S72.116M Nondisplaced fracture of greater trochanter of unspecified femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Nondisplaced fracture of greater trochanter of unspecified femur, subsequent encounter for open fracture type I or II 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 specifies a subsequent encounter for an open fracture type I or II (indicating a break in the skin with minimal to moderate contamination) that has failed to heal (nonunion). The fracture typically results from trauma or weakened bone structure and is documented during follow-up care after initial 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. Open fractures may result from the same mechanisms, with the added factor of the fracture penetrating the skin. Nonunion may develop due to inadequate immobilization, poor blood supply, infection, or persistent instability at the fracture site.

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.
• High-impact activities or trauma exposure.
• Poor nutritional status or smoking, which can impair bone healing.

Symptoms

• Persistent hip or groin pain, often worsened by movement or weight-bearing.
• Inability to bear weight on the affected leg.
• Swelling, bruising, or deformity around the hip.
• Leg shortening or external rotation.
• Possible signs of infection (e.g., redness, warmth, or drainage) if the fracture is open.

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., persistent gap or lack of bone healing). Assessment of the open wound (if present) to determine contamination level and risk of infection. Laboratory tests may be ordered to check for infection or nutritional deficiencies affecting healing.

Treatment Options

• Immobilization with a brace or cast to stabilize the fracture.
• Surgical intervention, such as internal fixation or bone grafting, to promote healing in cases of nonunion.
• Antibiotics for open fractures to prevent or treat infection.
• Pain management with medications or physical therapy.
• Nutritional support (e.g., calcium, vitamin D) to aid bone healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the presence of infection, and the effectiveness of treatment. Nonunion may require additional interventions, and healing time is often prolonged. Regular follow-up with imaging studies is necessary to monitor progress. Physical therapy may be recommended to restore mobility and strength once healing is underway.

Complications

• Nonunion or delayed healing.
• Infection, particularly with open fractures.
• Chronic pain or arthritis in the hip joint.
• Leg length discrepancy or deformity.
• Reduced mobility or functional impairment.

Lifestyle & Prevention

• Maintain bone health with a balanced diet rich in calcium and vitamin D.
• Engage in weight-bearing exercises to strengthen bones.
• Use fall prevention strategies, such as removing tripping hazards and wearing supportive footwear.
• Avoid high-impact activities that increase fracture risk.
• Quit smoking, as it impairs bone healing.

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, drainage, or increased redness). Follow up with your healthcare provider if pain persists or worsens, or if you notice new swelling or deformity.

Tips for Medical Coders

Document the encounter as a subsequent visit (not initial) and specify the open fracture type (I or II) and nonunion. Ensure clinical notes confirm the fracture type, healing status, and any complications (e.g., infection) to support coding accuracy. Code S72.116M is appropriate for this scenario.
