Chronic tubotympanic suppurative otitis media, bilateral

This code signifies a persistent, purulent inflammation of the middle ear and Eustachian tube affecting both ears. It is characterized by chronic discharge through a tympanic membrane perforation, often associated with mucosal edema and granulation tissue within the middle ear space.

Apply this code when documentation clearly indicates a long-standing, active suppurative otitis media involving both ears, specifically of the tubotympanic type. Supporting documentation should include physician notes detailing chronic otorrhea, bilateral tympanic membrane perforations, and evidence of middle ear inflammation.

• Differentiate from acute or recurrent acute otitis media; this code is for chronic conditions.
• Ensure laterality is explicitly documented as bilateral; avoid using unspecified laterality codes if bilateral involvement is known.
• Look for terms like "chronic suppurative otitis media," "chronic otorrhea," or "perforated eardrum with discharge" in both ears.
