indicating that beneficiaries should have a more advantageous cost-sharing than
indicated by CMS data. Sponsors are responsible for notifying members when
they become LIS eligible, when their LIS levels change, and when their LIS
eligibility terminates. Since LIS changes are frequently effective retroactively,
sponsors must establish procedures to reimburse current and former members for
cost-sharing (including deductible and copayments) and premiums paid before
notification of LIS eligibility. The following subsections describe these
requirements in detail, as well as the LIS notification requirements that are the
responsibility of the Part D sponsor.
70.1 - Establishing Low-Income Subsidy Status
(Rev. 13, Issued: 07-29-11, Effective Date: 01-01-11; Implementation
Date: 01-01-11)
In order to establish the correct premium, cost sharing and deductible levels with
the correct effective dates for current, prior, and prospective enrollees, Part D
sponsors should refer to the Weekly/Monthly Transaction Reply Report (TRR).
Part D sponsors will receive data indicating new or modified LIS eligibility status
for former, current, and prospective members of their Part D plan via the weekly
TRR. Full replacement LIS profiles are represented by an ensemble composed of
one or more of TRCs 121, 194, and 223. Each profile returns LIS period start and
end dates, premium subsidy percentage, co-payment level, enrollee type flag, and
LIS source code. The enrollee type flag identifies a beneficiary as being a prior,
current, or prospective enrollee. The LIS source code identifies whether the LIS
period is the result of CMS deeming or SSA approval.
In addition, twice each year, CMS issues special files related to Part D sponsors’
LIS members. These are the September and December versions of the Loss of
Subsidy file. The September file informs sponsors who in their plan is getting
CMS’ “undeemed” letter, and is to be used for outreach purposes. However, the
December file is the definitive file of those losing LIS status, and is to be used to
update sponsors’ systems and to identify to whom they should send the LIS
termination notice. CMS will send guidance notifying Part D Sponsors of the
specific dates of these special files and reminding them of their purpose. For more
information on these files’ purpose, see section 40.2.6; for additional details and
technical specifications, see the appendices of the Plan Communications User
Guide (PCUG)

of Subsidy Data File (F30).
70.2 - Member Notifications
(Rev. 14, Issued: 10-01-18, Effective Date: 10-01-18; Implementation Date: 10-01-18)
Part D sponsors are required to notify members when they initially become LIS-
eligible; when their LIS levels change; and when their LIS eligibility terminates.
In addition, certain notifications are required pursuant to the BAE policy (see
section 70.5). The descriptions below explain the different LIS notifications,
when Part D sponsors must mail these notifications to their member beneficiaries
