What 01842 covers
This service covers anesthesia during surgery to remove an embolus from an artery in the forearm, wrist, or hand. An anesthesia practitioner, such as an anesthesiologist or CRNA, reports the anesthesia service; the surgeon performs the arterial procedure.
Choose this code for an arterial embolectomy in the covered region; other arterial procedures there use 01840, while vascular shunt or shunt-revision surgery is associated with 01844. The operative report should identify the treated artery and document embolus removal, and the anesthesia record should support the anesthetic service. This code has 6 base units. Medicare payment is (6 base units + time units) multiplied by the locality-specific anesthesia conversion factor; time starts when the practitioner begins preparing the patient for anesthesia and ends when personal attendance ends and the patient can safely be placed under postoperative care, with minutes converted to 15-minute units to one decimal place.

01842 billing questions
How do I distinguish 01842 from 01840?
Use 01842 when the operation removes an embolus from an artery of the forearm, wrist, or hand. Use 01840 for other arterial procedures in those regions.
Does 01842 describe embolization?
No. It covers anesthesia for surgical removal of an embolus, not embolization.
What documentation supports this code?
The operative report should establish that the procedure was an embolectomy and identify the treated artery in the forearm, wrist, or hand. The anesthesia record should support the service and its time.
How are time units calculated for Medicare?
Anesthesia time is reported in minutes and converted to 15-minute units, computed to one decimal place. Medicare payment uses this code’s 6 base units plus time units, multiplied by the locality’s anesthesia conversion factor.
