Sublux of proximal interphaln joint of l mid finger, sequela

This code indicates a long-term or late effect of a previous subluxation (partial dislocation) of the joint closest to the palm on the left middle finger. This means the initial injury has healed, but there are ongoing symptoms or conditions directly resulting from that past event.

Apply this code when documenting a patient presenting with residual pain, stiffness, deformity, or functional limitation in the left middle finger's proximal interphalangeal joint, and the medical record clearly links these issues to a prior subluxation. This is appropriate for follow-up visits addressing chronic problems stemming from the original injury.

• Always sequence this 'S' code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic pain, osteoarthritis).
• Ensure documentation explicitly states the current condition is a "sequela," "late effect," or "due to old injury" of a previous subluxation.
• Verify the affected joint is the proximal interphalangeal joint and the correct finger (middle) and side (left) are documented.
