Official Description

Sex hormone binding globulin (SHBG)

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 84270 refers to the measurement of sex hormone binding globulin (SHBG) levels through a blood test. SHBG is a glycoprotein that plays a crucial role in the regulation of sex hormones, specifically testosterone and estradiol, by binding to them in the bloodstream. This binding affects the availability of these hormones to tissues and can influence various physiological processes. The measurement of SHBG is often conducted alongside a total testosterone test, identified by CPT® Code 84403, to provide a comprehensive assessment of hormonal balance. In men, low SHBG levels are typically associated with reduced testosterone levels, which can lead to conditions such as infertility and erectile dysfunction. Conversely, in women, elevated SHBG levels may indicate underlying health issues, including amenorrhea, infertility, acne, hirsutism, and polycystic ovarian syndrome (PCOS). The test is performed by obtaining a blood sample through venipuncture, which is a separately reportable procedure. The serum or plasma obtained from the blood sample is then analyzed using a quantitative electrochemiluminescent immunoassay, a sensitive and specific method for measuring SHBG concentrations in the laboratory.

1. Indications

The measurement of sex hormone binding globulin (SHBG) levels is indicated for various clinical scenarios, particularly when assessing hormonal imbalances or related conditions. The following are the specific indications for performing this test:

  • Infertility in Men Low levels of SHBG in men may correlate with decreased testosterone levels, which can contribute to infertility issues.
  • Erectile Dysfunction Men with low SHBG levels may experience erectile dysfunction due to insufficient testosterone availability.
  • Amenorrhea in Women Elevated SHBG levels in women can be associated with amenorrhea, a condition characterized by the absence of menstrual periods.
  • Infertility in Women Women with high SHBG levels may also face infertility challenges, necessitating further evaluation of hormonal status.
  • Acne and Hirsutism Elevated SHBG levels can be linked to conditions that cause acne and hirsutism, which are often symptoms of hormonal imbalance.
  • Polycystic Ovarian Syndrome (PCOS) Women diagnosed with PCOS may exhibit elevated SHBG levels, making this test relevant for diagnosis and management.

2. Procedure

The procedure for measuring sex hormone binding globulin (SHBG) levels involves several key steps, which are outlined below:

  • Step 1: Patient Preparation Prior to the blood draw, the patient may be instructed to avoid certain medications or supplements that could affect hormone levels. It is essential to ensure that the patient is adequately informed about the procedure and any necessary preparations.
  • Step 2: Venipuncture A qualified healthcare professional performs venipuncture to obtain a blood sample. This involves inserting a needle into a vein, typically in the arm, to collect the required volume of blood. The procedure is performed using sterile techniques to minimize the risk of infection.
  • Step 3: Sample Handling Once the blood sample is collected, it is processed to separate the serum or plasma from the cellular components. This step is crucial for accurate testing, as SHBG levels are measured in the serum or plasma.
  • Step 4: Laboratory Analysis The serum or plasma sample is then subjected to quantitative electrochemiluminescent immunoassay, a laboratory technique that allows for the precise measurement of SHBG concentrations. This method is known for its sensitivity and specificity, ensuring reliable results.
  • Step 5: Result Interpretation After the analysis is complete, the results are interpreted by a qualified healthcare professional. The SHBG levels are evaluated in conjunction with other hormone tests, such as total testosterone, to provide a comprehensive understanding of the patient's hormonal status.

3. Post-Procedure

After the procedure, patients may be advised to resume their normal activities, as there are typically no significant restrictions following a blood draw. However, it is common for patients to experience minor discomfort or bruising at the venipuncture site, which usually resolves quickly. The healthcare provider will discuss the results with the patient once they are available, and any necessary follow-up actions or additional testing will be determined based on the findings. It is important for patients to understand the implications of their SHBG levels and how they relate to their overall health and any symptoms they may be experiencing.

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.
GA Waiver of liability statement issued as required by payer policy, individual case
GZ Item or service expected to be denied as not reasonable and necessary
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
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
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.
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.

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.
