S42.255G Nondisplaced fracture of greater tuberosity of left humerus, subsequent encounter for fracture with delayed healing

Name of the Condition

• Nondisplaced fracture of greater tuberosity of left humerus, subsequent encounter for fracture with delayed healing (ICD-10 Code: S42.255G)

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 classified as a subsequent encounter, indicating follow-up care after the initial injury, and is associated with delayed healing. The greater tuberosity serves as an attachment point for shoulder muscles and ligaments, and its fracture may affect shoulder function.

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. Delayed healing may occur due to factors like poor blood supply, inadequate immobilization, or underlying health conditions.

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.
• Smoking or poor nutrition, which can impair bone healing.

Symptoms

• Persistent pain in the shoulder or upper arm beyond the expected healing time.
• Swelling, bruising, and tenderness around the shoulder.
• Difficulty moving the arm, especially with overhead motions.
• Possible deformity or visible lump at the fracture site.
• Reduced strength or function in the affected shoulder.

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 healing progress. CT scans or MRIs may be ordered for detailed assessment of bone union or complications. Clinical evaluation of healing timelines and patient history is also critical.

Treatment Options

• Immobilization with a sling or brace to support the shoulder during healing.
• Pain management with medications or physical therapy.
• Surgical intervention if delayed healing persists or displacement occurs.
• Rehabilitation exercises to restore strength and mobility once healing is confirmed.
• Monitoring for signs of nonunion or malunion.

Prognosis and Follow-Up

Most nondisplaced fractures heal with proper care, but delayed healing may extend recovery time. Follow-up appointments are necessary to assess progress and adjust treatment. Full recovery depends on adherence to immobilization, rehabilitation, and addressing underlying risk factors. Long-term function is generally good with appropriate management.

Complications

• Nonunion (failure of the bone to heal).
• Malunion (healing in an incorrect position).
• Chronic pain or reduced shoulder function.
• Muscle weakness or atrophy from prolonged immobilization.
• Infection (rare, but possible with surgical intervention).

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Engage in low-impact exercises to preserve joint mobility.
• Use protective gear during sports or activities with fall risks.
• Quit smoking and limit alcohol to improve healing outcomes.

When to Seek Professional Help

• Persistent or worsening pain despite treatment.
• New swelling, bruising, or deformity at the injury site.
• Inability to move the arm or shoulder.
• Signs of infection, such as fever or redness.
• Delayed healing concerns based on follow-up imaging.

Tips for Medical Coders

This code (S42.255G) is used for a subsequent encounter for a nondisplaced fracture of the greater tuberosity of the left humerus with delayed healing. Documentation should specify the fracture type, laterality (left), encounter type (subsequent), and healing status (delayed). Ensure clinical notes support the delayed healing diagnosis and align with the code’s description.
