S72.146P Nondisplaced intertrochanteric fracture of unspecified femur, subsequent encounter for closed fracture with malunion

Name of the Condition

Nondisplaced intertrochanteric fracture of unspecified femur, subsequent encounter for closed fracture with malunion

Summary

A nondisplaced intertrochanteric fracture of the femur is a break in the upper thigh bone between the greater and lesser trochanters where the bone fragments remain aligned. This subsequent encounter code applies to a closed fracture (no open wound) that has healed with malunion, meaning the bone fragments have united in a non-anatomical position. The term "unspecified femur" indicates the side (left or right) is not documented. This condition requires evaluation to assess the malunion and guide ongoing management.

Causes

Intertrochanteric fractures typically result from trauma, such as falls or direct impact to the hip. Malunion occurs when the fracture heals in a misaligned position, often due to inadequate immobilization, poor blood supply, or insufficient stabilization during initial treatment. Weakened bone structure, commonly from osteoporosis, may increase susceptibility to fracture and malunion.

Risk Factors

• Advanced age, particularly in individuals over 65
• Osteoporosis or other bone-weakening conditions
• History of previous fractures
• Sedentary lifestyle or reduced bone density
• Inadequate initial fracture management or immobilization

Symptoms

• Persistent hip or groin pain
• Difficulty bearing weight on the affected leg
• Altered gait or limping
• Possible leg length discrepancy
• Swelling or bruising around the hip (if recent)

Diagnosis

Diagnosis involves a physical examination to assess pain, mobility, and deformity. Imaging tests, such as X-rays, are used to confirm the malunion and evaluate bone alignment. Additional imaging like CT scans may be used for detailed assessment of the fracture site and healing.

Treatment Options

• Orthopedic evaluation to determine if realignment or stabilization is needed
• Physical therapy to improve mobility and strength
• Pain management with medications or other modalities
• Possible surgical intervention if malunion causes functional impairment or pain
• Assistive devices (e.g., crutches, walkers) to support weight-bearing

Prognosis and Follow-Up

Prognosis depends on the severity of the malunion and the patient’s overall health. Most patients recover with conservative management, but malunion may lead to long-term mobility issues. Regular follow-up with imaging and clinical assessments is recommended to monitor healing and functional status.

Complications

• Chronic pain or discomfort
• Reduced mobility or gait abnormalities
• Increased risk of future fractures
• Potential need for surgical correction if malunion worsens
• Joint degeneration or arthritis over time

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)
• Maintain a healthy weight to reduce stress on bones
• Avoid high-impact activities that increase fracture risk

When to Seek Professional Help

Seek medical attention if you experience:

• Sudden or worsening hip pain
• Inability to bear weight on the affected leg
• New swelling, bruising, or deformity
• Signs of infection (e.g., fever, redness, drainage)
• Persistent difficulty with mobility or daily activities

Tips for Medical Coders

This code (S72.146P) is used for a subsequent encounter of a closed, nondisplaced intertrochanteric fracture with malunion. Documentation should specify the fracture’s status (malunion), that it is closed, and that this is a follow-up visit. Ensure the encounter is subsequent (not initial) and that the fracture site (unspecified femur) is clearly documented. Avoid using this code for open fractures or initial encounters.
