How To Use CPT Code 85244

CPT 85244 describes the laboratory test performed to determine the presence of factor VIII related antigen in a patient’s serum. This article will cover the description, procedure, qualifying circumstances, appropriate usage, documentation requirements, billing guidelines, historical information, similar codes and billing examples.

1. What is CPT Code 85244?

CPT 85244 is used to describe a laboratory test that assesses the presence of factor VIII related antigen in a patient’s serum. This test is typically performed by a lab analyst and involves technical steps to determine the presence of the factor VIII related protein using an antigen immunoassay. While this test is not limited to diagnosing a specific condition, it may be ordered by clinicians to diagnose the less common form of hemophilia A associated with a lack of the factor VIII related protein.

2. Official Description

The official description of CPT code 85244 is: ‘Clotting; factor VIII related antigen.’

3. Procedure

1. The lab analyst performs a test to assess the presence of factor VIII related antigen in the patient’s serum.
2. This test involves technical steps, such as an antigen immunoassay, to determine the presence of the factor VIII related protein.
3. The lab analyst performs all necessary technical procedures to complete the test and obtain accurate results.

4. Qualifying circumstances

CPT 85244 may be ordered by clinicians to diagnose the less common form of hemophilia A associated with a lack of the factor VIII related protein. It is important to note that this test is not typically ordered by clinicians and is primarily performed by lab analysts.

5. When to use CPT code 85244

CPT code 85244 should be used when a laboratory test is performed to assess the presence of factor VIII related antigen in a patient’s serum. This test is typically ordered to diagnose the less common form of hemophilia A associated with a lack of the factor VIII related protein.

6. Documentation requirements

To support a claim for CPT 85244, documentation should include:

• Reason for ordering the test, such as suspicion of the less common form of hemophilia A
• Details of the technical steps performed to assess the presence of factor VIII related antigen
• Date and time of the test
• Results of the test
• Signature of the lab analyst performing the test

7. Billing guidelines

When billing for CPT 85244, it is important to ensure that the test is performed by a lab analyst and that the necessary technical steps are followed. Some payers may also separately reimburse for specimen collection using a code such as 36415 for venipuncture.

8. Historical information

CPT 85244 was added to the Current Procedural Terminology system on January 1, 1990. There have been no updates to the code since its addition.

9. Examples

1. A lab analyst performs a test to assess the presence of factor VIII related antigen in a patient’s serum to diagnose the less common form of hemophilia A.
2. A clinician orders a laboratory test to determine the presence of factor VIII related antigen in a patient’s serum, suspecting the less common form of hemophilia A.
3. A lab analyst performs an antigen immunoassay to assess the presence of factor VIII related antigen in a patient’s serum, aiding in the diagnosis of the less common form of hemophilia A.
4. A patient undergoes a laboratory test to determine the presence of factor VIII related antigen in their serum, helping to diagnose the less common form of hemophilia A.
5. A lab analyst performs a test to assess the presence of factor VIII related antigen in a patient’s serum, providing valuable information for the diagnosis of the less common form of hemophilia A.
6. A clinician orders a laboratory test to determine the presence of factor VIII related antigen in a patient’s serum, aiding in the diagnosis of the less common form of hemophilia A.
7. A lab analyst performs an antigen immunoassay to assess the presence of factor VIII related antigen in a patient’s serum, assisting in the diagnosis of the less common form of hemophilia A.
8. A patient undergoes a laboratory test to determine the presence of factor VIII related antigen in their serum, providing valuable information for the diagnosis of the less common form of hemophilia A.
9. A lab analyst performs a test to assess the presence of factor VIII related antigen in a patient’s serum, aiding in the diagnosis of the less common form of hemophilia A.
10. A clinician orders a laboratory test to determine the presence of factor VIII related antigen in a patient’s serum, assisting in the diagnosis of the less common form of hemophilia A.
