S82.464H Nondisplaced segmental fracture of shaft of right fibula, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Nondisplaced segmental fracture of shaft of right fibula, subsequent encounter for open fracture type I or II with delayed healing
• ICD-10 Code: S82.464H

Summary

A nondisplaced segmental fracture of the shaft of the right fibula is a break in the long, thin bone of the lower leg involving two separate fracture sites along the same bone segment, with the fragments remaining in alignment. This injury is classified as an open fracture type I or II, meaning the overlying skin is compromised but the wound is typically small and clean. The "subsequent encounter" designation indicates this is a follow-up visit for treatment, and "delayed healing" signifies that the fracture is not progressing as expected toward union within the typical timeframe.

Causes

Most commonly caused by high-energy trauma, such as motor vehicle accidents, falls from significant height, or direct impact to the leg. Twisting injuries or severe rotational forces can also lead to this type of fracture. Open fractures may result from the trauma piercing the skin or from a pre-existing wound becoming contaminated. Delayed healing can occur due to factors like poor blood supply, infection, or inadequate immobilization.

Risk Factors

• Participation in high-impact sports or activities with risk of falls.
• Osteoporosis or reduced bone density, which increases fragility.
• Advanced age, which may weaken bone strength.
• Previous leg injuries or surgeries that compromise bone integrity.
• Exposure to environments with increased risk of trauma (e.g., construction sites).
• Conditions that impair healing, such as diabetes or smoking.

Symptoms

• Persistent pain and swelling in the lower leg beyond the expected healing period.
• Difficulty bearing weight on the affected leg.
• Bruising or tenderness around the injured area.
• Possible deformity or instability of the leg structure.
• Numbness or tingling if nerve involvement occurs.
• Delayed or absent signs of bone healing on imaging.

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, and stability. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture type, assess alignment, and evaluate healing progress. Additional tests, like blood work or wound cultures, may be performed to rule out infection or other complications contributing to delayed healing.

Treatment Options

Treatment focuses on promoting healing and may include immobilization with a cast or brace to stabilize the fracture. Surgical intervention, such as internal fixation, may be considered if the fracture shows no progress. Antibiotics are prescribed for open fractures to prevent infection. Pain management and physical therapy are also part of the care plan to restore function and strength.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the presence of complications, and adherence to treatment. Delayed healing may extend recovery time, requiring closer monitoring. Follow-up visits are essential to assess healing through imaging and adjust treatment as needed. Most patients eventually regain full function, but recovery may take longer than with uncomplicated fractures.

Complications

• Infection at the fracture site or wound.
• Nonunion, where the bone fails to heal properly.
• Malunion, resulting in improper alignment.
• Nerve or vascular damage.
• Chronic pain or stiffness.
• Reduced mobility or function.

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 healing.
• Use protective gear during sports or activities with fall risks.
• Follow post-injury care instructions closely to promote healing.

When to Seek Professional Help

Seek immediate medical attention if you experience increased pain, swelling, redness, or drainage from the wound, signs of infection, or new numbness or weakness. Contact your healthcare provider if healing does not progress as expected or if you have concerns about your recovery.

Tips for Medical Coders

Document the fracture type (open I or II), the encounter type (subsequent), and the presence of delayed healing clearly in the medical record. Ensure the code S82.464H is used only when the fracture is nondisplaced, segmental, involves the right fibula, is open type I or II, and is being treated during a subsequent encounter with documented delayed healing. Verify that all components of the code are supported by clinical findings and treatment notes.
