S72.356M Nondisplaced comminuted fracture of shaft of unspecified femur, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Nondisplaced comminuted fracture of shaft of unspecified femur, subsequent encounter for open fracture type I or II with nonunion (ICD-10 Code: S72.356M)

Summary

This condition involves a fracture of the femur (thighbone) where the bone is broken into multiple pieces but remains in its original position. It is a subsequent encounter for an open fracture type I or II, meaning the skin was broken during the initial injury, and the fracture has not healed (nonunion) during follow-up care.

Causes

Such fractures typically result from high-impact trauma, such as motor vehicle accidents, falls from significant heights, or direct force to the thigh. Open fractures may occur when the broken bone pierces the skin or when trauma causes an external wound, and nonunion can develop due to inadequate stabilization, infection, or poor blood supply.

Risk Factors

• Osteoporosis or other bone-weakening conditions.
• Advanced age, due to decreased bone density.
• Prior history of fractures or bone abnormalities.
• Trauma involving significant force that disrupts the skin.
• Inadequate initial treatment or complications during healing.

Symptoms

• Severe pain in the thigh at the fracture site.
• Swelling, bruising, or tenderness around the area.
• Inability to bear weight on the affected leg.
• Visible wound or break in the skin (open fracture).
• Possible numbness or tingling if nerve involvement occurs.
• Persistent pain or instability indicating nonunion.

Diagnosis

Physical examination to assess pain, alignment, and wound status. Imaging tests such as X-rays to visualize the fracture and assess for nonunion. Additional scans (e.g., CT) may be used for detailed assessment if needed. Evaluation of the open fracture type and healing progress is critical.

Treatment Options

Treatment often involves surgical intervention to stabilize the bone fragments with metal rods, screws, or plates, especially if nonunion is present. Wound care for the open fracture, pain management, and physical therapy are essential. Bone grafting or other procedures may be required to promote healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the success of stabilization, and the body's healing response. Regular follow-up with imaging is necessary to monitor for union. Recovery may be prolonged due to nonunion, requiring ongoing medical management.

Complications

• Infection at the fracture site or wound.
• Delayed or failed healing (nonunion).
• Nerve or vascular damage.
• Chronic pain or instability.
• Malalignment of the bone.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow prescribed weight-bearing restrictions.
• Maintain bone health through diet and exercise (as advised).
• Use protective gear during activities to reduce trauma risk.

When to Seek Professional Help

Seek immediate care for severe pain, swelling, or signs of infection (e.g., redness, pus). Contact a provider if pain worsens, mobility decreases, or the wound shows no improvement.

Tips for Medical Coders

Document the encounter as subsequent for an open fracture type I or II with nonunion. Ensure the fracture is classified as nondisplaced and comminuted, localized to the femur shaft, and specify the nonunion status. Include details on wound care and any surgical interventions performed.
