Medicare Benefit Policy Manual (Pub. 100-02), Ch. 6 § 20.5.2
Coverage of Outpatient Therapeutic Services Incident to a
20.5.2 - Coverage of Outpatient Therapeutic Services Incident to a
Physician’s Service Furnished on January 1, 2010 through December
31, 2019
(Rev.267, Issued: 02-04-2020, Effective: 01-01-2020, Implementation: 01-06-2020)
Therapeutic services and supplies which hospitals provide on an outpatient basis are
those services and supplies (including the use of hospital facilities and drugs and
biologicals that cannot be self-administered) which are not diagnostic services, are
furnished to outpatients incident to the services of physicians and practitioners and which
aid them in the treatment of patients. These services include clinic services, emergency
room services, and observation services. Policies for hospital outpatient therapeutic
services furnished incident to physicians’ services differ in some respects from policies
that pertain to “incident to” services furnished in office and physician-directed clinic
settings. See Chapter 15, “Covered Medical and Other Health Services,” Section 60.
To be covered as hospital outpatient therapeutic services, the services and supplies must
be furnished by the hospital or CAH or under arrangement made by the hospital or CAH
(see section 20.1.1 of this chapter). The services and supplies must be furnished as an
integral, although incidental, part of the physician or nonphysician practitioner’s
professional service in the course of treatment of an illness or injury.
The services and supplies must be furnished in the hospital or at a department of the
hospital that has provider-based status in relation to the hospital under 42 CFR 413.65.
For therapeutic services furnished during CY 2010, as specified at 42 CFR 410.27(g), "in
the hospital or CAH" means areas in the main building(s) of the hospital or CAH that are
under the ownership, financial, and administrative control of the hospital or CAH; that
are operated as part of the hospital or CAH; and for which the hospital or CAH bills the
services furnished under the hospital’s or CAH’s CMS Certification Number.
Hospital outpatient therapeutic services and supplies must be furnished under the order of
a physician or other practitioner practicing within the extent of the Act, the Code of
Federal Regulations, and State law. They must be furnished by hospital personnel under
the appropriate supervision of a physician or nonphysician practitioner as required in this
manual and by 42 CFR 410.27 and 482.12. This does not mean that each occasion of
service by a nonphysician need also be the occasion of the actual rendition of a personal
professional service by the physician responsible for care of the patient. However, during
any course of treatment rendered by auxiliary personnel, the physician must personally
see the patient periodically and sufficiently often to assess the course of treatment and the
patient’s progress and, when necessary, to change the treatment regimen. A hospital
service or supply would not be considered incident to a physician’s service if the
attending physician merely wrote an order for the services or supplies and referred the
patient to the hospital without being involved in the management of that course of
treatment.
CMS requires direct supervision (defined below) by an appropriate physician or non-
physician practitioner in the provision of all therapeutic services to hospital outpatients,
including CAH outpatients. CMS may assign certain hospital outpatient therapeutic
services either general supervision or personal supervision. When such assignment is
made, “general supervision” means the definition specified at 42 CFR 410.32(b)(3)(i),
that is, the procedure or service is furnished under the physician's overall direction and
control, but the physician's presence is not required during the performance of the
procedure. “Personal supervision” means the definition specified at 42 CFR
410.32(b)(3)(iii), that is, the physician must be in attendance in the room during the
performance of the service or procedure.
Effective January 1, 2011 through December 31, 2019, hospitals may change to general
supervision for a portion of services defined as non-surgical extended duration
therapeutic services (“extended duration services”) but only as specified in this manual
for those services (see section 20.7). Pulmonary rehabilitation, cardiac rehabilitation, and
intensive cardiac rehabilitation services require direct supervision which must be
furnished by a doctor of medicine or osteopathy, as specified at 42 CFR 410.47 and
410.49, respectively.
The list of services for the period of January 1, 2010 through December 31, 2019 that
may be furnished under general supervision or that are defined as non-surgical extended
duration therapeutic services is available on the OPPS Website at
http://www.cms.gov/Medicare/Medicare-Fee-for-Service-
Payment/HospitalOutpatientPPS/index.html.
Beginning January 1, 2010, according to 42 CFR 410.27, in addition to physicians and
clinical psychologists, licensed clinical social workers, physician assistants, nurse
practitioners, clinical nurse specialists, and certified nurse-midwives may furnish the
required supervision of hospital outpatient therapeutic services that they may personally
furnish in accordance with State law and all additional rules governing the provision of
their services, including those specified at 42 CFR Part 410. These nonphysician
practitioners are specified at 42 CFR 410.27(g).
Considering that hospitals furnish a wide array of very complex outpatient services and
procedures, including surgical procedures, CMS would expect that hospitals already have
the credentialing procedures, bylaws, and other policies in place to ensure that hospital
outpatient services furnished to Medicare beneficiaries are being provided only by
qualified practitioners in accordance with all applicable laws and regulations. For
services not furnished directly by a physician or nonphysician practitioner, CMS would
expect that these hospital bylaws and policies would ensure that the therapeutic services
are being supervised in a manner commensurate with their complexity, including
personal supervision where appropriate.
For therapeutic services furnished during CY 2010 in the hospital or CAH or in an on-
campus outpatient department of the hospital or CAH, as defined at 42 CFR 413.65,
“direct supervision” means that the physician or nonphysician practitioner must be
present on the same campus where the services are being furnished. For services
furnished in an off-campus provider based department as defined in 42 CFR 413.65, he or
she must be present within the off-campus provider based department. The physician or
nonphysician practitioner must be immediately available to furnish assistance and
direction throughout the performance of the procedure. The physician or nonphysician
practitioner does not have to be present in the room when the procedure is performed.
For therapeutic services furnished during CY 2011 and following, whether in the hospital
or CAH or in an on-campus or off-campus outpatient department of the hospital or CAH
as defined at 42 CFR 413.65, “direct supervision” means that the physician or
nonphysician practitioner must be immediately available to furnish assistance and
direction throughout the performance of the procedure. As discussed below, the
physician is not required to be present in the room where the procedure is performed or
within any other physical boundary as long as he or she is immediately available.
Immediate availability requires the immediate physical presence of the supervisory
physician or nonphysician practitioner. CMS has not specifically defined the word
“immediate” in terms of time or distance; however, an example of a lack of immediate
availability would be situations where the supervisory physician or nonphysician
practitioner is performing another procedure or service that he or she could not interrupt.
Also, for services furnished on-campus, the supervisory physician or nonphysician
practitioner may not be so physically distant on-campus from the location where
hospital/CAH outpatient services are being furnished that he or she could not intervene
right away. The hospital or supervisory practitioner must judge the supervisory
practitioner’s relative location to ensure that he or she is immediately available.
For services furnished in CY 2011 and following, a supervisory practitioner may furnish
direct supervision from a physician office or other nonhospital space that is not officially
part of the hospital or CAH campus where the services are being furnished as long as he
or she remains immediately available. Similarly, as of CY 2011, an allowed practitioner
can furnish direct supervision from any location in or near an off-campus hospital or
CAH building that houses multiple hospital provider-based departments where the
services are being furnished as long as the supervisory practitioner is immediately
available.
The supervisory physician or nonphysician practitioner must have, within his or her State
scope of practice and hospital-granted privileges, the knowledge, skills, ability, and
privileges to perform the service or procedure. Specially trained ancillary staff and
technicians are the primary operators of some specialized therapeutic equipment, and
while in such cases CMS does not expect the supervisory physician or nonphysician
practitioner to operate this equipment instead of technician, CMS does expect the
physician or nonphysician practitioner to be knowledgeable about the therapeutic service
and clinically able to furnish the service.
The supervisory responsibility is more than the capacity to respond to an emergency, and
includes the ability to take over performance of a procedure or provide additional orders.
CMS would not expect that the supervisory physician or nonphysician practitioner would
make all decisions unilaterally without informing or consulting the patient’s treating
physician or nonphysician practitioner. In summary, the supervisory physician or
nonphysician practitioner must be clinically able to supervise the service or procedure.
