Acute suppr otitis media w spon rupt ear drum, left ear

This code signifies an acute bacterial infection of the middle ear, specifically affecting the left ear, which has progressed to the point of spontaneous perforation of the tympanic membrane. The "suppurative" aspect indicates the presence of pus or purulent discharge within the middle ear space.

This code is appropriate when documentation clearly states acute otitis media with evidence of a ruptured eardrum in the left ear, occurring without surgical intervention. Clinical notes should describe symptoms such as sudden ear pain relief followed by otorrhea, and otoscopic examination confirming a perforation.

• Ensure laterality is explicitly documented as "left ear" to support this specific code.
• Distinguish from chronic otitis media with perforation, which uses different code categories.
• Do not use if the rupture was iatrogenic (e.g., during myringotomy).
