S92.042S Displaced other fracture of tuberosity of left calcaneus, sequela

Name of the Condition

• Displaced other fracture of tuberosity of left calcaneus, sequela

Summary

This condition represents a displaced fracture of the tuberosity of the left calcaneus (heel bone) during the sequela phase. The tuberosity is a bony prominence where the Achilles tendon attaches, and displacement indicates the bone fragments are not aligned. The sequela designation indicates this is a residual effect or complication following the initial injury, rather than an active fracture.

Causes

The sequela phase follows an initial displaced fracture of the calcaneal tuberosity, typically resulting from high-impact trauma such as falls, direct blows, or sports-related injuries. The current condition reflects the long-term effects of the original fracture, which may include malunion, nonunion, or persistent displacement.

Risk Factors

• Prior history of calcaneal tuberosity fracture
• Inadequate initial fracture management
• Delayed or incomplete healing
• Underlying bone conditions affecting healing (e.g., osteoporosis)
• High-impact activities resuming before full recovery

Symptoms

• Chronic heel pain, especially with weight-bearing
• Persistent swelling or deformity
• Reduced range of motion in the ankle or foot
• Difficulty walking or standing for extended periods
• Possible instability or weakness in the affected foot

Diagnosis

Physical examination evaluates residual pain, deformity, and functional limitations. Imaging, typically X-rays, assesses bone alignment and healing status. CT scans may be used to evaluate complex malunions. Documentation must specify the sequela phase and any associated complications.

Treatment Options

• Orthotic devices or supportive footwear to improve stability
• Physical therapy to restore strength and mobility
• Pain management strategies for chronic discomfort
• Surgical intervention for severe malunion or functional impairment
• Activity modification to avoid exacerbating symptoms

Prognosis and Follow-Up

Prognosis depends on the severity of the initial injury and residual displacement. Chronic pain or functional limitations may persist. Regular follow-up with imaging and clinical assessment helps monitor healing and adjust management. Long-term monitoring for arthritis or other complications is often necessary.

Complications

• Chronic pain or discomfort
• Persistent deformity or instability
• Post-traumatic arthritis in the subtalar joint
• Reduced mobility or gait abnormalities
• Potential need for additional surgical intervention

Lifestyle & Prevention

• Use appropriate footwear with good arch support
• Avoid high-impact activities that stress the heel
• Maintain bone health through diet and exercise
• Follow rehabilitation protocols after initial injury
• Seek prompt evaluation for new or worsening symptoms

When to Seek Professional Help

Consult a healthcare provider if experiencing increasing pain, new swelling, difficulty bearing weight, or signs of infection. Early evaluation is important for managing residual effects and preventing further complications.

Tips for Medical Coders

Document the sequela phase clearly, including the nature of the residual effects (e.g., malunion, nonunion) and any associated functional limitations. Ensure the code S92.042S is used only when the condition represents a late effect of the initial fracture, not an active injury. Include details about prior treatment and current symptoms to support the sequela designation.
