complete fusion or closure. Documentation should clearly state "nonobliterative" or similar terminology indicating the oval window is still partially open.

Coding Tips

Ensure documentation specifies "left ear" and "nonobliterative" involvement of the oval window.
Distinguish from obliterative otosclerosis (H80.1-) and cochlear otosclerosis (H80.2-).
Always code the laterality (left, right, bilateral) accurately based on physician documentation.
