About 23040: Open glenohumeral joint exploration
An open operation on the glenohumeral joint for exploration, drainage, or removal of an intra-articular foreign body, typically performed by an orthopedic surgeon.
This code describes open entry into the glenohumeral joint to inspect the joint, drain it, or remove a foreign body. An orthopedic surgeon may perform it in a hospital or other surgical facility when the treatment requires open access to the shoulder joint, such as for an intra-articular problem that cannot be managed with needle aspiration or a less invasive approach. It is distinct from procedures directed at the acromioclavicular joint, shoulder bursa, or surrounding soft tissues.
Select the code when the operative report supports open joint entry and identifies the purpose, such as exploration, drainage, or foreign-body removal. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. 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% multiple-procedure reduction. For bilateral treatment, 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.

23040 billing questions
How is this code distinguished from 23044?
This code concerns open exploration, drainage, or foreign-body removal in the glenohumeral joint. Code 23044 addresses the acromioclavicular joint.
Can it be reported for drainage of a shoulder abscess?
Use it when the operation enters and treats the glenohumeral joint. Code 23030 is for deep shoulder abscess or hematoma drainage outside that joint.
Does the code describe arthroscopic treatment?
No. It describes an open joint procedure. Diagnostic shoulder arthroscopy is represented by a different code, such as 29805.
What should the operative report document?
Document open entry into the glenohumeral joint and the specific purpose—exploration, drainage, or removal of a foreign body. Identify the treated joint so the service can be distinguished from work on the AC joint, bursa, or surrounding tissues.
How are bilateral procedures and other same-session procedures handled?
Modifier 50 is paid at 150% for bilateral treatment. When other procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard multiple-procedure reduction.
