Subluxation of unsp interphaln joint of l mid finger, init

This code signifies a partial dislocation of an interphalangeal joint within the left middle finger, where the joint surfaces have lost their normal alignment but remain in partial contact. It indicates the initial presentation or treatment for this specific injury.

This code is appropriate for documenting the first encounter for a patient presenting with a subluxation of an unspecified interphalangeal joint in their left middle finger. This could result from trauma, such as a fall or direct impact to the finger, leading to pain, swelling, and limited range of motion.

• Ensure documentation specifies "subluxation" rather than a full "dislocation" to differentiate from S63.123A.
• Verify the affected finger is the "middle finger" and the side is "left."
• Confirm this is the "initial encounter" for treatment of this specific injury.
