H47.29Other optic atrophy

H47.29 is the ICD-10-CM diagnosis code for other optic atrophy. 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 H47.2, choose H47.29 (Other optic atrophy) only when documentation doesn't support a more specific option: unspecified optic atrophy (H47.20), primary optic atrophy (H47.21), hereditary optic atrophy (H47.22) and glaucomatous optic atrophy (H47.23).

To report this condition, pick the subcode that matches the documentation: H47.291 (right eye), H47.292 (left eye), H47.293 (bilateral) and H47.299 (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.
