S72.333H Displaced oblique fracture of shaft of unspecified femur, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Displaced Oblique Fracture of Shaft of Unspecified Femur, Subsequent Encounter for Open Fracture Type I or II with Delayed Healing

Summary

A displaced oblique fracture of the shaft of the unspecified femur is a break in the long, central portion of the thigh bone where the fracture line runs at an angle, and the bone fragments are misaligned. This type of fracture involves the diaphysis (main structural part) of the femur and is classified as an open fracture (type I or II) during a subsequent encounter, indicating a break in the skin with minimal or moderate soft tissue damage. The "delayed healing" modifier indicates that the fracture has not progressed as expected during the normal healing timeline.

Causes

Such fractures often 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. Delayed healing may occur 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 infection risk and healing challenges.

Symptoms

• Persistent or worsening pain at the fracture site.
• Swelling, bruising, or tenderness around the fracture site.
• Inability to bear weight on the affected leg.
• Visible deformity or shortening of the leg (due to displacement).
• Possible numbness or tingling if nerve involvement occurs.
• Delayed healing may present as lack of visible progress in imaging or prolonged pain.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays to evaluate fracture alignment and healing progress. Additional tests like CT scans or MRIs may be used to assess soft tissue damage or infection. Clinical evaluation of the open wound (type I or II) and assessment of healing timeline are critical.

Treatment Options

• Immobilization with a cast or brace to stabilize the fracture.
• Surgical intervention (e.g., internal fixation) if alignment is poor or healing is delayed.
• Antibiotics for open fractures to prevent infection.
• Pain management and physical therapy to restore function.
• Monitoring for signs of nonunion or malunion.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, patient health, and adherence to treatment. Delayed healing may require extended follow-up and additional interventions. Regular imaging and clinical assessments are necessary to monitor progress. Most patients can expect full recovery with proper care, though some may experience long-term mobility issues.

Complications

• Nonunion (failure of the bone to heal).
• Malunion (healing in an incorrect position).
• Infection, especially with open fractures.
• Nerve or vascular damage.
• Chronic pain or stiffness.
• Post-traumatic arthritis.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Maintain a healthy diet rich in calcium and vitamin D to support bone health.
• Use protective equipment during sports or high-risk activities.
• Follow rehabilitation guidelines to restore strength and mobility.
• Quit smoking, as it can impair bone healing.

When to Seek Professional Help

• Severe or worsening pain.
• Signs of infection (e.g., fever, redness, pus).
• Numbness, tingling, or loss of circulation in the leg.
• Inability to bear weight after treatment.
• Delayed healing concerns or lack of progress.

Tips for Medical Coders

This code is used for a subsequent encounter of a displaced oblique femur shaft fracture with open type I or II and delayed healing. Document the fracture type, encounter stage, and healing status clearly. Ensure the open fracture classification (type I or II) and delayed healing are supported by clinical notes. Follow ICD-10-CM guidelines for subsequent encounter coding and modifiers.
