S42.264D Nondisplaced fracture of lesser tuberosity of right humerus, subsequent encounter for fracture with routine healing

Name of the Condition

• Nondisplaced fracture of lesser tuberosity of right humerus, subsequent encounter for fracture with routine healing (ICD Code: S42.264D)

Summary

This condition describes a nondisplaced fracture of the lesser tuberosity on the right humerus, occurring during a subsequent encounter for fracture care with evidence of routine healing. The lesser tuberosity is a bony prominence on the front of the humerus near the shoulder joint, serving as an attachment point for the subscapularis muscle. The fracture involves no significant separation of bone fragments, and healing is progressing as expected without complications.

Causes

Nondisplaced fractures of the lesser tuberosity typically result from direct trauma, such as falls onto the shoulder, motor vehicle accidents, or high-impact sports injuries. Low-energy trauma may also cause this type of fracture in individuals with weakened bones. The subsequent encounter phase indicates the fracture is in the healing stage, often following initial treatment.

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

• Mild to moderate pain in the shoulder or upper arm, decreasing over time.
• Minimal swelling or bruising as healing progresses.
• Gradual improvement in range of motion and arm function.
• No visible deformity, as the fracture remains nondisplaced.

Diagnosis

Physical examination to assess pain, range of motion, and healing progress. Imaging tests, including X-rays, to confirm routine healing and absence of displacement. Clinical evaluation to ensure no new symptoms or complications have emerged since the initial fracture.

Treatment Options

• Continued immobilization or protective measures as needed.
• Pain management with over-the-counter or prescribed medications.
• Physical therapy to restore strength and mobility.
• Monitoring for signs of delayed healing or complications.

Prognosis and Follow-Up

Most nondisplaced fractures of the lesser tuberosity heal well with routine care, allowing for full functional recovery. Follow-up appointments are typically scheduled to assess healing progress and adjust treatment plans. Return to normal activities is gradual, guided by pain levels and functional improvement.

Complications

• Delayed healing or nonunion, though rare with nondisplaced fractures.
• Residual stiffness or limited range of motion.
• Infection or other complications from the initial injury, if present.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Engage in gentle range-of-motion exercises as recommended.
• Maintain bone health through a balanced diet and regular exercise.
• Use protective gear during sports or activities with fall risks.

When to Seek Professional Help

• Increasing pain, swelling, or bruising.
• New numbness, tingling, or weakness in the arm or hand.
• Inability to move the arm or bear weight.
• Signs of infection, such as redness, warmth, or fever.

Tips for Medical Coders

Document the subsequent encounter for fracture with routine healing, including clinical notes confirming healing progress and absence of complications. Ensure the right humerus and lesser tuberosity are clearly specified, and the nondisplaced nature of the fracture is documented. Use this code only for encounters where healing is proceeding as expected.
