The In-Home Supports Waivers (IHSW) were created in 1999 in response to the continually increasing numbers of individuals with developmental disabilities remaining on the waiver waiting list. The IHSW allow individuals and families to select services necessary for each individual to remain in his or her own home or family home. Individuals on the IHSW are assigned to OKDHS Developmental Disabilities Services Division (DDSD) case managers to assist them in locating, securing, and coordinating needed services.

Eligible children, ages 3 through 17, may receive up to $12,360 of services per year through the IHSW-Children.  Eligible adults, 18 years or older, may receive up to $18,540 of services per year through the IHSW-Adult.  These waivers are not cash payment programs and all services are provided through agencies contracting with the Oklahoma Health Care Authority. The IHSW-Children provides less funding than the IHSW-Adult because many services are already available to children through the Medicaid State Plan Early and Periodic Screening, Diagnosis and Treatment (EPSDT) Program and the Oklahoma Department of Human Services Disabled Children's Program (DCP).
