Billing CC 90 or 91

CMS issued MLN Matters® (MM) 12049 external pdf file to implement two new condition codes (CCs):
90 – To allow providers to report when the service is provided as part of an Expanded Access approval
91 – To allow providers to report when the service is provided as part of an Emergency Use Authorization (EUA)
First Coast would like to remind you of the implementation and effective dates for these new codes. The MM12049 was released on November 20, 2020, with an implementation date of February 22, 2021, and an effective date for claims received on or after February 1, 2021.
First Coast loaded the new CCs on February 10. This means the new codes were not in the Fiscal Intermediary Standard System (FISS) until February 10. Any claims submitted before February 10, with these new condition codes, were rejected prior to entering FISS.

Provider action

If you submitted claims before February 10, with either CC 90 or 91 and received a rejection, you can resubmit the claim.
