reported at the line level only when they are different from that identified at the claim
level. Therefore, there will be at least one referring provider identified at the claim level
on the ASC X12 837 Professional claim for therapy services. However, because of the
hierarchical nature of the ASC X12 837 health care claim transaction, and the possibility
of other types of referrals applying to the claim, the number of referring providers
identified on a professional claim may vary. For example, on a claim where one
physician/NPP has certified all the therapy plans of care, and there are no other referrals,
there would be only one referring provider identified at the claim level and none at the
line levels. Conversely, on a claim also containing a non-therapy referral made by a
different physician/NPP than the one certifying the therapy plan of care, the billing
provider may elect to identify either the nontherapy or the therapy referral at the claim
level, with the other referral(s) at the line levels. Similarly, on a claim having different
certifying physician/NPPs for different therapy plans of care, only one of these
physician/NPPs will be identified at the claim level, with the remainder identified at the
line levels. These scenarios are only examples: there may be other patterns of
representing referring providers at the claim and line levels depending upon the
circumstances of the care and the manner in which the provider applies the requirements
of the ASC X12 837 Professional Health Care Claim TR3.
For situations where the physician/NPP is both the certifier of the plan of care and
furnishes the therapy service, he/she supplies his/her own information, including the NPI,
in the appropriate referring provider loop (or, appropriate block on Form CMS 1500).
This is applicable to those therapy services that are personally furnished by the
physician/NPP as well as to those services that are furnished incident to their own and
delivered by “qualified personnel” (see section 230.5 of this manual for qualifications for
incident to personnel).
Contractors shall edit to ensure that there is at least one claim-level referring provider
identified on professional therapy claims, and shall use the presence of the therapy
modifiers (GN, GP, GO) to identify those claims subject to this requirement.
For the purposes of processing institutional claims, the certifying physician/NPP and their
NPI are reported in the Attending Provider fields on institutional claim formats. Since
the physician/NPP is certifying the therapy plan of care for the services on the claim, this
is consistent with the National Uniform Billing Committee definition of the Attending
Provider as “the individual who has overall responsibility for the patient’s medical care
and treatment” that is reported on the claim. In cases where a patient is receiving care
under more than one therapy plan of care (OT, PT, or SLP) with different certifying
physicians/NPPs, the second certifying physicians/NPP and their NPI are reported in the
Referring Physician fields on institutional claim formats.
