H61.32Acquired stenosis of external ear canal secondary to inflammation and infection

H61.32 is the ICD-10-CM diagnosis code for acquired stenosis of external ear canal secondary to inflammation and infection. 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 (acquired stenosis of external ear canal), H61.32 is specifically for acquired stenosis of external ear canal secondary to inflammation and infection. Related codes cover unspecified (H61.30), secondary to trauma (H61.31) and other acquired stenosis of external ear canal (H61.39).

To report this condition, pick the subcode that matches the documentation: H61.321 (infection), H61.322 (infection), H61.323 (bilateral) and H61.329 (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.
