Subluxation of carpometacarpal joint of right hand, sequela

This code signifies a chronic or residual subluxation affecting a carpometacarpal joint in the right hand, excluding the thumb. It indicates a persistent partial dislocation that occurred in the past and is now being treated or evaluated for its long-term effects. This condition often results in ongoing pain, instability, or functional limitations.

Use this code when documenting a patient presenting with a history of a right carpometacarpal joint subluxation (other than the thumb) where the acute injury has resolved, but the patient continues to experience symptoms or requires ongoing management related to the residual instability. This applies to follow-up visits for chronic pain, limited range of motion, or planned interventions for the sequela of the original subluxation.

• Always ensure documentation clearly specifies "sequela" or "chronic" to support the seventh character 'S'.
• Confirm the affected joint is a carpometacarpal joint and not another hand joint, and that it is on the right side.
• Do not use for acute subluxations; those require an initial encounter (A) or subsequent encounter (D) seventh character.
