(4) The general public.
(c) Prior to submitting to the Centers for Medicare & Medicaid Services for approval a state plan amendment (SPA) to establish or substantially modify existing premiums or cost sharing, or change the consequences for non-payment, the agency must provide the public with advance notice of the SPA, specifying the amount of premiums or cost sharing and who is subject to the charges. The agency must provide a reasonable opportunity to comment on such SPAs. The agency must submit documentation with the SPA to demonstrate that these requirements were met. If premiums or cost sharing is substantially modified during the SPA approval process, the agency must provide additional public notice.
