Question: My pulmonologist injected Xylocaine and Solu-Medrol into a patient's rib cage. How should I code this procedure? Kansas Subscriber Answer: Then report J2001 (Injection, lidocaine HCl for intravenous infusion, 10 mg) for every 10 mg of Xylocaine injected. The correct code for Solu-Medrol depends on the injection amount; report J2920 (Injection, methylprednisolone socium succinate, up to 40 mg) or J2930 (Injection, methylprednisolone sodium succinate, up to 125 mg) as appropriate.
