The more appropriate code for use in spinal surgery, when bone marrow is harvested, is 38220 (Bone marrow; aspiration only). You may report 38220 when the bone marrow is harvested through a separate skin or fascial incision/puncture. Harvest of bone marrow through the same surgical exposure (e.g., from the pedicle) is not separately reported.
