Subluxation of proximal interphaln joint of r idx fngr, init

This code signifies a partial dislocation of the joint closest to the palm in the right index finger. The bones forming the joint are no longer perfectly aligned but remain in contact.

This code is appropriate for the initial visit where a patient presents with a subluxation of the proximal interphalangeal joint of the right index finger due to an acute injury. It should be used when the patient is receiving active treatment for the injury.

• Ensure documentation specifies the right index finger and the proximal interphalangeal joint.
• Confirm this is the initial encounter for this specific injury; subsequent encounters will require different seventh characters.
• Distinguish from a complete dislocation (luxation), which would be coded differently.
