About E08
E08 is the ICD-10-CM diagnosis code for diabetes mellitus due to underlying condition. It belongs to 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 9 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: E08.0 (with hyperosmolarity), E08.1 (with ketoacidosis), E08.2 (with kidney complications), E08.3 (with ophthalmic complications), E08.4 (with neurological complications), E08.5 (with circulatory complications), E08.6 (with other specified complications), E08.8 (with unspecified complications) and 1 more.
Don't report E08 together with the conditions in its Excludes1 note: drug or chemical induced diabetes mellitus (E09.-), gestational diabetes (O24.4-), neonatal diabetes mellitus (P70.2), postpancreatectomy diabetes mellitus (E13.-) and 4 more.
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.
