S82.464J Nondisplaced segmental fracture of shaft of right fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing

Name of the Condition

• Nondisplaced segmental fracture of shaft of right fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing
• ICD-10 Code: S82.464J

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 IIIA, IIIB, or IIIC, indicating significant skin and soft tissue damage. The "subsequent encounter" designation applies to follow-up care, and "delayed healing" signifies that the fracture has not progressed as expected during the normal healing timeline.

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 may occur due to infection, poor blood supply, 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).
• Poor nutrition or smoking, which can impair healing.

Symptoms

• Intense pain and swelling in the lower leg.
• 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.
• Visible wound or open area if the fracture is open.
• Prolonged healing time or lack of progress in recovery.

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, and wound characteristics. Imaging studies, such as X-rays or CT scans, are used to confirm the fracture type and assess alignment. Laboratory tests may be ordered to check for infection or nutritional deficiencies. Documentation of the fracture type (IIIA, IIIB, or IIIC) and healing status is critical for accurate coding.

Treatment Options

Treatment focuses on stabilizing the fracture and promoting healing. This may include immobilization with a cast or brace, surgical intervention to clean the wound and stabilize the bone, and antibiotics to treat or prevent infection. Physical therapy is often recommended to restore strength and mobility once healing progresses. Nutritional support and smoking cessation may be advised to enhance healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the presence of infection, and adherence to treatment. Delayed healing may require extended follow-up and additional interventions. Regular monitoring with imaging and clinical assessments is necessary to track progress. Most patients can expect a full recovery with proper care, though some may experience residual stiffness or weakness.

Complications

• Infection at the fracture site or wound.
• Nonunion or malunion of the fracture.
• Nerve or vascular damage.
• Chronic pain or instability.
• Limited mobility or functional impairment.

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-treatment instructions carefully to optimize recovery.

When to Seek Professional Help

Seek immediate medical attention if you experience increased pain, swelling, redness, or drainage from the wound; signs of infection (e.g., fever, chills); or sudden loss of sensation or movement in the leg. 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 (IIIA, IIIB, or IIIC) and the presence of delayed healing to support the S82.464J code. Ensure the encounter is classified as "subsequent" and that the open fracture details are clearly recorded. Include any relevant clinical notes about healing status, treatment interventions, or complications to justify the code selection.
