About H47

H47 is the ICD-10-CM diagnosis code for other disorders of optic [2nd] nerve and visual pathways. It belongs to 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 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: H47.0 (classified), H47.1 (papilledema), H47.2 (atrophy), H47.3 (disc), H47.4 (chiasm), H47.5 (pathways), H47.6 (cortex) and H47.9 (pathways).

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