Acquired stenosis of ext ear canal sec to trauma, unsp ear

This code describes a narrowing of the external auditory canal that developed as a result of an injury. This stenosis can impede sound transmission to the eardrum and may lead to hearing loss, recurrent infections, or difficulty with ear hygiene. The "unspecified ear" designation indicates that the laterality of the condition is not documented.

Use this code when documentation clearly states acquired external ear canal stenosis due to trauma, and the affected ear is not specified (e.g., "bilateral" or "right/left ear" is absent). This code is appropriate when the patient presents with symptoms such as conductive hearing loss, otalgia, or recurrent otitis externa following a history of ear trauma.

• Ensure documentation explicitly links the stenosis to a traumatic event.
• If the laterality (right, left, or bilateral) is specified, a more specific code within the H61.31 subcategory should be used.
• Consider co-reporting an external cause code (V00-Y99) to identify the nature and circumstances of the traumatic event, if known and documented.
