§ 424.20 Requirements for posthospital SNF care.
Medicare Part A pays for posthospital SNF care furnished by an SNF, or a hospital or CAH with a swing-bed approval, only if the certification and recertification for services are consistent with the content of paragraph (a) or (c) of this section, as appropriate.
(a) Content of certification—(1) General requirements. Posthospital SNF care is or was required because—
(i) The individual needs or needed on a daily basis skilled nursing care (furnished directly by or requiring the supervision of skilled nursing personnel) or other skilled rehabilitation services that, as a practical matter, can only be provided in an SNF or a swing-bed hospital on an inpatient basis, and the SNF care is or was needed for a condition for which the individual received inpatient care in a participating hospital or a qualified hospital, as defined in § 409.3 of this chapter, or for a new condition that arose while the individual was receiving care in the SNF or swing-bed hospital for a condition for which he or she received inpatient care in a participating or qualified hospital; or
(ii) The individual has been correctly assigned one of the case-mix classifiers that CMS designates as representing the required level of care, as provided in § 409.30 of this chapter.
