Subluxation of MCP joint of left ring finger, init

This code signifies a partial dislocation of the joint connecting the metacarpal bone to the first phalanx of the left ring finger. The joint surfaces are no longer in complete apposition, but some contact remains. This injury typically involves damage to the supporting ligaments and joint capsule.

This code is appropriate for the initial treatment of a patient presenting with a subluxation of the left ring finger's metacarpophalangeal joint. This includes the initial evaluation, diagnosis, and any immediate treatment provided, such as reduction or splinting. It should be used when the injury is acute and the patient is receiving their first medical attention for this specific condition.

• Ensure documentation clearly specifies "left ring finger" and "metacarpophalangeal joint."
• Verify the encounter is indeed the "initial encounter" for this specific injury. Subsequent care would require a different seventh character.
• Distinguish subluxation from a complete dislocation (luxation), which would be coded differently.
