Subluxation of MCP joint of left middle finger, sequela

This code signifies a partial dislocation of the joint connecting the metacarpal bone to the first phalanx of the left middle finger, specifically indicating a residual effect or complication from an initial injury. The joint surfaces are no longer perfectly aligned, but remain in partial contact, leading to ongoing symptoms or functional limitations.

Apply this code when documenting a patient presenting with a long-term consequence or late effect of a previously sustained subluxation of the left middle finger's metacarpophalangeal joint. This is appropriate for follow-up encounters where the initial injury has healed, but the subluxation's lasting impact is being addressed.

• Always assign a "S" (sequela) seventh character for conditions that are residual effects of a previous injury.
• Ensure documentation clearly states the laterality (left) and specific digit (middle finger).
• Do not use for acute subluxations; those require an initial or subsequent encounter seventh character.
