Subluxation of proximal interphaln joint of finger, subs

This code indicates a partial dislocation of the middle joint of a finger other than the thumb, occurring during a follow-up visit. The joint surfaces are no longer perfectly aligned, but the bones remain in contact. This injury typically results in pain, swelling, and limited range of motion in the affected finger.

Apply this code when a patient presents for ongoing treatment or evaluation of a previously diagnosed subluxation of the proximal interphalangeal (PIP) joint of any finger except the thumb. This includes follow-up appointments for physical therapy, re-evaluation after initial treatment, or management of persistent symptoms.

• Ensure the documentation clearly specifies a "subsequent encounter" for the injury.
• Verify the affected joint is the PIP joint and not the DIP or MCP joint.
• Confirm the injury involves a finger other than the thumb; otherwise, a different code is required.
