Atrophic flaccid tympanic membrane, unspecified ear

This code signifies a thinning and loss of elasticity of the eardrum, resulting in a floppy or lax appearance without specifying which ear is affected. This condition typically arises from chronic inflammation or previous perforations that have healed with scar tissue, leading to impaired sound transmission.

Use this code when documentation indicates an atrophic and flaccid tympanic membrane without further specification of the affected ear. This diagnosis is often made during otoscopic examination. Supporting documentation should clearly describe the physical characteristics of the tympanic membrane.

• Do not use this code if the laterality (left or right ear) is documented; instead, choose the more specific H73.811 or H73.812.
• This code describes an anatomical change, not an active infection or acute perforation.
• Consider co-reporting with codes for underlying causes if documented, such as chronic otitis media.
