Official Description

Arthrotomy, glenohumeral joint, including exploration, drainage, or removal of foreign body

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The glenohumeral joint, commonly referred to as the shoulder joint, is a critical component of the shoulder's anatomy, characterized as a shallow ball-and-socket joint. It is formed by the articulation of the glenoid fossa of the scapula and the head of the humerus, allowing for a wide range of motion in the arm. The procedure described by CPT® Code 23040 involves an arthrotomy of the glenohumeral joint, which is an open surgical intervention aimed at exploring, draining, or removing foreign bodies from the joint. This procedure is typically indicated in cases where there is suspicion of infection, accumulation of fluid, or the presence of foreign material within the joint space. The surgical approach begins with an incision over the deltoid and pectoral muscles, followed by careful dissection to access the joint capsule. Once the joint is exposed, the surgeon can perform necessary interventions such as drainage of infected material or removal of foreign bodies, ensuring the joint is thoroughly cleaned and flushed to promote healing. This procedure is essential for restoring function and alleviating pain associated with various shoulder conditions.

1. Indications

Arthrotomy of the glenohumeral joint, as described by CPT® Code 23040, is indicated for several specific conditions and symptoms that may affect the joint. These include:

  • Infection: Presence of an infection within the joint, which may manifest as swelling, pain, and fever.
  • Fluid Accumulation: Accumulation of fluid, blood, or purulent material within the joint space that requires drainage to alleviate pressure and prevent further complications.
  • Foreign Body Presence: The presence of foreign bodies within the joint that may cause pain, inflammation, or mechanical obstruction, necessitating their removal.

2. Procedure

The procedure for arthrotomy of the glenohumeral joint involves several critical steps to ensure effective exploration and treatment of the joint. The steps are as follows:

  • Step 1: An anterior approach is utilized, beginning with a skin incision made over the deltoid and pectoral muscles. This incision allows access to the underlying structures of the shoulder.
  • Step 2: The deltoid and pectoral muscles are carefully divided to expose the underlying anatomical structures. The subscapularis tendon is then split to gain access to the glenohumeral joint capsule.
  • Step 3: Once the joint capsule is exposed, it is incised to allow for direct exploration of the glenohumeral joint. This step is crucial for assessing the condition of the joint and identifying any pathological changes.
  • Step 4: If an infection is present, the surgeon will drain any fluid, blood, or purulent material from the joint. This is essential for reducing inflammation and preventing further complications.
  • Step 5: Any loculated fluid collections within the joint are broken up using blunt dissection, facilitating thorough drainage and cleaning of the joint space.
  • Step 6: The joint is then flushed with sterile saline or an antibiotic solution using pulsed lavage. This step helps to clear debris and contaminants from the joint, promoting a clean environment for healing.
  • Step 7: If a foreign body is identified within the joint, it is located and removed to alleviate any obstruction or irritation it may be causing.
  • Step 8: After completing the necessary interventions, drains are placed to allow for continued drainage of any residual fluid. The incision is then closed around the drains to facilitate healing.

3. Post-Procedure

Post-procedure care following an arthrotomy of the glenohumeral joint involves monitoring for signs of infection, managing pain, and ensuring proper drainage through the placed drains. Patients may be advised to limit movement of the shoulder to promote healing and prevent complications. Follow-up appointments are essential to assess the recovery process and to remove drains as necessary. Rehabilitation may be initiated based on the surgeon's recommendations to restore function and strength to the shoulder joint.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
AS Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery
