S72.355F Nondisplaced comminuted fracture of shaft of left femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Nondisplaced comminuted fracture of shaft of left femur, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing (ICD-10 Code: S72.355F)

Summary

This condition describes a fracture of the left femur (thighbone) where the bone is broken into multiple pieces (comminuted) but the fragments remain in their normal anatomical position (nondisplaced). The fracture is localized to the shaft (central portion) of the left femur. This is a subsequent encounter for an open fracture classified as type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and contamination, with routine healing progressing as expected.

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 trauma.

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.

Symptoms

• Severe, localized pain in the thigh.
• Swelling, bruising, or tenderness at the fracture site.
• Inability to bear weight on the affected leg.
• Possible visible wound or break in the skin (open fracture).
• 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 confirm the fracture type, displacement, and healing status. Documentation of the open fracture type (IIIA, IIIB, or IIIC) and routine healing progress is essential for accurate coding.

Treatment Options

Treatment may include immobilization with a cast or brace, pain management, and monitoring for infection. Surgical intervention may be required for severe open fractures. Physical therapy supports recovery and restores mobility as healing progresses.

Prognosis and Follow-Up

With routine healing, most patients recover fully, though recovery time varies. Follow-up appointments monitor healing, assess for complications, and guide rehabilitation. Long-term outcomes depend on fracture severity and adherence to treatment plans.

Complications

• Infection at the fracture site.
• Delayed or nonunion of the fracture.
• Nerve or vascular damage.
• Chronic pain or stiffness.
• Post-traumatic arthritis.

Lifestyle & Prevention

• Maintain bone health through diet and exercise.
• Use protective gear during high-risk activities.
• Address fall risks, especially in older adults.
• Avoid smoking, which impairs bone healing.
• Follow post-injury activity restrictions.

When to Seek Professional Help

Seek immediate care for severe pain, swelling, or signs of infection (e.g., fever, redness). Contact a healthcare provider if healing stalls or new symptoms (e.g., numbness, deformity) develop.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC) and confirm routine healing to support this code. Ensure the encounter is classified as "subsequent" and specify the left femur shaft location. Include details of the open fracture and healing status for accurate coding.
