[§482.26 Condition of Participation: Radiologic Services

§482.26(a) Standard: Radiologic Services
The hospital must maintain, or have available, radiologic services according to the needs of
the patients.
Interpretive Guidelines §482.26 (a)
Mandatory and Optional Radiologic Services
The hospital must maintain, or have available, diagnostic radiological services according to the
needs of the volume and types of patients the hospital serves. “Maintain” in this context means
furnishing radiologic services on-site, while having them available means providing access to
radiologic services even when they are not furnished on-site. For example:
• It would not be uncommon for a psychiatric hospital to maintain on-site relatively limited or
no radiologic services, while making more extensive diagnostic services available under
arrangement, at a site outside the psychiatric hospital.
• On the other hand, a short-term acute care hospital with a busy emergency department that
handles trauma, stroke, and other complex medical and surgical cases would be expected to
maintain on-site a wider range of diagnostic radiologic services that are ready to be furnished
when needed.
A hospital’s diagnostic radiologic services must be maintained or available at all times. Multi-campus hospitals must have diagnostic radiologic services that can be furnished when needed in
a clinically appropriate timeframe for each location providing inpatient, same-day surgery, and
emergency services. The scope and complexity of diagnostic radiological services maintained or
available must be specified in writing, in order to demonstrate how the hospital meets the needs
of its patients.
Therapeutic radiologic services are optional, but if they are offered, must also comply with the
Radiologic Services requirements.
Radiological services may be provided by the hospital directly utilizing its own staff, or through
a contractual arrangement. The hospital is responsible for ensuring that the services meet all the
requirements of this regulation, regardless of whether they are provided directly or under
arrangement. Diagnostic radiologic services provided under arrangement may be provided either
on the hospital’s campus or in an adjacent or other nearby, readily accessible facility so long as
the services, including those required on an urgent or emergent basis, can be furnished within
clinically appropriate timeframes.
Increasingly, hospitals are also separating the performance of radiologic studies, which may be
done on-site or at a readily accessible facility off the hospital’s campus, from the interpretation
of the studies, which can be performed remotely by a teleradiology practitioner in a timely
fashion. This practice is acceptable, so long as the teleradiology practitioner is privileged in
accordance with the requirements of the Governing Body (§482.12) and Medical Staff (§482.22)
CoPs.
Survey Procedures §482.26(a)
• With respect to assessing whether the diagnostic radiologic services meet the needs of the
hospital’s patients:
• Ask the hospital for evidence of the scope and complexity of its diagnostic radiologic
services.
• Ask how the hospital has determined that the services meet the needs of its patients.
• Verify that the hospital either maintains or makes available diagnostic radiologic services
that can be provided promptly when needed.
• If the hospital has an emergency department, are diagnostic radiologic services
maintained or available at all times to support the emergency department?
• If the diagnostic radiologic services are not on the same campus as the hospital’s
emergency department, same-day surgery, inpatient locations, or other areas where
services dependent upon radiologic services are provided, ask the hospital how it ensures
that services are furnished within clinically required timeframes. Does the hospital have
an arrangement with an off-site facility to furnish diagnostic services when needed?
• How does the hospital ensure that staff authorized to interpret diagnostic studies are
ready to furnish services within clinically required timeframes, either on-site or through
telecommunications media that permit remote review and interpretation of studies?
