2021 ICD-10-CM Codes for Diabetes mellitus due to underlying condition (E08)

Instructional Notations

Code First Code First
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 underlying condition, such as:
  • congenital rubella P35.0
  • Cushing's syndrome E24
  • cystic fibrosis E84
  • malignant neoplasm C00 C96
  • malnutrition E40 E46
  • pancreatitis and other diseases of the pancreas K85 K86

Use Additional Code Use Additional Code
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.

  • code to identify control using:
  • insulin Z79.4
  • oral antidiabetic drugs Z79.84
  • oral hypoglycemic drugs Z79.84

Type 1 Excludes Type 1 Excludes
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.

  • drug or chemical induced diabetes mellitus E09
  • 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
