Coordination With Medicaid
110.2 - Coordination With Medicaid
(Rev. 1, 10-01-03)
A/B MACs (B) furnish copies of the fee schedules and the annual update (including
NLAs where applicable) to State agencies (SAs). A/B MACs (B) provide updates to SAs
at least 30 days prior to the scheduled implementation. To obtain Federal matching funds
for clinical laboratory services, State Medicaid agencies may not pay more than Medicare
pays for the services and specimen collections.
Since the fee schedule provisions were implemented on a carrier wide basis, a State may
have had more than one carrier servicing Medicare beneficiaries residing in the State. A
Medicaid agency for such a State may, if it deems necessary, use the fee schedules of
either one or both of the A/B MACs (B) to meet the Federal fund-matching requirement.
State Medicaid agencies may consult with ROs concerning the fee schedule, the NLAs,
and specimen collection provisions.
