The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

  • Use E24.0 for Pituitary-dependent Cushing's disease - BILLABLE CODE

  • Use E24.1 for Nelson's syndrome - BILLABLE CODE

  • Use E24.2 for Drug-induced Cushing's syndrome - BILLABLE CODE

  • Use E24.3 for Ectopic ACTH syndrome - BILLABLE CODE

  • Use E24.4 for Alcohol-induced pseudo-Cushing's syndrome - BILLABLE CODE

  • Use E24.8 for Other Cushing's syndrome - BILLABLE CODE

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.
  • congenital adrenal hyperplasia E25.0

Patient Education


Cushing's Syndrome

Cushing's syndrome is a hormonal disorder. The cause is long-term exposure to too much cortisol, a hormone that your adrenal gland makes. Sometimes, taking synthetic hormone medicine to treat an inflammatory disease leads to Cushing's. Some kinds of tumors produce a hormone that can cause your body to make too much cortisol.

Cushing's syndrome is rare. Some symptoms are:

  • Upper body obesity
  • Thin arms and legs
  • Severe fatigue and muscle weakness
  • High blood pressure
  • High blood sugar
  • Easy bruising

Lab tests can show if you have it and find the cause. Your treatment will depend on why you have too much cortisol. If it is because you have been taking synthetic hormones, a lower dose may control your symptoms. If the cause is a tumor, surgery and other therapies may be needed.
