S82.463F Displaced segmental fracture of shaft of unspecified fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Displaced segmental fracture of shaft of unspecified fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
• ICD-10 Code: S82.463F

Summary

A displaced segmental fracture of the shaft of the unspecified fibula is a break in the long, thin bone of the lower leg, where the bone is fractured into two or more separate pieces with the fragments out of alignment. This injury involves the middle portion of the fibula and is classified as an open fracture (type IIIA, IIIB, or IIIC), meaning the skin is breached and the wound is more severe. The term "subsequent encounter" indicates this is a follow-up visit for care after the initial treatment, and "routine healing" denotes that the fracture is progressing as expected without complications.

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 same mechanisms, with the bone piercing the skin or the trauma causing an external wound.

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.

Symptoms

• Pain and swelling in the lower leg, though typically less severe than during the initial injury.
• Possible residual bruising or tenderness around the injured area.
• Difficulty bearing weight on the affected leg, depending on healing progress.
• Visible signs of the previous open wound, if still present.

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, and alignment. Imaging tests, such as X-rays, are typically used to confirm the fracture's status and ensure routine healing. Documentation of the open fracture type (IIIA, IIIB, or IIIC) and the subsequent encounter context is critical for accurate coding.

Treatment Options

• Monitoring of healing progress through regular follow-up visits.
• Pain management as needed, often with over-the-counter or prescription medications.
• Physical therapy to restore strength and mobility once healing allows.
• Continued wound care if residual open areas remain, though routine healing suggests minimal intervention.

Prognosis and Follow-Up

With routine healing, the prognosis is generally favorable, though recovery time varies based on fracture severity and individual health. Follow-up care focuses on ensuring the fracture heals properly and addressing any residual functional limitations. Most patients regain full or near-full mobility with appropriate rehabilitation.

Complications

• Delayed healing or nonunion, though routine healing reduces this risk.
• Persistent pain or stiffness in the lower leg.
• Residual soft tissue damage from the initial open fracture.
• Infection, though less likely with routine healing.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use protective gear during sports or activities with fall risks.
• Maintain bone health through a balanced diet and regular exercise.
• Follow post-injury guidelines to support healing and prevent re-injury.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or new symptoms (e.g., fever, redness, or drainage from the wound) develop. These may indicate complications requiring prompt attention.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC) and confirm the encounter is subsequent (not initial) with evidence of routine healing. Ensure the fibula is unspecified (side not documented) and the fracture is segmental and displaced. Code S82.463F applies only when the open fracture type and healing status are clearly documented.
