H61.39Other acquired stenosis of external ear canal

H61.39 is the ICD-10-CM diagnosis code for other acquired stenosis of external ear canal. It belongs to category H61 (other disorders of external ear), block H60-H62 (diseases of external ear) and chapter 8 (diseases of the ear and mastoid process). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.

Within H61.3, choose H61.39 (Other acquired stenosis of external ear canal) only when documentation doesn't support a more specific option: unspecified (H61.30), secondary to trauma (H61.31) and secondary to inflammation and infection (H61.32).

To report this condition, pick the subcode that matches the documentation: H61.391 (canal), H61.392 (canal), H61.393 (bilateral) and H61.399 (unspecified ear).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
