What 38724 covers
A modified radical neck dissection removes cervical lymph-node tissue while preserving one or more nonlymphatic structures that would be sacrificed in a more extensive operation, such as the spinal accessory nerve, internal jugular vein, or sternocleidomastoid muscle. Head and neck surgeons commonly perform it in a hospital operating room for cervical nodal metastases from cancers such as oral cavity, oropharyngeal, laryngeal, or thyroid malignancies. The operative report should establish the dissection performed and identify preserved structures when relevant.
Select this code from the actual operative extent and technique, not simply the cancer diagnosis or the number of positive nodes. Report the neck dissection separately from other procedures only when supported as a distinct service. This major surgery has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

How to choose
- 38720Neck node removal
- 38724 describes a modified radical dissection that preserves selected nonlymphatic structures. Use 38720 when the documented cervical lymphadenectomy has a different, more extensive operative plan.
- 38700Neck lymphadenectomy
- 38700 is for suprahyoid lymphadenectomy, a more limited neck-node procedure. It is not the code for a modified radical cervical dissection.
- 38792Sentinel node injection
- 38792 reports injection of tracer to help identify a sentinel node. It does not report removal of cervical lymph-node tissue by modified radical dissection.
38724 billing questions
How does 38724 differ from 38720?
Use 38724 for a modified radical neck dissection that preserves one or more nonlymphatic structures. Choose 38720 when the operative approach is a complete cervical lymphadenectomy of a different extent.
Does 38724 include the primary tumor resection?
The code describes the cervical lymphadenectomy, not the primary tumor operation. Report another procedure only when the operative documentation supports it as a distinct service.
How is bilateral neck dissection reported?
For bilateral performance, report modifier 50; CMS pays the bilateral procedure at 150%. The operative record should document dissection on both sides.
What documentation supports 38724?
Document the cervical nodal dissection performed, its extent, and the nonlymphatic structures preserved. The operative details should support a modified radical dissection rather than a more limited or different neck procedure.
How does the multiple-procedure reduction affect 38724?
When multiple procedures are performed in the same session, CMS pays the highest-valued procedure in full and the others at 50%. The neck dissection's rank depends on the values of the procedures reported for that session.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
