About H15

H15 is the ICD-10-CM diagnosis code for disorders of sclera. It belongs to 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 4 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: H15.0 (scleritis), H15.1 (episcleritis), H15.8 (sclera) and H15.9 (sclera).

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