Subluxation of MCP joint of right index finger, sequela

This code signifies a chronic or late-effect condition involving the partial dislocation (subluxation) of the joint connecting the metacarpal bone to the first phalanx of the right index finger. It indicates that the current subluxation is a residual effect of a previous injury or condition, rather than an acute event.

This code is appropriate for documenting a patient presenting with ongoing symptoms or findings related to a previously sustained subluxation of the right index finger's metacarpophalangeal joint. This includes cases where the initial injury has healed, but the joint remains partially displaced or exhibits long-term instability.

• Always use this code as a secondary diagnosis, following the code for the primary reason for the encounter.
• Ensure documentation clearly states the subluxation is a "sequela" or "late effect" of a prior injury.
• Do not use for acute or initial subluxations; those require codes from the acute injury section.
