Cost-Effective Alternative Services (In Lieu of)

Revised: November 2, 2023

Effective July 6, 2016, federal regulations allowed and clarified the use of cost-effective alternative services that are approved by the New York State (NYS or State) to be offered by Medicaid Managed Care Organizations (MMCOs). These regulations encourage innovation and promote efficiency and quality by enabling MMCOs to offer their enrollees physical and behavioral health services that are not covered under the Medicaid State Plan.

MMCOs may, as a cost-effective alternative to Medicaid State Plan services and settings, provide Medicaid Managed Care enrollees with alternative services and settings as permitted by 42 CFR 438.3(e)(2) and approved by the State and the Centers for Medicare and Medicaid Services (CMS). These cost-effective alternative services are often referred to as "in lieu of services" (ILS). The cost of such services must be included in the development of the MMCO rates.

ILS are defined as alternative services or settings that are not included in the Medicaid State Plan but are medically appropriate, cost-effective substitutes for covered services or settings.1 "State Approved ILS" means ILS proposed by an MMCO that has been approved by the State. "State Identified ILS" means ILS that has been identified by the State as appropriate ILS for the Medicaid Managed Care program. Both State Approved and State Identified ILS will be posted on State agency websites.

1. 42 CFR 438.3(e)(2).  1
2. Unless otherwise specified in statute or regulation, section 4442.3.B.12 of the State Medicaid Manual, defines "room" as hotel or shelter-type expenses, including all property-related costs (e.g., rental or purchase of real estate and furnishings, maintenance, utilities, and related administrative services) and defines "board" as three meals a day or any other full nutritional regimen.  2
3. MMCO's should utilize experience and knowledge of their enrolled populations and any research/findings available regarding the proposed ILS to best estimate or approximate the informationrequested. The State will use this information in its assessment of the MMCO's application; however, will not consider the estimates or approximations as binding for actual service delivery or outcomes.  3
