S42.252P Displaced fracture of greater tuberosity of left humerus, subsequent encounter for fracture with malunion

Name of the Condition

• Displaced fracture of greater tuberosity of left humerus, subsequent encounter for fracture with malunion (ICD-10 Code: S42.252P)

Summary

This condition involves a displaced fracture of the greater tuberosity, a bony prominence on the upper end of the left humerus (upper arm bone) near the shoulder joint. The fracture has healed with malunion, meaning the bone fragments have united in an abnormal position. This is a subsequent encounter for treatment, indicating ongoing care for the healing fracture. Malunion may affect shoulder function due to the greater tuberosity’s role as a muscle and ligament attachment site.

Causes

Typically results from direct trauma to the shoulder, such as a fall onto the shoulder, a direct blow, or forceful muscle contraction (e.g., during sports or lifting). The malunion occurs during the healing process when the fractured bone fragments align improperly.

Risk Factors

• Participation in contact sports or activities with a high risk of shoulder injury.
• Osteoporosis or weakened bone density, which increases susceptibility to fractures and malunion.
• Advanced age, which may reduce bone integrity and healing capacity.
• Previous shoulder injuries or conditions that compromise bone strength.

Symptoms

• Persistent pain localized to the shoulder or upper arm.
• Swelling, bruising, and tenderness over the fracture site.
• Difficulty moving the shoulder or lifting the arm.
• Possible visible deformity or prominence at the shoulder.
• Reduced range of motion or functional impairment.

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays or CT scans, to evaluate the fracture’s alignment and confirm malunion. Clinical history of prior fracture and healing process is also considered.

Treatment Options

• Pain management with medications or physical therapy to improve function.
• Rehabilitation exercises to restore shoulder mobility and strength.
• Surgical intervention may be considered for severe malunion affecting function.
• Orthopedic evaluation to determine the need for corrective procedures.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and response to treatment. Most patients experience improved function with rehabilitation, though some may have persistent limitations. Regular follow-up with an orthopedic specialist is recommended to monitor healing and adjust treatment as needed.

Complications

• Chronic pain or reduced shoulder mobility.
• Impaired muscle function due to abnormal bone alignment.
• Increased risk of future shoulder injuries.
• Potential need for additional surgery if malunion causes significant disability.

Lifestyle & Prevention

• Avoid high-impact activities that strain the shoulder until cleared by a healthcare provider.
• Engage in strength and flexibility exercises to support shoulder health.
• Maintain bone health through proper nutrition and, if applicable, osteoporosis management.
• Use protective gear during sports or activities with a risk of shoulder injury.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or inability to move the shoulder. Consult a healthcare provider if symptoms worsen or do not improve with treatment, or if you notice new deformity or functional decline.

Tips for Medical Coders

Document the subsequent encounter for fracture with malunion, including clinical notes confirming malunion and the healing status. Ensure the code S42.252P is used only when the fracture has healed with abnormal alignment and this is a follow-up visit for the condition. Include details on the fracture’s impact on function and any treatment provided during the encounter.
