About H46.0

H46.0 is the ICD-10-CM diagnosis code for optic papillitis. It belongs to category H46 (optic neuritis), 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 H46 (optic neuritis), H46.0 is specifically for optic papillitis. Related codes cover retrobulbar neuritis (H46.1), nutritional optic neuropathy (H46.2), toxic optic neuropathy (H46.3), other optic neuritis (H46.8) and unspecified optic neuritis (H46.9).

To report this condition, pick the subcode that matches the documentation: H46.00 (unspecified eye), H46.01 (right eye), H46.02 (left eye) and H46.03 (bilateral).

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