Other chronic suppurative otitis media, left ear

This code signifies a persistent, purulent infection of the middle ear in the left ear, excluding specific types like tubotympanic or atticoantral. It indicates ongoing inflammation and discharge, often associated with a tympanic membrane perforation.

Apply this code when documentation specifies chronic suppurative otitis media affecting the left ear, without further classification into tubotympanic or atticoantral types. The medical record should clearly indicate the chronicity and purulent nature of the infection.

• Ensure the documentation specifies "left ear" and "chronic suppurative" to differentiate from acute or non-suppurative forms.
• Do not use if the documentation specifies tubotympanic (H66.3X1) or atticoantral (H66.3X3) types; select the more specific code.
• Look for associated conditions like tympanic membrane perforation (H72.-) or cholesteatoma (H71.-) which may require additional coding.
