Billable / specific codeICD-10-CMleft

Excludes2 inherited from the categories above H35.432

peripheral retinal degeneration with retinal break (H33.3-)

Written on H35 — Other retinal disorders

diabetic retinal disorders (E08.311-E08.359, E09.311-E09.359, E10.311-E10.359, E11.311-E11.359, E13.311-E13.359)

Risk adjustment

H35.432 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage
