Prescription Drug Coverage
10.4 - Prescription Drug Coverage
(Rev. 77, Issued: 10-28-05, Effective Date: 10-28-05)
(70 FR 4243, Jan 28, 2005) A Medicare cost plan offering a cost plan may, but is not
required to, offer prescription drug coverage. There are three methods of offering
prescription drug coverage in a cost plan:
1) No Offering of a Part D Plan
The Medicare cost plan may elect not to offer qualified Part D coverage. In such
a case the Medicare cost plan may offer non-qualified prescription drug coverage
as an optional supplemental benefit. This non-qualified prescription drug
coverage may be, but is not required to be, creditable, as defined in 42 CFR
423.56. Enrollees of a cost plan not offering qualified Part D coverage may elect
to concurrently enroll in a Prescription Drug Plan (PDP).
2) Offering of Basic, Part D Coverage
An organization may elect to offer a Medicare cost plan that provides basic part
D coverage. If the organization so elects, then this Part D coverage must be
offered as an optional supplemental benefit; that is, an enrollee has the option,
but not the obligation, to purchase Part D coverage under the plan. All enrollees
who purchase the Part D coverage offered by the Medicare cost plan must
receive coverage of Part A and Part B, [or Part B only (for beneficiaries who are
not entitled to Part A)] benefits under that cost plan. If the enrollee elects not to
elect the Part D coverage offered by the Medicare cost plan, then such an
enrollee may concurrently enroll in a Prescription Drug Plan (PDP). A
Medicare cost plan offering qualified Part D coverage, may not offer non-
qualified prescription drug coverage. (See 42 CFR 423.104(f)(4).)
3) Offering of Both Basic and Enhanced Alternative Part D Coverage
The Medicare cost plan may elect to offer both basic and enhanced alternative
Part D coverage as optional supplemental benefits. An enrollee may then elect to
either: (a) Purchase the basic Part D coverage; (b) Purchase the enhanced
alternative Part D coverage; or (c) To purchase neither. If the enrollee elects not
to elect part D coverage through the cost plan, the enrollee retains his/her right
to concurrently enroll in another Prescription Drug Plan (PDP). A Medicare
cost plan offering qualified Part D coverage, may not offer non-qualified
prescription drug coverage. (See 42 CFR 423.104(f)(4).)
If a Medicare cost plan offers qualified Part D coverage then the funding for the
Part D coverage is separate from the CMS funding for Part A and/or B coverage
(42 CFR 417.534(c)). Consequently, a Medicare cost plan may not apply
reductions or non-collection of deductibles and coinsurance for Part A and/or B
services to subsidize Part D coverage.

group health plan.
