Question: Patient underwent fine-needle aspiration to remove a cluster of cells from a solid mass, subcutaneous layer of the left upper quadrant, abdomen. Computed tomography (CT) imaging guidance for needle placement was performed. Physician palpated the mass, cleansed the area with Betadine solution, and inserted a 22-gauge needle into the solid mass. Approximately 1 cc of tissue was removed. The needle was withdrawn, and a small bandage was placed over the insertion area. 10009 For code 10009, go to CPT index main term Fine Needle Aspiration (FNA) Biopsy, subterm Lesion, and qualifier with CT Guidance. Review codes in the Fine Needle Aspiration (FNA) Biopsy category of the General subsection in the Surgery section. The case study documents "a solid mass" and "computed tomography (CT) imaging," which indicates that one lesion underwent FNA including CT guidance, and provides guidance for code assignment.
