S92.224K Nondisplaced fracture of lateral cuneiform of right foot, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced fracture of lateral cuneiform of right foot, subsequent encounter for fracture with nonunion

Summary

A nondisplaced fracture of the lateral cuneiform of the right foot involves a break in the lateral cuneiform bone, one of the tarsal bones in the midfoot, where the bone fragments remain aligned. This condition is documented as a subsequent encounter, indicating ongoing care after the initial treatment phase, and is associated with nonunion, meaning the fracture has failed to heal properly. The severity depends on the extent of the nonunion and any associated complications.

Causes

Typically caused by direct trauma, such as falls, sports injuries, or motor vehicle accidents. Nonunion may develop due to inadequate immobilization, poor blood supply to the bone, infection, or excessive movement at the fracture site during healing.

Risk Factors

• Participation in high-impact sports or activities.
• Osteoporosis or other bone-weakening conditions.
• Older age due to decreased bone density.
• Previous foot injuries or fractures.
• Improper footwear or inadequate protective gear.
• Smoking or other factors that impair bone healing.

Symptoms

• Persistent pain at the fracture site, often worsening with weight-bearing.
• Swelling and tenderness in the midfoot that does not improve over time.
• Difficulty walking or inability to bear weight on the affected foot.
• Possible deformity or instability of the midfoot.
• Lack of healing progress noted on follow-up imaging.

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays, CT scans, or MRIs, to evaluate the fracture site for signs of nonunion, including a persistent fracture line, lack of callus formation, or bone gap. Additional tests may be ordered to assess blood flow or rule out infection.

Treatment Options

Treatment focuses on promoting healing and may include immobilization with a cast or brace, bone stimulation therapies, or surgical intervention such as bone grafting or internal fixation. Pain management and physical therapy are often part of the care plan to restore function.

Prognosis and Follow-Up

Prognosis depends on the success of treatment and the underlying cause of nonunion. Regular follow-up with imaging is necessary to monitor healing progress. Long-term outcomes may vary, with some patients experiencing persistent pain or functional limitations.

Complications

• Chronic pain or arthritis in the midfoot.
• Persistent instability or deformity.
• Infection, particularly if surgical intervention is required.
• Delayed return to normal activities or sports.

Lifestyle & Prevention

• Avoid high-impact activities until cleared by a healthcare provider.
• Use proper footwear and protective gear during activities.
• Maintain bone health through adequate nutrition and exercise.
• Follow post-treatment instructions carefully to support healing.

When to Seek Professional Help

Seek medical attention if pain worsens, swelling increases, or new symptoms such as fever or redness develop. Persistent difficulty walking or lack of improvement after treatment warrants further evaluation.

Tips for Medical Coders

Document the subsequent encounter and nonunion clearly in the medical record. Ensure the fracture is confirmed as nondisplaced and specify the lateral cuneiform of the right foot. Include details about treatment provided and any imaging results to support the diagnosis.
