S42.256A Nondisplaced fracture of greater tuberosity of unspecified humerus, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of greater tuberosity of unspecified humerus, initial encounter for closed fracture (ICD-10 Code: S42.256A)

Summary

This condition involves a nondisplaced fracture of the greater tuberosity, a bony prominence on the upper end of the humerus (upper arm bone) near the shoulder joint. The fracture is characterized by a break in the bone without significant separation of fragments, and it is classified as a closed fracture (no open wound) during the initial encounter.

Causes

Fractures of the greater tuberosity typically result from direct trauma, such as a fall onto the shoulder, a direct blow to the area, or forceful muscle contraction (e.g., during sports or lifting). Low-energy trauma may also cause the injury in individuals with weakened bones.

Risk Factors

• Participation in contact sports or activities with a high risk of falls.
• Osteoporosis or other conditions that weaken bone density.
• Advanced age, which increases susceptibility to fractures.
• Previous shoulder injuries or surgeries.

Symptoms

• Acute pain in the shoulder or upper arm.
• Swelling, bruising, and tenderness around the shoulder.
• Difficulty moving the arm, especially with overhead motions.
• Possible deformity or visible lump at the fracture site.

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays, are used to confirm the fracture and evaluate displacement. CT scans or MRIs may be ordered for detailed assessment if needed.

Treatment Options

• Immobilization with a sling or brace to support the shoulder and allow healing.
• Pain management with medications or ice therapy.
• Physical therapy to restore range of motion and strength once healing progresses.
• Surgical intervention is rarely required for nondisplaced fractures but may be considered if displacement occurs.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative treatment, and patients typically regain full shoulder function. Follow-up appointments monitor healing progress, and imaging may be repeated to confirm bone union. Return to normal activities is gradual, guided by pain and functional recovery.

Complications

• Delayed union or nonunion of the fracture.
• Shoulder stiffness or reduced range of motion.
• Chronic pain or instability in the shoulder.
• Rarely, nerve or blood vessel injury near the fracture site.

Lifestyle & Prevention

• Use protective gear during contact sports or high-risk activities.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid falls by modifying the home environment (e.g., removing tripping hazards).
• Engage in regular strength training to support bone and muscle integrity.

When to Seek Professional Help

Seek immediate medical attention if there is severe pain, inability to move the arm, visible deformity, or signs of infection (e.g., fever, redness, drainage). Follow up with a healthcare provider if pain worsens or does not improve with initial treatment.

Tips for Medical Coders

Document the encounter as "initial" for a closed fracture, specifying the nondisplaced nature of the greater tuberosity fracture. Ensure the humerus is documented as "unspecified" if the side is not clearly identified. Include details on trauma mechanism, imaging results, and treatment plan to support code accuracy.
