CMS Pub. 100-08, ch. 10, § 10.4.1.3.4
Receiving Missing/Clarifying Data/Documentation (Response to
Development)
(Rev. 11891; Issued: 03-09-23; Effective: 04-21-23; Implementation: 06-19-23)
(Note that references to missing information will generally only apply to paper applications.)
A. Requirement to Furnish All Missing/Clarifying Material
The provider must furnish all missing/clarifying data/documentation the contractor requested
within the 30-day timeframe. Whether the provider furnished all information is a decision
resting solely with the contractor. Should the provider furnish some (but not all) of the requested
data/clarification within the specified time period, the contractor need not contact the provider
again to request the remaining information. For instance, suppose the contractor requested
clarification regarding data the provider furnished in Sections 3, 4, and 5 of the Form CMS-
855A. The provider only clarified the Section 3 data. The contractor may reject the application
without attempting another contact.
B. Format of Furnishing Missing/Clarifying Data
1. Paper Applications
Unless stated otherwise in this chapter or in another CMS directive, the provider shall: (1)
provide the missing/clarification information (excluding documentation) on the applicable Form
CMS-855 or CMS-20134 page(s) and (2) submit the material via mail, fax, the PCV, or scanned
e-mail. A newly signed and dated certification statement must accompany the Form CMS-855 or
CMS-20134 page(s) containing any missing data – unless the only missing information is
supporting documentation, in which case no new certification statement is needed. The provider
may submit the certification statement via scanned e-mail, fax, the PCV, or mail (paper
submissions) along with any missing information.
2. PECOS Applications
Unless stated otherwise in this chapter or in another CMS directive, the provider must furnish the
clarifying data/documentation and/or missing/clarifying documentation via PECOS. (See section
10.3 for more information.)
C. Format of Clarifying Data
(For both paper and PECOS applications, the provider must submit any missing/clarifying data
or documentation and any required new certification statement within 30 days of the original
request for clarification (rather than 30 days from the date of any follow-up request to provide
the data.))
1. Paper Applications
In cases where clarifying (as opposed to missing) information is requested, the contractor may
accept the clarification by e-mail, fax, the PCV, or letter. If the provider furnishes the
clarification via telephone, the contractor shall – unless another CMS directive states otherwise -
request that the provider furnish said clarification in writing (preferably via e-mail).
If the furnished clarification requires the provider to change or alter data that must be reported on
the paper Form CMS-855 or CMS-20134, the contractor shall instruct the provider (via a follow-up e-mail or fax) to (1) submit the revised data on the applicable paper CMS-855 or CMS-20134
or PECOS application and (2) furnish a new certification statement. The provider must submit
the certification statement via scanned PCV, e-mail, fax, or mail.
2. PECOS Applications
The provider must furnish any clarifying information or missing documentation via the PCV if
no updates to its PECOS application are needed (e.g., no documentation need be uploaded, no
changes to its Section 4 enrollment data are required). If application updates and/or
documentation are required, the contractor shall instruct the provider (via the PCV) to (1) submit
the clarified information via PECOS and (2) furnish a new certification statement in PECOS.
(Paper certification statements are not permitted.)
Consider the following illustrations:
EXAMPLE 1: The contractor notifies the provider via an e-mailed letter on March 1 of a
discrepancy regarding its ownership information on the paper Form CMS-855A. The provider e-
mails the contractor on March 3 and explains the discrepancy. Based on this e-mail, the
contractor determines that the provider must correct its ownership data in Section 5 of its Form
CMS-855A. The contractor sends a follow-up e-mail to the provider on March 7 instructing the
provider to do so. The provider must submit the revised data on the Form CMS-855 or CMS-
20134 (with a new certification statement) by March 31 (not April 6, or 30 days from the date of
the follow-up e-mail).
EXAMPLE 2: The contractor notifies the provider via a PCV-transmitted letter on March 1 of a
discrepancy regarding certain ownership information on its PECOS Form CMS-855A. The
provider telephones the contractor on March 6 and explains the discrepancy to the contractor’s
satisfaction. Although the discrepancy does not require the provider to make any revisions to its
Form CMS-855A, the contractor shall request that the provider furnish its explanation in writing
via the PCV no later than 30 days from its March 1 e-mail (or March 31), not 30 days from the
date of its March 6 request for the written explanation.
EXAMPLE 3: The contractor notifies the provider via a PCV-transmitted letter on March 1 of a
discrepancy regarding certain ownership information on its PECOS Form CMS-855A.
Determining (based on the contractor’s notification) that the ownership information it provided
was incorrect, it submits a revised Section 5 of its Form CMS-855A to the contractor with a new
certification statement via PECOS but without any accompanying explanation of the change.
The contractor receives the revised Section 5 on March 12. If the contractor determines that the
discrepancy has been resolved via the revised submission, it need not contact the provider for a
written explanation. (This is because the clarification was furnished in writing via the Form
CMS-855 or CMS-20134 itself.) If, however, the contractor would like a written explanation or
otherwise needs clarification about the submission, it may request that the provider submit a
written explanation via the PCV no later than March 31.
D. Maintenance of Received Material
Paper Applications – The contractor shall maintain all missing/clarifying information or
documentation received (including new certification statements) in PECOS via the uploading
process described in section 10.3.
PECOS Applications – The contractor shall maintain in PECOS all clarifying
information/documentation and/or missing documentation.
