S72.035K Nondisplaced midcervical fracture of left femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Nondisplaced midcervical fracture of left femur, subsequent encounter for closed fracture with nonunion

Summary

A nondisplaced midcervical fracture of the left femur is a break in the middle portion of the femoral neck (the region connecting the femoral head to the shaft) on the left side, with the bone fragments remaining in their normal alignment. This code indicates a subsequent encounter for a closed fracture that has failed to heal (nonunion). Nonunion occurs when the bone does not properly fuse after an initial injury, requiring ongoing management to address the fracture and promote healing.

Causes

High-impact trauma, such as falls or motor vehicle accidents. Low-impact trauma in individuals with weakened bones (e.g., osteoporosis). Nonunion may result from inadequate initial treatment, poor blood supply to the fracture site, or excessive movement during healing.

Risk Factors

• Advanced age, particularly in those over 65
• Osteoporosis or other bone density disorders
• Female gender, due to higher osteoporosis prevalence
• History of prior fractures or bone diseases
• Participation in high-risk activities (e.g., contact sports)
• Factors that impair healing, such as smoking, diabetes, or certain medications

Symptoms

• Persistent hip or groin pain, often worsening with activity
• Inability to bear weight on the affected leg
• Swelling, bruising, or tenderness around the hip
• Leg shortening or external rotation of the affected limb
• Limited range of motion in the hip joint
• Possible clicking or grinding sensations during movement

Diagnosis

Physical examination to assess pain, mobility, and limb alignment. Imaging studies, including X-rays or CT scans, to evaluate the fracture site and confirm nonunion. Additional tests, such as bone scans or MRI, may be used to assess blood flow and healing potential.

Treatment Options

• Immobilization with a brace or cast to stabilize the fracture
• Surgical intervention, such as internal fixation with screws or plates, to promote healing
• Bone grafting to stimulate bone growth at the fracture site
• Physical therapy to restore strength and mobility
• Pain management with medications or other modalities

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion, overall health, and response to treatment. Regular follow-up with imaging is necessary to monitor healing progress. Full recovery may take several months, and some patients may experience long-term limitations in mobility or function.

Complications

• Chronic pain or disability
• Avascular necrosis (loss of blood supply to the femoral head)
• Infection (if surgical intervention is required)
• Malunion (improper healing of the fracture)
• Reduced quality of life due to mobility limitations

Lifestyle & Prevention

• Maintain a healthy diet rich in calcium and vitamin D to support bone health
• Engage in weight-bearing exercises to strengthen bones
• Avoid high-risk activities that increase fracture risk
• Use assistive devices, such as canes or walkers, to prevent falls
• Quit smoking and limit alcohol consumption, as these can impair bone healing

When to Seek Professional Help

Seek immediate medical attention if you experience sudden, severe hip pain, inability to bear weight, or signs of infection (e.g., fever, redness, or drainage). Contact your healthcare provider if pain persists or worsens despite treatment, or if you notice new symptoms such as swelling or deformity.

Tips for Medical Coders

This code is used for a subsequent encounter for a closed fracture with nonunion. Document the fracture's location (midcervical, left femur), the encounter type (subsequent), and the presence of nonunion. Ensure documentation supports the closed nature of the fracture and the failure of the bone to heal. Include details about treatment provided and any imaging results confirming nonunion.
