§485.610(e) Standard: Off-campus and Co-Location Requirements for CAHs
(1) If a CAH with a necessary provider designation is co-located (that is, it
shares a campus, as defined in §413.65(a)(2) of this chapter, with another
hospital or CAH), the necessary provider CAH can continue to meet the
location requirement of paragraph (c) of this section only if the co-location arrangement was in effect before January 1, 2008, and the type
and scope of services offered by the facility co-located with the necessary
provider CAH do not change. A change of ownership of any of the
facilities with a co-location arrangement that was in effect before January
1, 2008, will not be considered to be a new co-location arrangement.
(3) If either a CAH or a CAH that has been designated as a necessary
provider by the State does not meet the requirements in paragraph (e)(1)
of this section, by co-locating with another hospital or CAH on or after
January 1, 2008, [or creates or acquires an off-campus provider-based
location or off-campus distinct part unit on or after January 1, 2008, that
does not meet the requirements in paragraph (e)(2) of this section,] the
Standard: Off-campus and co-location requirements for CAHs. A CAH may
continue to meet the location requirement of paragraph(c) of this section based only
if the CAH meets the following:
CAH’s provider agreement will be subject to termination in accordance
with the provisions of §489.53(a)(3) of this subchapter, unless the CAH
terminates the off-campus arrangement or the co-location arrangement,
or both.
Interpretive Guidelines §485.610(e)(1) & (3)
A CAH may not be co-located with another hospital or CAH, because this would violate
the minimum distance requirement found at §485.610(c). However, some CAHs that
were designated as necessary providers prior to January 1, 2006, and therefore exempted
from this distance requirement, also chose to co-locate with another hospital. Co-location
occurs when a necessary provider CAH shares the same campus and/or building in which
the CAH is currently located with another hospital or necessary provider CAH. For
example, a necessary provider CAH shares the same campus with an unrelated
psychiatric or rehabilitation hospital.
Effective January 1, 2008, grandfathered necessary provider CAHs may no longer enter
into co-location arrangements with another CAH or hospital (72 FR 66878). However,
necessary provider CAHs that had co-location arrangements in effect prior to January 1,
2008, are permitted to continue these arrangements as long as the type and scope of
services offered by the facility co-located with the CAHs do not change. An example of
a change in type of services would be when a hospital that provides only rehabilitation
services chooses to provide general hospital acute care services. An example of a change
in scope of services would be when a grandfathered necessary provider CAH is currently
co-located with a 20 bed psychiatric hospital and the psychiatric hospital now decides to
increase the number of beds to 30.
The determination of whether or not CAHs with a grandfathered necessary provider
designation have met the requirements at §485.610(e)(1) is made by the RO. If the SA or
accreditation organization (AO) becomes aware of a co-location arrangement, the SA or
AO must notify the RO. The RO will utilize the co-location guidance in §2256G of the
SOM to determine if such CAHs satisfy the co-location requirements at §485.610(e)(1).
The RO will notify the CAH as well as the SA (and the AO, if applicable) of its
determination.
A CAH found out of compliance with the requirements is subject to termination of its
Medicare provider agreement under §489.53(a)(3). In such cases the CAH is placed on a
90-day termination track, as outlined in §3012 of the SOM. If the CAH corrects the
situation, by terminating the co-location arrangement that led to the non-compliance
during this 90 day period, then the provider agreement is not terminated.
A facility facing termination of its CAH designation as a result of non-compliance with
§485.610(e)(1) could also continue to participate in Medicare by converting to a hospital,
assuming that the facility satisfies all requirements for participation as a hospital in the
Medicare program under the provisions at 42 CFR Part 482. Under this scenario, the
CAH would apply to convert back to a hospital, with the effective date coinciding with
the date of termination of CAH status. A new CMS Certification Number (CCN) would
be assigned accordingly.
