Information for Potential Medicaid Contractors

Aging and Long Term Supports Administration - ALTSA administers Medicaid state plan and 1915(c) waivers, and the 1115 Medicaid Transformation Demonstration - MTD waiver that provide an array of long term services and supports to adults with unmet needs for assistance with activities of daily living due to functional impairments caused by age, physical disability or cognitive impairment as well as services and supports to their unpaid family caregivers.

ALTSA contracts with 13 Area Agencies on Aging - AAA to develop maintain and ensure a quality statewide Medicaid provider network to serve clients who are eligible for Medicaid long term services and supports.  All applicants must meet the minimum qualifications to provide services.  A Medicaid contract does not guarantee referrals. 

Eligible clients may choose to receive services from any qualified provider of a particular service.  Providers do not determine eligibility for services.  All state plan and 1915(c) waiver services are authorized by DSHS Home and Community Services and Area Agency on Aging staff.  MTD services are authorized by Area Agency on Aging staff.  Providers must have adequate cash flow to provide services in advance of reimbursement.   

Service authorizations and payment for claims are completed through the Health Care Authority’s ProviderOne payment system.  Applicants who receive a Medicaid contract will be mailed a ProviderOne Enrollment Packet from the Health Care Authority.  Additional training and resources for ProviderOne can be found at training.  DSHS determines Home and Community Services Medicaid rates, which are posted here.

Application materials for a Home and Community Services Medicaid contract are submitted directly to the Area Agency on Aging.  Contract templates provided in the links below are examples that are used for most businesses structures.  Additional templates are available that may be more appropriate for some applicants (e.g., county governments, tribal nations, quasi-governments).  Applicants who receive a contract will be monitored by the Area Agency on Aging.
