Note : sorry for the inconvenience there is a correction in 1st example: when FNA is performed on seperate lesions same session , same day , same imaging modality , then we should not append 59 modifier for add on code that is + 10006- Fine needle aspiration biopsy, including ultrasound guidance , each addiotional lesion.
please ignore 59 modifier in 1st example
CPT CODING GUIDELINES FOR SURGERY INTEGUMENTARY SYSTEM PART 1
A fine needle aspiration (FNA) biopsy is performed when material is aspirated (to draw fluid by suction from vessel or cavity) with a fine needle and the cells are examined cytologically.
A core needle biopsy is typically performed with a larger bore needle to obtain a core sample of tissue for histopathologic evaluation.
FNA biopsy procedures are performed with or without imaging guidance
Imaging guidance codes are reported once per lesion sampled in a single session.
