Important: Claims billed electronically between 03/31/2023 and 04/20/2023 with CPT codes G2023 and G2024 may have rejected. This is because the original CMS code termination date was 03/31/2023. CMS has revised the termination date from 03/31/2023 to 05/11/2023 (to coincide with the end of the COVID-19 Public Health Emergency). This update was noted in the COVID-19 Payment Policy.

While the official termination date of these codes of 05/11/23 is now in place, providers may need to resubmit claims that were originally submitted and rejected between 03/31/23 and 04/20/23. We apologize for any inconvenience. If you have any questions, please feel free to contact
