S93.142 Subluxation of metatarsophalangeal joint of left great toe

Name of the Condition

• Subluxation of metatarsophalangeal joint of left great toe

Summary

Subluxation of the metatarsophalangeal joint of the left great toe involves partial displacement of the joint where the big toe meets the foot, leading to pain, swelling, and impaired movement. This condition typically results from trauma or mechanical stress and may affect the joint's stability and function.

Causes

Trauma such as direct impact, twisting, or stubbing the toe. Sudden forceful movements that exceed the joint's normal range of motion. Repetitive stress from activities like running or jumping.

Risk Factors

• Participation in high-impact activities (e.g., running, jumping, or contact sports)
• Previous foot or toe injuries
• Wearing improper footwear that lacks support or protection
• Underlying conditions affecting joint stability (e.g., hypermobility)

Symptoms

• Pain at the affected metatarsophalangeal joint
• Swelling or bruising around the joint
• Visible deformity or misalignment of the toe
• Difficulty walking or bearing weight on the foot
• Limited range of motion in the toe

Diagnosis

Physical examination to assess pain, swelling, and joint alignment. Imaging tests, such as X-rays, to confirm subluxation and rule out fractures. Clinical evaluation of movement and stability.

Treatment Options

• Reduction: Manual realignment of the joint by a healthcare professional.
• Immobilization: Use of splints, buddy taping, or protective footwear to stabilize the joint.
• Pain management: Nonsteroidal anti-inflammatory drugs (NSAIDs) or other analgesics to reduce discomfort.
• Rehabilitation: Physical therapy to restore strength, flexibility, and function.

Prognosis and Follow-Up

Most cases resolve with appropriate treatment, though recovery time depends on severity and adherence to care plans. Follow-up appointments may be needed to monitor healing and adjust treatment. Long-term outcomes are generally favorable with proper management.

Complications

• Chronic pain or instability if untreated
• Recurrent subluxation
• Arthritis or joint degeneration over time
• Difficulty with weight-bearing or gait

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities.
• Avoid sudden, forceful toe movements or impacts.
• Strengthen foot and toe muscles through targeted exercises.
• Use protective gear during high-risk sports or activities.

When to Seek Professional Help

Seek care if pain is severe, swelling worsens, or movement is significantly impaired. Immediate attention is needed if the toe appears deformed or if there is inability to bear weight.

Tips for Medical Coders

Document the specific location (left great toe) and confirm the diagnosis of subluxation. Ensure clinical notes support the partial displacement and exclude fractures or complete dislocations. Code S93.142 is specific to the left great toe; verify laterality and joint involvement for accurate assignment.
