CMS Pub. 100-04, ch. 27, § 60.1
Requesting to Pay Claims Outside of CWF
A/B MACs or DME MACs may also request approval from CMS in specific situations to
pay claims without CWF approval. Examples of such situations are:
• Other A/B MACs or DME MACs cannot complete action to remove an
impediment that blocks a contractor from processing of a claim; and/or
• A systems error cannot be corrected timely, and the provider's cash flow will be
seriously endangered.
• Administrative Law Judge (ALJ) decisions, court decisions, and CMS instructions
in particular cases may necessitate that payment be made outside the normal CWF
process.
A/B MACs or DME MACs shall obtain approval from CMS to pay a claim without CWF
approval prior to processing that claim outside the CWF/CWF system. A/B MACs and
DME MACs shall submit a written request to their CMS Contracting Officer
Representative (COR) for approval to make payment without CWF approval. Such
requests shall be submitted by facsimile transmission or via the Internet. To ensure the
protection of the Personal Health Information (PHI) and Personally Identifiable
Information (PII) contained in contractor requests to pay claims without CWF approval,
contractors shall encrypt their E-mail submitted requests.
A/B MACs or DME MACs shall provide the following information to their CMS COR
when requesting to pay a claim without CWF approval:
a) A/B MAC or DME MAC’s Internal Claim Control Number,
b) Medicare beneficiary identifier,
c) Beneficiary Name,
d) Provider Number (National Provider Identification (NPI) Number),
e) From and To Date of Service,
f) Procedure Code(s),
g) Total Charges,
h) Amount to be Paid,
i) CWF Error Code/Condition Preventing Payment (including error code definition),
and
j) Rationale for Paying the Claim Outside the CWF/CWF System.
