CMS issued guidance for state and local governments regarding receiving reimbursement from CMS programs (Medicare, Medicaid, CHIP) for care provided at an alternate care site. CMS advises that the easiest path is for an already-enrolled hospital or health system to treat the ACS as a temporary expansion of their “brick-and-mortar” location. In these circumstances, the local hospitals and health systems operate, staff, and bill for care furnished at the ACS. The guidance also describes the ways in which state and local governments that want to develop or build a hospital ACS may be paid by CMS for furnishing covered hospital inpatient and outpatient services.
