S82.401M Unspecified fracture of shaft of right fibula, subsequent encounter for open fracture type I or II with nonunion

Name of the Condition

• Unspecified fracture of shaft of right fibula, subsequent encounter for open fracture type I or II with nonunion
• ICD-10 Code: S82.401M

Summary

This condition refers to a fracture (break) of the middle portion of the fibula, the smaller bone in the lower leg, on the right side. The term "unspecified" indicates the exact location of the fracture on the fibula has not been detailed. It is an open fracture (type I or II), meaning the bone breaks through the skin, and this is a subsequent medical encounter for the injury. The fracture has not healed (nonunion) during previous treatment.

Causes

Most commonly caused by direct trauma or impact to the outside of the leg, such as from falls, sports injuries, or accidents. Open fractures may result from higher-energy injuries that penetrate the skin. Nonunion can occur due to inadequate immobilization, poor blood supply, infection, or severe displacement of the bone fragments.

Risk Factors

• Participation in contact sports or high-impact activities.
• High-risk occupations or environments increasing fall or injury likelihood.
• Osteoporosis or reduced bone density, which weakens bone strength.
• Advanced age, which may compromise bone integrity.
• Poor nutrition or smoking, which can impair bone healing.

Symptoms

• Persistent pain and swelling in the lower leg.
• Difficulty bearing weight on the leg.
• Bruising or tenderness around the injured area.
• Visible wound or break in the skin at the fracture site.
• Possible deformity or instability of the leg structure.
• Lack of healing progress over time (nonunion).

Diagnosis

Physical examination by a healthcare professional to assess tenderness, swelling, and deformity. Imaging tests, such as X-rays or CT scans, are used to confirm the fracture, assess alignment, and evaluate for nonunion. Additional tests may be ordered to check for infection or poor blood supply.

Treatment Options

• Surgical intervention to realign and stabilize the bone, often with plates, screws, or bone grafts.
• Immobilization with a cast or external fixator to support healing.
• Antibiotics if infection is present.
• Pain management with medications such as analgesics.
• Physical therapy to restore strength and mobility once healing progresses.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the success of treatment, and patient factors like age and overall health. Follow-up appointments are necessary to monitor healing and adjust treatment. Nonunion may require additional procedures if initial treatment is unsuccessful.

Complications

• Infection at the fracture site.
• Nerve or blood vessel damage.
• Chronic pain or arthritis.
• Delayed or failed healing (nonunion).
• Leg length discrepancy or deformity.

Lifestyle & Prevention

• Avoid high-impact activities until fully healed.
• Use protective gear during sports or work.
• Maintain a balanced diet rich in calcium and vitamin D to support bone health.
• Quit smoking, as it impairs bone healing.
• Follow post-treatment instructions carefully to promote recovery.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, visible bone protrusion, or signs of infection (e.g., fever, redness, pus). Contact your healthcare provider if pain persists or worsens after treatment, or if you notice no improvement in healing over time.

Tips for Medical Coders

This code is used for a subsequent encounter of an open fracture (type I or II) of the right fibula shaft with nonunion. Document the encounter type (subsequent), fracture type (open I or II), and nonunion status clearly. Ensure the right fibula and shaft location are specified, and note any contributing factors like infection or poor healing.
