S72.354K Nondisplaced comminuted fracture of shaft of right femur, subsequent encounter for closed fracture with nonunion

Name of the Condition

• Nondisplaced comminuted fracture of shaft of right femur, subsequent encounter for closed fracture with nonunion (ICD-10 Code: S72.354K)

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. This is a subsequent encounter for a closed fracture (no break in the skin) with nonunion, meaning the bone has failed to heal properly after an expected period.

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. Nonunion may occur due to inadequate immobilization, poor blood supply, infection, or excessive movement at the fracture site.

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.
• Smoking or poor nutrition, which can impair healing.

Symptoms

• Persistent or recurrent pain at the fracture site.
• Swelling, bruising, or tenderness that does not resolve.
• Inability to bear weight on the affected leg.
• Possible visible deformity or shortening of the leg (in displaced fractures).
• Numbness or tingling if nerve involvement occurs.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays, CT scans, or MRI may be used to evaluate the fracture and check for nonunion. Bone scans or ultrasound may also help assess healing progress.

Treatment Options

Treatment may include surgical intervention, such as internal fixation with plates or screws, bone grafting, or external fixation. Non-surgical options like prolonged immobilization or electrical stimulation may be considered. Pain management and physical therapy are often part of the plan.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and response to treatment. Regular follow-up with imaging is necessary to monitor healing. Physical therapy may be required to restore strength and mobility. Full recovery can take several months to a year or more.

Complications

• Chronic pain or disability.
• Infection, especially if surgery is performed.
• Nerve or blood vessel damage.
• Malunion (healing in an abnormal position).
• Need for additional surgeries.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking, as it impairs healing.
• Use protective equipment during sports or activities with fall risks.
• Maintain a healthy weight to reduce stress on bones.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or inability to move the leg. Contact your healthcare provider if pain worsens, or if you notice signs of infection (e.g., fever, redness, drainage).

Tips for Medical Coders

Document the encounter as a subsequent visit for a closed fracture with nonunion. Ensure the record specifies the fracture is nondisplaced, comminuted, and involves the right femur shaft. Note the absence of open wound or infection, and confirm the nonunion status. Include details on treatment provided and any imaging results to support the code.
