Policies Related to Good Cause Reopenings for New and
Material Evidence
(Rev. 1671, Issued: 01-16-09; Effective/Implementation Date: 02-16-09)
In determining whether good cause exists for reopening an initial determination or
redetermination, the contractor considers whether evidence is new and material from the
perspective of the person or entity requesting or initiating the reopening.
When a party requests a reopening of an initial determination or redetermination for good
cause based on the submission of new and material evidence, the following policies
apply:
• The mere submission of additional evidence is not necessarily sufficient to
establish good cause to reopen an initial determination or decision. The information must
be “new,” (i.e., not readily available or known to exist at the time of the initial
determination) as well as material (i.e., may result in a different conclusion). A party
should explain how the information constitutes new and material evidence that
establishes good cause. If the contractor is unable to determine whether the information
submitted with a reopening request constitutes new and material evidence, the contractor
may decide not to grant the reopening.
• When a request for reopening is submitted with new and material evidence, but
additional information or evidence is needed before a proper revised determination or
decision can be made, the contractor may contact the party seeking the reopening, and
request that they obtain and submit the additional information. If the person or entity
requesting the reopening cannot obtain the additional information, the Medicare
contractor assists to the extent that it is reasonably able to do so.
When a Medicare contractor initiates a reopening of an initial determination or
redetermination for good cause based on the existence of new and material evidence, the
following policies apply:
• The contractor is responsible for clearly documenting in the case file the new and
material evidence that represents good cause for reopening.
• In order to promote administrative efficiency, Medicare does not generally require
that a party submit supporting medical documentation with the initial claim. Therefore, if
a medical record or other supporting documentation was not utilized when a contractor
made an initial determination, because it was not requested or was not provided, then the
content of any medical records or supporting documentation which are subsequently
requested by the contractor during the course of its review would constitute new
evidence.
