S72.143N Displaced intertrochanteric fracture of unspecified femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Name of the Condition

Displaced intertrochanteric fracture of unspecified femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Summary

A displaced intertrochanteric fracture is a break in the upper femur, occurring between the greater and lesser trochanters, where bone fragments are misaligned. This code applies to a subsequent encounter for an open fracture (types IIIA, IIIB, or IIIC) with nonunion, meaning the fracture has failed to heal properly after an initial injury. Open fractures involve communication with the external environment, and nonunion indicates a lack of bone healing progress.

Causes

These fractures typically result from high-impact trauma, such as falls or direct force to the hip. Open fractures may occur when the broken bone pierces the skin or when trauma causes an external wound. Nonunion can develop due to inadequate stabilization, poor blood supply, infection, or other factors interfering with healing.

Risk Factors

• Advanced age, particularly individuals over 65
• Osteoporosis or other bone-weakening conditions
• History of previous fractures or falls
• Sedentary lifestyle or reduced bone density
• High-impact trauma exposure (e.g., motor vehicle accidents)
• Inadequate initial fracture management

Symptoms

• Persistent severe pain in the hip or upper thigh
• Swelling and bruising around the hip
• Inability to bear weight or move the affected leg
• Shortening or abnormal rotation of the leg
• Possible signs of infection (e.g., redness, drainage) in open fractures

Diagnosis

Diagnosis involves a physical examination to assess pain, mobility, and deformity. Imaging tests, such as X-rays, are used to confirm the fracture and evaluate displacement. Additional imaging like CT scans or MRI may be ordered for detailed assessment if needed. Nonunion is diagnosed when imaging shows no progress in bone healing over time.

Treatment Options

• Surgical intervention to realign and stabilize the fracture, often using screws, plates, or rods
• Bone grafting to promote healing in cases of nonunion
• Antibiotics or wound care for open fractures to prevent infection
• Physical therapy to restore mobility and strength

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient health, and treatment success. Nonunion may require additional interventions, and open fractures carry a risk of infection. Regular follow-up with imaging is necessary to monitor healing progress. Recovery may take several months, with ongoing rehabilitation.

Complications

• Infection (especially with open fractures)
• Nonunion or malunion (improper healing)
• Avascular necrosis (loss of blood supply to the bone)
• Chronic pain or reduced mobility
• Deep vein thrombosis (blood clots)

Lifestyle & Prevention

• Maintain bone health through calcium and vitamin D intake
• Engage in weight-bearing exercise to strengthen bones
• Use assistive devices (e.g., canes, walkers) to prevent falls
• Address osteoporosis with medical management
• Ensure proper wound care for open fractures to reduce infection risk

When to Seek Professional Help

Seek immediate medical attention for severe hip pain, inability to bear weight, or signs of infection (e.g., fever, drainage). Follow up with a healthcare provider if pain persists or worsens after treatment, or if mobility does not improve as expected.

Tips for Medical Coders

This code is used for a subsequent encounter of a displaced intertrochanteric fracture with nonunion and open fracture types IIIA, IIIB, or IIIC. Document the fracture type (IIIA, IIIB, or IIIC) and confirm nonunion through imaging or clinical assessment. Ensure the encounter is classified as "subsequent" (not initial) and that the fracture is open with the specified severity.
