Question: A patient presented for a superficial axillary lymph node core needle biopsy. The procedure note states the provider performed the biopsy and inserted a soft tissue marker at the same time. Should I use a breast biopsy code for the procedure? Oklahoma Subscriber Answer: No, you shouldn’t use a breast biopsy code for this procedure if the documentation doesn’t include mention of a breast biopsy. While the axillary is near the breast, the CPT® code set includes a code that specifies biopsies performed on the axillary lymph nodes. Instead of choosing a breast biopsy code, you’ll assign 38505 (Biopsy or excision of lymph node(s); by needle, superficial (eg, cervical, inguinal, axillary)) to report the superficial axillary lymph node biopsy and 10035 (Placement of soft tissue localization device(s) (eg, clip, metallic pellet, wire/needle, radioactive seeds), percutaneous, including imaging guidance; first lesion) to report the soft tissue marker placement.
