S72.351M Displaced comminuted fracture of shaft of right femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Displaced comminuted fracture of shaft of right femur, subsequent encounter for open fracture type I or II with nonunion (ICD-10 Code: S72.351M)

Summary

This condition involves a fracture of the right femur (thighbone) where the bone is broken into multiple pieces and the fragments are misaligned. The fracture is classified as open (type I or II), meaning the broken bone has pierced the skin, and it is a subsequent encounter for treatment. The term "nonunion" indicates the fracture has failed to heal properly after an expected period, requiring ongoing management.

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, often leading to both bone fragmentation and displacement. Nonunion may develop due to inadequate stabilization, poor blood supply, infection, or other factors interfering with healing.

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 fracture management or complications during healing.

Symptoms

• Persistent severe pain in the right thigh.
• Swelling, bruising, or tenderness at the fracture site.
• Inability to bear weight on the affected leg.
• Visible deformity or shortening of the leg (in displaced fractures).
• Open wound at the fracture site (indicating an open fracture).
• Possible numbness or tingling if nerve involvement occurs.
• Delayed or absent healing signs (e.g., persistent pain, lack of callus formation).

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays to visualize the fracture, assess displacement, and evaluate for nonunion (e.g., persistent fracture line, lack of bone healing). Additional scans (e.g., CT or MRI) may be used for detailed assessment of bone and soft tissue. Evaluation of the open wound and potential infection risk is also critical.

Treatment Options

Treatment focuses on promoting fracture healing and addressing nonunion. Options may include surgical intervention (e.g., internal fixation, bone grafting) to stabilize the fracture and encourage union. Antibiotics or wound care may be necessary for open fractures. Physical therapy is often recommended to restore function and strength once healing progresses. Monitoring for complications, such as infection or further displacement, is essential.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the success of treatment, and individual healing capacity. Nonunion may require extended treatment and follow-up. Regular imaging and clinical assessments are needed to monitor healing progress. Long-term follow-up may involve functional evaluations and adjustments to treatment plans as needed.

Complications

• Nonunion or delayed union of the fracture.
• Infection at the fracture site or open wound.
• Nerve or vascular damage.
• Chronic pain or disability.
• Malalignment or deformity of the femur.
• Post-traumatic arthritis.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow prescribed weight-bearing restrictions to support healing.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Use protective equipment during activities with fall or injury risk.
• Attend all follow-up appointments to monitor healing progress.

When to Seek Professional Help

Seek immediate medical attention if experiencing severe pain, swelling, or deformity in the thigh, especially if there is an open wound or inability to bear weight. Contact a healthcare provider if symptoms worsen, or if there are signs of infection (e.g., fever, increased redness, drainage from the wound). Follow up with a specialist if healing does not progress as expected.

Tips for Medical Coders

Document the encounter as a subsequent visit for an open fracture type I or II with nonunion. Ensure documentation specifies the fracture type (open), the encounter stage (subsequent), and the presence of nonunion. Include details on treatment provided, imaging results, and any complications to support accurate coding. Verify that all elements of the code (displaced, comminuted, shaft of right femur, open fracture type I or II, nonunion, subsequent encounter) are clearly documented.
