CPT® Code 82024: Adrenocorticotropic Hormone (ACTH)

CPT® Code 82024

CPT® Code 82024 is used to report laboratory measurement of adrenocorticotropic hormone (ACTH) in a patient's specimen. ACTH is a hormone produced by the pituitary gland that stimulates the adrenal glands to produce cortisol and other adrenal hormones.

ACTH testing is commonly used alongside cortisol testing to evaluate the hypothalamic-pituitary-adrenal (HPA) axis and investigate conditions involving abnormal adrenal or pituitary function.

This code represents the laboratory assay, not specimen collection or separate evaluation and management services.

Key Facts About CPT® 82024

  • Service type: Laboratory hormone test
  • Test: Adrenocorticotropic hormone (ACTH)
  • Specimen type: Typically plasma
  • Test purpose: Evaluate pituitary and adrenal function
  • Provider type: Physicians, laboratories, and qualified healthcare professionals

Common clinical indications:

  • Suspected adrenal insufficiency
  • Evaluation of Cushing syndrome
  • Assessment of abnormal cortisol levels
  • Suspected pituitary disorders
  • Evaluation of adrenal or pituitary dysfunction

When to Use CPT® 82024

CPT 82024 is appropriate when:

  • A provider orders ACTH measurement as part of an endocrine evaluation
  • The patient has symptoms or laboratory findings suggesting abnormal adrenal function
  • ACTH is being evaluated alongside cortisol or other endocrine tests
  • Monitoring is clinically appropriate for an established adrenal or pituitary disorder

Examples:

  • Evaluating a patient with suspected adrenal insufficiency
  • Investigating elevated cortisol levels and possible Cushing syndrome
  • Assessing ACTH and cortisol together to help determine whether an abnormality originates from the adrenal glands or pituitary
  • Monitoring an established endocrine disorder

Documentation Requirements

To support CPT 82024 billing, documentation should include:

  • Patient identifiers and date of service
  • Clinical indication for ACTH testing
  • Relevant symptoms, diagnoses, or abnormal laboratory findings
  • Specimen type and collection information
  • ACTH test performed
  • Test result and date reported
  • Ordering provider information

When ACTH is ordered with cortisol or other endocrine tests, documentation should support the clinical rationale for the broader evaluation.

Reimbursement and Coding Considerations

  • CPT 82024 reports the laboratory measurement of ACTH
  • Diagnosis coding should support the medical necessity of endocrine testing
  • ACTH and cortisol are separate laboratory measurements and may be reported separately when both are performed and appropriately documented
  • Coverage and frequency limitations vary by payer and clinical indication
  • Specimen collection may be separately reportable when permitted by payer policy

Always verify payer-specific laboratory and endocrine testing requirements before submitting claims.
