S92.201K Fracture of unspecified tarsal bone(s) of right foot, subsequent encounter for fracture with nonunion

Name of the Condition

• Fracture of unspecified tarsal bone(s) of right foot, subsequent encounter for fracture with nonunion

Summary

A fracture of unspecified tarsal bone(s) of the right foot, subsequent encounter for fracture with nonunion, refers to a break in one or more bones of the tarsus (rearfoot/midfoot) on the right side where healing has not progressed as expected. This is a follow-up visit for a fracture that has failed to unite, requiring ongoing management. The term "unspecified" indicates the exact tarsal bone involved is not documented.

Causes

Typically caused by initial trauma such as falls, sports injuries, or direct impacts to the foot. Nonunion may result from 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 bone-weakening conditions.
• Smoking, which impairs bone healing.
• Poor nutrition or vitamin deficiencies affecting bone health.
• Previous foot injuries or fractures.

Symptoms

• Persistent pain at the fracture site, often worsening with weight-bearing.
• Swelling or tenderness that does not improve over time.
• Limited range of motion in the right foot.
• Possible deformity or instability of the foot.

Diagnosis

Physical examination to assess pain, swelling, and movement limitations. Imaging tests such as X-rays, CT scans, or MRIs to evaluate bone healing and confirm nonunion. Comparison with prior imaging may be used to assess progress.

Treatment Options

• Surgical intervention, such as bone grafting or internal fixation, to promote healing.
• Extended immobilization with casts or braces to stabilize the fracture.
• Physical therapy to restore function and strength.
• Pain management medications as needed.

Prognosis and Follow-Up

Prognosis depends on the severity of the nonunion and response to treatment. Regular follow-up visits and imaging are typically required to monitor healing. Some cases may require long-term management to address functional limitations.

Complications

• Chronic pain or discomfort.
• Arthritis or joint damage due to improper healing.
• Reduced mobility or difficulty walking.
• Increased risk of future fractures in the affected area.

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.
• Use proper footwear and protective gear during activities.
• Follow post-treatment instructions carefully to optimize healing.

When to Seek Professional Help

Seek immediate medical attention if you experience severe pain, swelling, or deformity, or if you notice signs of infection such as redness, warmth, or drainage at the fracture site.

Tips for Medical Coders

Document the encounter as a subsequent visit for fracture with nonunion. Ensure clinical notes specify the fracture location (right foot, unspecified tarsal bone) and confirm the nonunion status. Include details on treatment provided and any imaging results to support the diagnosis.
