S93.141S Subluxation of metatarsophalangeal joint of right great toe, sequela

Name of the Condition

• Subluxation of metatarsophalangeal joint of right great toe, sequela

Summary

Subluxation of the metatarsophalangeal joint of the right great toe, sequela, refers to the residual effects of a partial joint displacement that occurred in the past. This condition involves persistent joint instability, pain, or functional impairment resulting from the original injury. Sequela indicates the condition is a late effect, not an acute event, and may require ongoing management to address chronic symptoms or structural changes.

Causes

The sequela arises from a prior subluxation of the metatarsophalangeal joint of the right great toe, typically caused by trauma such as direct impact, twisting, or forceful bending. The original injury may have resulted from accidents, sports activities, or stubbing the toe, leading to incomplete joint displacement that did not fully resolve or healed with residual dysfunction.

Risk Factors

• History of trauma to the right great toe or metatarsophalangeal joint
• Inadequate initial treatment or incomplete healing of the original subluxation
• Underlying joint instability or connective tissue weakness
• Repetitive stress on the joint from weight-bearing activities

Symptoms

• Chronic pain or discomfort at the metatarsophalangeal joint
• Swelling or stiffness that persists beyond the acute injury phase
• Reduced range of motion in the big toe
• Difficulty with weight-bearing or gait abnormalities
• Visible or palpable joint instability

Diagnosis

Clinical evaluation focuses on the history of the original injury and current symptoms. Physical examination assesses joint stability, pain, and functional limitations. Imaging, such as X-rays, may be used to evaluate residual joint alignment or degenerative changes. Documentation of the sequela must link the current condition to the prior subluxation.

Treatment Options

• Supportive care: Orthotics, bracing, or modified footwear to stabilize the joint
• Physical therapy: Exercises to improve strength, flexibility, and function
• Pain management: NSAIDs or other modalities to address chronic discomfort
• Surgical evaluation: Considered for severe instability or functional impairment

Prognosis and Follow-Up

Prognosis depends on the severity of residual joint damage and adherence to treatment. Chronic symptoms may persist, but most patients experience improved function with conservative management. Regular follow-up ensures symptoms are monitored, and treatment is adjusted as needed.

Complications

• Chronic pain or arthritis in the metatarsophalangeal joint
• Progressive joint instability or deformity
• Reduced mobility or gait abnormalities
• Need for surgical intervention in refractory cases

Lifestyle & Prevention

• Wear supportive footwear to reduce joint stress
• Avoid high-impact activities that strain the toe
• Maintain a healthy weight to minimize joint load
• Perform toe-strengthening exercises to enhance stability

When to Seek Professional Help

Seek care if chronic pain worsens, swelling recurs, or mobility declines. Prompt evaluation is necessary if new deformity or instability develops, as these may indicate progression of the sequela or a new injury.

Tips for Medical Coders

Use S93.141S for sequela of subluxation of the metatarsophalangeal joint of the right great toe. Document the relationship between the current condition and the prior subluxation, including the time elapsed since the original injury. Ensure specificity regarding the right great toe and the sequela status to align with coding guidelines.
