S92.043K Displaced other fracture of tuberosity of unspecified calcaneus, subsequent encounter for fracture with nonunion

Name of the Condition

• Displaced other fracture of tuberosity of unspecified calcaneus, subsequent encounter for fracture with nonunion

Summary

This condition involves a displaced fracture of the tuberosity of the calcaneus (heel bone) during a subsequent encounter, where healing has failed to progress (nonunion). The fracture is classified as "other" to denote a specific type of tuberosity injury, and displacement indicates the bone fragments are not aligned. Nonunion means the fracture site has not healed within the expected timeframe, requiring further evaluation and intervention.

Causes

High-impact trauma to the heel, such as falls from a height, direct blows, or sports-related injuries, can cause this fracture. Repetitive stress or sudden force applied to the heel may also lead to tuberosity displacement. Nonunion may result from inadequate immobilization, poor blood supply, infection, or underlying health conditions affecting bone healing.

Risk Factors

• Participation in high-impact activities (e.g., running, jumping)
• Osteoporosis or reduced bone density
• Poor footwear or inadequate foot support
• Occupational hazards involving falls or heavy lifting
• Smoking or other factors impairing bone healing

Symptoms

• Persistent heel pain, especially with weight-bearing
• Swelling or bruising that does not resolve
• Difficulty walking or standing
• Possible visible deformity or abnormal positioning of the heel

Diagnosis

Physical examination assesses pain, swelling, and range of motion. Imaging, typically X-rays, confirms the fracture and evaluates nonunion. CT scans may be used for detailed assessment of the fracture site and bone healing. Additional tests may check for underlying conditions affecting healing.

Treatment Options

• Surgical intervention to stabilize the fracture (e.g., internal fixation)
• Bone grafting to promote healing
• Immobilization with a cast or brace
• Pain management with medications
• Physical therapy to restore function

Prognosis and Follow-Up

Prognosis depends on the success of treatment and addressing underlying causes of nonunion. Follow-up imaging monitors healing progress. Long-term outcomes may include persistent pain or functional limitations if healing is incomplete. Regular medical evaluation is necessary to adjust treatment plans.

Complications

• Chronic pain or instability
• Infection at the fracture site
• Reduced mobility or gait abnormalities
• Need for additional surgeries
• Long-term disability

Lifestyle & Prevention

• Wear supportive footwear to reduce injury risk
• Avoid high-impact activities if bone density is low
• Maintain a healthy diet rich in calcium and vitamin D
• Quit smoking to improve bone healing
• Use protective gear during sports or high-risk activities

When to Seek Professional Help

Seek medical care if heel pain persists, worsens, or interferes with daily activities. Immediate attention is needed for severe pain, swelling, or signs of infection (e.g., redness, fever). Follow up with a healthcare provider if symptoms do not improve with initial treatment.

Tips for Medical Coders

Document the encounter as subsequent for fracture with nonunion. Ensure clinical notes specify nonunion and any contributing factors (e.g., poor healing, infection). Code S92.043K is used when the fracture is displaced, involves the tuberosity of the calcaneus, and is a subsequent encounter with nonunion. Verify documentation supports the diagnosis and encounter type.
