S72.115K Nondisplaced fracture of greater trochanter of left femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Nondisplaced fracture of greater trochanter of left femur, subsequent encounter for closed fracture with nonunion

Summary

A nondisplaced fracture of the greater trochanter of the left femur is a break in the bony prominence on the upper part of the left thigh bone (femur) near the hip joint, where the bone fragment remains in its normal position. This code represents a subsequent encounter for a closed fracture that has failed to heal (nonunion) after an initial injury. The fracture is classified as closed, meaning no open wound is present, and the nonunion indicates incomplete healing despite prior treatment.

Causes

Nondisplaced fractures of the greater trochanter commonly result from direct trauma, such as falls or high-impact injuries. They can also occur in individuals with weakened bones due to conditions like osteoporosis, where even minor stress may cause a fracture without displacement. Nonunion may develop due to inadequate immobilization, poor blood supply to the bone, infection, or underlying health conditions that impair healing.

Risk Factors

• Advanced age, particularly in postmenopausal women with osteoporosis.
• Conditions that weaken bones, such as osteoporosis, cancer, or metabolic disorders.
• History of previous fractures or falls.
• Sedentary lifestyle or limited mobility.
• Smoking or poor nutrition, which can impair bone healing.

Symptoms

• Persistent hip or groin pain, often unchanged or worsening over time.
• Inability to bear weight on the affected leg.
• Swelling, bruising, or deformity around the hip.
• Leg shortening or external rotation.
• Lack of improvement in symptoms despite prior treatment.

Diagnosis

Physical examination to assess pain, range of motion, and deformity. Imaging studies, including X-rays or CT scans, to confirm the fracture and evaluate for nonunion (e.g., visible gap between bone fragments or absence of healing signs). Additional tests, such as bone scans or MRI, may be used to assess blood flow or detect infection.

Treatment Options

• Immobilization with a brace or cast to stabilize the fracture.
• Pain management with medications or physical therapy.
• Surgical intervention, such as internal fixation or bone grafting, to promote healing.
• Addressing underlying conditions (e.g., osteoporosis) to support bone repair.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and response to treatment. Follow-up imaging is typically required to monitor healing progress. Long-term management may involve ongoing physical therapy to restore function and prevent complications like arthritis or chronic pain.

Complications

• Chronic pain or disability.
• Nonunion or delayed union.
• Arthritis in the hip joint.
• Infection (if surgery is performed).
• Reduced mobility or quality of life.

Lifestyle & Prevention

• Maintain bone health with calcium and vitamin D intake.
• Engage in weight-bearing exercises to strengthen bones.
• Use fall prevention strategies, such as home modifications or assistive devices.
• Avoid high-impact activities that increase fracture risk.

When to Seek Professional Help

Seek immediate medical attention if you experience severe hip pain, inability to bear weight, or signs of infection (e.g., fever, redness, or drainage). Follow up with a healthcare provider if symptoms persist or worsen despite treatment.

Tips for Medical Coders

Document the subsequent encounter for a closed fracture with nonunion, including details of prior treatment and evidence of nonunion (e.g., imaging reports). Ensure the code S72.115K is used only when the fracture is closed and nonunion is confirmed. Include clinical notes supporting the nonunion diagnosis to justify the code assignment.
