Other Cushing's syndrome

This code represents forms of Cushing's syndrome that are not specified as pituitary-dependent (Cushing's disease), adrenal-dependent, or ectopic ACTH syndrome. It encompasses hypercortisolism due to other underlying etiologies or when the specific cause is not yet fully determined but is known not to be one of the more common types.

Use this code when documentation indicates Cushing's syndrome from causes such as iatrogenic (e.g., prolonged corticosteroid use not otherwise specified), food-dependent, or other rare forms of hypercortisolism. It is appropriate when the physician explicitly diagnoses "other Cushing's syndrome" or when the specific etiology of endogenous hypercortisolism does not fit into E24.0, E24.1, or E24.3.

• Do not use this code for Cushing's syndrome due to pituitary-dependent ACTH hypersecretion (Cushing's disease) or adrenal cortical tumor.
• Ensure documentation clearly specifies the "other" nature of the Cushing's syndrome, ruling out more specific types.
• Consider sequencing this code as a primary diagnosis when it is the reason for the encounter, followed by codes for any associated manifestations or complications.
