S82.465C Nondisplaced segmental fracture of shaft of left fibula, initial encounter for open fracture type IIIA, IIIB, or IIIC

Name of the Condition

• Nondisplaced segmental fracture of shaft of left fibula, initial encounter for open fracture type IIIA, IIIB, or IIIC
• ICD-10 Code: S82.465C

Summary

A nondisplaced segmental fracture of the shaft of the left fibula is a break in the long, thin bone of the lower leg, where the bone is fractured at two separate sites along the same segment, creating a middle fragment that remains in its original position without displacement. This type of fracture is classified as stable due to the maintained alignment of the bone fragments. The "open fracture" designation indicates that the fracture has broken through the skin, exposing the bone, and is categorized as type IIIA, IIIB, or IIIC based on the severity of soft tissue damage and contamination. This is the initial encounter 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. Twisting injuries or severe rotational forces can also lead to this type of fracture. The open nature of the fracture typically results from the trauma being forceful enough to pierce the skin.

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.
• Situations with high risk of severe trauma, such as motor vehicle collisions.

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 bone protrusion or open wound at the fracture site (due to the open fracture type).

Diagnosis

Diagnosis involves a physical examination by a healthcare professional to assess tenderness, swelling, and deformity. Imaging tests, such as X-rays, are typically used to confirm the fracture and determine its extent and alignment. The open wound is evaluated to classify the fracture as type IIIA, IIIB, or IIIC based on the severity of soft tissue damage and contamination. Additional tests may be performed to assess nerve or vascular involvement.

Treatment Options

• Immediate wound care and irrigation to reduce infection risk.
• Surgical intervention to stabilize the fracture, often involving internal or external fixation.
• Antibiotics to prevent infection due to the open nature of the fracture.
• Pain management and immobilization with a cast or brace.
• Physical therapy to restore function and strength after healing.

Prognosis and Follow-Up

Prognosis depends on the severity of the open fracture and the effectiveness of treatment. Nondisplaced fractures generally heal well with proper care, but open fractures carry a higher risk of infection and complications. Follow-up appointments are necessary to monitor healing, assess for infection, and adjust treatment as needed. Physical therapy is often recommended to restore mobility and strength.

Complications

• Infection at the fracture site due to the open wound.
• Delayed healing or nonunion of the fracture.
• Nerve or vascular damage from the initial trauma.
• Chronic pain or instability in the leg.
• Post-traumatic arthritis in the surrounding joints.

Lifestyle & Prevention

• Use protective gear during high-risk activities, such as sports or construction work.
• Maintain bone health through a diet rich in calcium and vitamin D.
• Avoid activities that increase the risk of falls or direct trauma to the legs.
• Follow post-injury care instructions carefully to promote proper healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or an open wound after a leg injury. Signs of infection, such as increased redness, pus, or fever, also require prompt evaluation. Difficulty bearing weight or numbness in the foot should be addressed by a healthcare professional.

Tips for Medical Coders

Document the fracture as nondisplaced and segmental, specifying the left fibula. Note the open fracture type (IIIA, IIIB, or IIIC) and confirm it is the initial encounter. Ensure the wound characteristics and severity are clearly documented to support the open fracture classification. Verify that the fracture is not displaced to avoid miscoding.
