How To Use CPT Code 0021U

CPT 0021U describes a proprietary laboratory analysis (PLA) test for the detection of eight autoantibodies related to prostate cancer. This article will cover the official description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, and examples.

1. What is CPT Code 0021U?

CPT 0021U is a specific code that represents a proprietary laboratory analysis (PLA) test. This test is designed to detect eight autoantibodies associated with prostate cancer. It is used to provide additional information alongside traditional prostate tests, such as prostate-specific antigen (PSA), to help determine the risk of a patient having prostate cancer.

2. Official Description

The official description of CPT code 0021U is a bit technical. It refers to the test as an immunoassay and flow cytometry serum test that detects eight autoantibodies. These autoantibodies include ARF 6, NKX3-1, 5′-UTR-BMI1, CEP 164, 3′-UTR-Ropporin, Desmocollin, AURKAIP-1, and CSNK2A2. The test also utilizes an algorithm to report a risk score for prostate cancer.

3. Procedure

1. The procedure for CPT code 0021U involves testing a patient’s serum for the presence of eight specific autoantibodies.
2. The test utilizes a multiplex immunoassay and flow cytometry technique to detect and quantify the autoantibodies.
3. An algorithmic analysis is then applied to the results, which generates a risk score for prostate cancer.
4. This risk score provides additional information to clinicians, helping them assess the likelihood of a patient having prostate cancer.

4. Qualifying circumstances

CPT code 0021U is used for patients who require additional information to evaluate their risk of prostate cancer. It is not limited to testing for a specific condition, but rather provides valuable insights alongside other diagnostic tests. Clinicians may order this test when they need more information to define the risk of a patient having prostate cancer.

5. When to use CPT code 0021U

CPT code 0021U should be used when a clinician wants to assess the risk of prostate cancer in a patient. It is typically used alongside other prostate tests, such as PSA, to provide a more comprehensive evaluation. This code should not be used for any other purpose or with any other CPT codes.

6. Documentation requirements

When reporting CPT code 0021U, clinicians must ensure that the following documentation is included:

• Indication of why the test was ordered and the need for additional information
• Results of the multiplex immunoassay and flow cytometry serum test
• Details of the algorithmic analysis used to generate the risk score
• Any other relevant patient information that influenced the interpretation of the test results

7. Billing guidelines

When billing for CPT code 0021U, it is important to remember that this is a proprietary laboratory analysis (PLA) test. Therefore, it should only be reported for the specific test described above, and not with any other CPT codes. Clinicians should follow the usual billing guidelines for laboratory/pathology tests and ensure that the test is performed on human specimens requested by the clinical lab offering the test.

8. Historical information

CPT code 0021U was added to the Current Procedural Terminology system on October 1, 2017. Since then, there have been no updates or changes to the code.

9. Examples

1. A clinician orders CPT code 0021U to assess the risk of prostate cancer in a patient with elevated PSA levels.
2. A patient with a family history of prostate cancer undergoes CPT code 0021U to obtain a comprehensive evaluation of their risk.
3. A clinician uses CPT code 0021U to provide additional information for a patient with inconclusive results from other prostate tests.
4. A patient with persistent prostate-related symptoms undergoes CPT code 0021U to aid in the diagnosis and risk assessment of prostate cancer.
5. A clinician orders CPT code 0021U to monitor the progression or regression of prostate cancer in a patient undergoing treatment.
6. A patient with a previous history of prostate cancer undergoes CPT code 0021U to assess the risk of recurrence.
7. A clinician uses CPT code 0021U to evaluate the risk of prostate cancer in a patient with an abnormal digital rectal examination (DRE).
8. A patient with a high-risk profile for prostate cancer undergoes CPT code 0021U to obtain a more comprehensive assessment of their risk.
9. A clinician orders CPT code 0021U to provide additional information for a patient with conflicting results from other prostate tests.
10. A patient with persistent prostate-related symptoms undergoes CPT code 0021U to aid in the diagnosis and risk assessment of prostate cancer.
