E34 is a non-billable ICD-10-CM category code for other endocrine disorders, so it cannot be submitted on claims. Use a more specific code from this category instead, such as E34.00, E34.01, E34.09, and E34.1.

Specific Coding for Other endocrine disordersOverview

Non-specific codes like E34 require more characters. Use one of these billable codes instead:

  • E34.0 for Carcinoid syndrome

  • Use E34.00 for Carcinoid syndrome, unspecified

  • Use E34.01 for Carcinoid heart syndrome

  • Use E34.09 for Other carcinoid syndrome

  • Use E34.1 for Other hypersecretion of intestinal hormones

  • Use E34.2 for Ectopic hormone secretion, not elsewhere classified

  • E34.3 for Short stature due to endocrine disorder

  • Use E34.30 for Short stature due to endocrine disorder, unspecified

  • Use E34.31 for Constitutional short stature

  • E34.32 for Genetic causes of short stature

  • Use E34.39 for Other short stature due to endocrine disorder

  • Use E34.4 for Constitutional tall stature

  • E34.5 for Androgen insensitivity syndrome

  • Use E34.50 for Androgen insensitivity syndrome, unspecified

  • Use E34.51 for Complete androgen insensitivity syndrome

  • Use E34.52 for Partial androgen insensitivity syndrome

  • Use E34.8 for Other specified endocrine disorders

  • Use E34.9 for Endocrine disorder, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to E34: its own notes plus those printed at block E20-E35 and 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 E34 itself
  • pseudohypoparathyroidism (E20.1)
From Block E20-E35 Disorders of other endocrine glands applies to 99 codes
From Chapter 4 (E00-E89) Endocrine, nutritional and metabolic diseases applies to 973 codes
  • transitory endocrine and metabolic disorders specific to newborn (P70-P74)

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.

Code First 1

These codes say to code first a condition named in the note, and E34 is one of the conditions named.

  • G63 Polyneuropathy in diseases classified elsewhere
    endocrine disease, except diabetes (E00-E07, E15-E16, E20-E34) names E20-E34, which includes this code

These notes mention E34.

  • Chapter 4 (E00-E89) Endocrine, nutritional and metabolic diseases
    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.

Patient EducationClinical

Endocrine Diseases

Your endocrine system includes eight major glands throughout your body. These glands make hormones. Hormones are chemical messengers. They travel through your bloodstream to tissues or organs. Hormones work slowly and affect body processes from head to toe. These include:

Questions About E34Overview

What is the ICD-10 code for other endocrine disorders?

E34 is the ICD-10-CM category for other endocrine disorders, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is E34 (Other endocrine disorders) a billable code?

No. This is a category header that groups the codes for other endocrine disorders, and headers cannot be submitted on claims. Claims for other endocrine disorders need a more specific code from this category, such as E34.00, E34.01, and E34.09.

Can E34 be reported with E20.1?

Not as a rule. The Excludes1 note on E34 lists "pseudohypoparathyroidism (E20.1)". 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).
