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.

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to E09: its own notes plus those printed at Chapter 4. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

On E09 itself
  • 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.-)
From Chapter 4 (E00-E89) Endocrine, nutritional and metabolic diseases applies to 973 codes
  • transitory endocrine and metabolic disorders specific to newborn (P70-P74)

Code First

The underlying condition named in the note is sequenced before this code.

  • poisoning due to drug or toxin, if applicable (T36-T65 with fifth or sixth character 1-4)

Use Additional Code

Add a second code, after this one, to fully describe the condition.

  • code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5)
  • code to identify control using:
  • injectable non-insulin antidiabetic drugs (Z79.85)
  • insulin (Z79.4)
  • oral antidiabetic drugs (Z79.84)
  • oral hypoglycemic drugs (Z79.84)

Notes

General instructions on how these codes are used.

From Chapter 4 (E00-E89) Endocrine, nutritional and metabolic diseases applies to 973 codes
  • All neoplasms, whether functionally active or not, are classified in Chapter 2. Appropriate codes in this chapter (i.e. E05.8, E07.0, E16-E31, E34.-) may be used as additional codes to indicate either functional activity by neoplasms and ectopic endocrine tissue or hyperfunction and hypofunction of endocrine glands associated with neoplasms and other conditions classified elsewhere.

Referenced in Other NotesGuidance

Instructional notes printed at other codes that name E09, its category, or a range that includes it.

Excludes1 4

These codes carry an Excludes1 note naming E09: they are not reported together with it, unless the two conditions are unrelated.

  • E08 Diabetes mellitus due to underlying condition
    drug or chemical induced diabetes mellitus (E09.-)
  • E10 Type 1 diabetes mellitus
    drug or chemical induced diabetes mellitus (E09.-)
  • E11 Type 2 diabetes mellitus
    drug or chemical induced diabetes mellitus (E09.-)
  • E13 Other specified diabetes mellitus
    drug or chemical induced diabetes mellitus (E09.-)

Excludes2 1

These codes carry an Excludes2 note naming E09: its condition is not part of those codes, and both may be reported when the patient has both.

  • E87.0 Hyperosmolality and hypernatremia
    diabetes with hyperosmolarity (E08, E09, E11, E13 with final characters .00 or .01)

Use Additional Code 2

These codes say to use an additional code from the note, and E09 is one of the codes named.

  • O24.8 Other pre-existing diabetes mellitus in pregnancy, childbirth, and the puerperium
    from categories E08, E09 and E13 to further identify any manifestation
  • O24.9 Unspecified diabetes mellitus in pregnancy, childbirth and the puerperium
    from categories E08, E09 and E13 to further identify any manifestation

Patient EducationClinical

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

What is the ICD-10 code for drug or chemical induced diabetes mellitus?

E09 is the ICD-10-CM category for drug or chemical induced diabetes mellitus, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

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.

Can E09 be reported with a code from E08?

Not as a rule. The Excludes1 note on E09 lists "diabetes mellitus due to underlying condition (E08.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).

Does E09 need an additional code?

When the condition applies, yes. The Use Additional Code note reads: code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5); code to identify control using:; injectable non-insulin antidiabetic drugs (Z79.85); insulin (Z79.4); oral antidiabetic drugs (Z79.84); and 1 more listed in the Instructional Notes section. The additional code is reported after E09.
