Dislocation of interphalangeal joint of left thumb, subs

This code signifies a dislocation affecting the joint between the phalanges of the left thumb. It specifically indicates that the patient is in the healing phase following the initial injury, requiring ongoing care or follow-up.

Apply this code for patients presenting for follow-up appointments, physical therapy, or re-evaluation of a previously treated interphalangeal joint dislocation of the left thumb. It is appropriate when the initial acute treatment has concluded and the focus is on recovery or monitoring.

• Ensure documentation clearly specifies the left thumb and the interphalangeal joint.
• Verify the encounter is for a subsequent visit, not the initial acute injury.
• Confirm the dislocation is not a fracture-dislocation, which would require a different code.
