COMMINGLING
Commingling is being paid twice from Medicare for
the same service(s) and is considered fraud.
Since you are billing incident-to-services with the
professional component to Medicare Part A as an
RHC you cannot bill the same incident-to-services to
Medicare Part B to receive a second payment.
MEDICAID BILLING
Go into your state GOV website and find the RHC
department. Search for the RHC billing manual for
Medicaid in your state.
Some states require the Medicaid claims to be
submitted on 1500 claim forms and others require
Medicaid to be billed in the UB 04 format.
