[
This is a reminder of the billing requirements for anesthesia services. 
Unless otherwise noted, time must be reported for anesthesia services in 
minutes. If the provider?s anesthesia service is interrupted for a short 
duration, the total number of minutes should be reported, less the number of 
minutes representing the interruption.
IBC applies the following standard anesthesia calculation formula to 
determine reimbursement for eligible anesthesia
services reported in minutes:
- Reported anesthesia time units ? 15 minutes (round the time units to one 
decimal place) = Time unit 
- Time unit + base unit + modifying unit (if applicable) x conversion factor 
= Reimbursement 
Do not report base units with an anesthesia procedure code because IBC 
calculates the reimbursement using the
Centers for Medicare & Medicaid Services anesthesia base units.
For additional information about billing for anesthesia services, refer to 
Claim Payment Policy #00.01.14: Reporting
and Documentation Requirements for Anesthesia Services, which is available at 
our IBC Medical Policy Portal.
