Question: A patient presents for chemotherapy treatment. The oncologist performs a 30-minute antibiotic infusion, then a 115-minute chemotherapy infusion. Which infusion does the insurer consider initial in this scenario? Florida Subscriber Answer: For coding purposes, payers consider the initial infusion the "main reason" the patient is seeing the oncologist. When you-re coding for multiple substances, administration order takes a back seat to the infusions- importance. In your case, the chemotherapy is the main reason the patient is having infusion therapy. Thus, you should code the chemotherapy infusion first. On the claim, report the following: - 96413 (Chemotherapy administration, intravenous infusion technique; up to 1 hour, single or initial substance/drug) for the first hour of chemotherapy - +96415 (- each additional hour [list separately in addition to code for primary procedure]) for the remaining 55 minutes of chemotherapy - +90767 (Intravenous infusion, for therapy, prophylaxis, or diagnosis; additional sequential infusion, up to one hour [list separately in addition to code for primary procedure]) for the antibiotic infusion. Note: Do not report 96415 for less than 30 minutes of service beyond the first hour. So if the notes indicate that a patient had 75 minutes of chemotherapy, you-d only report 96413. Also, you should not report 90767 for less than 16 minutes of infusion time. -- The answers for You Be the Coder and Reader Questions were reviewed by Cindy C.
