Subluxation of MCP joint of left middle finger, init

This code signifies a partial dislocation of the joint connecting the metacarpal bone to the first bone of the left middle finger. The joint surfaces are no longer perfectly aligned but remain in partial contact. This injury typically results in pain, swelling, and limited range of motion in the affected finger.

Apply this code when documenting an initial assessment and treatment for a patient presenting with a subluxation of the metacarpophalangeal joint of their left middle finger. This includes cases resulting from trauma, sports injuries, or other mechanisms causing a partial displacement of this specific joint.

• Ensure the documentation specifies "subluxation" rather than a full "dislocation" for this joint.
• Verify the laterality (left) and the specific digit (middle finger) are clearly stated in the medical record.
• The "A" seventh character indicates an initial encounter for active treatment of the injury.
