Thank you for your patience as we investigated authorization denials being sent to providers who have submitted lab, radiology, mammograms, and OB/GYN services, which normally do not require an authorization. We have determined a system error caused claims to deny with a denial code of 210 between November 1, 2022, and December 22, 2022. The error was corrected as of December 22, 2022.


Unfortunately, the December 2022 correction was not broad enough to capture the full scope of the error. For example, office visits requiring a copayment by a member continued to be impacted. An expanded error correction went into place on February 23, 2023.


We are now working on reprocessing claims that were denied incorrectly between November 1, 2022, and February 23, 2023. Anthem Blue Cross and Blue Shield (Anthem) is treating this reprocessing effort as a high priority. Anthem will begin creating impact reports and reprocessing of the incorrectly denied claims the week of February 27, 2023. Our reprocessing will include adding on any penalties and interest, as applicable, that may be due to providers under Colorado law or our contracts. We anticipate that the majority of the claim reprocessing should be completed by the end of March 2023. Providers do not need to take any further action on these claims. However, we understand if you want to reach out for any updates we can provide in the meantime. 


If you received what you believe to be an incorrect denial for an authorization on a claim with a process date after February 23, 2023, please let us know.


If you are receiving authorization denials for MRI/CT with denial code 197, these are most likely appropriate denials and authorization should go through Carelon Medical Benefits Management, Inc.* (previously known as AIM Specialty Health). 


Please use one of the following options to see if a prior authorization is required:

  • Authorization list:
