Subluxation of carpometacarpal joint of left hand, sequela

This code signifies a partial dislocation of a carpometacarpal joint in the left hand, excluding the thumb, where the joint surfaces are no longer perfectly aligned but remain in contact. This specific code is used to indicate that the subluxation is a long-term consequence or complication of a previous injury or condition, rather than an acute event.

Apply this code when documenting a patient presenting with ongoing symptoms or functional limitations in the left hand due to a past subluxation of a carpometacarpal joint (excluding the thumb). This is appropriate when the initial injury has healed, but residual effects of the subluxation persist. It should be used for follow-up encounters addressing these chronic issues.

• Always assign a seventh character "S" for sequela when the subluxation is a residual effect of an earlier injury.
• Ensure documentation clearly links the current condition to a previous subluxation event.
• Do not use this code for acute or initial encounters of a subluxation; those require different seventh characters.
