Subluxation of MCP joint of right middle finger, init

This code signifies a partial dislocation of the joint connecting the metacarpal bone to the first bone of the right middle finger. The joint surfaces are no longer perfectly aligned but still maintain some contact.

Apply this code when documenting the initial treatment or evaluation of a patient presenting with a subluxation of the metacarpophalangeal joint of their right middle finger. This typically follows an acute injury or trauma to the hand.

• Ensure laterality (right) and digit (middle finger) are accurately documented.
• Confirm this is the initial encounter for this specific injury; subsequent care would use a different seventh character.
• Distinguish from a complete dislocation (luxation), which would be coded differently.
