Sublux of MC (bone), proximal end of right hand, init

This code signifies a partial dislocation of the metacarpal bone at its proximal end, specifically in the right hand. This means the joint surfaces are no longer perfectly aligned but still maintain some contact, often resulting from trauma or injury.

Apply this code when documentation confirms a subluxation of the right metacarpal's proximal end, such as from a fall, direct impact, or sports injury. It is appropriate for the initial treatment of the injury, including diagnosis and active treatment.

• Ensure the documentation specifies "subluxation" rather than a complete dislocation.
• Verify the affected hand is the right hand and the injury is to the proximal end of the metacarpal.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
