Dislocation of MCP joint of left index finger, subs

This code signifies a dislocation of the joint connecting the metacarpal bone to the first phalanx of the left index finger. This specific code is used when the patient is receiving follow-up care for this injury after the initial treatment phase.

Apply this code when a patient presents for subsequent treatment, such as cast changes, physical therapy, or follow-up appointments, for a previously diagnosed and initially treated dislocation of the left index finger's MCP joint. It indicates that the acute phase of treatment has concluded.

• Ensure documentation clearly specifies the left index finger and that the encounter is not the initial treatment.
• Verify the "D" seventh character is appropriate for subsequent care, not initial or sequela.
• Confirm the injury is a dislocation, not a sprain or fracture, of the MCP joint.
