Orthopedic surgery
About 23174: Humeral head or neck sequestrectomy
Reports operative removal of a sequestrum from the humeral head or surgical neck, typically to address devitalized bone associated with osteomyelitis.
An orthopedic surgeon uses this procedure to remove a sequestrum, a fragment of dead bone, from the humeral head or surgical neck. It is typically performed in an operating room when diseased bone requires operative treatment, such as in a case of chronic bone infection. The operative report should identify the humeral site and describe removal of the sequestrum rather than a broader bone resection or excision of a bone lesion.
Report the code when the documented procedure matches that site and scope; the operative note should support the diagnosis, location, and bone removed. Medicare treats it as major surgery with a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. 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%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

23174 billing questions
When should this code be chosen instead of a proximal humerus partial excision code?
Use this code when the operative work is removal of a sequestrum from the humeral head or surgical neck. A broader removal of proximal humeral bone may point to a different procedure code.
How does this differ from a humeral head resection?
This code describes removal of devitalized bone at the humeral head or surgical neck. A humeral head resection represents a broader resection rather than removal of a sequestrum.
What documentation supports reporting this procedure?
The operative report should identify the humeral head or surgical neck and describe removal of the sequestrum. Documentation should distinguish that work from removal of a bone lesion or a larger bone segment.
What is included in the Medicare global period?
The major-surgery global period includes the day-before preoperative visit and 90 days of related postoperative care.
How are bilateral procedures and other same-session procedures paid?
Bilateral reporting with modifier 50 is paid at 150%. For multiple procedures in the same session, the highest-valued procedure is paid in full and others at 50%.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
