About H35.31

H35.31 is the ICD-10-CM diagnosis code for Nonexudative age-related macular degeneration. It belongs to category H35 (other retinal disorders), block H30-H36 (disorders of choroid and retina) 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 H35.3 (degeneration of macula and posterior pole), H35.31 is specifically for Nonexudative age-related macular degeneration. Related codes cover unspecified macular degeneration (H35.30), Exudative age-related macular degeneration (H35.32), Angioid streaks of macula (H35.33), macular cyst, hole, or pseudohole (H35.34), Cystoid macular degeneration (H35.35), Drusen (degenerative) of macula (H35.36), puckering of macula (H35.37) and toxic maculopathy (H35.38).

Codes in this range require a 7th character: 0 for stage unspecified, 1 for early dry stage, 2 for intermediate dry stage, 3 for advanced atrophic without subfoveal involvement and 4 for advanced atrophic with subfoveal involvement. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2017 (expanded into subcodes).
