Medicaid Administrative Claiming (MAC)

What is MAC?

MAC is a program available for governmental entities that interact with individuals who are, or may be, eligible for Washington Apple Health (Medicaid). Partial reimbursement is available for the time that governmental entities spend helping individuals:

  • Apply for Apple Health (Medicaid), including renewals.
  • Explaining the Apple Health (Medicaid) program.
  • Helping individuals access Apple Health (Medicaid) services.

How can I participate?

To participate in the program, you must:

  • Be a governmental entity.
  • Be contracted with the Health Care Authority.
  • Participate in a time study designed to identify the percent of time you spend performing the Medicaid administrative activities listed above.

What and how much is reimbursed?

HCA will partially reimburse the staff salary and benefits that you expend while performing these activities. Only the Medicaid-related portion of these costs is allowable for federal reimbursement.

HCA reimburses MAC contractors with federal funds, using the Federal Financial Participation rate. The final reimbursement will be 50 percent (or 75 percent) of the expenses after they are reduced by:

  1. Random moment time study results.
  2. The percent of individuals served who are Apple Health (Medicaid) eligible.
  3. Other calculations of the claiming process.

Current MAC programs

We may develop new MAC programs. If you are seeking information about MAC for governmental entities not listed above, contact our office.

Important information

The Centers for Medicare and Medicaid Services is the federal agency with national oversight of the Medicaid program, including Medicaid Administrative Claiming.

Cost Allocation Plan

In order for HCA to operate a MAC program, a Cost Allocation Plan must be developed and approved by the Centers for Medicare and Medicaid Services. The Cost Allocation Plan describes how we will administer the program and ensure the federal funds are monitored and distributed appropriately.
