Atrophic nonflaccid tympanic membrane, right ear

This code indicates a condition of the right eardrum where it has thinned and lost its normal elasticity, but without being floppy or lax. This atrophy suggests a previous inflammatory process or chronic ear condition that has altered the structural integrity of the tympanic membrane.

Apply this code when documentation specifies atrophy of the right tympanic membrane that is explicitly described as "nonflaccid." This typically occurs following resolution of otitis media or trauma, where the eardrum appears thin and retracted but maintains some tension.

• Differentiate from flaccid tympanic membrane conditions (e.g., H73.81x) which describe a floppy or lax eardrum.
• Ensure laterality is clearly documented (right ear).
• Consider co-occurring conditions such as chronic otitis media or perforation if present and documented.
