Chronic tubotympanic suppurative otitis media

This code represents a persistent, long-standing infection and inflammation of the middle ear and Eustachian tube, characterized by a chronic discharge through a tympanic membrane perforation. It signifies a non-cholesteatomatous form of chronic otitis media where the infection is primarily mucosal.

Use this code for patients diagnosed with chronic middle ear infection accompanied by a perforated eardrum and ongoing purulent drainage, specifically when the condition is identified as tubotympanic. Documentation should clearly indicate chronicity, the presence of a perforation, and active suppuration without evidence of cholesteatoma.

• Differentiate from chronic atticoantral suppurative otitis media, which involves bone erosion and often cholesteatoma.
• Ensure documentation specifies "chronic" and "suppurative" to support this code.
• Do not use for acute otitis media or serous otitis media.
