There are new, revised, and deleted codes for 2019. The most influential code sets that could affect your practice are the PICC line placements (36568-36573) and the new FNA biopsy codes (10004-10021). The wRVUs may be lower, but that should not influence your documentation of guidance used with these procedures.
Codes changed along with a reduction in reimbursement. CPT 10022 (RVU 1.88) Fine needle aspiration with imaging guidance was deleted in 2019 but it was replaced with new codes that specified the type of guidance (e.g., ultrasound, fluoro, CT, MR) used. Also, new add-on codes were added for when more than one distinct lesion was treated.
