Subluxation of MCP joint of right little finger, init

This code signifies a partial dislocation of the joint connecting the metacarpal bone to the first phalanx of the right little finger. This injury involves stretching or tearing of the joint capsule and ligaments, but the joint surfaces remain in partial contact. Patients typically present with pain, swelling, and limited range of motion in the affected finger.

Apply this code when documenting an initial encounter for a patient diagnosed with a subluxation of the right little finger's metacarpophalangeal joint. This is appropriate for acute injuries resulting from trauma or sudden forceful movements. It should be used when the patient is first seen for this specific injury.

• Ensure documentation clearly specifies "subluxation" rather than a complete dislocation.
• Verify the affected digit is the "little finger" and the side is "right."
• Confirm this is the "initial encounter" for treatment of this specific injury.
