Subluxation of oth carpometacarpal joint of left hand, subs

This code signifies a partial dislocation of a carpometacarpal joint in the left hand, excluding the thumb carpometacarpal joint. It indicates that the patient is receiving follow-up care for this injury after the initial treatment phase.

Use this code for patients presenting for cast changes, physical therapy, or medication refills related to a previously diagnosed subluxation of a non-thumb carpometacarpal joint of the left hand. This applies when the initial treatment has concluded, and the patient is in the healing or recovery phase.

• Ensure the documentation specifies "left hand" and "other carpometacarpal joint" (not the thumb).
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing phase.
• Do not use for initial treatment (A) or sequela (S) encounters.
