Cholesteatoma of external ear, bilateral

This code signifies the presence of a cholesteatoma, which is an abnormal, non-cancerous skin growth that develops in the external ear canal. This specific code indicates that the condition affects both the left and right external ear canals. The growth is typically composed of squamous epithelium and keratin debris.

Use this code when documentation clearly states a diagnosis of cholesteatoma located in the external auditory canal and explicitly specifies its bilateral presence. This diagnosis is often made upon otoscopic examination revealing a pearly white mass, sometimes accompanied by otorrhea or hearing loss.

• Differentiate from middle ear cholesteatoma (H71.-), which is a distinct condition with different anatomical involvement.
• Ensure documentation specifies "external ear" and "bilateral" to accurately assign this code.
• Consider additional codes for associated symptoms like hearing loss (H90.-, H91.-) or otorrhea (H92.0-).
