Subluxation of MCP joint of right thumb, sequela

This code signifies a chronic or late-effect condition involving a partial dislocation of the joint connecting the thumb's metacarpal bone to its first phalanx on the right hand. The joint surfaces are no longer perfectly aligned, but they remain in partial contact. This sequela may result in persistent pain, instability, or functional limitations long after the initial injury.

Use this code when documenting a patient presenting with ongoing symptoms or complications directly attributable to a previously sustained subluxation of the right thumb's metacarpophalangeal joint. This is appropriate for follow-up encounters where the initial injury has healed, but residual effects are being managed. It should be applied when the condition is no longer acute but represents a lasting consequence.

• Always use an additional code to identify the specific sequela, such as pain or functional impairment, if applicable.
• Ensure documentation clearly indicates the right thumb and the metacarpophalangeal joint as the affected site.
• This "S" seventh character indicates a sequela, meaning it's used for complications or conditions arising as a direct result of a previous injury, not for the initial acute injury itself.
