S42.263G Displaced fracture of lesser tuberosity of unspecified humerus, subsequent encounter for fracture with delayed healing

Name of the Condition

• Displaced fracture of lesser tuberosity of unspecified humerus, subsequent encounter for fracture with delayed healing (ICD Code: S42.263G)

Summary

This condition involves a displaced fracture of the lesser tuberosity, a bony prominence on the humerus near the shoulder joint. The fracture is characterized by the separation of bone fragments, which may affect the attachment of the subscapularis tendon and surrounding structures. The term "subsequent encounter for fracture with delayed healing" indicates this is a follow-up visit for a fracture that is not healing at the expected rate.

Causes

Displaced fractures of the lesser tuberosity typically result from direct trauma, such as a fall onto the shoulder or a forceful pull on the arm. High-impact injuries, including motor vehicle accidents or sports-related collisions, may also cause this type of fracture. Delayed healing can occur due to factors like poor blood supply, inadequate immobilization, or underlying health conditions.

Risk Factors

• Advanced age and osteoporosis, which reduce bone density.
• Participation in contact sports or activities with a high risk of falls.
• Previous fractures or bone disorders that weaken the skeletal structure.
• Smoking or poor nutrition, which impair bone healing.
• Certain medical conditions, such as diabetes or vascular disease.

Symptoms

• Persistent pain in the shoulder or upper arm, often worsening with movement.
• Swelling, bruising, and visible deformity at the fracture site.
• Limited range of motion or inability to bear weight on the arm.
• Numbness or tingling in the hand or fingers if nerve involvement occurs.
• Possible clicking or grinding sensations during arm movement.

Diagnosis

Physical examination to assess pain, range of motion, and deformity. Imaging tests, including X-rays, to visualize the fracture pattern and displacement. CT scans or MRIs may be used for detailed assessment of complex fractures or soft tissue damage. Follow-up imaging may be ordered to evaluate healing progress.

Treatment Options

• Immobilization with a sling or brace to stabilize the fracture.
• Pain management through medications or physical therapy.
• Surgical intervention, such as open reduction and internal fixation, if the fracture is severely displaced or fails to heal.
• Bone grafting or other procedures to promote healing in cases of delayed union.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, adherence to treatment, and overall health. Most fractures heal with proper care, but delayed healing may require extended follow-up. Regular imaging and clinical assessments are necessary to monitor progress. Physical therapy is often recommended to restore strength and mobility.

Complications

• Nonunion or malunion of the fracture.
• Chronic pain or stiffness in the shoulder.
• Nerve or blood vessel damage.
• Infection, particularly if surgery is performed.
• Post-traumatic arthritis in the shoulder joint.

Lifestyle & Prevention

• Maintain a diet rich in calcium and vitamin D to support bone health.
• Engage in regular weight-bearing exercise to strengthen bones.
• Use protective gear during high-risk activities.
• Avoid smoking and limit alcohol consumption, as these can impair healing.
• Follow safety guidelines to prevent falls, especially in older adults.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity after an injury. Contact a healthcare provider if symptoms worsen, or if you notice numbness, tingling, or difficulty moving the arm. Follow up as scheduled for delayed-healing fractures to ensure proper management.

Tips for Medical Coders

Document the encounter as a subsequent visit for a fracture with delayed healing. Ensure clinical notes specify the fracture type (displaced), anatomical site (lesser tuberosity of humerus), and the reason for delayed healing (e.g., poor blood supply, noncompliance with treatment). Code S42.263G is appropriate when the humerus side is unspecified and the fracture is not healing as expected.
