S93.141D Subluxation of metatarsophalangeal joint of right great toe, subsequent encounter

Name of the Condition

• Subluxation of metatarsophalangeal joint of right great toe, subsequent encounter

Summary

Subluxation of the metatarsophalangeal joint of the right great toe involves partial displacement of the joint where the first metatarsal meets the proximal phalanx of the big toe. This condition typically causes pain, swelling, and impaired movement, often resulting from trauma or mechanical stress. The metatarsophalangeal joint is critical for weight-bearing and movement, so subluxation can affect gait and function. The "subsequent encounter" designation indicates this is a follow-up visit for the same injury.

Causes

Trauma such as direct impact, twisting, or forceful bending of the toe. Sudden movements that exceed the joint's normal range of motion. Accidents, sports injuries, or stubbing the toe against a hard surface.

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. Documentation must specify the right great toe and indicate this is a subsequent encounter for the injury.

Treatment Options

• Reduction: Manual realignment of the joint by a healthcare professional if needed.
• Immobilization: Use of splints, buddy taping, or protective footwear to stabilize the toe.
• Pain Management: Medications or therapies to reduce discomfort and inflammation.
• Rehabilitation: Exercises to restore strength and range of motion.

Prognosis and Follow-Up

Most cases resolve with proper treatment, though recovery time varies. Follow-up care ensures proper healing and prevents recurrence. Complications are rare with appropriate management, but ongoing monitoring may be necessary for severe or persistent cases.

Complications

• Chronic pain or instability in the joint
• Recurrent subluxation
• Development of arthritis in the affected joint
• Difficulty with weight-bearing or gait

Lifestyle & Prevention

• Wear supportive, properly fitting footwear during activities.
• Avoid sudden, forceful movements that stress the toe joint.
• Use protective gear (e.g., toe guards) during high-risk sports.
• Maintain foot strength and flexibility through regular exercise.

When to Seek Professional Help

Seek care if pain worsens, swelling persists, or movement is severely limited. Immediate attention is needed if the toe appears deformed or if there is inability to bear weight.

Tips for Medical Coders

Document the specific toe (right great toe) and encounter type (subsequent) clearly. Ensure clinical notes support the diagnosis and follow-up context. Verify that the injury is not a new or initial encounter to apply this code correctly.
