CMS Pub. 100-04, ch. 30, § 260.4.5
The Detailed Explanation of Non-Coverage
The DENC is subject to the Paperwork Reduction Act Process and approval by the Office
of Management and Budget. OMB-approved notices may only be modified as per their
accompanying instructions. Unapproved modifications may invalidate the DENC. The
notice and accompanying instructions may be found online at
http://www.cms.gov/Medicare/Medicare-General-Information/BNI. Medicare providers
are responsible for the delivery of the DENC to beneficiaries who request an expedited
determination by the QIO.
The DENC must contain the following information:
• The facts specific to the beneficiary’s discharge and provider’s determination that
coverage should end.
• A specific and detailed explanation of why services are either no longer
reasonable and necessary or no longer covered.
• A description of, and citations to, the Medicare coverage rule, instruction, or other
policies applicable to the review.
The provider should make insertions on the notice in Spanish, if necessary. If this is
impossible, additional steps should be taken to ensure that the beneficiary comprehends
the content of the notice. Providers may resource CMS multilingual services provided
through the 1-800-MEDICARE help line if needed.
The delivery must occur in person by close of business of the day the QIO notifies the
provider that the beneficiary has requested an expedited determination. A provider may
also choose to deliver the DENC with the NOMNC.
The DENC does not require a signature but should be annotated in the event of a
beneficiary’s refusal to accept the notice upon delivery.
Note: An HHA is not required to make a separate trip to the beneficiary’s residence
solely to deliver a DENC. Upon notification from the QIO of a beneficiary’s request for
an expedited determination, an HHA may telephone the beneficiary to provide the
information contained on the DENC, annotate the DENC with the date and time of
telephone contact and file with the beneficiary’s records. A hard copy of the DENC
should be sent to the beneficiary via tracked mail or other personal courier method by
close of business of the day the QIO notifies the provider that the beneficiary has
requested an expedited determination. The burden is on the provider to demonstrate that
timely contact was attempted with the beneficiary and that the notice was delivered.
DENC delivery to representatives, DENC hours of delivery, and DENC retention
requirements are the same as the NOMNC requirements outlined in §260.3.

decision and notifies
Bob and the SNF by
COB.
If Bob made his
request on
