Dislocation of metacarpophalangeal joint of finger, sequela

This code indicates a long-term complication or residual effect stemming from a prior dislocation of the metacarpophalangeal (MCP) joint in any finger other than the thumb. These sequelae can include chronic pain, stiffness, instability, or deformity that persists after the initial injury has healed.

Apply this code when documenting a patient presenting with a current condition directly attributable to an MCP joint dislocation of a non-thumb finger that occurred in the past. This is appropriate for follow-up encounters addressing the chronic consequences of such an injury, not the initial acute dislocation.

• Always assign an additional code to specify the nature of the sequela (e.g., M24.54- for contracture, M19.90 for unspecified arthritis).
• Ensure documentation clearly links the current condition to the historical MCP joint dislocation.
• Do not use this code for acute or subacute dislocations; those require codes from the initial encounter or subsequent encounter categories.
