Subluxation of interphalangeal joint of left thumb, subs

This code signifies a partial dislocation of the joint within the left thumb, specifically between the phalanges. It indicates that the thumb bones are misaligned but still in partial contact, and the patient is in the healing phase following initial treatment.

Apply this code when documenting follow-up care for a patient who has previously received treatment for a subluxation of the left thumb's interphalangeal joint. This includes visits for rehabilitation, cast changes, or monitoring of healing progress after the initial injury and treatment.

• Ensure documentation specifies "left thumb" and "interphalangeal joint" to support this code.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use for initial treatment of the injury; refer to the "A" seventh character for active treatment.
