What 60100 covers
A clinician obtains thyroid tissue by passing a needle through the skin into a thyroid nodule or other focal abnormality. The procedure is commonly performed by an endocrinologist, radiologist, or surgeon in an office, outpatient department, or imaging suite. This code describes needle tissue biopsy; when the service is specifically fine-needle aspiration, use the applicable FNA code instead.
Report one service for the percutaneous thyroid biopsy and document the target, needle approach, tissue obtained, and any imaging guidance performed. The code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple procedure reduction. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery, and co-surgeon and team-surgery reporting are not permitted.

How to choose
- 10005Ultrasound-guided FNAFirst lesion
- Use 10005 for fine-needle aspiration biopsy with ultrasound guidance. Use 60100 for percutaneous needle tissue biopsy rather than an FNA service.
- 10021Fine needle aspirationFirst lesion, no imaging
- Use 10021 for fine-needle aspiration biopsy without imaging guidance. The distinction is the FNA method, not simply the thyroid site.
- 60200Thyroid surgeryFocal lesion or isthmus
- 60200 describes surgical excision of a thyroid lesion, not percutaneous needle sampling. Choose it when the lesion is removed surgically.
60100 billing questions
How is 60100 different from a thyroid FNA code?
60100 represents percutaneous needle biopsy for tissue sampling. Use the FNA code set when the service is specifically fine-needle aspiration, with the code determined in part by whether imaging guidance is included.
Can imaging guidance be reported separately?
The biopsy code does not describe imaging guidance. If guidance is performed and separately reportable, document the modality, guidance, and needle placement; ultrasound guidance may be reported with 76942 when its requirements are met.
What documentation supports 60100?
Record the thyroid target, percutaneous needle approach, tissue sampling performed, and the specimen submitted. Include the imaging guidance details when guidance is performed.
Does 60100 have a global period?
It has a 0-day global period. Same-day preoperative and postoperative care is included in the procedure.
Can modifier 50 or an assistant-at-surgery modifier be used?
Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery for 60100.
How does Medicare handle other procedures performed in the same session?
The highest-valued procedure is paid in full, and other procedures in the session are subject to the standard multiple procedure reduction. Co-surgeon and team-surgery reporting are not permitted.
