S72.115M Nondisplaced fracture of greater trochanter of left femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Nondisplaced fracture of greater trochanter of left femur, subsequent encounter for open fracture type I or II 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 applies to a subsequent encounter for an open fracture type I or II (with minimal to moderate skin wound contamination) that has failed to heal (nonunion). The condition requires ongoing medical management due to the persistent fracture and associated open wound.

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 but involve an external wound, often from the trauma itself or subsequent injury. Nonunion may develop due to inadequate immobilization, poor blood supply, infection, or other factors affecting 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.
• High-impact activities or occupations.
• Poor nutrition or smoking, which can impair bone healing.

Symptoms

• Persistent hip or groin pain, often worsened by movement.
• Inability to bear weight on the affected leg.
• Swelling, bruising, or deformity around the hip.
• Leg shortening or external rotation.
• Visible or palpable wound (for open fractures) with possible drainage or signs of infection.
• Delayed healing or persistent pain despite treatment.

Diagnosis

Physical examination to assess pain, range of motion, deformity, and wound status. Imaging studies, including X-rays or CT scans, to confirm the fracture and assess for nonunion (e.g., persistent fracture line, lack of callus formation). Laboratory tests may be ordered to evaluate for infection or nutritional deficiencies affecting healing. Documentation of the open fracture type (I or II) and evidence of nonunion is critical for coding.

Treatment Options

• Immobilization with a brace or cast to stabilize the fracture.
• Surgical intervention, such as internal fixation or bone grafting, to promote healing.
• Wound care for open fractures, including cleaning, dressing changes, and possible antibiotics.
• Pain management with medications or physical therapy.
• Nutritional support or smoking cessation to optimize healing.
• Monitoring for infection or other complications.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient health, and treatment adherence. Nonunion may require additional interventions, such as surgery, to achieve healing. Follow-up appointments are necessary to monitor healing progress, assess for complications, and adjust treatment. Long-term management may involve physical therapy to restore function and prevent future fractures.

Complications

• Infection at the fracture site or wound.
• Chronic pain or disability.
• Nonunion or malunion (improper healing).
• Avascular necrosis (loss of blood supply to the bone).
• Deep vein thrombosis (blood clots) or pulmonary embolism.
• Nerve or vascular damage.

Lifestyle & Prevention

• Maintain bone health with calcium and vitamin D intake.
• Engage in weight-bearing exercise 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 medication and lifestyle changes.
• Quit smoking and limit alcohol to support healing.

When to Seek Professional Help

Seek immediate medical attention for severe pain, inability to bear weight, visible wound, or signs of infection (e.g., redness, swelling, fever). Contact a healthcare provider if pain persists, worsens, or if there are new symptoms like numbness, tingling, or swelling in the leg.

Tips for Medical Coders

Document the fracture type (nondisplaced), laterality (left femur), encounter type (subsequent), open fracture classification (type I or II), and nonunion status clearly. Ensure the medical record supports the open fracture details (e.g., wound size, contamination) and evidence of nonunion (e.g., imaging findings, clinical assessment). Code S72.115M is specific to the left femur; do not use for right-sided or unspecified fractures.
