S82.461C Displaced segmental fracture of shaft of right fibula, initial encounter for open fracture type IIIA, IIIB, or IIIC

Name of the Condition

• Displaced segmental fracture of shaft of right fibula, initial encounter for open fracture type IIIA, IIIB, or IIIC
• ICD-10 Code: S82.461C

Summary

A displaced segmental fracture of the shaft of the right fibula is a break in the long, thin bone on the lateral side of the lower leg, where the bone is broken into two or more separate pieces and the fragments are 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 broken, and the fracture is exposed. The "initial encounter" designation indicates this is the first time the patient is receiving treatment for this specific injury.

Causes

Most commonly caused by high-energy trauma, such as motor vehicle accidents, falls from significant height, or direct impact to the leg. Open fractures often result from severe trauma where the bone pierces the skin or external forces damage the soft tissue and bone simultaneously. Twisting injuries or forceful rotational forces can also lead to this type of fracture.

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.
• High-velocity trauma exposure, such as in certain occupations or accidents.

Symptoms

• Intense pain and swelling in the lower leg.
• Difficulty bearing weight on the affected leg.
• Bruising or tenderness around the injured area.
• Visible wound or open fracture site (for open fractures).
• Possible deformity or instability of the leg structure.
• Numbness or tingling if nerve involvement occurs.

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, deformity, and the presence of an open wound. Imaging tests, such as X-rays, are typically used to confirm the fracture and determine its extent and alignment. For open fractures, additional evaluation of soft tissue damage and potential contamination is necessary.

Treatment Options

• Immediate wound care and irrigation to reduce infection risk for open fractures.
• Surgical intervention, such as internal or external fixation, to stabilize the fracture and align the bone fragments.
• Antibiotics to prevent or treat infection in open fractures.
• Immobilization of the leg using a splint or cast to support healing.
• Pain management and monitoring for complications.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the extent of soft tissue damage, and the success of treatment. Open fractures carry a higher risk of infection and delayed healing. Follow-up care typically includes regular imaging to assess bone healing, physical therapy to restore function, and monitoring for signs of infection or nonunion.

Complications

• Infection at the fracture site or wound.
• Delayed healing or nonunion of the bone.
• Nerve or vascular damage.
• Chronic pain or instability.
• Post-traumatic arthritis in the ankle or knee.

Lifestyle & Prevention

• Use protective equipment during high-impact activities or sports.
• Maintain bone health through adequate calcium and vitamin D intake.
• Avoid high-risk situations that increase the likelihood of severe trauma.
• Follow post-injury rehabilitation guidelines to restore strength and mobility.

When to Seek Professional Help

Seek immediate medical attention if you experience severe leg pain, swelling, deformity, or an open wound after an injury. Prompt evaluation is critical for open fractures to reduce infection risk and ensure proper treatment.

Tips for Medical Coders

This code (S82.461C) is specific to a displaced segmental fracture of the right fibula with an open fracture type IIIA, IIIB, or IIIC, and it is used for the initial encounter. Documentation should clearly indicate the fracture type (segmental, displaced), the bone involved (right fibula), the fracture status (open), and the severity (IIIA, IIIB, or IIIC). Ensure the encounter is classified as "initial" and that later encounters for the same injury use appropriate follow-up codes.
