Question: California Subscriber Answer: Cardiology practices should report E/M codes (99201-99215) if they administer Coumadin testing in-house and perform a substantial, separate E/M service in-addition to the routine Coumadin clinic visit. When the cardiologist calls the patient to convey test findings, you should consider his phone call included in the test itself or in the E/M service that he billed when the patient presented for testing. Many practices conduct Protime tests with blood they collect using a capillary stick (36416, Collection of capillary blood specimen [e.g., finger, heel, ear stick]) instead of venipuncture (36415, Collection of venous blood by venipuncture). You should check with your nurse to confirm that she collects this blood by venipuncture. Blood collection by finger, heel or ear stick is not payable by Medicare and many other payers.
