Section 1115 Waiver – In January 2004, the Centers for Medicare and Medicaid Services (CMS) approved a Medicaid Section 1115 waiver that would allow Montana to provide a limited Medicaid benefit package of optional services for Medicaid-eligible parents aged 21 through 64 who are not pregnant or disabled. The optional services were excluded to align coverage with typical employer-sponsored insurance. This waiver was based on a previous Montana waiver, which provided a limited Medicaid benefit package to adults who are neither disabled nor pregnant, under the authority of Montana’s welfare reform waiver in 1996.
