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 healthplanprovrelations@mgb.org.

Medicare Balance plans

Medicare Balance provides secondary coverage to Medicare — all members are required to have both Medicare Parts A and B. Medicare Balance does not have a provider network, so members may choose to see any doctor, anywhere in the nation, who accepts Medicare. Medicare Balance members don't need a referral to see a specialist.

ID_03_Medicare_Balance_1223

Claims information

For billing purposes, Medicare should be listed as the member's primary coverage and Medicare Balance as their secondary coverage. Also, Medicare Balance pays the entire balance on member deductibles and coinsurance costs for services charged at the Medicare-allowed amount. So, you don't have to collect any out-of-pocket fees from your patients.
