9.4 Cost Containment and Provider Arrangements
Key Takeaways
- Utilization review is timed: prospective (before, preauthorization), concurrent (during a stay), retrospective (after, claims review).
- Capitation pays providers a fixed per-member-per-month amount, shifting utilization risk to the provider and rewarding prevention.
- Fee-for-service pays per service and can encourage overutilization; UCR caps payment to area-prevailing charges.
- Out-of-network providers may balance bill above UCR; in-network providers agree not to, which contains insured cost.
- Second surgical opinions, case management, formularies, and disease management are additional cost-containment tools.
How Managed Care Controls Cost
Beyond network discounts, managed care plans deploy cost-containment mechanisms that the exam tests by name and timing. The two anchor concepts are utilization review and provider reimbursement arrangements.
Utilization Review — Timing Matters
Utilization review (UR) evaluates the medical necessity, appropriateness, and efficiency of services. It comes in three forms defined by when they occur relative to treatment:
| Type | When | Purpose |
|---|---|---|
| Prospective | Before treatment | Preauthorization / prior authorization for admissions, surgeries, costly tests |
| Concurrent | During treatment | Monitors ongoing hospital stays; certifies continued necessity |
| Retrospective | After treatment | Reviews claims after the fact for necessity and billing accuracy |
Exam trap: Prospective = before (preauthorization). Concurrent = during (the patient is currently admitted). Retrospective = after (claims review). A question describing "preauthorization for a scheduled surgery" is prospective review.
Other Cost-Containment Tools
- Second surgical opinion (SSO): plan covers (or requires) a second opinion before elective surgery to avoid unnecessary procedures.
- Case management: a coordinator manages complex, high-cost cases to steer care efficiently.
- Gatekeeper (PCP) model: the HMO/POS requirement that the PCP authorize specialist care.
- Preventive care emphasis: covering wellness visits and screenings at low or no cost to head off costly claims.
- Disease management programs: structured support for chronic conditions (diabetes, asthma) to reduce hospitalizations.
- Prescription formularies: tiered drug lists steering members toward lower-cost generics.
Provider Reimbursement Arrangements
How the plan pays providers is a core cost lever and a frequent exam item.
| Arrangement | How the provider is paid | Incentive created |
|---|---|---|
| Fee-for-service (FFS) | Per service rendered | Rewards volume of services |
| Capitation | Fixed amount per member per month (PMPM) regardless of services used | Rewards efficiency; provider bears utilization risk |
| Salary | Fixed salary (staff-model HMO physicians) | Neutral on volume |
| UCR / negotiated fee | Reasonable & customary or contracted discounted rate | Caps payment to area norms |
Capitation is central to HMOs: the provider receives a set per-member-per-month payment and must deliver needed care within it, shifting utilization risk to the provider and rewarding prevention. Contrast with traditional fee-for-service, which pays per service and can encourage overutilization.
Capitation Worked Example
A medical group is paid $40 PMPM (per member per month) for 500 enrolled members.
Monthly capitation: 500 members × $40 = $20,000
Annual capitation: $20,000 × 12 = $240,000
The group receives $240,000 per year whether members make zero visits or many — it profits by keeping members healthy and controlling utilization, and absorbs the loss if costs exceed the cap.
UCR and Out-of-Network Balance Billing
In fee-for-service and PPO out-of-network situations, the plan pays up to a Usual, Customary, and Reasonable (UCR) amount — the prevailing charge for that service in that geographic area. If a provider bills above UCR, the insured may face balance billing (the difference between the charge and the allowed UCR amount). In-network providers agree not to balance bill.
UCR Worked Example
A surgeon charges $8,000; the plan's UCR for the procedure is $6,000 with 80/20 coinsurance.
UCR allowed amount: $6,000
Plan pays 80%: $4,800
Insured coinsurance: $1,200 (20% of $6,000)
Balance bill (above UCR): $2,000
Total insured (out-of-network): $1,200 + $2,000 = $3,200
The insured owes $3,200 out-of-network versus only $1,200 if the surgeon were in-network and could not balance bill — illustrating why network arrangements contain cost.
A managed care plan requires preauthorization before a member can undergo a scheduled non-emergency surgery. Which type of utilization review is this?
An out-of-network surgeon charges $10,000; the plan's UCR allowance is $7,000 with 80/20 coinsurance and no in-network balance-billing protection. Ignoring the deductible, how much does the insured pay in total?
Capitation vs. Fee-for-Service Incentives
The reimbursement method shapes provider behavior, and the exam tests the incentive each creates. Under capitation, a provider receives a fixed per-member-per-month payment regardless of services rendered, which rewards prevention and cost control (and risks under-treatment). Under fee-for-service, the provider is paid per service, which can encourage over-utilization.
| Arrangement | Payment basis | Built-in incentive |
|---|---|---|
| Capitation | Fixed PMPM | Control utilization |
| Fee-for-service | Per procedure | Increase volume |
| Salary (staff model) | Flat salary | Neutral on volume |
| DRG (hospitals) | Fixed per diagnosis | Shorten length of stay |
Concurrent and Retrospective Review
Beyond prospective (pre-certification) review, plans use concurrent review — monitoring care during a hospital stay to authorize continued days — and retrospective review after treatment to verify medical necessity before paying. Pair these with case management for high-cost chronic patients and a second surgical opinion program. The recurring exam point: pre-certification and concurrent review control cost before and during care, while retrospective review only affects whether the claim is paid.
Gatekeeping and Network Steerage as Cost Tools
Beyond reimbursement design, managed-care plans contain cost by steering members to efficient providers. The PCP gatekeeper controls specialist access, preferred-provider networks trade volume for discounted negotiated rates, and prior authorization lists force review before expensive services or drugs. Each tool reduces unnecessary utilization at a different point: gatekeeping at the referral stage, network contracts at the pricing stage, and authorization at the service-approval stage.
The exam pairs these with the review-timing trio (prospective, concurrent, retrospective) so candidates can place any described control on the timeline from before care through after the claim is submitted.
