CPT Code 23520 refers to the surgical procedure for the open treatment of a proximal humeral fracture, which involves realigning and stabilizing the fractured upper arm bone near the shoulder joint.
When CPT Code 23520 is Used?
This procedure is indicated in specific clinical scenarios.
- Displaced proximal humeral fractures that cannot be treated effectively with non-surgical methods.
- Fractures involving multiple fragments that require surgical intervention for proper alignment.
- Fractures associated with significant displacement or instability of the humeral head.
Symptoms Indicating This Procedure
Patients may present with various symptoms that suggest the need for surgical intervention.
- Severe shoulder pain that limits movement.
- Swelling and bruising around the shoulder area.
- Inability to lift the arm or perform daily activities.
- Deformity or abnormal positioning of the shoulder.
Causes and Risk Factors
Understanding the causes and risk factors can help in prevention and management.
- Traumatic injuries from falls or accidents.
- Osteoporosis, which weakens bones and increases fracture risk.
- Age-related degeneration of bone and joint structures.
- Participation in high-impact sports or activities.
Diagnostic Tests Before Procedure
Several diagnostic tests are essential for confirming the need for surgery.
- X-rays to visualize the fracture and assess displacement.
- CT scans for detailed imaging of complex fractures.
- MRI to evaluate soft tissue damage around the shoulder.
Procedure Description
The open treatment procedure involves several key steps.
- Administer anesthesia to ensure patient comfort.
- Make an incision over the shoulder to access the fractured bone.
- Realign the fractured bone fragments into their proper position.
- Use plates, screws, or other fixation devices to stabilize the fracture.
- Close the incision with sutures and apply a dressing.
