Subluxation of MCP joint of left ring finger, sequela

This code indicates a partial dislocation or misalignment of the joint connecting the left ring finger to the hand, specifically as a long-term effect or complication of an earlier injury. The joint surfaces are no longer in proper apposition but remain in partial contact.

Use this code when documenting a chronic or residual subluxation of the left ring finger's metacarpophalangeal joint, meaning the initial injury has healed but this partial dislocation persists as a lasting consequence. This would apply to follow-up encounters for ongoing management or evaluation of the chronic condition.

• Requires a seventh character "S" to denote sequela, indicating a complication or residual effect of a previous injury.
• Ensure documentation clearly links the current subluxation to an earlier traumatic event.
• Do not use for acute or initial subluxations; those would require an "A" or "D" seventh character.
