ICD-10 Code E24 – Cushing’s syndrome (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E24 – Cushing’s syndrome
What it is
E24 identifies Cushing’s syndrome, a disorder caused by prolonged excess cortisol exposure. It may be due to endogenous overproduction or other documented causes; check documentation for the exact etiology.
Clinical signs
Common findings include central weight gain, rounded facies, skin thinning, easy bruising, and proximal muscle weakness. Clinical features vary; refer to documentation and confirm the syndrome is established.
When to use this code
Use E24 when the record clearly documents Cushing’s syndrome, including when the provider names hypercortisolism or a specific Cushing-related disorder. Code the documented condition, not just a single symptom, unless the syndrome is confirmed. If the cause is specified, follow the record and any applicable additional codes.
Do not use for
Do not use E24 for isolated obesity, moon facies, or steroid use without documented Cushing’s syndrome. Check documentation if the chart only suggests possible hypercortisolism.
Coding tip
Verify whether the provider documents the syndrome itself and any stated cause before assigning E24.
