CMS Pub. 100-08, ch. 10, § 10.3.1.1.4
Section 4 (Practice Location Information) - Form CMS-855A
A. General Background
Unless CMS specifies otherwise, any change in the provider’s phone number or address that the
provider did not cause (i.e., area code change, municipality renames the provider’s street) must
still be updated via the Form CMS-855.
Any provider submitting a Form CMS-855A application must submit the 9-digit ZIP Code for
each practice location listed.
(For paper applications only - If a practice location (e.g., hospital unit) has a CMS Certification
Number (CCN) that is in any way different from that of the main provider, the contractor shall
create a separate enrollment record in PECOS for that location. (This does not apply, however,
to home health agency (HHA) branches, outpatient physical therapy/outpatient speech pathology
(OPT/OSP) extension sites, and transplant centers.))
The contractor shall verify that the practice locations listed on the application actually exist and
are valid addresses with the United States Postal Service (USPS). PECOS includes a USPS
Address Matching System Application Program Interface (API), which validates address
information entered and flags the address if it is determined to be invalid, unknown,
undeliverable, vacant, unlikely to deliver mail (No-Stat), a CMRA (i.e., UPS Store, mailboxes,
etc.), or a known invalid address false positive. These address types are not permitted in PECOS
and are flagged upon entry.
The contractor need not verify the provider’s telephone number listed on the application, though
the provider must report one. If it does not, the contractor shall develop for a phone number
using the procedures outlined in this chapter.
If the contractor cannot verify the provider’s address, the contractor shall request clarifying
information from the provider. If the provider states that the facility is not yet operational, the
contractor may continue processing the application. However, it shall indicate in its
recommendation letter that the address of the facility could not be verified. For purposes of
PECOS entry, the contractor can temporarily use the date the certification statement was signed
as the effective date.
(For paper applications only: In Section 4A of the Form CMS-855A, if the “type of practice
location” checkbox is blank, the contractor can confirm the information via the PCV, e-mail, or
fax.)
B. Do Not Forward (DNF)
Unless instructed otherwise in another CMS directive, the contractor shall follow the DNF
initiative instructions in Pub. 100-04, chapter 1, section 80.5. Returned paper checks, remittance
notices, or EFT payments shall be flagged if returned from the post office or banking institution,
respectively, as this may indicate that the provider’s “special payment” address (in the Practice
Location Information section of the Form CMS-855A) or EFT information has changed. The
provider should submit a Form CMS-855A to change this address; if the provider does not have
an established enrollment record in PECOS, it must complete an entire Form CMS-855A and
Form CMS-588.
If the provider is closing its business and has a termination date, the contractor will likely need to
make payments for prior services rendered. Since the practice location has been terminated, the
contractor may encounter a DNF message. If so, the contractor should request the provider to
complete the “special payment” address section of the Form CMS-855A and to sign the
certification statement. The contractor, however, shall not collect any other information unless
there is a need to do so or unless an instruction in this chapter states otherwise. (See section
10.6.1.3(C)(5) of this chapter for additional information.)
C. Remittance Notices/Special Payments
For new enrollees, all payments must be made via EFT. The contractor shall thus ensure that the
provider has completed and signed the Form CMS-588 and shall verify that the bank account
complies with Pub. 100-04, chapter 1, section 30.2.
If an enrolled provider that currently receives paper checks submits a Form CMS-855A change
request (no matter what the change involves), the provider must also submit a Form CMS-588
that switches its payment mechanism to EFT. (The change request cannot be processed until the
Form CMS-588 is submitted.) All future payments (excluding special payments) must be made
via EFT; once a provider changes its method of payment from paper checks to EFT, it must
continue using EFT. A provider cannot switch from EFT to paper checks. The contractor shall
verify that the bank account complies with Pub. 100-04, chapter 1, section 30.2.
The “special payment” address may only be one of the following:
(i) One of the provider’s practice locations
(ii) A P.O. Box
(iii) The provider’s billing agent. (The contractor shall request additional information if it has
any reason to suspect that the arrangement – at least with respect to any special payments that
might be made – may violate the Payment to Agent rules in Pub. 100-04, chapter 1, section
30.2.)
(iv) The chain home office address. Per Pub.100-04, chapter 1, section 30.2, a chain
organization may have payments to its providers sent to the chain home office. The provider
must list the chain home office’s LBN on the Form CMS-588. The TIN on the Form CMS-588
should be that of the provider.
(v) Correspondence address
(vi) A lockbox. (The contractor shall request additional information if it has any reason to
suspect that the arrangement, at least with respect to any special payments that might be made,
may violate the Payment to Agent rules in Pub. 100-04, chapter 1, section 30.2.)
D. Out-of-State Practice Locations
If a provider is adding a practice location in another state that is within the contractor’s
jurisdiction -- and, for PECOS applications, to the extent PECOS permits it --- a separate, initial
Form CMS-855A enrollment application is not required if all of the following conditions are
met:
(i) The location is not part of a separate organization (e.g., a separate corporation, partnership);
(ii) The location does not have a separate TIN and LBN;
(iii) The state in which the new location is being added does not require the location to be
surveyed;
(iv) Neither the new location nor its owner is required to sign a separate provider agreement;
and
(v) The provider type in question is not required to separately enroll each of its practice
locations. (For example, a federally qualified health center (FQHC) would not meet this criterion
because FQHCs must separately enroll each location.)
Consider the following examples:
EXAMPLE 1 - The contractor’s jurisdiction consists of States X, Y and Z. Jones Health Care
Facility (JHCF), Inc. is enrolled in State X with 3 sites. It wants to add a fourth site in State Y.
The new site will be under JHCF, Inc. JHCF will not be establishing a separate corporation,
LBN, or TIN for the site, and - per the state and CMS policy - a separate survey and provider
agreement are not necessary; moreover, CMS policy does not require this provider type to
separately enroll each of its practice locations. Since all 5 conditions above are met, JHCF, Inc.
can add the fourth location via a change of information request, rather than an initial application.
The change request must include all information relevant to the new location (e.g., licensure,
new managing employees). (For paper applications only---and to the extent required---the
contractor shall create a separate PECOS enrollment record for the State Y location.)
EXAMPLE 2 - The contractor’s jurisdiction consists of States X, Y and Z. JHCF, Inc., is
enrolled in State X with 3 locations. It wants to add a fourth location in State Y but under a
newly created, separate legal entity - JHCF, LP. The fourth location must be enrolled via a
separate, initial Form CMS-855A.
EXAMPLE 3 - The contractor’s jurisdiction consists of States X, Y and Z. Jones Health
Services (JHS), Inc., is enrolled in State X with 1 location. It wants to add a second location in
State Z under JHS, Inc. However, it has been determined that a separate survey and certification
of the new location are required. A separate, initial Form CMS-855A for the new location is
required.
E. Additional Practice Location Information
1. Special Payments
In the “Practice Location Information/Where Do You Want Remittance Notices or Special
Payments Sent” section, if neither box is checked and no address is furnished, the contractor can
contact the provider by telephone, e-mail, the PCV, or fax to confirm the provider’s intentions.
If the provider replies that the “special payments” address is the same as the practice location, no
further development is needed. If, however, the provider wants payments sent to a different
address, the provider must furnish this address in the “Where Do You Want Remittance Notices
or Special Payments Sent” section of the Form CMS-855A.
Note that the provider/supplier can only have one special payment address per enrollment for
both PECOS and paper applications. See section 10.3(C)(2)(b) for more information.
2. Base of Operations
In the Practice Location Information/Base of Operations section, if the “Check here” box is not
checked and no address is furnished, the contractor can contact the provider by telephone, e-mail, the PCV, or fax to confirm the provider’s intentions. If the provider replies that the base of
operations address is the same as the practice location, no further development is needed. If the
provider indicates that the base of operations is at a different location, the provider must furnish
this address in the Base of Operations section of the Form CMS-855A.
3. Vehicle Information
In the Practice Location Information/Vehicle Information section, if the vehicle certificates are
furnished but the applicable Form CMS-855A sections are blank, the contractor can verify via
telephone, the PCV, e-mail, or fax that said vehicles are the only ones the provider has.
4. Primary Practice Location (PPL) Checkboxes
The provider must identify one – but no more than one – of the practice locations it lists in
Section 4(A) as its PPL. If the provider identifies multiple PPLs or no PPLs, the contractor shall
develop for additional information/clarification consistent with the instructions in Chapter 10. If
the provider lists multiple practice locations, identifies one of them (e.g., Location A) as its PPL,
and fails to check the PPL boxes for the other listed locations (Locations B, C, and D), the
contractor can assume --- absent evidence to the contrary -- that Location A is the PPL and need
not require the provider to check “No” for the PPL checkboxes for Locations B, C, and D.
5. Date First Patient Seen
For each practice location listed in Section 4(A), the provider must identify the date (month, day,
and year) on which the first patient was or will be seen. If the provider fails to submit this data,
the contractor shall develop for it consistent with the procedures in this chapter.
6. Medical Record Storage
In Section 4(C)(2), the provider must check whether it stores its patient medical records
electronically and, if it checks “Yes,” identify the service used to store these records. In the latter
case, an actual website need not be disclosed. Only a general reference to the type of electronic
storage is required (e.g., in-house software program, online service, vendor, etc.). It lies within
the contractor’s discretion to determine whether the description – which, again, need only be
general in nature – adequately identifies the type of electronic service; if an inadequate
description is furnished, the contractor shall develop for it consistent with the procedures in this
chapter. Moreover, if a website is listed, the contractor need not access it to verify that the link is
indeed where the records are stored.
7. Provider-Based
If the provider checks the “Outpatient Provider-Based Department” (PBD) box in Section 4(A),
it must check one of the seven succeeding checkboxes that outlines the type of PBD involved.
Except if CMS directs otherwise, the contractor need not verify any of the furnished PBD data in
Section 4(A), including whether the department is indeed a PBD or the type of PBD involved. In
addition, even if the contractor knows the department is provider-based, the provider need not
check that it is a PBD. Only if the provider checks the PBD checkbox must it also identify the
type.
