CPT code 23472 is a medical billing code used by healthcare providers to report total shoulder arthroplasty procedures. This surgical procedure involves replacing both components of the glenohumeral joint with prosthetic implants.
The code 23472 applies when orthopedic surgeons perform comprehensive shoulder joint replacement, addressing severe joint damage that cannot be managed with conservative treatments or less invasive surgical options.
CPT Code 23472 Description
“Arthroplasty, glenohumeral joint; total shoulder (glenoid and proximal humeral replacement).”
The procedure involves complete replacement of both the glenoid (shoulder socket) and the proximal humeral head (ball portion). The orthopedic surgeon removes damaged articular surfaces and installs prosthetic components designed to restore shoulder function and reduce pain.
This is a major orthopedic procedure requiring significant surgical expertise, involving bone preparation, proper implant sizing and positioning, soft tissue balancing, and secure component fixation.
Is CPT Code 23472 Inpatient or Outpatient?
CPT code 23472 is primarily performed as an inpatient procedure. Most healthcare facilities classify this as an inpatient surgery for the following clinical reasons:
- Complex surgical procedure requiring 2-4 hours of operative time
- Need for immediate postoperative monitoring and pain management
- Risk of complications requiring hospital-level care
- Early physical therapy initiation within 24 hours post-surgery
- Standard hospital stay of 1-3 days
While some ambulatory surgery centers may perform this procedure on an outpatient basis for carefully selected patients, the majority of payers and facilities maintain inpatient status for CPT code 23472. Providers should verify specific payer policies and facility capabilities before scheduling.
Scenarios Where CPT Code 23472 is Applicable
Healthcare providers should use CPT code 23472 in the following clinical scenarios:
Scenario 1: Advanced Glenohumeral Arthritis
A 68-year-old patient presents with end-stage osteoarthritis of the shoulder with bone-on-bone contact visible on imaging. Conservative management including NSAIDs, corticosteroid injections, and physical therapy have failed to provide adequate relief. Radiographs show complete loss of joint space, osteophyte formation, and subchondral sclerosis. Total shoulder arthroplasty is indicated and would be coded as 23472.
Scenario 2: Post-Traumatic Joint Destruction
A 55-year-old patient sustained a complex proximal humerus fracture in a motor vehicle accident. Despite initial ORIF, the patient developed post-traumatic arthritis with significant joint surface irregularity and chronic pain limiting daily activities. After failed conservative treatment, conversion to total shoulder arthroplasty is recommended. This procedure is reported using CPT code 23472.
Scenario 3: Failed Previous Arthroplasty
A patient who underwent hemiarthroplasty five years ago now presents with glenoid erosion and persistent pain. The humeral component remains well-fixed, but conversion to total shoulder arthroplasty with glenoid component addition is necessary. While this involves revision components, if converting from hemi to total, CPT 23472 may apply (though providers should also consider 23473 for revision scenarios).
Scenario 4: Avascular Necrosis
A 52-year-old patient with a history of long-term corticosteroid use presents with humeral head collapse secondary to avascular necrosis. MRI confirms extensive bone necrosis with joint involvement. The glenoid also shows degenerative changes. Total shoulder replacement is the appropriate treatment, coded as 23472.
CPT Code 23472 Reimbursement
Reimbursement for CPT code 23472 varies based on payer type, geographic location, and facility setting:
Medicare Reimbursement (2025-2026 rates):
- Physician/surgeon fee: Approximately $1,200-$1,500 (non-facility rate)
- Facility fee: $15,000-$25,000 depending on MS-DRG assignment
- Total episode reimbursement: $20,000-$35,000 including all components
- Payment rates vary by Medicare Administrative Contractor (MAC) region
Commercial Payer Reimbursement:
- Generally 120-200% of Medicare rates
- Depends on specific contracts and negotiated fee schedules
- Prior authorization requirements are common
- Medical necessity review is standard
Factors Affecting Reimbursement Rate
The reimbursement rates for the CPT code 23472 are not the same. The rates depend on:
Geographic location
Urban facilities typically receive higher reimbursement
Facility type
Hospital outpatient vs. inpatient vs. ASC rates differ significantly
Payer mix
Medicare, Medicaid, and commercial insurance pay differently
Contract negotiations
Provider-specific agreements with payers
Medical necessity documentation
Quality of supporting clinical documentation
Comorbidities
Patient complexity affecting DRG assignment
Modifiers Used CPT Code 23472
Modifiers provide additional information about the medical procedure and affect reimbursement. Common modifiers for CPT code 23472 include:
Modifier 50: Bilateral Procedure
Apply when performing total shoulder arthroplasty on both shoulders during the same operative session. This is uncommon but may occur in select cases. Reimbursement is typically 150% of the single-procedure rate.
Modifier RT (Right) or LT (Left)
Required by most payers to specify laterality. Use RT for right shoulder procedures and LT for left shoulder procedures. Failure to include laterality modifiers can result in claim denials.
Modifier 22: Increased Procedural Services
Use when the procedure requires significantly greater work than typical cases. Examples include extensive scarring from multiple previous surgeries, severe bone loss requiring grafting, or unusual patient anatomy. Requires detailed operative report documentation justifying additional complexity. Typically increases reimbursement by 20-30% when approved.
Modifier 51: Multiple Procedures
Apply when performing additional procedures during the same operative session. The secondary procedure typically reimburses at 50% of the usual rate.
Modifier 78: Unplanned Return to Operating Room
Use if the patient requires reoperation during the global period for a complication related to the initial procedure. Reimbursement is typically 70% of the base rate.
Modifier 79: Unrelated Procedure During Global Period
Apply if performing a different procedure during the 90-day global period that is not related to the original shoulder arthroplasty.
Modifier 80/81/82: Assistant Surgeon
Use when an assistant surgeon participates. Payment is typically 16-20% of the primary surgeon’s fee.

Frequently Asked Questions (FAQs)
The answers to your questions are here:
Is CPT Code 23472 an Inpatient Only Code?
CPT code 23472 is not designated as an “inpatient only” procedure on Medicare’s Inpatient Only (IPO) list. However, it is predominantly performed in the inpatient setting due to the complexity of the procedure, postoperative monitoring requirements, and pain management needs.
Can CPT Code 23472 and 23430 Be Billed Together?
No, CPT codes 23472 and 23430 should not be billed together for the same shoulder during the same operative session. CPT 23472 represents total shoulder arthroplasty (glenoid and humeral component replacement), while CPT 23430 represents hemiarthroplasty (humeral component only). These are mutually exclusive procedures.
What is the Global Period for CPT Code 23472?
CPT code 23472 carries a 90-day global period under Medicare guidelines. This means routine postoperative care for 90 days following surgery is included in the procedure’s reimbursement and should not be billed separately. The global period includes the surgery day, normal postoperative visits, and management of typical recovery.
What ICD-10 Codes Support Medical Necessity for CPT 23472?
Common diagnosis codes that support medical necessity for total shoulder arthroplasty include:
- M19.011/M19.012: Primary osteoarthritis of shoulder (right/left)
- M12.511/M12.512: Traumatic arthropathy of shoulder
- M87.021/M87.022: Idiopathic aseptic necrosis of humerus
- S42.291/S42.292: Other fracture of upper end of humerus (with sequelae)
- M16.0: Inflammatory polyarthropathy affecting shoulder
How Do You Handle Revision Cases vs. Primary Arthroplasty?
Primary total shoulder arthroplasty is coded as 23472. Revision of a previous total shoulder replacement should be coded as 23473 (revision of total shoulder arthroplasty). If converting from hemiarthroplasty to total shoulder arthroplasty, coding depends on whether components are being revised or simply added. Consult current CPT coding guidelines and payer policies, as this can be a gray area. Always document clearly in the operative report whether this is a true revision with component removal or a conversion procedure.
What Are Bundled Services That Cannot Be Billed Separately?
Services included in CPT 23472 that should not be billed separately include:
- Surgical approach and exposure
- Wound closure
- Local anesthesia administration
- Routine postoperative care during 90-day global period
- Minor complications managed without return to OR
- Postoperative pain management (first 24 hours)
- Application of surgical dressings
Attempting to bill these separately may result in claim denials or audit findings.
