About H15.1

H15.1 is the ICD-10-CM diagnosis code for episcleritis. It belongs to category H15 (disorders of sclera), block H15-H22 (disorders of sclera, cornea, iris and ciliary body) and chapter 7 (diseases of the eye and adnexa). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within H15 (disorders of sclera), H15.1 is specifically for episcleritis. Related codes cover scleritis (H15.0), other disorders of sclera (H15.8) and unspecified disorder of sclera (H15.9).

To report this condition, pick the subcode that matches the documentation: H15.10 (episcleritis), H15.11 (periodica fugax) and H15.12 (episcleritis).

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