Subluxation of MCP joint of right ring finger, sequela

This code describes a long-term or late effect of a previous subluxation (partial dislocation) of the metacarpophalangeal (MCP) joint of the right ring finger. This indicates that the initial injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to that past subluxation.

Use this code when documenting a patient presenting with ongoing issues, such as chronic pain, instability, limited range of motion, or deformity, in the right ring finger's MCP joint, and these issues are directly linked to a previously treated subluxation. This code is appropriate for follow-up encounters addressing these persistent sequelae, not for the initial acute injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, instability).
• Ensure documentation clearly links the current condition to a past subluxation of the right ring finger MCP joint.
• Verify the laterality (right) and specific joint (ring finger MCP) are accurately documented to support this code.
