About H47.02

H47.02 is the ICD-10-CM diagnosis code for hemorrhage in optic nerve sheath. It belongs to category H47 (other disorders of optic [2nd] nerve and visual pathways), block H46-H47 (disorders of optic nerve and visual pathways) 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.

Within H47.0 (disorders of optic nerve, not elsewhere classified), H47.02 is specifically for hemorrhage in optic nerve sheath. Related codes cover ischemic optic neuropathy (H47.01), optic nerve hypoplasia (H47.03) and other disorders of optic nerve, not elsewhere classified (H47.09).

To report this condition, pick the subcode that matches the documentation: H47.021 (right eye), H47.022 (left eye), H47.023 (bilateral) and H47.029 (unspecified eye).

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