S82.455N Nondisplaced comminuted fracture of shaft of left fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Name of the Condition

• Nondisplaced comminuted fracture of shaft of left fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion
• ICD-10-CM Code: S82.455N

Summary

A nondisplaced comminuted fracture of the shaft of the left fibula is a bone injury where the fibula is broken into multiple pieces but remains in its normal anatomical alignment. This code applies to a subsequent encounter for an open fracture classified as type IIIA, IIIB, or IIIC, with nonunion (failure of the bone to heal properly). The fracture involves the middle portion of the left fibula and is associated with significant soft tissue damage and delayed healing.

Causes

This fracture typically results from high-impact trauma to the leg, such as a motor vehicle accident, fall, or severe sports injury, which causes the bone to shatter into multiple fragments while maintaining alignment. The open nature of the fracture (types IIIA, IIIB, or IIIC) indicates extensive soft tissue damage, and nonunion suggests the bone has not healed after an extended period.

Risk Factors

• High-impact activities or occupations
• Osteoporosis or other bone-weakening conditions
• Advanced age, which may reduce bone density
• Previous leg injuries or surgeries
• Poor blood supply to the fracture site

Symptoms

• Persistent pain and tenderness along the fibula
• Swelling and bruising around the lower leg
• Difficulty bearing weight on the affected leg
• Visible wound or open fracture site
• Possible instability or deformity of the leg

Diagnosis

Diagnosis involves a physical examination to assess tenderness, swelling, and wound characteristics. Imaging tests, such as X-rays or CT scans, are used to confirm the fracture pattern, assess nonunion, and evaluate soft tissue damage. Additional tests may be performed to rule out infection or assess bone healing.

Treatment Options

• Surgical intervention to stabilize the fracture and promote healing (e.g., internal fixation)
• Wound care for open fracture sites to prevent infection
• Pain management with medications
• Physical therapy to restore mobility and strength
• Monitoring for signs of infection or further complications

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, soft tissue damage, and response to treatment. Nonunion may require additional interventions, such as bone grafting or revision surgery. Regular follow-up appointments are necessary to monitor healing and adjust treatment plans as needed.

Complications

• Infection at the fracture site
• Delayed or failed healing (nonunion)
• Nerve or blood vessel damage
• Chronic pain or instability
• Post-traumatic arthritis

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Maintain a healthy diet rich in calcium and vitamin D to support bone health
• Use protective equipment during sports or high-risk activities
• Follow prescribed rehabilitation plans to optimize recovery

When to Seek Professional Help

Seek immediate medical attention if experiencing severe pain, swelling, or signs of infection (e.g., fever, redness, or drainage from the wound). Contact a healthcare provider if symptoms worsen or do not improve with treatment.

Tips for Medical Coders

This code is specific to a subsequent encounter for an open fracture of the left fibula with nonunion, classified as type IIIA, IIIB, or IIIC. Documentation should clearly indicate the fracture type, nonunion status, and that this is a subsequent encounter. Ensure alignment with clinical notes and coding guidelines to accurately reflect the condition.
