What 01840 covers
This code covers anesthesia for arterial procedures involving the forearm, wrist, or hand when the procedure does not fit a more specific arterial category. An anesthesiologist or CRNA reports the anesthesia service in the operative or procedural setting. Arterial embolization and vascular shunt procedures have nearby anesthesia codes with more specific descriptions.
The operative report should identify the arterial procedure and body site, and the anesthesia record should support the service and anesthesia time. Medicare assigns this code 6 base units and pays base units plus time units multiplied by the locality’s anesthesia conversion factor. Time is reported in minutes and converted to 15-minute units to one decimal place; it begins with anesthesia preparation and ends when the practitioner is no longer personally attending and the patient can safely be placed under postoperative care.

01840 billing questions
When should 01840 be chosen instead of 01842?
Use 01842 for anesthesia for arterial embolization of the forearm, wrist, or hand. Use 01840 for other arterial procedures in those regions that are not described by a more specific code.
How does 01840 differ from 01844?
01844 is for anesthesia for vascular shunt or shunt revision procedures. 01840 covers other arterial procedures of the forearm, wrist, or hand.
How are Medicare anesthesia units calculated for 01840?
The code has 6 base units. Medicare adds time units, calculated from reported anesthesia minutes in 15-minute units to one decimal place, then applies the locality’s anesthesia conversion factor.
What should the records show?
The operative report should identify the arterial procedure and its site in the forearm, wrist, or hand. The anesthesia record should support the anesthesia service and the start and end of anesthesia time.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
