E08.31Diabetes mellitus due to underlying condition with unspecified diabetic retinopathy

E08.31 is the ICD-10-CM diagnosis code for diabetes mellitus due to underlying condition with unspecified diabetic retinopathy. It belongs to category E08 (diabetes mellitus due to underlying condition), block E08-E13 (diabetes mellitus) and chapter 4 (endocrine, nutritional and metabolic diseases). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within E08.3, choose E08.31 (unspecified diabetic retinopathy) only when documentation doesn't support a more specific option: mild nonproliferative diabetic retinopathy (E08.32), moderate nonproliferative diabetic retinopathy (E08.33), severe nonproliferative diabetic retinopathy (E08.34), proliferative diabetic retinopathy (E08.35), diabetic cataract (E08.36), diabetic macular edema, resolved following treatment (E08.37) and other diabetic ophthalmic complication (E08.39).

To report this condition, pick the subcode that matches the documentation: E08.311 (with macular edema) and E08.319 (without macular edema).

Code first the underlying condition, such as: congenital rubella (P35.0), Cushing's syndrome (E24.-), cystic fibrosis (E84.-), malignant neoplasm (C00-C96) and 2 more.

Use an additional code to identify control using: injectable non-insulin antidiabetic drugs (Z79.85), insulin (Z79.4), oral antidiabetic drugs (Z79.84) and oral hypoglycemic drugs (Z79.84).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
