S72.335G Nondisplaced oblique fracture of shaft of left femur, subsequent encounter for closed fracture with delayed healing

Name of the Condition

• Nondisplaced Oblique Fracture of Shaft of Left Femur, Subsequent Encounter for Closed Fracture with Delayed Healing

Summary

A nondisplaced oblique fracture of the shaft of the left 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 remain aligned. This type of fracture involves the diaphysis (main structural part) of the femur and is classified as closed, meaning the overlying skin is intact. The subsequent encounter indicates ongoing care for the injury, and the delayed healing modifier specifies that the fracture is not progressing as expected within the typical timeframe for recovery.

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, inadequate immobilization, or underlying health conditions affecting bone repair.

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.
• Smoking, diabetes, or other systemic conditions that impair healing.

Symptoms

• Persistent or worsening pain at the fracture site.
• Swelling, bruising, or tenderness that does not resolve.
• Inability to bear weight on the affected leg.
• Possible limited range of motion in the hip or knee.
• Delayed or absent signs of healing on follow-up imaging.

Diagnosis

Physical examination to assess pain, alignment, and function. Imaging tests such as X-rays to evaluate fracture healing progress and check for signs of delayed union. Additional tests (e.g., CT or MRI) may be used to assess bone density or identify underlying issues contributing to poor healing.

Treatment Options

• Continued immobilization (e.g., casting or bracing) to support healing.
• Pain management with medications or physical therapy.
• Surgical intervention (e.g., internal fixation) if healing does not improve with conservative measures.
• Nutritional support or supplements to promote bone health.
• Addressing underlying conditions (e.g., managing diabetes or osteoporosis) that may hinder recovery.

Prognosis and Follow-Up

Prognosis depends on the cause of delayed healing and response to treatment. Most fractures eventually heal with appropriate care, but recovery may take longer than usual. Regular follow-up appointments and imaging are necessary to monitor progress. Physical therapy may be recommended to restore strength and mobility once healing is confirmed.

Complications

• Nonunion (failure of the fracture to heal).
• Malunion (healing in an incorrect position).
• Chronic pain or stiffness.
• Infection (if surgical intervention is required).
• Nerve or vascular damage (rare but possible).

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 and limit alcohol, as both can impair healing.
• Use protective gear during sports or activities with fall risks.
• Address underlying health conditions that may affect bone strength.

When to Seek Professional Help

• Increasing pain, swelling, or bruising at the fracture site.
• Inability to bear weight or use the leg after initial improvement.
• Signs of infection (e.g., redness, warmth, fever).
• Numbness, tingling, or weakness in the leg or foot.
• Lack of healing progress noted on follow-up imaging.

Tips for Medical Coders

This code (S72.335G) is used for a subsequent encounter for a closed, nondisplaced oblique fracture of the left femur shaft with delayed healing. Documentation should specify the fracture type, laterality, encounter stage (subsequent), and the presence of delayed healing. Ensure the record includes details about the fracture’s status, treatment provided, and any factors contributing to the delayed healing to support accurate coding.
