CPT® Code 23331

Deleted

1. Indications

The procedure associated with CPT® Code 23331 is indicated for the removal of deep foreign bodies from the shoulder. This may include:

• Penetrating Foreign Body A foreign object that has entered the shoulder joint through a traumatic wound.
• Implanted Foreign Body An object such as a hemiprosthesis that has been surgically placed in the shoulder joint as part of a previous procedure.

2. Procedure

The procedure for CPT® Code 23331 involves several critical steps to ensure the safe and effective removal of the foreign body from the shoulder joint:

• Step 1: Incision A skin incision is made over the shoulder joint to provide access to the underlying structures. This incision is strategically placed to minimize damage to surrounding tissues.
• Step 2: Dissection The surgeon carefully dissects through the soft tissues, which may include muscles and fascia, to reach the joint capsule. This step is crucial for exposing the joint and ensuring that the foreign body can be accessed.
• Step 3: Joint Exposure Once the joint capsule is exposed, it is opened to allow access to the shoulder joint. The humeral head or prosthesis is then dislocated to facilitate a thorough inspection of the joint structures.
• Step 4: Foreign Body Removal The surgeon identifies the deep foreign body, which may be a penetrating object or an implanted device. If it is a penetrating foreign body, it is grasped and extracted. In the case of an implanted device, such as a hemiprosthesis, it is carefully freed from the humerus or glenoid cavity before removal.
• Step 5: Bone Cement Removal If bone cement is present, it is also removed during this procedure to ensure that the joint is clean and free of any foreign materials.
• Step 6: Smoothing Bony Surfaces After the foreign body and any associated materials are removed, the bony surfaces are smoothed to promote healing and prepare the site for any potential further interventions.
• Step 7: Additional Procedures If necessary, a new prosthesis may be placed in a separately reportable procedure. In cases where infection is present, a drain may be placed, and the soft tissues are closed around the drain to facilitate recovery.

3. Post-Procedure

Post-procedure care following the removal of a deep foreign body from the shoulder typically involves monitoring for signs of infection and ensuring proper healing of the surgical site. Patients may be advised on activity restrictions to allow for adequate recovery. If a drain was placed, it will need to be monitored and managed according to the surgeon's instructions. Follow-up appointments will be necessary to assess the healing process and determine if further interventions, such as the placement of a new prosthesis, are required.
