Subluxation of distal interphaln joint of r idx fngr, init

This code signifies a partial dislocation of the most distant joint (DIP joint) of the right index finger. In a subluxation, the joint surfaces are no longer perfectly aligned but still maintain some contact, unlike a complete dislocation. This injury typically results in pain, swelling, and limited range of motion in the affected finger.

This code is appropriate for documenting the initial presentation and treatment of a patient who has sustained a subluxation of the right index finger's DIP joint. This includes emergency department visits, initial orthopedic consultations, or primary care evaluations following the injury.

• Ensure documentation specifies "right index finger" and "distal interphalangeal joint" to support this specific code.
• Verify the encounter is truly the "initial encounter" for this injury; subsequent care would use a different seventh character.
• Distinguish between subluxation (partial dislocation) and complete dislocation, as they have different codes.
