Atrophic flaccid tympanic membrane, bilateral

This code signifies a thinning and loss of elasticity of both eardrums, resulting in a floppy or lax appearance. This condition can be a sequela of recurrent otitis media or chronic inflammation, leading to impaired sound transmission.

Apply this code when documentation explicitly states "atrophic flaccid tympanic membrane, bilateral" or similar phrasing indicating a thinned, non-retracted, and floppy eardrum in both ears. This often occurs after resolution of middle ear effusions or perforations.

• Ensure the documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Distinguish from tympanosclerosis (H74.0-), which involves calcification and hardening, not flaccidity.
• Do not code if the tympanic membrane is retracted (H73.0-) or perforated (H72.-).
