Chronic myringitis, bilateral

This code signifies a persistent inflammation of the eardrum (tympanic membrane) affecting both ears. This chronic condition often involves thickening, granulation, or ulceration of the tympanic membrane, distinct from acute infections.

Apply this code when documentation clearly indicates a long-standing, non-resolving inflammation of both tympanic membranes. Supporting documentation should specify the chronic nature and bilateral involvement, often noted during otoscopic examination.

• Ensure the documentation explicitly states "chronic" and "bilateral" to support this specific code.
• Differentiate from acute myringitis (H73.0-) and other tympanic membrane disorders.
• Consider any underlying causes or associated conditions that may require additional coding.
