S72.355H Nondisplaced comminuted fracture of shaft of left femur, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Nondisplaced comminuted fracture of shaft of left femur, subsequent encounter for open fracture type I or II with delayed healing (ICD-10 Code: S72.355H)

Summary

This condition involves a fracture of the left 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 left femur 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, meaning the patient is receiving follow-up care for the injury, and healing is delayed.

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. Delayed healing may result from factors like poor blood supply, infection, or inadequate immobilization.

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.
• Poor nutrition or smoking, which can impair healing.

Symptoms

• Persistent pain at the fracture site, even with immobilization.
• Swelling, bruising, or tenderness that does not improve over time.
• Inability to bear weight on the affected leg.
• Possible visible wound or break in the skin (from the open fracture).
• Delayed or incomplete healing observed on imaging.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays or CT scans to evaluate fracture healing and bone alignment. Assessment of the open wound for signs of infection or contamination. Review of prior treatment and immobilization methods to identify potential barriers to healing.

Treatment Options

• Continued immobilization with a cast or brace to support the fracture.
• Wound care for the open fracture site to prevent infection.
• Pain management with medications as needed.
• Possible surgical intervention if healing does not progress, such as bone grafting or internal fixation.
• Physical therapy to maintain mobility and strength during recovery.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the patient’s overall health, and adherence to treatment. Delayed healing may extend recovery time, requiring ongoing monitoring. Follow-up appointments with imaging to assess progress are essential. Most patients eventually regain function, but recovery may be prolonged.

Complications

• Infection at the open fracture site.
• Nonunion (failure of the bone to heal).
• Malunion (healing in an incorrect position).
• Chronic pain or stiffness.
• Nerve or vascular damage from the initial trauma.

Lifestyle & Prevention

• Avoid high-impact activities until fully healed.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking, as it impairs healing.
• Use protective gear during activities with a risk of falls or trauma.
• Follow post-injury care instructions closely to promote healing.

When to Seek Professional Help

• Increasing pain, swelling, or redness at the fracture site.
• Signs of infection, such as fever, pus, or foul odor from the wound.
• Numbness, tingling, or loss of circulation in the leg.
• Inability to bear weight after a period of immobilization.
• No improvement in healing after several weeks of treatment.

Tips for Medical Coders

Document the fracture type (open I or II), the fact that this is a subsequent encounter, and the presence of delayed healing. Include details on the fracture’s location (shaft of left femur), displacement status (nondisplaced), and comminution. Note any contributing factors to delayed healing, such as infection or poor immobilization, to support code specificity.
