Internet-Only Manuals (IOMs)

The Internet-only Manuals (IOMs) are a replica of the Agency's official record copy. They are CMS' program issuances, day-to-day operating instructions, policies, and procedures that are based on statutes, regulations, guidelines, models, and directives. The CMS program components, providers, contractors, Medicare Advantage organizations and state survey agencies use the IOMs to administer CMS programs. They are also a good source of Medicare and Medicaid information for the general public.
