2025 ICD-10-CM code E13

A form of diabetes not captured by other classifications.This includes diabetes due to genetic defects, post-pancreatectomy, or secondary diabetes.

All neoplasms should be coded in Chapter 2, even if they are functionally active. Codes E05.8, E07.0, E16-E31, and E34.- can be used as additional codes if needed.Do not use this code for diabetes due to autoimmune process (E10.-), due to underlying condition (E08.-), drug or chemical induced (E09.-), gestational (O24.4-), neonatal (P70.2), or type 1 (E10.-).

Medical necessity should be documented based on the patient's individual circumstances and the specific type of diabetes.

Diagnosis and treatment are the responsibility of the healthcare provider. They will consider the patient's symptoms, medical history, and conduct tests like blood glucose and lipid profile checks. Treatment options include non-insulin and insulin therapies, potentially along with surgery depending on complications.

In simple words: This code is used when someone has diabetes, but it's not Type 1 or Type 2. It could be due to genetic problems, surgery, or other medical conditions.

Other specified diabetes mellitus includes: diabetes mellitus due to genetic defects of beta-cell function, diabetes mellitus due to genetic defects in insulin action, postpancreatectomy diabetes mellitus, postprocedural diabetes mellitus, and secondary diabetes mellitus NEC.Use additional code to identify control using: injectable non-insulin antidiabetic drugs (Z79.85), insulin (Z79.4), oral antidiabetic drugs (Z79.84), or oral hypoglycemic drugs (Z79.84).

Example 1: A patient develops diabetes after a pancreatectomy., Genetic testing reveals a defect in insulin action leading to a unique form of diabetes., A patient develops diabetes secondary to another medical condition.

Documentation should specify the type of diabetes, underlying cause (e.g. genetic defect, post-pancreatectomy, etc.), and if applicable, the method of diabetes control (insulin, oral medication).
