Sublux of MC (bone), proximal end of right hand, sequela

This code signifies a partial dislocation of the metacarpal bone at its proximal end, specifically in the right hand, where the joint surfaces are no longer in full apposition but remain in partial contact. It is used to report the residual effects or complications arising from an initial injury, rather than the acute injury itself.

This code is appropriate for documenting long-term problems or conditions that are a direct result of a previous subluxation of the proximal right metacarpal. Examples include chronic pain, stiffness, limited range of motion, or deformity persisting after the initial injury has healed. It should be used when the patient is presenting for treatment of these lasting effects.

• Always assign a "S" (sequela) seventh character when the patient is being treated for the late effects of the injury.
• Do not use this code for acute or initial subluxations; those require an "A" (initial encounter) or "D" (subsequent encounter) seventh character.
• Ensure documentation clearly links the current condition to a previous right proximal metacarpal subluxation.
