Making Sense of Medicare Part D - Drug Plan Formularies
Copyright 2006 Jeremy Cockerill
One of the most difficult portions of the new Medicare
Prescription Drug Plan to navigate is the various drug plans'
formularies. Selection of a plan is based on what drugs you are
on and which plans provide the best coverage for your selected
drugs. In order to select the optimal plan for themselves, it is
critical that Medicare-eligible individuals understand how these
formularies work.
What exactly is a formulary?
A formulary is a list of "covered" prescription drugs that the
various Medicare prescription drug plans must provide to their
enrollees. Some plans restrict prescriptions to those contained
on the formulary and others may also provide non-formulary
prescriptions depending on the level of coverage selected by the
beneficiary. Drugs contained on the formulary are generally
those that are determined to be cost effective and medically
effective. However, because of the ability of the insurance
providers to negotiate their own "deals" with the drug companies
under Medicare Part D, without having to pass the savings on to
the consumer, formularies often contain the drugs that these
insurance companies are able to negotiate the best pricing on.
Basically, the insurance providers that operate the various
plans have a Pharmacy & Therapeutics committee that chooses
which drugs they will cover on their formulary and which drugs
they will not cover. There is a national formulary coverage
standard that the insurance providers must follow when creating
their formulary under the new Medicare Prescription Drug Plan.
They must provide a certain standard level of drug coverage for
particular disease/health condition categories. This means that
these plans must cover a certain number of drugs in most disease
categories which effect seniors' health. The big mystery for
Medicare-eligible individuals to figure out is, will these plans
cover the drugs that they have been prescribed by their
physician and that they have been taking for some time.
There is one important catch with Medicare Part D that Medicare
beneficiaries must be aware of. Once a Medicare Part D
beneficiary chooses a plan they are "locked in" to that plan for
the year. Now, even though the beneficiary has done all the
research to choose the right plan that covers all of their drugs
the insurance companies have the ability to switch which drugs
are covered under their formulary (with a 60 day warning period).
Now that we know what a formulary is, the next question to ask
is "what are the "Tiers" that some of the various plans have in
their formularies?"
Most plans that have tiers will have three tiers.
Within a three-tiered formulary, prescription drug products are
categorized as Tier 1, Tier 2 or Tier 3. Each Tier is assigned a
specific co-payment amount.
What is a co-payment?
A co-payment is a cost-sharing arrangement under which a
beneficiary pays a specified dollar amount for a prescription
drug. Basically, a co-payment is a fix amount that a beneficiary
must pay for each 30-day supply of a drug they buy within a
specified Tier.
Tier 1 is the lowest co-payment level and usually contains
generic drugs.
Tier 2 is the mid-range co-payment level and usually contains
"Preferred" brand name medications.
Tier 3 is the highest co-payment level and usually contains
newer, more innovative and expensive brand name medications.
There are often specific clinical restrictions established
within a plans formulary for a beneficiary to receive these Tier
3 medications (some Tier 2 drugs may also have these
restrictions). These restrictions include Quantity Limits, Prior
Authorizations and Step Therapy.
What are Quantity Limits (QL), Prior Authorization (PA) and Step
Therapy (ST)?
Quantity Limit (QL) means that the insurance company will only
pay for a set amount of a particular drug within a given time
frame. For example, 10 tablets within a 30 day period. If you
want more than that set quantity you are responsible to pay for
the product. A good example of where a quantity limit is often
implemented is with migraine medications. Exceptions to
established quantity or days supply limits may be made if the
prescribing physician is able to justify medical necessity.
Prior Authorization is the process of obtaining coverage
approval for a particular medication. Without such prior
authorization, the medication is not covered. Authorizations are
normally issued by nurse reviewers or other authorized personnel
at the insurance company who review the doctor's orders and
other documentation to ensure that the medication is medically
necessary. A set standard or protocol is used to determine
whether the medication will be approved or not.
Step Therapy is defined as the practice of beginning drug
therapy for a medical condition with the most cost-effective and
safest drug therapy and progressing to other more costly or
risky therapy, only if necessary. The aims are to control costs
and minimize risks. Step Therapy is also called step protocol.
Step Therapy may require the beneficiary to use a "first-line"
drug before authorization is granted for a more costly
"second-line" drug. For example, an individual may be required
to try generic ibuprofen as a "first line" drug for arthritis
pain before they will be given brand name Celebrex as a "second
line" drug.
Due to the complicated formularies within many Medicare Part D
plans, it is important that participants in Medicare Part D let
their physician know which plan they have signed up for. This
way the individual's physician can work within the constraints
of the formulary in order to ensure that the beneficiary gets
the best and most appropriate therapy that is covered under
their plan.
Medicare Part D individuals should also be aware that purchasing
medications, which are not covered under their plan's formulary,
from a licensed Canadian pharmacy, is an excellent alternative
to paying the local U.S. pharmacy price. Many individuals will
also benefit greatly by ordering their medications from a
Canadian pharmacy once they have reached the gap in coverage,
called the "doughnut hole". This gap in coverage occurs at the
$2250 annual drug expenditure level and beneficiaries are 100%
responsible for their drug costs until they reach $5100 in drug
expenditures. For a surprisingly high number of individuals,
they may save more by ordering all of their medications from
Canada rather than purchasing them through the Medicare program.
Medicare Part D beneficiaries must understand how their plan's
formulary works and they also need to keep up to date with any
notices of changes to their plan's formulary. Without keeping up
to date they may find themselves in a position in which they are
unable to get their medication the next time they walk into
their pharmacy. With the preceding information a Medicare
beneficiary will be better equipped to choose a plan that is
best for them. Medicare Part D coverage combined with Canadian
pharmacy savings can provide seniors with incredible savings.
These individuals should be able to save a lot of money.
