9.4 Cost Containment and Provider Arrangements

How Managed Care Controls Cost

Managed care plans deploy specific cost-containment techniques. The national exam asks you to identify each technique by its definition. They fall into two groups: utilization controls (managing what care is delivered) and provider reimbursement arrangements (managing how providers are paid).

Utilization Management Techniques

Trap: Precertification is done BEFORE treatment; concurrent review happens DURING a stay; retrospective review occurs AFTER care. The exam tests the timing of each.

Provider Reimbursement Arrangements

How a plan pays providers shapes the incentives in the system.

• Capitation - the provider receives a fixed amount per member per month (PMPM) regardless of services used. Common in HMOs; shifts financial risk to the provider and rewards prevention.
• Fee-for-service (UCR) - the provider bills per service, paid up to a Usual, Customary, and Reasonable amount. Common in indemnity and PPO plans; can encourage more services.
• Discounted fee schedule - PPOs negotiate reduced fees in exchange for patient volume.
• Salaried providers - staff-model HMOs employ physicians directly.

Worked Numeric: Capitation vs. Fee-for-Service

An HMO pays a clinic $40 PMPM for 1,000 members. A member with chronic illness uses $9,000 of care that year.

Capitation revenue: 1,000 x $40 x 12 = $480,000 (fixed)
The clinic bears the $9,000 cost regardless.
Incentive: keep members healthy to control utilization.

Under fee-for-service, the clinic would instead bill UCR for each visit, so the insurer's cost rises with utilization.

Coordination of Benefits (COB)

When a person is covered by two group plans, COB prevents the insured from collecting more than 100% of the loss. One plan is primary (pays first to its full benefit) and the other is secondary (pays the remaining eligible expense up to its limits).

The Birthday Rule

For a child covered under both parents' plans, the plan of the parent whose birthday falls earlier in the calendar year (month and day, not the older parent) is primary.

Worked Numeric: COB

A $1,000 covered claim. Plan A (primary) pays 80% after no deductible; Plan B (secondary) covers 100%.

Plan A primary pays:    80% x $1,000 = $800
Remaining expense:      $200
Plan B secondary pays:  up to $200
Insured out-of-pocket:  $0
Total paid by plans:    $1,000 (never more than the loss)

Other Cost Controls

• Mandatory generic substitution and tiered drug formularies lower pharmacy cost.
• Preventive care incentives reduce expensive late-stage treatment.
• Disease management programs target chronic conditions.

Timing of Utilization Reviews

Because the exam loves the timing distinctions, lock them in:

A missed precertification can reduce or deny a benefit even for otherwise covered care, so producers warn clients to obtain prior authorization for scheduled procedures and non-emergency hospital admissions.

UCR and Reasonable Charges

Under a Usual, Customary, and Reasonable standard, the insurer pays a fee up to what is normal for that procedure in that geographic area. If a provider charges above UCR on an indemnity plan, the insured pays the excess. PPOs avoid this by contracting fixed discounted fees, so in-network PPO members are not balance billed above the negotiated rate.

COB Order of Determination

Beyond the birthday rule, COB rules set which plan pays first:

• A plan covering a person as an employee is primary over one covering them as a dependent.
• For a child of divorced parents, a court decree controls; otherwise the custodial parent's plan is primary.
• Active employee coverage is primary over retiree or COBRA continuation coverage.

Worked Numeric: COB with a Deductible

A $2,000 covered claim. Plan A (primary) has a $500 deductible then pays 80%. Plan B (secondary) covers 100% of allowed expense.

Plan A: deductible $500, then 80% of $1,500 = $1,200 paid
Plan A insured share so far:  $800
Plan B secondary pays:        up to $800
Insured out-of-pocket:        $0
Total paid by plans:          $2,000 (never exceeds the loss)

COB's anti-duplication purpose is why a person with two plans cannot profit from a single medical expense - a recurring exam theme.

Provider Networks and Steerage

Cost containment also works through steerage - financial incentives that push members toward efficient, in-network providers. Tiered networks, reference pricing (a fixed allowance for shoppable procedures), and centers-of-excellence designations all steer volume to lower-cost, higher-quality providers. The exam frames these as managed-care techniques that lower aggregate spending without denying care outright.

Quality Controls Alongside Cost

Managed care is not only about cost; it pairs spending controls with quality assurance. Plans use credentialing of providers, outcome measurement, and accreditation (e.g., NCQA) to ensure that utilization controls do not compromise care. The exam may test that managed care seeks both lower cost and maintained or improved quality - the two goals are presented together, not in opposition.
