S72.045P Nondisplaced fracture of base of neck of left femur, subsequent encounter for closed fracture with malunion

Name of the Condition

• Nondisplaced fracture of base of neck of left femur, subsequent encounter for closed fracture with malunion (S72.045P)

Summary

This condition involves a break in the upper portion of the left femur (thigh bone) at the base of the femoral neck, near the hip joint. The term "nondisplaced" indicates that the bone fragments remain in their normal anatomical position. The "subsequent encounter" modifier denotes follow-up care after the initial treatment phase, and "malunion" refers to healing in a non-anatomical position, which may affect joint function. This type of fracture requires ongoing evaluation to assess healing and manage any functional impairments.

Causes

High-impact trauma, such as falls or motor vehicle accidents. Low-impact trauma in individuals with weakened bones (e.g., osteoporosis). Repetitive stress or overuse injuries in rare cases.

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)

Symptoms

• Persistent hip or groin pain
• Difficulty bearing 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 functional impairment due to malunion

Diagnosis

Physical examination to assess pain, mobility, and limb alignment. Imaging studies, including X-rays or CT scans, to visualize the fracture and evaluate healing status. Assessment of malunion through comparison with prior imaging or anatomical landmarks.

Treatment Options

• Pain management with analgesics or anti-inflammatory medications
• Physical therapy to improve mobility and strength
• Orthopedic evaluation for potential corrective procedures if malunion causes significant impairment
• Assistive devices (e.g., crutches, walkers) to reduce weight-bearing stress
• Monitoring for complications related to malunion

Prognosis and Follow-Up

Prognosis depends on the degree of malunion and its impact on hip function. Most patients experience improved symptoms with conservative management, though some may require surgical intervention for severe cases. Regular follow-up appointments are necessary to monitor healing and adjust treatment plans as needed.

Complications

• Chronic pain or discomfort
• Reduced mobility or functional limitations
• Increased risk of future fractures due to altered bone structure
• Potential need for surgical correction if malunion is severe

Lifestyle & Prevention

• Engage in weight-bearing exercises to strengthen bones
• Ensure adequate calcium and vitamin D intake
• Use fall prevention strategies (e.g., home modifications, assistive devices)
• Avoid high-risk activities that may increase fracture risk
• Maintain a healthy weight to reduce stress on hip joints

When to Seek Professional Help

Seek immediate medical attention if experiencing severe pain, inability to bear weight, or signs of infection (e.g., fever, increased swelling). Follow up with a healthcare provider if symptoms worsen or new complications arise during recovery.

Tips for Medical Coders

Document the presence of malunion and the subsequent encounter status clearly in the medical record. Ensure that imaging or clinical notes confirm the fracture is closed and healing in a non-anatomical position. Use this code only when the encounter is for follow-up care of a previously treated fracture with malunion.
