Health
insurance
The term health
insurance is
generally used to
describe a form of
insurance that pays
for medical
expenses. It is
sometimes used more
broadly to include
insurance covering
disability or
long-term nursing or
custodial care
needs. It may be
provided through a
government-sponsored
social insurance
program, or from
private insurance
companies. It may be
purchased on a group
basis (e.g., by a
firm to cover its
employees) or
purchased by
individual
consumers. In each
case, the covered
groups or
individuals pay
premiums or taxes to
help protect
themselves from high
or unexpected
healthcare expenses.
Similar benefits
paying for medical
expenses may also be
provided through
social welfare
programs funded by
the government.
Health insurance
works by estimating
the overall risk of
healthcare expenses
and developing a
routine finance
structure (such as a
monthly premium or
annual tax) that
will ensure that
money is available
to pay for the
healthcare benefits
specified in the
insurance agreement.
The benefit is
administered by a
central
organization, most
often either a
government agency or
a private or
not-for-profit
entity operating a
health plan.
A Health insurance
policy is a contract
between an insurance
company and an
individual. The
contract can be
renewable annually
or monthly. The type
and amount of health
care costs that will
be covered by the
health plan are
specified in
advance, in the
member contract or
Evidence of Coverage
booklet. The
individual
policy-holder's
payment obligations
may take several
forms
|
*
Premium:
The amount the
policy-holder
pays to the
health plan each
month to
purchase health
coverage.
* Deductible:
The amount that
the
policy-holder
must pay
out-of-pocket
before the
health plan pays
its share. For
example, a
policy-holder
might have to
pay a $500
deductible per
year, before any
of their health
care is covered
by the health
plan. It may
take several
doctor's visits
or prescription
refills before
the
policy-holder
reaches the
deductible and
the health plan
starts to pay
for care.
*
Copayment:
The amount that
the
policy-holder
must pay out of
pocket before
the health plan
pays for a
particular visit
or service. For
example, a
policy-holder
might pay a $45
copayment for a
doctor's visit,
or to obtain a
prescription. A
copayment must
be paid each
time a
particular
service is
obtained.
*
Coinsurance:
Instead of
paying a fixed
amount up front
(a copayment),
the
policy-holder
must pay a
percentage of
the total cost.
For example, the
member might
have to pay 20%
of the cost of a
surgery, while
the health plan
pays the other
80%. Because
there is no
upper limit on
coinsurance, the
policy-holder
can end up owing
very little, or
a significant
amount,
depending on the
actual costs of
the services
they obtain.
* Exclusions:
Not all services
are covered. The
policy-holder is
generally
expected to pay
the full cost of
non-covered
services out of
their own
pocket.
*
Coverage limits:
Some health
plans only pay
for health care
up to a certain
dollar amount.
The
policy-holder
may be expected
to pay any
charges in
excess of the
health plan's
maximum payment
for a specific
service. In
addition, some
plans have
annual or
lifetime
coverage
maximums. In
these cases, the
health plan will
stop payment
when they reach
the benefit
maximum, and the
policy-holder
must pay all
remaining costs.
*
Out-of-pocket
maximums:
Similar to
coverage limits,
except that in
this case, the
member's payment
obligation ends
when they reach
the
out-of-pocket
maximum, and the
health plan pays
all further
covered costs.
Out-of-pocket
maximums can be
limited to a
specific benefit
category (such
as prescription
drugs) or can
apply to all
coverage
provided during
a specific
benefit year.

*
Capitation:
An amount paid by an
insurer to a health
care provider, for
which the provider
agrees to treat all
members of the
insurer.
*
In-Network Provider:
A health care
provider on a list
of providers
preselected by the
insurer. The insurer
will offer
discounted
coinsurance or
copayments, or
additional benefits,
to a plan member to
see an in-network
provider. Generally,
providers in network
are providers who
have a contract with
the insurer to
accept rates further
discounted from the
"usual and
customary" charges
the insurer pays to
out-of-network
providers.
Prescription drug
plans are a form of
insurance offered
through some
employer benefit
plans in the US,
where the patient
pays a copayment and
the prescription
drug insurance part
or all of the
balance for drugs
covered in the
formulary of the
plan.
Some, if not most,
health care
providers in the
United States will
agree to bill the
insurance company if
patients are willing
to sign an agreement
that they will be
responsible for the
amount that the
insurance company
doesn't pay. The
insurance company
pays out of network
providers according
to "reasonable and
customary" charges,
which may be less
than the provider's
usual fee. The
provider may also
have a separate
contract with the
insurer to accept
what amounts to a
discounted rate or
capitation to the
provider's standard
charges. It
generally costs the
patient less to use
an in-network
provider.
Health plan vs.
health insurance
Historically, HMOs
tended to use the
term "health plan",
while commercial
insurance companies
used the term
"health insurance".
A health plan can
also refer to a
subscription-based
medical care
arrangement offered
through health
maintenance
organization, HMO,
PPO, or POS plan.
These plans are
similar to pre-paid
dental, pre-paid
legal, and pre-paid
vision plans.
Pre-paid health
plans typically pay
for a fixed number
of services (for
instance, $300 in
preventive care, a
certain number of
days of hospice care
or care in a skilled
nursing facility, a
fixed number of home
health visits, a
fixed number of
spinal manipulation
charges, etc.) The
services offered are
usually at the
discretion of a
utilization review
nurse who is often
contracted through
the managed care
entity providing the
subscription health
plan. This
determination may be
made either prior to
or after hospital
admission
(concurrent
utilization review).
Comprehensive vs.
scheduled
Comprehensive health
insurance pays a
percentage (may be
100, 90, 80, 70, 60,
50, percent) of the
cost of hospital and
physician charges
after a deductible
(usually applies to
hospital charges) or
a co-pay (usually
applies to physician
charges, but may
apply to some
hospital services)
is met by the
insured. These plans
are generally
expensive because of
the high potential
benefit payout —
$1,000,000 to
5,000,000 is common
— and because of the
vast array of
covered benefits.
Scheduled health
insurance plans are
not meant to replace
a traditional
comprehensive health
insurance plans and
are more of a basic
policy providing
access to day-to-day
health care such as
going to the doctor
or getting a
prescription drug.
In recent years,
these plans have
taken the name
mini-med plans or
association plans.
These plans may
provide benefits for
hospitalization and
surgical, but these
benefits will be
limited. Scheduled
plans are not meant
to be effective for
catastrophic events.
These plans cost
much less then
comprehensive health
insurance. They
generally pay
limited benefits
amounts directly to
the service
provider, and
payments are based
upon the plan's
"schedule of
benefits". Annual
benefits maximums
for a typical
scheduled health
insurance plan may
range from $1,000 to
$25,000.
Inherent problems
with insurance
Insurance systems
must typically deal
with two inherent
challenges: adverse
selection, which
affects any
voluntary system,
and ex-post moral
hazard, which
affects any
insurance system in
which a third party
bears major
responsibility for
payment, whether
that is an employer
or the government.
Some national
systems with
compulsory insurance
utilize systems such
as risk equalization
and community rating
to overcome these
inherent problems.
Adverse selection
Insurance companies
use the term
"adverse selection"
to describe the
tendency for only
those who will
benefit from
insurance to buy it.
Specifically when
talking about health
insurance, unhealthy
people are more
likely to purchase
health insurance
because they
anticipate large
medical bills. On
the other side,
people who consider
themselves to be
reasonably healthy
may decide that
medical insurance is
an unnecessary
expense; if they see
the doctor once a
year and it costs
$250, that's much
better than making
monthly insurance
payments of $40.
The fundamental
concept of insurance
is that it balances
costs across a
large, random sample
of individuals (see
risk pool). For
instance, an
insurance company
has a pool of 1000
randomly selected
subscribers, each
paying $100 per
month. One person
becomes very ill
while the others
stay healthy,
allowing the
insurance company to
use the money paid
by the healthy
people to pay for
the treatment costs
of the sick person.
However, when the
pool is
self-selecting
rather than random,
as is the case with
individuals seeking
to purchase health
insurance directly,
adverse selection is
a greater
concern.[10] A
disproportionate
share of health care
spending is
attributable to
individuals with
high health care
costs. In the US the
1% of the population
with the highest
spending accounted
for 27% of aggregate
health care spending
in 1996. The
highest-spending 5%
of the population
accounted for more
than half of all
spending. These
patterns were stable
through the 1970s
and 1980s, and some
data suggest that
they may have been
typical of the
mid-to-early 20th
century as well. A
few individuals have
extremely high
medical expenses, in
extreme cases
totaling a half
million dollars or
more. Adverse
selection could
leave an insurance
company with
primarily sick
subscribers and no
way to balance out
the cost of their
medical expenses
with a large number
of healthy
subscribers.
Because of adverse
selection, insurance
companies employ
medical
underwriting, using
a patient's medical
history to screen
out those whose
pre-existing medical
conditions pose too
great a risk for the
risk pool. Before
buying health
insurance, a person
typically fills out
a comprehensive
medical history form
that asks whether
the person smokes,
how much the person
weighs, whether the
person has been
treated for any of a
long list of
diseases and so on.
In general, those
who present large
financial burdens
are denied coverage
or charged high
premiums to
compensate.[14] One
large US industry
survey found that
roughly 13 percent
of applicants for
comprehensive,
individually
purchased health
insurance who went
through the medical
underwriting in 2004
were denied
coverage.
Declination rates
increased
significantly with
age, rising from 5
percent for
individuals 18 and
under to just under
a third for
individuals aged 60
to 64.Among those
who were offered
coverage, the study
found that 76%
received offers at
standard premium
rates, and 22% were
offered higher
rates. On the other
side, applicants can
get discounts if
they do not smoke
and are healthy.
