Vascular comp fol infusn, tranfs and theraputc inject, subs

This code signifies a patient presenting for follow-up care of a vascular complication that arose from an infusion, transfusion, or therapeutic injection. These complications can include issues like phlebitis, thrombosis, or hematoma at the injection site, or more systemic vascular reactions. The "D" in the seventh character indicates that this is a subsequent encounter for the management of the complication.

Use this code when a patient returns for ongoing treatment, monitoring, or evaluation of a vascular problem that was directly caused by a previous infusion, transfusion, or therapeutic injection. This applies to situations where the initial complication has already been diagnosed and the patient is no longer in the acute phase of treatment. Examples include follow-up for a resolving thrombophlebitis or management of a persistent hematoma.

• Always ensure the seventh character "D" is appended for subsequent encounters.
• Code also the specific nature of the vascular complication (e.g., phlebitis, thrombosis) if known and documented.
• Do not use this code for the initial treatment of the complication; refer to the "A" seventh character for initial encounters.
