2026 ICD-10-CM Diagnosis Code E09Drug or chemical induced diabetes mellitus
E09 is a non-billable ICD-10-CM category code for drug or chemical induced diabetes mellitus, so it cannot be submitted on claims. Use a more specific code from this category instead, such as E09.00, E09.01, E09.10, and E09.11.

Coding GuidelinesGuidance
The diabetes mellitus codes are combination codes that include the type of diabetes mellitus, the body system affected, and the complications affecting that body system. As many codes within a particular category as are necessary to describe all of the complications of the disease may be used. They should be sequenced based on the reason for a particular encounter. Assign as many codes from categories E08 - E13 as needed to identify all of the associated conditions that the patient has.

Tabular List NotesGuidance
Coding notes and annotation back-references applicable to this code.
Code First
Use Additional Code
Type 1 Excludes
- diabetes mellitus due to underlying condition E08
- gestational diabetes O24.4
- neonatal diabetes mellitus P70.2
- postpancreatectomy diabetes mellitus E13
- postprocedural diabetes mellitus E13
- secondary diabetes mellitus NEC E13
- type 1 diabetes mellitus E10
- type 2 diabetes mellitus E11
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Diabetes
Diabetes, also known as diabetes mellitus, is a disease in which your blood glucose, or blood sugar, levels are too high. Glucose is your body's main source of energy. Your body can make glucose, but it also comes from the food you eat. Insulin is a hormone made by your pancreas.

Questions About E09Overview
Is E09 (Drug or chemical induced diabetes mellitus) a billable code?
No. This is a category header that groups the codes for drug or chemical induced diabetes mellitus, and headers cannot be submitted on claims. Claims for drug or chemical induced diabetes mellitus need a more specific code from this category, such as E09.00, E09.01, and E09.10.
