Other chronic nonsuppurative otitis media, left ear

This code signifies a persistent, non-infectious inflammation of the middle ear in the left ear, excluding cases with pus formation. This condition often involves fluid accumulation (serous or mucoid) behind the eardrum, leading to hearing impairment.

Apply this code when documentation specifies chronic otitis media of the left ear without evidence of active bacterial infection or suppuration. This is commonly seen in cases of chronic serous otitis media or chronic mucoid otitis media affecting the left ear. Supporting documentation includes physician notes detailing chronic middle ear effusion, tympanometry findings, and audiograms.

• Ensure documentation clearly specifies "chronic" and "nonsuppurative" to differentiate from acute or suppurative forms.
• Verify laterality; this code is specific to the left ear.
• Do not use for acute otitis media or chronic suppurative otitis media, which have distinct codes.
