About E13.331
E13.331 is the ICD-10-CM diagnosis code for other specified diabetes mellitus with moderate nonproliferative diabetic retinopathy with macular edema. It belongs to category E13 (other specified diabetes mellitus), 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 4 subcodes must be used instead.
Within E13.33 (other specified diabetes mellitus with moderate nonproliferative diabetic retinopathy), E13.331 is specifically for other specified diabetes mellitus with moderate nonproliferative diabetic retinopathy with macular edema. Related codes cover without macular edema (E13.339).
Codes in this range require a 7th character: 1 for right eye, 2 for left eye, 3 for bilateral and 9 for unspecified eye. Use placeholder "X" characters to fill any empty positions before the 7th character.
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 changed in FY2017 (expanded into subcodes).
