What Is CPT Code 274?
CPT (Current Procedural Terminology) Code 274 refers to a category of surgical procedures performed on the knee joint. These procedures are typically related to arthroplasty (joint replacement), ligament repairs, or reconstructive surgeries. The American Medical Association (AMA) maintains these codes to standardize medical billing and ensure accurate documentation.
CPT Code 274 is often associated with total knee arthroplasty (TKA), partial knee replacements, and other complex knee surgeries. Medical professionals, insurance companies, and healthcare administrators rely on these codes for reimbursement and procedural tracking.
Why Is CPT Code 274 Important?
-
Ensures accurate billing for knee surgeries.
-
Helps track surgical trends and outcomes.
-
Facilitates insurance claims and approvals.

CPT Code 274 Knee: Procedures and Applications
CPT Code 274 covers several knee-related surgical interventions, primarily focusing on joint repair and replacement. Below are some of the most common procedures under this code:
1. Total Knee Arthroplasty (TKA) – CPT 27447
Total knee replacement (TKR) is one of the most frequently performed orthopedic surgeries. It involves removing damaged cartilage and bone and replacing them with metal or plastic prosthetic components.
Indications for TKA:
-
Severe osteoarthritis
-
Rheumatoid arthritis
-
Post-traumatic arthritis
-
Chronic knee pain unresponsive to conservative treatments
2. Revision of Total Knee Arthroplasty – CPT 27487
When an initial knee replacement fails due to infection, loosening, or wear, a revision surgery is required. This procedure is more complex and involves removing and replacing the original implant.
3. Unicompartmental Knee Arthroplasty (Partial Knee Replacement) – CPT 27446
Unlike a total knee replacement, this procedure only replaces the damaged compartment of the knee (medial, lateral, or patellofemoral). It’s less invasive with a faster recovery time.
4. Other Knee Reconstruction Procedures
-
Osteotomy (CPT 27450): Realigning bones to relieve pressure on the knee joint.
-
Ligament Reconstruction (CPT 27427): Repairing torn ligaments like the ACL or PCL.
Common Knee Procedures Under CPT Code 274
| CPT Code | Procedure | Description |
|---|---|---|
| 27447 | Total Knee Arthroplasty (TKA) | Full knee replacement with prosthetic components |
| 27487 | Revision TKA | Replacement of a failed knee implant |
| 27446 | Unicompartmental Knee Arthroplasty | Partial knee replacement (one compartment) |
| 27427 | Ligament Reconstruction | Repair of ACL, PCL, or other ligaments |
| 27450 | Osteotomy | Bone realignment to reduce joint stress |
Who Performs CPT Code 274 Procedures?
These surgeries are performed by orthopedic surgeons specializing in joint reconstruction. Patients are typically referred by:
-
Primary care physicians
-
Rheumatologists (for arthritis-related cases)
-
Sports medicine specialists (for ligament injuries)
Pre-Surgical Evaluation
Before surgery, patients undergo:
-
X-rays & MRI scans
-
Blood tests (to rule out infections)
-
Physical therapy assessments
Recovery and Rehabilitation After CPT 274 Procedures
Recovery varies based on the type of surgery:
Total Knee Replacement (TKA) Recovery Timeline
-
Hospital Stay: 1–3 days
-
Physical Therapy: Begins within 24 hours
-
Full Recovery: 3–6 months
Partial Knee Replacement Recovery
-
Faster healing (6–12 weeks) due to less tissue disruption.
Rehabilitation Tips
-
Follow prescribed physical therapy
-
Use assistive devices (walker/cane)
-
Avoid high-impact activities during early recovery
Insurance and Billing Considerations
Most insurance plans (Medicare, Medicaid, private insurers) cover knee replacement surgeries if medically necessary. Key factors affecting approval:
-
Severity of arthritis (confirmed via imaging)
-
Failed conservative treatments (medications, injections, PT)
-
Surgeon’s documentation
Cost Estimates
-
Total Knee Replacement: $30,000–$50,000 (without complications)
-
Partial Knee Replacement: $20,000–$35,000
FAQs About CPT Code 274
1. What is the difference between CPT 27447 and 27487?
-
27447 = First-time total knee replacement.
-
27487 = Revision surgery for a failed implant.
2. How long does a knee replacement last?
Most implants last 15–20 years, depending on activity levels and weight.
3. Is physical therapy mandatory after surgery?
Yes, PT is crucial for restoring mobility and strength.
4. Can I walk after knee replacement surgery?
Patients typically walk with assistance within 24 hours.
5. What are the risks of knee replacement surgery?
Possible complications include infection, blood clots, implant loosening, or nerve damage.
Conclusion
CPT Code 274 encompasses key knee surgeries, including total and partial replacements, revisions, and ligament repairs. These procedures restore mobility and reduce pain for patients with severe joint damage. Proper pre-surgical evaluation, skilled surgeons, and post-op rehab are critical for success. Always consult an orthopedic specialist to determine the best treatment plan.
