ICD Code R79.1

ICD code R79.1 is used to indicate an abnormal coagulation profile, which refers to irregularities in the blood's ability to clot properly. This code is typically used when test results show that the blood clotting process is not functioning as expected, which could be due to various underlying conditions or factors affecting the coagulation system.

1. Prolonged Prothrombin Time (PT): Use the ICD code when laboratory tests indicate a prolonged PT, which may suggest a deficiency in clotting factors or the presence of an inhibitor affecting the coagulation cascade.

2. Prolonged Activated Partial Thromboplastin Time (aPTT): Apply the code if the aPTT is extended, indicating potential issues with the intrinsic or common coagulation pathways.

3. Elevated International Normalized Ratio (INR): Utilize the code when the INR is higher than the normal range, often used to monitor patients on anticoagulant therapy like warfarin.

4. Abnormal Thrombin Time (TT): Use the code if the TT is abnormal, which may suggest fibrinogen abnormalities or the presence of thrombin inhibitors.

5. Presence of Coagulation Factor Deficiencies: Apply the code when specific coagulation factor assays reveal deficiencies, such as Factor VIII or Factor IX, which are critical for normal clotting function.

6. Detection of Coagulation Inhibitors: Use the code if laboratory tests identify inhibitors that interfere with normal coagulation, such as lupus anticoagulant or specific factor inhibitors.

7. Abnormal Platelet Function Tests: Utilize the code when platelet function tests, such as platelet aggregation studies, indicate dysfunction, which can contribute to abnormal coagulation profiles.

8. Clinical Symptoms of Bleeding Disorders: Apply the code when patients present with unexplained bruising, frequent nosebleeds, or prolonged bleeding from minor cuts, suggesting an underlying coagulation disorder.

9. Preoperative Screening Results: Use the code if preoperative coagulation screening reveals abnormalities that may increase the risk of bleeding during or after surgery.

10. Monitoring of Anticoagulant Therapy: Utilize the code for patients undergoing anticoagulant therapy who require regular monitoring to ensure therapeutic levels and prevent complications.

For the ICD code R79.1, which indicates an abnormal coagulation profile, the relevant CPT codes that may be applicable for treatment or diagnostic procedures include:

1. 85610 - Prothrombin time (PT); a test to measure how long it takes blood to clot.

2. 85730 - Thromboplastin time, partial (PTT); a test to evaluate the coagulation factors.

3. 85379 - Fibrinogen; a test to measure the level of fibrinogen in the blood.

4. 85384 - Fibrin degradation products (FDP); a test to detect the presence of fibrin degradation products in the blood.

5. 85613 - Thrombin time; a test to measure the time it takes for a clot to form in the plasma of a blood sample.

6. 85390 - Coagulation assessment; a comprehensive evaluation of the coagulation system.

These CPT codes are typically used in conjunction with the ICD code R79.1 to assess and manage abnormal coagulation profiles in patients. It is important for healthcare providers to select the appropriate CPT codes based on the specific tests and procedures performed.
