Subluxation of MCP joint of left index finger, sequela

This code signifies a chronic or residual condition resulting from a prior subluxation of the metacarpophalangeal (MCP) joint of the left index finger. It indicates that the patient is experiencing ongoing effects, such as pain, stiffness, or limited range of motion, directly attributable to the historical joint displacement.

Apply this code when documenting a patient presenting with long-term complications or persistent symptoms following a previously treated or resolved subluxation of the left index finger MCP joint. This is appropriate for follow-up visits addressing chronic pain, instability, or functional impairment related to the old injury.

• Always use this code as a secondary diagnosis, with a primary code describing the current manifestation (e.g., chronic pain).
• Ensure documentation clearly links the current symptoms to a past subluxation of the specified joint.
• The "S" seventh character indicates sequela, meaning the condition is a late effect of the original injury.
