S72.326H Nondisplaced transverse fracture of shaft of unspecified femur, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Nondisplaced Transverse Fracture of Shaft of Unspecified Femur, Subsequent Encounter for Open Fracture Type I or II with Delayed Healing (ICD-10 Code: S72.326H)

Summary

A nondisplaced transverse fracture of the femur shaft is a break in the long, central portion of the thigh bone where the fracture line runs horizontally across the bone, and the bone fragments remain aligned without separation. This type of fracture involves the diaphysis (main structural part) of the femur and may be associated with soft tissue injury or instability, though displacement is absent. The code S72.326H specifies a subsequent encounter for an open fracture type I or II with delayed healing, indicating the fracture communicates with the external environment through a skin wound (typically small and clean) and healing is progressing slower than expected.

Causes

Such fractures typically result from high-impact trauma, such as motor vehicle accidents, falls from significant heights, or direct blows to the thigh. Rotational forces or axial loading (e.g., during sports or industrial injuries) can also cause this type of break. Open fractures occur when the trauma is severe enough to pierce the skin, exposing the fracture site to the external environment. Delayed healing may result from 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.
• Poor nutrition or smoking, which can impair bone healing.

Symptoms

• Persistent or worsening pain at the fracture site.
• Swelling, bruising, or tenderness around the fracture area.
• Inability to bear weight on the affected leg.
• Possible drainage or signs of infection if the wound is open.
• Delayed healing may present as prolonged pain or lack of progress in recovery.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests, such as X-rays or CT scans, to confirm the fracture type, assess healing progress, and rule out complications like infection or nonunion. Evaluation of the open wound (if present) to determine type and risk of infection. Blood tests may be used to check for signs of infection or nutritional deficiencies affecting healing.

Treatment Options

Treatment focuses on promoting healing and managing the open fracture. This may include immobilization with a cast or brace, surgical intervention to stabilize the fracture (e.g., internal fixation), wound care to prevent infection, and antibiotics if infection is suspected. Pain management and physical therapy may be recommended to restore function. Delayed healing may require additional interventions, such as bone grafting or prolonged immobilization.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the patient’s overall health, and adherence to treatment. Most nondisplaced fractures heal with proper care, but delayed healing may extend recovery time. Regular follow-up appointments are necessary to monitor healing progress, adjust treatment, and address complications. Physical therapy is often recommended to restore strength and mobility once healing is underway.

Complications

• Infection at the fracture site or open wound.
• Nonunion (failure of the bone to heal).
• Malunion (healing in an incorrect position).
• Nerve or blood vessel damage.
• Chronic pain or reduced mobility.
• Delayed healing, which may require additional interventions.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking, as it impairs bone healing.
• Use protective gear during sports or activities with a risk of injury.
• Follow post-treatment instructions carefully to promote proper healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or drainage from the wound, signs of infection (e.g., fever, redness), or if the fracture site feels unstable. Contact your healthcare provider if pain worsens or does not improve with treatment, or if you notice delayed healing.

Tips for Medical Coders

Document the fracture type (nondisplaced transverse), location (shaft of unspecified femur), encounter type (subsequent), open fracture classification (type I or II), and delayed healing. Ensure the open wound is described as clean or contaminated to support the code. Note any contributing factors to delayed healing, such as infection or poor blood supply, to justify the code’s specificity.
