What 10035 covers
A physician places a localization marker into a soft-tissue target through the skin so the site can be identified for a later procedure. Devices may include a clip, wire, metallic marker, or radioactive seed. Common targets include a nonpalpable mass or lymph node that a surgeon needs to locate for excision. The service is typically performed by an interventional radiologist or another physician in an imaging suite or operating room. Imaging guidance is included in the placement service.
Report 10035 for the first lesion; use 10036 for each additional lesion. Documentation should identify the target and site, the localization device placed, and the imaging guidance used. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

How to choose
- 10036Soft-tissue localization
- 10035 reports localization of the first soft-tissue lesion; 10036 reports each additional lesion.
- 19285Breast localization
- 19285 is the breast-specific code for percutaneous localization of a first lesion. Use 10035 for a soft-tissue target outside the breast localization code family.
- 10005Ultrasound-guided FNA
- 10005 reports ultrasound-guided fine-needle aspiration sampling of a lesion. 10035 places a localization marker and does not describe aspiration or tissue sampling.
10035 billing questions
When should 10035 be used instead of 10036?
Use 10035 for the first soft-tissue lesion localized during the service. Report 10036 for each additional lesion.
Can imaging guidance be billed separately?
Imaging guidance is included in 10035. Do not report separate guidance for the same marker placement.
Is 10035 appropriate for a breast lesion?
Breast localization has dedicated codes, including 19285 for the first lesion. Use the code family that applies to the breast localization service rather than 10035.
How is bilateral placement reported?
When the service is bilateral, report modifier 50. CMS pays the bilateral procedure at 150%.
What documentation supports 10035?
Document the target and anatomical site, the marker placed, and the imaging guidance used. The record should support that this was localization of the first lesion.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment is allowed only with documentation of medical necessity. CMS does not permit co-surgeon or team-surgery payment for this code.
