What 10009 covers

A clinician advances a fine needle into a lesion while using CT images to plan and guide sampling. The needle collects cells or fluid for cytologic evaluation rather than a core of tissue. Radiologists and interventional radiologists commonly perform this service for lesions that need image-guided access, such as a lung or deep soft-tissue mass, in an outpatient imaging department or hospital setting.

Report 10009 for the first lesion sampled with CT guidance. For another distinct lesion sampled during the same session with CT guidance, use the applicable additional-lesion code rather than reporting another first-lesion service. The record should identify the target lesion or site, CT guidance, and the aspiration sampling performed. CT guidance is part of this service; cytology interpretation is a separate service when performed and appropriately reported. Under the standard multiple procedure reduction, the highest-valued procedure in the same session is paid in full and other procedures are paid at 50%.
