S82.455H Nondisplaced comminuted fracture of shaft of left fibula, subsequent encounter for open fracture type I or II with delayed healing

Name of the Condition

• Nondisplaced comminuted fracture of shaft of left fibula, subsequent encounter for open fracture type I or II with delayed healing
• ICD-10-CM Code: S82.455H

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 is an open fracture (type I or II), meaning the skin is penetrated with minimal soft tissue damage. The term "subsequent encounter" indicates this is a follow-up visit for the fracture, and "delayed healing" signifies that the fracture has not progressed as expected during the normal healing timeline.

Causes

This fracture typically results from direct trauma to the leg, such as a 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 suggests the force was sufficient to break the skin, though the soft tissue damage is limited in type I or II cases. Delayed healing may occur due to factors like poor blood supply, infection, or inadequate immobilization.

Risk Factors

• Participation in high-impact sports or activities
• Osteoporosis or conditions that weaken bone density
• Advanced age, which may reduce bone strength
• Previous leg injuries or surgeries
• Smoking or poor nutrition, which can impair healing

Symptoms

• Persistent pain and tenderness along the fibula
• Swelling and bruising around the lower leg
• Difficulty bearing weight on the affected leg
• Possible deformity or instability of the leg structure
• Visible wound (if open fracture)
• Prolonged healing time beyond the expected duration

Diagnosis

Diagnosis involves a physical examination to assess tenderness, swelling, and deformity. Imaging tests, such as X-rays, are typically used to confirm the fracture and determine the number of bone fragments. Additional tests, like CT scans or MRIs, may be ordered to evaluate soft tissue damage or assess healing progress. The presence of an open wound and delayed healing will guide further evaluation.

Treatment Options

• Immobilization using a cast or brace to maintain bone alignment
• Pain management with medications
• Wound care for open fractures to prevent infection
• Physical therapy to restore mobility and strength after immobilization
• Surgical intervention (e.g., internal fixation) if healing does not progress
• Monitoring for signs of infection or nonunion

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the patient’s overall health, and adherence to treatment. Most fractures heal with proper care, but delayed healing may require extended follow-up. Regular imaging and clinical assessments are necessary to monitor progress. Follow-up visits will focus on assessing healing, managing symptoms, and adjusting treatment as needed.

Complications

• Nonunion (failure of the bone to heal)
• Infection, especially with open fractures
• Malunion (healing in an abnormal position)
• Chronic pain or instability
• Nerve or blood vessel damage
• Prolonged disability or reduced mobility

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Maintain a balanced diet rich in calcium and vitamin D to support bone health
• Quit smoking, as it impairs healing
• Use protective gear during sports or activities
• Follow post-injury care instructions closely to promote healing

When to Seek Professional Help

Seek immediate medical attention if you experience:

• Severe pain that worsens over time
• Increased swelling, redness, or drainage from the wound
• Fever or signs of infection
• Numbness or tingling in the leg or foot
• Inability to bear weight on the affected leg
• New deformity or instability

Tips for Medical Coders

When coding S82.455H, ensure documentation supports:

• Nondisplaced comminuted fracture of the left fibula shaft
• Open fracture type I or II (skin penetration with minimal soft tissue damage)
• Subsequent encounter (follow-up visit, not initial treatment)
• Delayed healing (evidence of prolonged healing timeline or lack of progress)
• Specificity of the left fibula and fracture type is critical for accurate coding.
