E08.4Diabetes mellitus due to underlying condition with neurological complications

E08.4 is the ICD-10-CM diagnosis code for diabetes mellitus due to underlying condition with neurological complications. 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 6 subcodes must be used instead.

Related codes cover with hyperosmolarity (E08.0), with ketoacidosis (E08.1), with kidney complications (E08.2), with ophthalmic complications (E08.3), with circulatory complications (E08.5), with other specified complications (E08.6), with unspecified complications (E08.8) and without complications (E08.9).

To report this condition, pick the subcode that matches the documentation: E08.40 (unspecified), E08.41 (mononeuropathy), E08.42 (polyneuropathy), E08.43 ((poly)neuropathy), E08.44 (amyotrophy) and E08.49 (complication).

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).
