Medicare Advantage plans
Medicare Advantage is a bundled plan option that adds additional coverage to Original Medicare. Original Medicare (Parts A and B) includes hospital insurance for both inpatient and home health, and medical insurance for doctor visits and some preventive care. Medicare Advantage (Part C) plans combine Part A, Part B, and often Part D (drug coverage), to provide members with full-coverage benefits including dental, vision, hearing, and more
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.
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.
