ICD-10 Code E24.9 – Cushing’s syndrome, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E24.9 – Cushing’s syndrome, unspecified
What it is
E24.9 identifies Cushing’s syndrome when documentation confirms the condition but does not specify the cause or type. Use it for excess cortisol syndrome that is recorded without further detail.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include central weight gain, moon facies, striae, easy bruising, proximal weakness, or hypertension, but you should code only what is documented.
When to use this code
Use E24.9 when the provider documents Cushing’s syndrome and does not identify whether it is pituitary, adrenal, ectopic, or drug-induced. It also fits when the record says “Cushing’s syndrome” without additional clarification. If the etiology is known, use the more specific code instead.
Do not use for
Do not use this code for Cushing disease, exogenous steroid use, or other specified forms of hypercortisolism when the record gives a clearer diagnosis. Check documentation.
Coding tip
Query the provider when the note says only “Cushing’s” and the cause is not clear, because specificity may change the code.
