Unspecified cholesteatoma, left ear

This code signifies the presence of an abnormal, non-cancerous skin growth, known as a cholesteatoma, located within the middle ear or mastoid bone of the left ear. This growth can expand and erode surrounding bone, potentially leading to hearing loss, dizziness, or facial nerve paralysis. The "unspecified" nature indicates that the specific type or origin of the cholesteatoma is not documented.

Use this code when documentation clearly indicates a cholesteatoma affecting the left ear, but the provider has not specified its type (e.g., congenital, acquired primary, acquired secondary). This code is appropriate when the medical record identifies the condition as simply "cholesteatoma, left ear" without further detail.

• Do not use this code if the documentation specifies the type of cholesteatoma (e.g., congenital, attic, mastoid).
• Ensure laterality is clearly documented as "left ear" to support this specific code.
• Consider querying the provider for more specific documentation regarding the cholesteatoma type if available, to allow for more precise coding.
