I frequently perform adjacent tissue transfers (CPT 14000, 14001, 14020). When I excise pilonidal disease (CPT 11770, 11771, 11772) and then perform an adjacent tissue transfer, can I report both the excision and the tissue transfer codes, or is only the tissue transfer separately billable?

Additionally, in cases where I excise a malignant lesion (CPT 11604, 11606) and close the defect with an adjacent tissue transfer, my understanding is that only the adjacent tissue transfer code (e.g., 14000) is reportable, and the excision is considered included. Is this correct?
