Atrophic nonflaccid tympanic membrane, bilateral

This code signifies a thinning and loss of elasticity in both eardrums, without any associated flaccidity or bulging. It indicates a chronic, non-inflammatory change to the tympanic membrane structure, often due to aging or prior ear conditions. This atrophy can affect sound conduction but does not involve active infection or perforation.

Apply this code when documentation explicitly states "atrophic nonflaccid tympanic membrane, bilateral" or similar phrasing indicating bilateral, non-mobile, thinned eardrums without acute inflammation. This is commonly observed during otoscopic examination in patients with a history of recurrent otitis media or age-related changes. Ensure the physician's notes clearly specify the bilateral involvement and the absence of flaccidity.

• Differentiate from flaccid or retracted tympanic membranes; this code specifically excludes those conditions.
• Confirm bilateral involvement; unilateral atrophy would require a different code.
• Do not use if there is any mention of perforation, acute inflammation, or effusion, as those conditions would take precedence or require additional codes.
