Subluxation of MCP joint of right middle finger, sequela

This code indicates a persistent or late-effect condition of a partial dislocation of the joint connecting the metacarpal bone to the first bone of the right middle finger. This subluxation implies that the joint surfaces are still in partial contact, but their alignment is abnormal, leading to ongoing symptoms or functional impairment.

Use this code when documenting the long-term consequences or residual effects of a previous subluxation of the right middle finger's metacarpophalangeal joint. This applies to situations where the initial injury has healed, but the patient continues to experience issues directly attributable to the past subluxation, such as chronic pain, stiffness, or instability.

• Requires a seventh character "S" to indicate sequela, meaning the condition is a late effect of a previous injury.
• Do not use for acute or initial subluxations; those require different seventh characters.
• Ensure documentation clearly links the current symptoms to a prior subluxation of the specified joint and finger.
