CPT® Code 85348

1. Indications

The coagulation time test, represented by CPT® Code 85348, is indicated for various clinical scenarios where assessment of the blood's clotting ability is necessary. This test may be performed in the following situations:

• Assessment of Bleeding Disorders This test is crucial for evaluating patients who present with unexplained bleeding or bruising, as it helps identify potential deficiencies in platelet function or other coagulation factors.
• Monitoring Anticoagulant Therapy Patients undergoing treatment with anticoagulants may require regular monitoring of their coagulation status to ensure therapeutic effectiveness and to prevent complications such as excessive bleeding.
• Preoperative Evaluation Prior to surgical procedures, assessing coagulation time can help determine a patient's risk of bleeding, guiding clinical decisions regarding the need for further testing or interventions.
• Evaluation of Liver Function Since the liver produces many coagulation factors, this test can be part of a broader assessment of liver function, particularly in patients with liver disease.

2. Procedure

The procedure for measuring coagulation time using CPT® Code 85348 involves several key steps that ensure accurate results. The following outlines the procedural steps:

• Sample Collection A blood sample is collected from the patient, typically via venipuncture. The sample must be handled carefully to avoid contamination and ensure that the results reflect the patient's true coagulation status.
• Preparation of the Sample The collected blood sample is processed in the laboratory. This may involve the addition of specific reagents that initiate the coagulation process, depending on the method used for the test.
• Measurement of Coagulation Time The laboratory technician monitors the time it takes for the blood sample to form a clot. This is done using specialized equipment that can accurately measure the time interval from the initiation of coagulation until a stable clot is formed.
• Result Interpretation Once the coagulation time is measured, the results are analyzed and interpreted by a qualified healthcare professional. The findings are then documented and reported to the ordering physician for further clinical decision-making.

3. Post-Procedure

After the coagulation time test is completed, there are several considerations for post-procedure care. Patients may be advised to monitor for any signs of bleeding or bruising at the venipuncture site, although complications are rare. The results of the test will typically be communicated to the healthcare provider who ordered the test, and any necessary follow-up actions will be determined based on the findings. If the coagulation time is abnormal, further testing or adjustments to anticoagulant therapy may be warranted. It is essential for healthcare providers to discuss the results with the patient and outline any additional steps that may be required for their care.
