How OHP worksWhen do State Plan Amendments become effective?

Once CMS approves a SPA, the changes can take effect retroactive to the first day of the quarter of the federal fiscal year in which the SPA was submitted. These procedures can make the SPA approval process quite lengthy.

How OHP worksWhat is a State Plan Amendment?

When a state wants to change any of the Medicaid  benefits it offers, or change the way in which services are offered, it must  submit a State Plan Amendment (SPA).​

How OHP worksWhat is a State Plan?
Under Section 1902 of the Social Security Act, all states must comply with some basic requirements. For example, each state must:
  • Serve certain mandatory populations, such as poverty-level children and low-income pregnant women.
  • Provide certain mandatory services, such as hospital care and physician services.
  • Provide services that are "sufficient in amount, duration, and scope to reasonably achieve (their) purpose."
  • Provide services throughout the state.
A State Plan outlines how each state will meet these requirements. Once CMS approves the original Plan, they must also approve all future changes to the Plan before any changes become effective.

A state can also request CMS to waive certain federal requirements to allow greater flexibility or expand the Medicaid populations it serves.

The CMS website provides more information about Medicaid and CHIP State Plans and Medicaid demonstration waivers.

How OHP worksWhat happens when a state submits a State Plan Amendment to CMS?
Once the CMS Regional Office receives a SPA, it has 90 calendar days to approve or deny the SPA, or send a formal Request for Additional Information (RAI) letter.
Once the CMS Regional Office receives a SPA, it has 90 calendar days to approve or deny the SPA, or send a formal Request for Additional Information (RAI) letter.
Sending an RAI stops the 90-day clock. The clock will not start again until CMS receives the state's written response to the RAI. Another 90-day clock starts at this point.

Throughout this process, CMS has the option of asking informal questions via e-mail or phone.
