Orthopedic surgery
About 23470: Shoulder hemiarthroplasty
Shoulder hemiarthroplasty replaces the humeral joint surface while retaining the native glenoid, typically for selected cases of shoulder arthritis or humeral head damage.
An orthopedic surgeon performs this operation to replace the humeral side of the glenohumeral joint while leaving the patient’s natural glenoid in place. It may be selected for severe shoulder arthritis or substantial humeral head damage when the surgeon plans a hemiarthroplasty rather than replacement of both joint surfaces. The procedure is generally performed in an operating room, with the operative report documenting the condition treated and the components replaced or retained.
Report the code for the hemiarthroplasty, not for a total shoulder replacement or revision of an existing prosthesis. CMS assigns a 90-day global period, which includes 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 other procedures are subject to the standard 50% reduction. 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 payment is not permitted.

This code represents replacement of the humeral side while retaining the native glenoid. Report 23472 when the operation replaces both sides of the shoulder joint.
What documentation supports hemiarthroplasty rather than total shoulder replacement?
The operative report should establish the shoulder condition treated and identify that the humeral joint surface was replaced while the native glenoid was retained.
Does the 90-day global period include postoperative visits?
Yes. CMS includes the day-before preoperative visit and 90 days of related postoperative care in the global period.
How is bilateral hemiarthroplasty handled?
When the procedure is performed bilaterally, CMS pays the service reported with modifier 50 at 150%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery payment is not permitted.
What happens when another procedure is performed during the same session?
