E10.359 — Type 1 diabetes mellitus with proliferative diabetic retinopathy without macular edema
E10.359 is a non-billable header ICD-10-CM code for type 1 diabetes mellitus with proliferative diabetic retinopathy without macular edema. It cannot be billed on its own: choose one of the more specific child codes below. This code also requires a 7th character before it is complete.
This code requires a 7th character
One of the following 7th characters is to be assigned to codes in subcategory E10.35 to designate laterality of the disease:
- 1
- right eye
- 2
- left eye
- 3
- bilateral
- 9
- unspecified eye
Risk adjustment
E10.359 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.
How E10.359 is indexed
Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to E10.359.
