If you're still trying to report G0001, it's time to stop.
In "December's Recipe for Billing Success," we advised you to report G0001 (Routine venipuncture for collection of specimen[s]) for venous blood collection on a Medicare patient, and 36415 (Collection of venous blood by venipuncture) for the same service on a non-Medicare patient (see the December 2004 issue). That advice expired Jan. 1 when CPT 2005 deleted G0001.
Lesson: You should now report 36415 to Medicare for venipuncture services. However, 36416 (Collection of capillary blood specimen [e.g., finger, heel, ear stick]) will remain an invalid code for Medicare.
