Other marginal perforations of tympanic membrane, bilateral

This code signifies a non-central perforation of the eardrum, affecting both ears. These perforations are located at the periphery of the tympanic membrane, not involving the central pars tensa, and are not due to acute otitis media or traumatic injury.

Apply this code when documentation specifies bilateral marginal tympanic membrane perforations of an unspecified or other non-traumatic, non-acute origin. This is often seen in cases of chronic otitis media where the perforation has stabilized. Supporting documentation should clearly indicate the marginal location and bilateral involvement.

• Differentiate from central perforations (H72.1-) and traumatic perforations (S09.2-).
• Ensure documentation explicitly states "bilateral" and "marginal" to support this specific code.
• If the laterality is not specified, an unspecified laterality code should be considered if available, or query the provider.
