  • This is the American ICD-10-CM version of E24.0 - other international versions of ICD-10 E24.0 may differ.
Applicable To
  • Overproduction of pituitary ACTH
  • Pituitary-dependent hypercorticalism

    Endocrine, nutritional and metabolic diseases

    Note
    • 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.
    Type 1 Excludes
    • transitory endocrine and metabolic disorders specific to newborn (P70-P74)
    Endocrine, nutritional and metabolic diseases
  • E20-E35
    2020 ICD-10-CM Range E20-E35

    Disorders of other endocrine glands

    Type 1 Excludes
    Disorders of other endocrine glands
  • E24
    ICD-10-CM Diagnosis Code E24

    Cushing's syndrome

      2016 2017 2018 2019 2020 Non-Billable/Non-Specific Code
    Type 1 Excludes
    • congenital adrenal hyperplasia (E25.0)
    Cushing's syndrome
Approximate Synonyms
  • Cushing disease
  • Pituitary dependent hypercortisolism
Clinical Information
  • A disease of the pituitary gland characterized by the excess amount of adrenocorticotropic hormone secreted. This leads to hypersecretion of cortisol (hydrocortisone) by the adrenal glands resulting in cushing syndrome.
ICD-10-CM E24.0 is grouped within Diagnostic Related Group(s) (MS-DRG v37.0):
  • 643 Endocrine disorders with mcc
  • 644 Endocrine disorders with cc
  • 645 Endocrine disorders without cc/mcc
