Title: Managed Care ppt
1 2Overview
- Health Insurance tends to lead to an
overconsumption of healthcare by the insured
because the insured person only considers
out-of-pocket expenses and not the full cost at
point of purchase. - i.e., purchases of healthcare beyond the point
where marginal benefit equals marginal cost - Can also have overprovision of healthcare
services because of SID and SAV. - Response to overconsumption or overprovision set
up a system where physician practice must be
managed in order to address high healthcare costs
and the overprovision of services.

4WHAT IS THE ORGANIZATIONAL STRUCTURE?Managed
Care Organizations Defined
- Analysts speak of an organized delivery system as
a network of organizations (for example,
hospitals, physicians, clinics, and hospices)
that provides or arranges to provide a
coordinated continuum (from well care to
emergency surgery) of services to a defined
population.
5Managed Care Organizations Defined
- This system is held clinically and fiscally
accountable for the outcomes and the health
status of the population served. It is tied
together by its clinical (treatment) and fiscal
(financial) accountability for the defined
population. - This means that there could be financial
penalties on physicians that have higher volumes
of services - Often the organized delivery system is defined by
its association with an insurance product.
6What can a MCO do?
- Can contain costs and perhaps improve the quality
of care by using three mechanisms - Selective contracting payer negotiate prices
with selected physicians and hospitals - Steering send enrollees to providers in the
network - Utilization Review review appropriateness of
provider practices, in a few different ways - Well discuss the first two in a little more
detail later, but first well consider
utilization review
7Utilization Review
- Examines the appropriateness of medical care for
necessity and appropriateness before, during and
after medical care - Prospective (before care) e.g., require
mandatory second opinions and pre-admission
certification to determine whether surgery and
length of hospital stay that are appropriate - Concurrent (during care) occurs during
hospitalization and determines the
appropriateness of treatment relative to
diagnosis and discharge planning
8- Retrospective (after treatment) reviews
treatment after discharge to determine whether
treatment was necessary and appropriate and
whether they were actually provided can also be
used to determine practice patterns which
identify providers and facilities that are
providing treatment in a cost-effective manner
and those that are not.
9- Differences between managed care and
fee-for-service arrangements have to be measured
along several dimensions, which would include
health of people receiving treatment price of
care and, quality of care. - Common characteristics of managed care are that
most (if not all) care for a patient is provided
in a network and resources are centralized in the
network (via utilization review).
10WHAT ARE THE ECONOMIC CHARACTERISTICS?Overview
- Managed care features a health care delivery
structure involving the integration of insurers,
payment mechanisms, and a host of providers,
including physicians and hospitals. - There are three different types of managed care
organizations that we will consider.
11Table 12-1 Summary of Different Health System
Organizational Structures
12Health Maintenance Organizations (HMOs)
- Provide relatively comprehensive health care,
entail few out-of-pocket expenses, but generally
require that all care be delivered through the
plans network and that the primary care
physician authorize any services provided.
13Preferred Provider Organizations (PPOs)
- Provides two distinct tiers of coverage. When
subscribers use the PPOs preferred provider
network, the required cost sharing with
deductibles or coinsurance is lower than when
they use nonnetwork providers. Although a network
is formed, PPOs have no physician gatekeepers.
14Point of Service (POS) Plans
- Are a hybrid of HMOs and PPOs. Like PPOs, POS
plans offer two tiers of insurance benefits.
Coverage is greater (out-of-pocket costs are
lower) when members use network providers and
less generous (out-of-pocket costs are higher)
when they use nonnetwork providers. Like HMOs,
however, POS plans assign each member a physician
gatekeeper, who must authorize in-network care in
order for the care to be covered on in-network
terms.
15Managed Care Contracts with Physicians
- Most HMO and POS plans pay their network
physicians on a capitation basis. - Under capitation, the plan pays the physicians
practice a fixed fee, generally an actuarial
per-member-per-month (PMPM) dollar amount, in
return for the treatments provided to members of
the insurance plan.
16Managed Care Contracts with Physicians - continued
- PPO contracts with physicians rarely involve
capitation. Instead, they specify the discounted
fees for various services that the plan will pay
in exchange for the privilege of being in that
plans network. - Utilization review procedures are commonly
covered in managed care contracts, whether they
are HMO, PPO, or POS plans.
17Managed Care Contracts with Hospitals
- HMO and PPO plans contract with only a subset of
the providers (physicians and hospitals) in the
areas that they serve. This key feature of the
managed care sector allows plans to promote price
competition among hospitals that might otherwise
lose plan business.
18Managed Care Contracts with Hospitals - continued
- The probability and characteristics of contracts
between individual managed care organizations and
hospitals appear to depend on three sets of
factors - Plan characteristics, including whether it was a
PPO or an HMO (and possibly what type of HMO),
plan size, whether the plan serves several
localities, and how old the plan is. - Hospital characteristics, including size,
ownership (including for-profit versus nonprofit
status), location (city versus suburb), teaching
status, and cost structure (reflecting prices). - Market characteristics, generally measured at the
metropolitan area level, including the
penetration and rate of growth of managed care
plans.
19Managed Care Contracts with Hospitals - continued
- Zwanziger and Meirowitz (1998) examine the
determinants of plan contracts with hospitals in
a study that looks at the three categories. For
HMOs and PPOs in 13 large, metropolitan
statistical areas (MSAs), they report - Managed care plans prefer to contract with
nonprofit hospitals, preferring even public
hospitals to for-profit ones. - Plans will more likely contract with large
hospitals compared with medium-sized hospitals,
and with medium-sized hospitals compared with
small ones. - Hospital cost factors (which reflect hospital
prices) do not significantly affect contracts.
20Economic Implications of Managed Care
- There are a few economic different aspects of
managed care that we will consider. This will be
from the perspective of the U.S. health care
system, but some contrasts to Canada will also
appear (and be discussed later in the course). - There are two potential benefits of managed care
- Reducing price discrimination
- Reducing prices
211. Price Discrimination
- If you have perfect competition (suppose MCAC,
so supply curve is horizontal) then health care
providers are price takers. - This is a very appropriate description of how the
health care markets work in Canada. - However, in the U.S. not all physicians are price
takers. In fact, some (or many) can viewed as
having some sort of monopoly power, they can
charge different prices to different consumers,
which is referred to as price discrimination
22- To price discriminate you need two basic
conditions to hold - You need to be able to distinguish between
different consumers and hence their demand curves - You need to be able to prevent the resale of
goods from one type of consumer to another type
of consumer
23 - For example, socioeconomic status is known to
tell you a lot about the demand for health care
services - Persons with higher socioeconomic status tend to
have more inelastic demand for health care
services - If a physician has monopoly power and is able to
distinguish between different segments of the
market and there is no resale between markets can
treat markets separately
24In market with elastic demand
25In market with inelastic demand
26Implications of Price Descrimination
- In the market with the more inelastic demand the
price is higher than in the market with the more
elastic demand curve so the more inelastic
demand is the higher the price for medical
services
- In the limit, if the physician could distinguish
between all the different demand curves there
would be perfect price discrimination, so every
consumer pays a different price.
27- Price discrimination means that the physician
will extract more of the consumer surplus than if
the physician did not price discriminate. - Perfect price discrimination means that the
physician will extract all the consumer surplus.
282. Lowering Prices
- It can also reduce the demand for care by
reducing the potential for SID as well as SAV
- For a consumer, managed care can reduce the price
paid for services, i.e, the MC of services will
be lower
29Managed Care vs fee-for service
30Why?
- Changed incentives in managed care should
constrain utilization/provision of services and
the prices for services. - Incentives mean the healthcare provider shares
risks with the insurer and so reduces the volume
of services they can provide
