S92.045K Nondisplaced other fracture of tuberosity of left calcaneus, subsequent encounter for fracture with nonunion

Name of the Condition

• Nondisplaced other fracture of tuberosity of left calcaneus, subsequent encounter for fracture with nonunion

Summary

This condition refers to a nondisplaced fracture of the tuberosity of the left calcaneus (heel bone) that has not healed properly, resulting in nonunion. The tuberosity is a bony prominence where the Achilles tendon attaches, and the fracture is classified as "other" to denote a specific type of injury. The "subsequent encounter" indicates this is a follow-up visit for the fracture, and "nonunion" means the bone fragments have failed to fuse after an expected healing period. This may require additional intervention to promote healing.

Causes

The fracture typically results from high-impact trauma, such as falls or direct blows to the heel, or repetitive stress during activities like jumping or running. Nonunion may occur due to inadequate immobilization, poor blood supply to the fracture site, or underlying health conditions that impair healing.

Risk Factors

• Participation in high-impact sports (e.g., running, basketball)
• Osteoporosis or weakened bone density
• Poor footwear or inadequate foot support
• Occupational hazards involving heavy lifting or falls
• Smoking or other factors that impair bone healing

Symptoms

• Persistent localized heel pain, especially with weight-bearing
• Swelling or bruising around the heel
• Tenderness at the tuberosity site
• Difficulty walking or standing
• Possible instability or weakness in the affected foot

Diagnosis

Physical examination to assess pain, swelling, and range of motion. Imaging tests, such as X-rays or CT scans, to confirm nonunion by evaluating the fracture site for persistent gaps or lack of bone healing. Additional tests may be ordered to rule out infection or other complications.

Treatment Options

• Immobilization with a cast or brace to stabilize the fracture
• Surgical intervention, such as bone grafting or internal fixation, to promote healing
• Pain management with medications or physical therapy
• Weight-bearing restrictions to reduce stress on the fracture site

Prognosis and Follow-Up

Prognosis depends on the severity of nonunion and response to treatment. Follow-up imaging and clinical assessments are necessary to monitor healing progress. Long-term management may include physical therapy to restore function and prevent future injuries.

Complications

• Chronic pain or instability
• Infection at the fracture site
• Delayed or failed healing requiring additional surgery
• Long-term mobility issues or gait abnormalities

Lifestyle & Prevention

• Wear supportive footwear to reduce stress on the heel
• Avoid high-impact activities until cleared by a healthcare provider
• Maintain bone health through diet and exercise
• Use proper techniques during sports or physical activities to minimize injury risk

When to Seek Professional Help

Seek medical attention if you experience persistent heel pain, swelling, or difficulty walking after a fracture. Prompt evaluation is important if symptoms worsen or new complications arise, such as increased pain, redness, or signs of infection.

Tips for Medical Coders

Document the fracture type (nondisplaced, other), location (left calcaneus tuberosity), and encounter type (subsequent) clearly. Specify "nonunion" to indicate the fracture has not healed, and ensure documentation supports the need for follow-up care. Include details about imaging results or clinical findings that confirm nonunion to justify the code assignment.
