CMS Pub. 100-08, ch. 10, § 10.3.1.6.1
Sections 1 through 13 – Form CMS-855S
A. Basic Information (Section 1)
In this section, the supplier indicates the reason for submittal of the application. Unless
otherwise stated in this chapter, in another CMS directive, or as permitted by PECOS, the
supplier may only check one reason for submittal. Additionally, the supplier will identify its
business and business location in this section.
B. Identifying Information (Section 2)
1. Locations and Addresses - Except for locations used only as warehouse and/or repair facilities,
the supplier must submit a completed Form CMS-855S application for each physical location.
Each address must be a street address as recorded by the USPS, and P.O. boxes will not be
accepted.
2. Hours – The supplier must list their posted hours of operation as displayed at the
aforementioned business location. Unless otherwise stated in this chapter or in another CMS
directive, the supplier shall have a minimum of 30 hours of operation per week.
3. Unavoidable Phone Number or Address Changes – Unless CMS specifies otherwise, any
change in the supplier’s phone number or address that the supplier did not cause (e.g., area code
change, municipality renames the supplier’s street) must still be updated via the Form CMS-
855S.
See section 10.2.5 of this chapter for information on accreditation requirements.
C. Final Adverse Legal Actions (Section 3)
See section 10.6.6 of this chapter for information regarding final adverse actions. Except as
otherwise stated, the PECOS policies in section 10.3 supersede those in section 10.6.6 (e.g.,
communicating with the supplier via the PCV).
D. Important Address Information (Section 4)
See the Important Address Information section of the Form CMS-855S for more background on
this matter.
E. Ownership Interest and/or Managing Control Information (Organizations) (Section 5)
See section 10.6.7 et seq. of this chapter for information concerning owning and managing
organizations.
F. Ownership Interest and/or Managing Control Information (Individuals) (Section 6)
See section 10.6.7 et seq. of this chapter for information concerning owning and managing
individuals.
G. Comprehensive Liability Insurance Information and Surety Bond Information (Section
7)
See section 10.2.5 of this chapter for information regarding comprehensive liability insurance
and surety bond information.
H. Billing Agency Information (Section 8)
(See section 10.6.8 of this chapter for more information on billing agencies. Except as otherwise
stated, the PECOS policies in section 10.3 above supersede those in section 10.6.8.)
If the telephone number in the Billing Agency Information section is blank, the number can be
verified with the supplier by telephone, the PCV, e-mail, or fax. If the entire section is blank
(including the check box), no additional development is necessary.
I. Supporting Documents (Section 12)
See the Supporting Documents section of the Form CMS-855S for information concerning
supporting documents.
J. Contact Person Information (Section 13)
If this section is completely blank, the contractor need not develop for this information and can
simply contact an authorized or delegated official.
If neither box is checked but the contact person information is incomplete (e.g., no telephone
number listed), the contractor can either: (1) develop for this information by telephone, the PCV,
e-mail, or fax; or (2) contact an authorized or delegated official.
There is no existing option on the Form CMS-855S to delete a contact person. The contractor
shall therefore accept end-dates of a contact person via telephone, the PCV, e-mail, fax, or mail
from the individual supplier, the authorized or delegated official, or a current contact person on
file. The contractor shall document in PECOS who requested the termination, how it was
requested (email, phone or fax), and when it was requested. The addition of contact persons
must still be reported via the appropriate Form CMS-855S.
See section 10.6.9 of this chapter for more information on contact persons. Except as otherwise
stated, the PECOS policies in section 10.3 above supersede those in section 10.6.9.
K. Penalties for Falsifying Information (Section 14)
See the Penalties for Falsifying Information section of the Form CMS-855S for an explanation of
penalties that apply to suppliers for deliberately furnishing false information in this application to
gain or maintain enrollment in the Medicare program.
