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

Name of the Condition

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

Summary

This condition involves a displaced fracture of the lesser tuberosity, a bony prominence on the humerus near the shoulder joint, with evidence of routine healing during a subsequent encounter. The fracture is characterized by separated bone fragments, which may affect the attachment of the subscapularis tendon and surrounding structures. Routine healing indicates the fracture is progressing as expected without complications.

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. The subsequent encounter phase reflects ongoing management after the initial injury.

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.

Symptoms

• Intense pain in the shoulder or upper arm.
• Swelling, bruising, and visible deformity at the fracture site.
• Inability to move the arm or bear weight.
• Numbness or tingling in the hand or fingers if nerve involvement occurs.

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. Documentation must confirm routine healing and a subsequent encounter for fracture care.

Treatment Options

• Immobilization with a sling or brace to support healing.
• Pain management through medications or physical therapy.
• Surgical intervention if displacement is severe or fails to heal properly.
• Rehabilitation exercises to restore strength and mobility.

Prognosis and Follow-Up

Most fractures with routine healing heal within 6–12 weeks with proper care. Follow-up appointments monitor progress and adjust treatment as needed. Full recovery depends on fracture severity and adherence to rehabilitation.

Complications

• Nonunion or delayed healing if treatment is inadequate.
• Arthritis or joint stiffness from prolonged immobility.
• Nerve or blood vessel damage in severe cases.
• Chronic pain or reduced function without proper rehabilitation.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by modifying home environments for safety.
• Follow post-injury guidelines to support healing.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility does not improve. Contact a provider immediately for signs of infection, numbness, or circulation issues.

Tips for Medical Coders

Document the fracture type (displaced), anatomical site (lesser tuberosity of unspecified humerus), and encounter type (subsequent with routine healing). Ensure clinical notes confirm healing status to support the code. Verify no complications are present that would require a different code.
