Dislocation of carpometacarpal joint of left hand, sequela

This code signifies a long-term complication or late effect resulting from a previous dislocation of any carpometacarpal joint in the left hand, excluding the thumb. This could include persistent pain, instability, limited range of motion, or degenerative changes that manifest after the initial injury has healed.

Apply this code when documenting a patient presenting with ongoing issues directly attributable to a past dislocation of a carpometacarpal joint (excluding the thumb) in their left hand. This is appropriate for follow-up visits where the primary focus is managing these residual effects, rather than the acute injury itself.

• Always use this code as a secondary diagnosis, following a code for the specific sequela (e.g., chronic pain, osteoarthritis).
• Ensure documentation clearly links the current condition to a previous left carpometacarpal dislocation.
• The "S" seventh character indicates sequela and is crucial for proper code assignment.
