Anesthesia Billing Reminder; Claims Reprocessing

To ensure proper billing, all anesthesia claims must specify the correct anesthesia modifier in the first modifier position on the claim, clearly identifying the provider of the anesthesia services. Effective March 29, 2025, Blue Cross Blue Shield of Kansas (BCBSKS) implemented a requirement for anesthesia claims to include the appropriate modifiers—AA, AD, QK, QX or QY.

Claims processed March 29 through July 31 that are denied for invalid modifier because of this change will be reprocessed. Claims processed after July 31 without the appropriate modifier, will need to be resubmitted as corrected claims to include the appropriate modifier.

If you have additional questions or concerns, please reach out to your provider relations representative.
