About H61.01

H61.01 is the ICD-10-CM diagnosis code for acute perichondritis of external ear. 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 H61.0 (Chondritis and perichondritis of external ear), H61.01 is specifically for acute perichondritis of external ear. Related codes cover unspecified perichondritis of external ear (H61.00), chronic perichondritis of external ear (H61.02) and Chondritis of external ear (H61.03).

To report this condition, pick the subcode that matches the documentation: H61.011 (ear), H61.012 (ear), H61.013 (bilateral) and H61.019 (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.
