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

Name of the Condition

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

Summary

A nondisplaced comminuted fracture of the shaft of the left fibula is a bone injury where the fibula (the smaller lower leg bone) 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 routine healing. The term "subsequent encounter" indicates ongoing care after the initial treatment phase, and "routine healing" signifies the fracture is progressing without complications.

Causes

This fracture typically results from direct trauma to the leg, such as a high-impact injury from a fall, motor vehicle accident, or sports-related incident. The force causes the bone to shatter into several pieces while maintaining alignment. The open nature of the fracture (types IIIA, IIIB, or IIIC) involves significant soft tissue damage, often from the initial trauma.

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

Symptoms

• 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 if alignment is compromised

Diagnosis

Diagnosis involves a physical examination to assess tenderness, swelling, and wound characteristics. Imaging tests, such as X-rays, are used to confirm the fracture type and healing status. The classification of the open fracture (IIIA, IIIB, or IIIC) is determined by the extent of soft tissue damage and contamination.

Treatment Options

• Immobilization using a cast or brace to maintain alignment during healing
• Wound care to manage the open fracture and prevent infection
• Pain management with medications
• Physical therapy to restore mobility and strength after immobilization
• Monitoring for signs of infection or delayed healing

Prognosis and Follow-Up

With routine healing, the prognosis is generally favorable, though recovery time may vary. Follow-up care focuses on assessing healing progress, managing any residual symptoms, and guiding rehabilitation. Regular imaging may be used to confirm bone union and soft tissue recovery.

Complications

• Infection at the wound site
• Delayed or nonunion of the fracture
• Nerve or vascular damage from the initial trauma
• Chronic pain or instability

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider
• Use protective gear during sports or activities with fall risks
• Maintain bone health through diet and exercise to reduce fracture risk
• Follow post-injury care instructions to support healing

When to Seek Professional Help

Seek immediate medical attention if there is increased pain, swelling, redness, or drainage from the wound, or if there are signs of infection (e.g., fever, chills). Contact a healthcare provider if mobility does not improve or if new symptoms develop.

Tips for Medical Coders

This code is specific to a subsequent encounter for an open fracture of the left fibula shaft with routine healing, classified as type IIIA, IIIB, or IIIC. Documentation should clearly indicate the fracture type, healing status, and that this is a follow-up visit. Ensure the open fracture classification and "routine healing" are explicitly documented to support accurate coding.
