H47.6Disorders of visual cortex

H47.6 is the ICD-10-CM diagnosis code for disorders of visual cortex. 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 (other disorders of optic [2nd] nerve and visual pathways), H47.6 is specifically for disorders of visual cortex. Related codes cover disorders of optic nerve, not elsewhere classified (H47.0), papilledema (H47.1), optic atrophy (H47.2), other disorders of optic disc (H47.3), disorders of optic chiasm (H47.4), disorders of other visual pathways (H47.5) and unspecified disorder of visual pathways (H47.9).

To report this condition, pick the subcode that matches the documentation: H47.61 (blindness), H47.62 (in (due to) inflammatory disorders), H47.63 (in (due to) neoplasm) and H47.64 (in (due to) vascular disorders).

Don't report H47.6 together with the conditions in its Excludes1 note: injury to visual cortex S04.04-.

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