CMS Pub. 100-18, ch. 6, § 30.4.10
Transition Notices
A successful transition process is contingent upon informing enrollees and their health care
provider about their options for ensuring that enrollees’ medical needs are safely accommodated
within a Part D sponsor’s formulary. An enrollee who receives a temporary supply of a non-formulary Part D drug at a network pharmacy might simply assume that, by virtue of filling his
or her prescription, that the plan will cover that drug for the remainder of the contract year. For
this reason, sponsors must provide enrollees with appropriate notice regarding their transition
process within a reasonable amount of time after providing a temporary supply of non-formulary
Part D drugs (including Part D drugs that are on a sponsor’s formulary but require prior
authorization or step therapy under a sponsor’s utilization management rules).
Part D sponsors will be required to send a written notice, via U.S. First Class mail, to each
enrollee who receives a transition fill. This standard is consistent with CMS’ requirement that
other beneficiary communications, including formulary change notices and explanations of
benefits, be sent via U.S. First Class mail. In addition, this notice must be sent to each affected
enrollee within 3 business days of adjudication of the temporary transition fill. If the enrollee
completes his or her transition supply in several fills, the sponsor is required to send notice with
the first transition fill only. CMS believes this turnaround is necessary in order to provide an
affected enrollee with sufficient time -- especially in light of CMS’ 30-day transition fill policy
in the retail setting -- to work with his or her prescriber to switch to a therapeutically equivalent
drug that is on the plan’s formulary or to process an exceptions request.
The notice must include the following elements:
• That the transition supply provided is temporary;
• That the enrollee should work with the sponsor as well as his or her health care provider
to satisfy utilization management requirements or to identify appropriate therapeutic
alternatives that are on the sponsor’s formulary;
• That the member has the right to request a formulary exception, the timeframes for
processing the exception, and the member's right to request an appeal if the sponsor
issues an unfavorable decision; and
• The sponsor’s procedures for requesting a formulary exception.
CMS provides Part D sponsors with a model transition letter. CMS expects that sponsors will
make prior authorization or exception request forms available upon request to both enrollees and
prescribing physicians and via a variety of mechanisms -- including by mail, fax, email, and on
sponsor Web sites. To the extent that sponsors have the capacity, CMS encourages them to
provide any prior authorization or exception request forms a beneficiary will need to effectuate a
transition with the transition notice.
CMS strongly encourages point-of-sale notification to enrollees about transition supplies by
pharmacists. CMS has worked with the pharmacy and drug benefit industry, including the
National Council for Prescription Drug Programs (NCPDP), to incorporate a work-around
process for using structured payment coding in the message field of billing transaction responses
indicating that a particular fill is a transition supply. This process is consistent with the current
NCPDP standard. For more information about Standardized Claims Messaging see chapter 14,
section 50.5.
