E10.349 — Type 1 diabetes mellitus with severe nonproliferative diabetic retinopathy without macular edema
E10.349 is a non-billable header ICD-10-CM code for type 1 diabetes mellitus with severe nonproliferative 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 E10.34 to designate laterality of the disease:

- 2
- left eye
- 3
- bilateral
- 9
- unspecified eye
Risk adjustment
E10.349 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.
