S82.426F Nondisplaced transverse fracture of shaft of unspecified fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing

Name of the Condition

• Nondisplaced transverse fracture of shaft of unspecified fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with routine healing
• ICD-10 Code: S82.426F

Summary

A nondisplaced transverse fracture of the shaft of the unspecified fibula is a break in the long, thin bone on the lateral side of the lower leg, where the fracture line runs horizontally across the middle portion of the bone. The bone fragments remain in their normal anatomical alignment, and the fracture is classified as open (type IIIA, IIIB, or IIIC) with routine healing. This is a subsequent encounter, indicating follow-up care after initial treatment. The term "unspecified" means the fibula is not identified as right or left.

Causes

Most commonly caused by direct trauma or high-impact forces to the leg, such as falls, sports injuries, or motor vehicle accidents. Open fractures may result from the same mechanisms, with the force sufficient to break the skin and expose the fracture site. Routine healing indicates the fracture is progressing as expected without complications.

Risk Factors

• Participation in contact sports or high-impact activities.
• Osteoporosis or reduced bone density, which increases fragility.
• Advanced age, which may weaken bone strength.
• Previous leg injuries or surgeries.
• Open fractures, which carry higher infection risk.

Symptoms

• 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.
• Signs of routine healing, such as reduced pain or improved mobility.

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. Documentation should specify the fracture type (IIIA, IIIB, or IIIC) and note routine healing. Follow-up visits may include assessing healing progress and functional recovery.

Treatment Options

Treatment focuses on maintaining alignment, promoting healing, and preventing infection. This may include immobilization with a cast or brace, pain management, and monitoring for complications. Open fractures may require wound care or antibiotics. Physical therapy is often recommended to restore strength and mobility once healing is established.

Prognosis and Follow-Up

Prognosis is generally favorable with routine healing, though recovery time varies. Follow-up care ensures the fracture heals properly and addresses any residual symptoms. Regular assessments may include imaging to confirm healing and functional evaluations to guide rehabilitation.

Complications

• Infection, particularly with open fractures.
• Delayed healing or nonunion.
• 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.
• Use protective gear during sports or activities.
• Maintain bone health through diet and exercise.
• Follow post-injury care instructions to support healing.
• Report any new or worsening symptoms promptly.

When to Seek Professional Help

Seek immediate care if experiencing severe pain, swelling, or signs of infection (e.g., fever, redness, drainage). Contact a healthcare provider if symptoms worsen or do not improve with treatment, or if there is difficulty bearing weight or moving the leg.

Tips for Medical Coders

Document the fracture type (IIIA, IIIB, or IIIC) and confirm routine healing to support this code. Ensure the encounter is classified as subsequent and that the fibula is unspecified. Include details on treatment progress and any complications to justify the code selection.
