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

Name of the Condition

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

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 delayed healing. The fracture involves the middle portion of the bone and does not involve displacement of the bone fragments, though the skin is penetrated, and soft tissue damage is significant.

Causes

This fracture typically results from direct trauma to the leg, such as a high-impact fall, motor vehicle accident, or sports injury, which causes the bone to shatter into several pieces while maintaining alignment. The open nature of the fracture indicates the force was sufficient to break the skin, and the classification as type IIIA, IIIB, or IIIC suggests substantial soft tissue damage. Delayed healing may occur due to factors like poor blood supply, infection, or inadequate initial treatment.

Risk Factors

• Participation in high-impact sports or activities
• Osteoporosis or other conditions that weaken bone density
• Advanced age, which may reduce bone strength
• Previous leg injuries or surgeries
• Open fracture type IIIA, IIIB, or IIIC, which increases healing complexity

Symptoms

• Persistent pain and tenderness along the fibula
• Swelling and bruising around the lower leg
• Difficulty bearing weight on the affected leg
• Visible wound from the open fracture
• Possible deformity or instability of the leg structure
• Delayed healing signs, such as prolonged pain or lack of progress in recovery

Diagnosis

Diagnosis involves a physical examination to assess tenderness, swelling, and deformity, along with evaluation of the open wound. Imaging tests, such as X-rays, are used to confirm the fracture and determine the number of bone fragments. Additional tests, like CT scans or MRIs, may be performed to assess soft tissue damage and healing progress. The classification of the open fracture (IIIA, IIIB, or IIIC) is determined based on the extent of soft tissue injury and contamination.

Treatment Options

• Surgical intervention to clean the wound, stabilize the fracture, and address soft tissue damage
• Antibiotics to prevent or treat infection
• Immobilization using a cast or external fixator to maintain bone alignment
• Pain management with medications
• Physical therapy to restore mobility and strength after healing progresses
• Monitoring for signs of delayed healing or complications

Prognosis and Follow-Up

Prognosis depends on the severity of the open fracture and the success of treatment. Delayed healing may require extended follow-up and additional interventions. Regular monitoring with imaging and clinical assessments is necessary to track progress. Most patients can expect a full recovery with proper treatment, though recovery time may be longer due to the complexity of the injury.

Complications

• Infection at the fracture site
• Nonunion or malunion of the fracture
• Nerve or blood vessel damage
• Chronic pain or stiffness
• Limited mobility or functional impairment

Lifestyle & Prevention

• Avoid high-impact activities until fully healed
• Use protective gear during sports or activities
• Maintain bone health through proper nutrition and exercise
• Follow post-treatment instructions carefully to support healing
• Attend all follow-up appointments to monitor progress

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or visible wound changes. Contact your healthcare provider if you notice signs of infection, such as redness, pus, or fever, or if healing does not progress as expected.

Tips for Medical Coders

This code is specific to a subsequent encounter for an open fracture of the left fibula shaft, classified as type IIIA, IIIB, or IIIC, with delayed healing. Documentation must clearly indicate the fracture type, the encounter type (subsequent), and evidence of delayed healing. Coders should verify that the open fracture classification aligns with the documented soft tissue damage and that the fibula shaft is the affected site.
