S72.002M Fracture of unspecified part of neck of left femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Fracture of unspecified part of neck of left femur, subsequent encounter for open fracture type I or II with nonunion

Summary

A fracture of the unspecified part of the neck of the left femur involves a break in the upper portion of the thigh bone near the hip joint. This subsequent encounter code applies to cases where the fracture is open (type I or II) and has failed to heal (nonunion) after prior treatment. The condition requires ongoing evaluation to address both the fracture and the nonunion, with management focused on promoting healing and restoring function.

Causes

Traumatic events such as falls or direct impact injuries. Underlying bone conditions that weaken structural integrity, such as osteoporosis. Inadequate initial treatment or poor healing response contributing to nonunion.

Risk Factors

• Advanced age, particularly in individuals with reduced bone density
• Osteoporosis or other metabolic bone diseases
• Open fracture type I or II, which may increase infection or healing risks
• Prior history of hip or femoral fractures
• Factors impairing healing (e.g., smoking, diabetes, poor nutrition)

Symptoms

• Persistent or recurrent hip/groin pain
• Inability to bear weight on the affected leg
• Swelling or bruising around the hip
• The affected leg may appear shorter or turned outward
• Visible wound or laceration at the fracture site (due to open fracture)
• Possible signs of nonunion, such as lack of progress in healing over time

Diagnosis

Physical examination to assess pain, mobility, and leg alignment, followed by imaging studies such as X-rays or CT scans to confirm the fracture and evaluate for nonunion. Assessment of the open wound (type I or II) and any signs of infection or delayed healing.

Treatment Options

• Surgical intervention (e.g., internal fixation, bone grafting) to address nonunion and stabilize the fracture
• Wound care for the open fracture (type I or II) to prevent infection
• Physical therapy to restore mobility and strength post-treatment
• Pain management and immobilization as needed
• Monitoring for complications related to the open fracture or nonunion

Prognosis and Follow-Up

Recovery depends on the severity of the nonunion, the success of surgical intervention, and adherence to rehabilitation. Regular follow-up with imaging is typically required to assess healing progress. Long-term outcomes may include restored function or potential for chronic pain or mobility limitations if healing is incomplete.

Complications

• Infection at the fracture site (due to open fracture)
• Delayed or failed healing (nonunion)
• Avascular necrosis of the femoral head
• Chronic pain or arthritis in the hip joint
• Leg length discrepancy or deformity
• Reduced mobility or functional impairment

Lifestyle & Prevention

• Maintain bone health through adequate calcium and vitamin D intake
• Engage in weight-bearing exercises to strengthen bones
• Avoid high-risk activities that increase fall or trauma risk
• Manage underlying conditions (e.g., osteoporosis) with medical guidance
• Follow post-treatment care instructions to support healing

When to Seek Professional Help

Seek immediate medical attention for severe pain, inability to bear weight, visible wound at the hip, or signs of infection (e.g., redness, pus, fever). Ongoing evaluation is necessary if pain persists or worsens, or if there are concerns about healing progress.

Tips for Medical Coders

Document the fracture type (open, type I or II), the presence of nonunion, and the subsequent encounter status clearly. Include details on prior treatments, imaging results, and clinical findings to support the diagnosis. Ensure the open fracture classification and nonunion are explicitly noted to justify the code assignment.
