What 01742 covers
01742 covers anesthesia for an open or arthroscopic operation that includes an osteotomy at the elbow. An osteotomy involves cutting bone; this code identifies the anesthesia service, not the surgeon’s operative work. An anesthesiologist or CRNA reports the anesthesia service for the operation, while the surgeon reports the operative procedure separately.
Choose 01742 for the elbow osteotomy category rather than 01740 for other open or arthroscopic elbow procedures, 01744 for humeral repair, 01756 for radial procedures, or 01758 for cyst excision. The operative report should establish the elbow osteotomy, and the anesthesia record should document start and end times. The code has 5 base units; Medicare payment is (base units + time units) multiplied by the locality’s anesthesia conversion factor. Time runs from when the anesthesia practitioner begins preparing the patient until personal attendance ends and the patient can safely be placed under postoperative care; minutes convert to 15-minute units, calculated to one decimal place.

01742 billing questions
When should I choose 01742 instead of 01740?
Use 01742 when the elbow operation includes an osteotomy. Use 01740 for other open or arthroscopic elbow procedures that do not fit a more specific anesthesia category.
How does 01742 differ from anesthesia for humeral repair?
01742 is for an elbow osteotomy. Compare the operative details with 01744 when the operation involves humeral repair instead.
What should the records show?
The operative report should establish that an elbow osteotomy was performed. The anesthesia record should document when preparation for anesthesia began and when personal attendance ended with the patient safe for postoperative care.
How are time units calculated for 01742?
Anesthesia time is reported in minutes and converted to 15-minute units, calculated to one decimal place. For example, 38 minutes equals 2.5 time units.
What are the base units and Medicare payment calculation?
01742 has 5 base units. Medicare calculates anesthesia payment using base units plus time units, multiplied by the anesthesia conversion factor for the payment locality.
