S72.354Q Nondisplaced comminuted fracture of shaft of right femur, subsequent encounter for open fracture type I or II with malunion

Name of the Condition

• Nondisplaced comminuted fracture of shaft of right femur, subsequent encounter for open fracture type I or II with malunion (ICD-10 Code: S72.354Q)

Summary

This condition involves a fracture of the right femur (thighbone) where the bone is broken into multiple pieces, but the fragments remain in their normal anatomical position (nondisplaced). The fracture is localized to the shaft (central portion) of the bone and is classified as an open fracture type I or II, indicating a break in the skin with minimal contamination. This is a subsequent encounter for the injury, and malunion (improper healing) is present.

Causes

Such fractures typically result from high-impact trauma, such as motor vehicle accidents, falls from significant heights, or direct force to the thigh. Rotational or axial loading injuries can also cause this type of break. Open fractures occur when the broken bone pierces the skin, often due to the force of the injury. Malunion may develop if the fracture does not heal in proper alignment.

Risk Factors

• Osteoporosis or other bone-weakening conditions.
• Advanced age, due to decreased bone density.
• Participation in high-impact sports or activities.
• Prior history of fractures or bone abnormalities.
• Trauma involving significant force.
• Inadequate initial treatment or immobilization.

Symptoms

• Persistent pain at the fracture site, even after initial healing.
• Swelling, bruising, or tenderness around the affected area.
• Visible deformity or shortening of the leg due to malunion.
• Limited range of motion in the hip or knee.
• Possible difficulty bearing weight on the affected leg.
• Numbness or tingling if nerve involvement occurs.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays or CT scans are used to confirm the fracture type, assess healing, and identify malunion. The history of the injury and previous treatment is reviewed to determine the encounter type (subsequent) and fracture classification (open type I or II).

Treatment Options

Treatment focuses on managing malunion and restoring function. Options may include physical therapy to improve mobility and strength, orthopedic devices (e.g., braces or casts) for support, or surgical intervention (e.g., osteotomy or hardware revision) to realign the bone. Open fracture care may involve wound management to prevent infection.

Prognosis and Follow-Up

Prognosis depends on the severity of malunion and the patient’s overall health. Follow-up care is essential to monitor healing, assess functional recovery, and adjust treatment as needed. Long-term outcomes may include residual pain, limited mobility, or the need for additional interventions if malunion causes significant impairment.

Complications

• Chronic pain or discomfort.
• Reduced mobility or functional limitations.
• Increased risk of future fractures due to weakened bone.
• Nerve or vascular damage from malunion.
• Infection (if the open fracture was not properly managed).
• Need for additional surgery to correct malunion.

Lifestyle & Prevention

• Engage in weight-bearing exercises to strengthen bones (if cleared by a provider).
• Use protective gear during high-risk activities (e.g., sports).
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Avoid smoking, which can impair bone healing.
• Follow post-treatment guidelines to optimize recovery and reduce malunion risk.

When to Seek Professional Help

Seek care if you experience worsening pain, swelling, or deformity; difficulty bearing weight; signs of infection (e.g., fever, redness, drainage); or new numbness/tingling. Prompt evaluation is important to address complications or adjust treatment.

Tips for Medical Coders

Document the encounter as subsequent (not initial) and confirm the open fracture type (I or II) with malunion. Ensure clinical notes specify the fracture’s location (right femur shaft), displacement status (nondisplaced), and the presence of malunion to support accurate coding.
