Surgical exploration
About 35800: Neck exploration without repair
Exploration of the neck, often to investigate a postoperative hematoma or bleeding, is reported when the procedure does not proceed to surgical repair.
This service involves opening or reopening a neck incision to inspect the operative field, commonly when a patient develops a suspected hematoma or bleeding after neck surgery such as carotid endarterectomy. The surgeon examines the area and may evacuate clot while assessing for a source. It is typically performed in an operating room when the clinical concern warrants surgical exploration.
Report this code when the neck is explored and the procedure is not followed by surgical repair. Documentation should identify the reason for exploration, the neck site, operative findings, and whether a repair was performed. The code has a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

35800 billing questions
When is neck exploration reported instead of a neck vessel repair?
Use this code when the neck is explored but the procedure does not proceed to surgical repair. If a vessel is surgically repaired, report the repair service that matches the vessel and operative circumstances.
Can this code be reported for exploration after carotid endarterectomy?
It may describe a return to the operating room to investigate a suspected neck hematoma or bleeding after carotid endarterectomy, provided the procedure does not proceed to surgical repair.
Can the exploration be reported with another procedure in the same session?
When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. The operative record should distinguish the neck exploration from any separately reported procedure.
Should modifier 50 be used when both sides of the neck are explored?
No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.
What documentation supports assistant or co-surgeon reporting?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation, while team surgery is not permitted.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
