Specific Coding for Other disorders of adrenal glandOverview

Non-specific codes like E27 require more characters. Use one of these billable codes instead:

  • Use E27.0 for Other adrenocortical overactivity

  • Use E27.1 for Primary adrenocortical insufficiency

  • Use E27.2 for Addisonian crisis

  • Use E27.3 for Drug-induced adrenocortical insufficiency

  • E27.4 for Other and unspecified adrenocortical insufficiency

  • Use E27.40 for Unspecified adrenocortical insufficiency

  • Use E27.49 for Other adrenocortical insufficiency

  • Use E27.5 for Adrenomedullary hyperfunction

  • Use E27.8 for Other specified disorders of adrenal gland

  • Use E27.9 for Disorder of adrenal gland, unspecified

Patient EducationClinical

Adrenal Gland Disorders

Your adrenal glands are two small organs that sit on top of each kidney. The adrenal glands make different types of hormones you need to stay alive and healthy. Hormones are chemicals that travel in your bloodstream and control how different parts of your body work.

Questions About E27Overview

What is the ICD-10 code for other disorders of adrenal gland?

E27 is the ICD-10-CM category for other disorders of adrenal gland, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is E27 (Other disorders of adrenal gland) a billable code?

No. This is a category header that groups the codes for other disorders of adrenal gland, and headers cannot be submitted on claims. Claims for other disorders of adrenal gland need a more specific code from this category, such as E27.0, E27.1, and E27.2.

Can E27 be reported with N64.3?

Not as a rule. The Excludes1 note at block E20-E35, which applies to E27, lists "galactorrhea (N64.3)". 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).
