Subluxation of metacarpophalangeal joint of finger, sequela

This code signifies a chronic or residual partial dislocation (subluxation) of a metacarpophalangeal (MCP) joint in any finger other than the thumb. It indicates that the injury is not acute but rather a long-term consequence of a previous trauma or condition affecting the joint's stability.

Apply this code when documenting a patient presenting with ongoing symptoms such as pain, instability, or limited range of motion in an MCP joint (excluding the thumb) due to a previously sustained subluxation. This is appropriate for follow-up visits after initial injury management or when the subluxation is identified as a pre-existing condition contributing to current symptoms.

• Ensure documentation clearly specifies "other finger" and not the thumb, as separate codes exist for thumb involvement.
• Verify that the subluxation is explicitly documented as a "sequela" or chronic condition, not an acute injury.
• Always code the underlying cause of the subluxation (e.g., trauma, inflammatory arthritis) if known and still relevant to the patient's care.
