Subluxation of unsp interphaln joint of r idx fngr, init

This code signifies a partial dislocation of an interphalangeal joint within the right index finger, where the specific joint (proximal or distal) is not documented. 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.

Apply this code when documentation clearly indicates a subluxation of an interphalangeal joint of the right index finger, but the physician does not specify whether it's the PIP or DIP joint. This is appropriate for the initial treatment of such an injury.

• Ensure the documentation specifies "subluxation" and not a complete "dislocation."
• Confirm the injury involves the right index finger and not another digit or hand.
• Verify this is the initial encounter for this specific injury; subsequent encounters will require different seventh characters.
