Postprocedural stenosis of right external ear canal

This code signifies a narrowing or obstruction of the right external auditory canal that occurs as a direct consequence of a previous medical or surgical procedure. This stenosis can impede sound transmission and may lead to conductive hearing loss or recurrent infections. It is a complication arising from an intervention rather than a congenital or naturally occurring condition.

Use this code when documentation clearly indicates a postprocedural narrowing of the right external ear canal. This typically follows otologic surgeries, such as tympanoplasty, mastoidectomy, or canalplasty, or procedures involving the external ear. The medical record should specify the laterality (right) and the causal link to a prior procedure.

• Ensure documentation explicitly states "postprocedural" and specifies the right ear.
• Do not use for congenital stenosis or stenosis due to trauma not related to a procedure.
• Consider sequencing this code after the code for the underlying ear condition or the complication that necessitated the original procedure, if applicable.
