Subluxation of proximal interphaln joint of l idx fngr, init

This diagnosis code indicates a partial dislocation of the joint closest to the palm in the left index finger. It signifies that the joint surfaces are no longer perfectly aligned but are still in partial contact. This injury typically results in pain, swelling, and limited range of motion in the affected finger.

Use this code for a patient presenting with a newly diagnosed subluxation of the proximal interphalangeal (PIP) joint of the left index finger. This applies to the initial evaluation and treatment of the injury, such as when a patient first seeks medical attention after an acute trauma.

• Ensure documentation specifies "left index finger" and "proximal interphalangeal joint" to support this specific code.
• The "A" at the end indicates an initial encounter for this injury; subsequent care would require a different seventh character.
• Distinguish from a complete dislocation (luxation) which would be coded differently.
