S72.325H Nondisplaced transverse fracture of shaft of left femur, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Nondisplaced Transverse Fracture of Shaft of Left Femur, Subsequent Encounter for Open Fracture Type I or II with Delayed Healing (ICD-10 Code: S72.325H)

Summary

A nondisplaced transverse fracture of the shaft of the left femur is a break in the long, central portion of the left thigh bone, where the fracture line runs horizontally across the bone and the bone fragments remain aligned. This type of fracture involves the diaphysis (main structural part) of the femur and is classified as an open fracture type I or II, indicating a break in the skin with minimal contamination or soft tissue damage. The "subsequent encounter" designation indicates ongoing care for the fracture, and "delayed healing" signifies that the fracture has not progressed as expected during the normal healing timeline.

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 (e.g., during sports or industrial accidents) can also cause this type of break. Open fractures occur when the bone pierces the skin or when external forces disrupt the soft tissue overlying the fracture site. Delayed healing may be due to factors like poor blood supply, infection, or inadequate immobilization.

Risk Factors

• Participation in high-impact sports or activities.
• Osteoporosis or other bone-weakening conditions.
• Advanced age, due to decreased bone density.
• Prior history of fractures or bone abnormalities.
• Trauma or accidents involving significant force.
• Open fracture type I or II, which may increase healing time.

Symptoms

• Persistent or worsening pain at the fracture site.
• Swelling, bruising, or tenderness around the affected area.
• Inability to bear weight on the left leg.
• Possible numbness or tingling if nerve involvement occurs.
• Delayed healing signs, such as lack of visible bone union on imaging.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests, such as X-rays or CT scans, to confirm the fracture type, displacement, and healing progress. Evaluation of the open wound (if present) to determine contamination or infection risk. Assessment of healing status through serial imaging to identify delayed union.

Treatment Options

• Immobilization with a cast or brace to stabilize the fracture.
• Surgical intervention, if needed, to address open wounds or promote healing.
• Antibiotics to prevent or treat infection in open fractures.
• Pain management with medications or other therapies.
• Physical therapy to restore strength and mobility once healing allows.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, adherence to treatment, and individual healing capacity. Subsequent encounters involve monitoring healing progress through imaging and clinical assessments. Follow-up care may include adjustments to immobilization, wound care for open fractures, and rehabilitation to restore function. Delayed healing may require extended treatment or additional interventions.

Complications

• Infection at the fracture site or open wound.
• Nonunion (failure of the bone to heal).
• Malunion (improper healing leading to misalignment).
• Nerve or vascular damage.
• Chronic pain or reduced mobility.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Follow weight-bearing restrictions as advised.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Use protective equipment during sports or high-risk activities.
• Address underlying conditions like osteoporosis to reduce fracture risk.

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 you notice signs of infection (e.g., redness, pus, fever) or if healing does not progress as expected. Follow up with your provider for scheduled assessments to monitor healing.

Tips for Medical Coders

Document the fracture type (open I or II), laterality (left femur), and healing status (delayed) clearly in the medical record. Use the "subsequent encounter" code (S72.325H) when reporting follow-up care for an open fracture with delayed healing. Ensure documentation supports the open fracture classification and delayed healing to justify the code selection.
