Official Description

Cortisol; free

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

Cortisol is a glucocorticoid, which is a type of steroid hormone produced by the adrenal glands, particularly in response to stress. This hormone plays a crucial role in various bodily functions, including the regulation of blood glucose levels, suppression of the immune system, and the metabolism of fats, proteins, and carbohydrates. The measurement of cortisol levels is significant in diagnosing certain medical conditions. Specifically, elevated cortisol levels may indicate Cushing syndrome, while decreased levels may suggest Addison disease. The CPT® Code 82530 refers to a specific laboratory test that measures free cortisol, also known as hydrocortisone, in urine. This test is typically conducted using a 24-hour urine collection or a random urine sample, which is collected as a separately reportable procedure. The analysis of the urine sample is performed using advanced techniques such as quantitative liquid chromatography-tandem mass spectrometry, ensuring accurate measurement of free cortisol levels in the body.

1. Indications

The cortisol free test (CPT® Code 82530) is indicated for the evaluation of various conditions related to abnormal cortisol levels. The following are the primary indications for performing this test:

  • Cushing syndrome - This condition is characterized by elevated cortisol levels, which can lead to various health issues, including obesity, hypertension, and diabetes.
  • Addison disease - This disorder involves decreased cortisol production, leading to symptoms such as fatigue, weight loss, and low blood pressure.

2. Procedure

The procedure for obtaining a cortisol free test involves several key steps to ensure accurate results. The following outlines the procedural steps:

  • Step 1: Sample Collection - A urine sample is collected for the test. This can be done using either a 24-hour collection method, where all urine produced in a 24-hour period is gathered, or a random urine sample, which can be collected at any time. It is important that the sample collection is performed according to the specified guidelines to ensure the reliability of the test results.
  • Step 2: Laboratory Analysis - Once the urine sample is collected, it is sent to a laboratory for analysis. The laboratory utilizes quantitative liquid chromatography-tandem mass spectrometry, a sophisticated testing method that allows for precise measurement of free cortisol levels in the urine. This technique is essential for differentiating between normal and abnormal cortisol levels.

3. Post-Procedure

After the urine sample has been collected and analyzed, the results will be interpreted by a healthcare professional. Depending on the findings, further diagnostic testing or treatment may be necessary. Patients may be advised to follow up with their physician to discuss the results and any potential implications for their health. It is also important to note that the collection of urine samples should be done with care to avoid contamination, which could affect the accuracy of the test results.

90 Reference (outside) laboratory: when laboratory procedures are performed by a party other than the treating or reporting physician or other qualified health care professional, the procedure may be identified by adding modifier 90 to the usual procedure number.
91 Repeat clinical diagnostic laboratory test: in the course of treatment of the patient, it may be necessary to repeat the same laboratory test on the same day to obtain subsequent (multiple) test results. under these circumstances, the laboratory test performed can be identified by its usual procedure number and the addition of modifier 91. note: this modifier may not be used when tests are rerun to confirm initial results; due to testing problems with specimens or equipment; or for any other reason when a normal, one-time, reportable result is all that is required. this modifier may not be used when other code(s) describe a series of test results (eg, glucose tolerance tests, evocative/suppression testing). this modifier may only be used for laboratory test(s) performed more than once on the same day on the same patient.
GY Item or service statutorily excluded, does not meet the definition of any medicare benefit or, for non-medicare insurers, is not a contract benefit
GA Waiver of liability statement issued as required by payer policy, individual case
Q4 Service for ordering/referring physician qualifies as a service exemption
GX Notice of liability issued, voluntary under payer policy
26 Professional component: certain procedures are a combination of a physician or other qualified health care professional component and a technical component. when the physician or other qualified health care professional component is reported separately, the service may be identified by adding modifier 26 to the usual procedure number.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
GZ Item or service expected to be denied as not reasonable and necessary
PD Diagnostic or related non diagnostic item or service provided in a wholly owned or operated entity to a patient who is admitted as an inpatient within 3 days
XS Separate structure, a service that is distinct because it was performed on a separate organ/structure
