What 10006 covers
A clinician uses ultrasound to locate a target and guide a fine needle to collect cells or fluid from an additional lesion. Common targets include thyroid nodules, cervical lymph nodes, and accessible soft-tissue masses. Radiologists, endocrinologists, surgeons, and other clinicians performing image-guided sampling may report the service in office or outpatient settings. This code represents an additional lesion after the first ultrasound-guided lesion in the same session, not additional needle passes into one lesion.
Report 10006 with 10005 for the first lesion, counting each separately sampled additional lesion. Document the site and identity of each target and the use of ultrasound guidance. The CMS add-on rule requires this code to be billed with a primary procedure; it is paid within that procedure’s global period.

10006 billing questions
What primary code must accompany 10006?
Report 10006 with 10005 for the first lesion sampled with ultrasound guidance. It is an add-on code and is not reported by itself.
Does each needle pass count as an additional lesion?
No. The add-on is for each additional distinct lesion, not for repeat passes or samples taken from the same lesion.
Can ultrasound guidance be billed separately?
Ultrasound guidance is part of the FNA service represented by 10005 and 10006. Do not separately report guidance for the same sampling service.
What documentation supports reporting multiple units?
Document the location and identity of each distinct lesion sampled, along with ultrasound guidance. The record should distinguish the additional targets from the first lesion.
When should 10004 be considered instead?
10004 is for an additional lesion sampled without imaging guidance. Use 10006 when ultrasound guides sampling of the additional lesion.
