S72.116K Nondisplaced fracture of greater trochanter of unspecified femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

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

Summary

A nondisplaced fracture of the greater trochanter of the femur is a break in the bony prominence on the upper part of the 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 fracture site, 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.
• Factors that impair healing, such as smoking, diabetes, or nutritional deficiencies.

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.
• Limited range of motion in the hip joint.

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. Additional tests, such as bone scans or MRI, may be used to assess blood flow and healing potential. Clinical history of prior treatment and lack of progress in healing is critical for diagnosis.

Treatment Options

Treatment focuses on promoting healing and restoring function. Options may include surgical intervention, such as internal fixation or bone grafting, to stabilize the fracture and encourage union. Non-surgical approaches, like prolonged immobilization or physical therapy, may be considered for select cases. Pain management and addressing underlying conditions (e.g., osteoporosis) are also important.

Prognosis and Follow-Up

Prognosis depends on the success of treatment and the patient’s overall health. Nonunion may require additional interventions, and recovery can be prolonged. Regular follow-up with imaging is necessary to monitor healing. Physical therapy is often recommended to restore strength and mobility once healing progresses.

Complications

• Persistent pain or functional impairment.
• Infection, particularly if surgical intervention is required.
• Avascular necrosis (loss of blood supply to the bone).
• Chronic disability or reduced quality of life.
• Need for additional surgeries if nonunion persists.

Lifestyle & Prevention

• Maintain bone health through adequate 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.
• Manage underlying conditions like osteoporosis with medical guidance.

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, drainage). Follow up with a healthcare provider if pain persists or worsens after initial treatment, as this may indicate nonunion or other complications.

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Ensure clinical notes specify the fracture type (nondisplaced), location (greater trochanter of unspecified femur), and the presence of nonunion. Include details about prior treatment and the reason for the current encounter to support coding accuracy.
