What 01820 covers
This code covers anesthesia for closed procedures involving the radius, ulna, wrist, or hand bones, commonly closed reduction of a fracture. An anesthesiologist or CRNA reports the anesthesia service for these procedures in a hospital or other operative setting. The operative approach—not simply the fact that the patient has a wrist or hand condition—determines whether this code fits.
Use this code for a closed bone procedure rather than anesthesia for soft-tissue work, wrist arthroscopy, or casting alone. The operative report should identify the treated bone and establish that the procedure was closed; the anesthesia record supports the anesthesia service and its time. This code has 3 base units; Medicare payment is (base units + time units) multiplied by the locality’s anesthesia conversion factor. Anesthesia time starts when the practitioner begins preparing the patient for anesthesia and ends when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care; minutes are converted to 15-minute units to one decimal place.

01820 billing questions
How does this code differ from wrist arthroscopy anesthesia?
Use this code for a closed procedure on radius, ulna, wrist, or hand bones. Anesthesia for wrist or hand arthroscopic or endoscopic work belongs under the applicable arthroscopy code, such as 01829 for diagnostic wrist arthroscopy.
Does a closed reduction of a wrist fracture fit this code?
Yes, when the procedure is a closed bone procedure involving the radius, ulna, wrist, or hand. The operative record should establish the bone treated and the closed approach.
Does anesthesia for casting alone belong here?
No. Anesthesia for forearm, wrist, or hand casting is identified separately by code 01860.
How are anesthesia units calculated for this code?
The code has 3 base units. Medicare adds time units, calculated from anesthesia minutes in 15-minute units to one decimal place, then multiplies the total by the locality’s anesthesia conversion factor.
What should the operative and anesthesia records support?
The operative report should show the specific bone or region treated and that the procedure was closed. The anesthesia record should support the reported anesthesia time, from preparation for anesthesia through the point the practitioner is no longer personally attending and the patient can safely enter postoperative care.
How does Medicare pay when an anesthesiologist medically directs a CRNA?
Medicare pays each practitioner 50% of the allowance for the personally performed service when the anesthesiologist medically directs the CRNA.
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.
