S82.454N Nondisplaced comminuted fracture of shaft of right fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion

Name of the Condition

• Nondisplaced comminuted fracture of shaft of right fibula, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with nonunion
• ICD-10 Code: S82.454N

Summary

A nondisplaced comminuted fracture of the shaft of the right fibula is a break in the long, slender bone of the lower leg where the bone is shattered into multiple pieces but the fragments remain in their original alignment. This fracture is classified as an open fracture type IIIA, IIIB, or IIIC, indicating significant soft tissue damage, and is associated with nonunion, meaning the bone has failed to heal properly. The "subsequent encounter" designation indicates this is a follow-up visit for ongoing treatment of the fracture.

Causes

This fracture typically results from direct trauma or high-impact force to the leg, such as falls, motor vehicle accidents, or sports injuries. The comminution (shattering into multiple pieces) occurs due to significant force, while the nondisplaced nature suggests the fragments did not shift out of position. Open fracture types IIIA, IIIB, or IIIC indicate severe soft tissue damage, and nonunion may develop due to inadequate healing, infection, or poor blood supply to the fracture site.

Risk Factors

• Participation in high-impact or contact sports
• Osteoporosis or conditions that weaken bone density
• Advanced age, which may reduce bone strength
• Previous leg injuries or surgeries
• Poor blood supply to the fracture site
• Infection at the fracture site

Symptoms

• Persistent pain and tenderness along the right fibula
• Swelling and bruising around the lower leg
• Difficulty bearing weight on the affected leg
• Possible deformity or instability of the leg structure
• Signs of nonunion, such as lack of healing on imaging
• Open wound or soft tissue damage (if applicable)

Diagnosis

Diagnosis involves a physical examination to assess tenderness, swelling, and deformity. Imaging tests, such as X-rays or CT scans, are typically used to confirm the fracture, determine the number of bone fragments, and assess for nonunion. Additional tests, such as MRI or bone scans, may be performed to evaluate soft tissue damage and blood supply to the fracture site.

Treatment Options

Treatment may include surgical intervention to stabilize the fracture, such as internal fixation with plates or screws, or bone grafting to promote healing. Non-surgical options, such as casting or bracing, may be used in some cases. Antibiotics may be prescribed if infection is present, and physical therapy may be recommended to restore function and strength.

Prognosis and Follow-Up

Prognosis depends on the severity of the fracture, the presence of nonunion, and the effectiveness of treatment. Follow-up care is essential to monitor healing and address any complications. Regular imaging and physical examinations may be required to assess progress and adjust treatment as needed.

Complications

• Nonunion or delayed healing
• Infection at the fracture site
• Nerve or blood vessel damage
• Chronic pain or instability
• Limited mobility or function

Lifestyle & Prevention

• Avoid high-impact activities that may increase the risk of injury
• Maintain bone health through proper nutrition and exercise
• Use protective equipment during sports or activities
• Follow post-injury care instructions to promote healing

When to Seek Professional Help

Seek medical attention if you experience persistent pain, swelling, or difficulty bearing weight, or if you notice signs of infection, such as redness, warmth, or drainage from the wound.

Tips for Medical Coders

When coding for S82.454N, ensure documentation supports the presence of a nondisplaced comminuted fracture of the right fibula shaft, an open fracture type IIIA, IIIB, or IIIC, and nonunion. The "subsequent encounter" designation indicates ongoing treatment for the fracture, and coders should verify that the encounter is not the initial or acute phase of care. Accurate documentation of the fracture type, location, and healing status is essential for correct coding.
