S42.255A Nondisplaced fracture of greater tuberosity of left humerus, initial encounter for closed fracture

Name of the Condition

• Nondisplaced fracture of greater tuberosity of left humerus, initial encounter for closed fracture (ICD-10 Code: S42.255A)

Summary

This condition involves a nondisplaced 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 is characterized by a break in the bone without significant separation of fragments, and it is classified as closed (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

Treatment may include immobilization with a sling or brace to support healing, pain management, and physical therapy to restore range of motion and strength. Surgical intervention is typically not required for nondisplaced fractures unless other complications arise.

Prognosis and Follow-Up

Most nondisplaced fractures heal well with conservative management. Follow-up care involves monitoring for proper healing and gradual return to activity. Physical therapy may be recommended to restore full function.

Complications

Potential complications include nonunion (failure to heal), malunion (improper healing), or persistent pain. Rarely, nerve or blood vessel injury may occur.

Lifestyle & Prevention

• Use protective gear during high-risk activities.
• Maintain bone health through diet and exercise.
• Avoid falls by modifying home environments (e.g., removing tripping hazards).

When to Seek Professional Help

Seek immediate care for severe pain, inability to move the arm, visible deformity, or signs of infection (e.g., fever, increased swelling).

Tips for Medical Coders

Document the fracture as nondisplaced, left-sided, and closed. Specify "initial encounter" to indicate the first episode of care. Ensure clinical notes confirm no displacement and that the fracture is closed (no open wound) to support accurate coding.
