Subluxation of MCP joint of right little finger, sequela

This diagnosis indicates a partial dislocation of the joint connecting the metacarpal bone to the first phalanx of the right little finger, where the joint surfaces are still in partial contact. The "sequela" designation signifies that this subluxation is a residual effect or complication of an earlier injury or condition, rather than an acute event.

This code is appropriate for documenting chronic or long-standing instability or malalignment of the right little finger's metacarpophalangeal joint. It should be used when the patient presents for treatment of ongoing symptoms directly related to a previously sustained subluxation, such as persistent pain, stiffness, or functional impairment.

• Ensure documentation clearly states the subluxation is of the right little finger's metacarpophalangeal joint and is a sequela.
• Do not use this code for acute or initial encounters for a subluxation; specific acute codes exist for those scenarios.
• Always review the patient's history to confirm the chronic nature or residual effect of the subluxation.
