9.4 Cost Containment and Provider Arrangements
Key Takeaways
- Cost containment uses precertification (before), concurrent review (during), and case management (ongoing).
- HMO models include staff, group, IPA, and network structures.
- Capitation shifts utilization risk to providers; PPOs use discounted fee-for-service.
- UCR limits payment to area norms; out-of-network providers may balance bill the excess.
- Coordination of benefits assigns primary and secondary payers so total reimbursement never exceeds 100%.
Because medical inflation outpaces general inflation, every modern health plan embeds cost-containment features. The exam expects you to recognize each technique, why it controls cost, and how providers are organized and reimbursed.
Utilization Management Techniques
| Technique | Purpose |
|---|---|
| Precertification / prior authorization | Approves non-emergency hospital admissions or procedures before they occur |
| Concurrent review | Monitors the necessity and length of an ongoing inpatient stay |
| Second surgical opinion | Confirms elective surgery is necessary before it is approved |
| Case management | Coordinates care for high-cost, complex cases to reduce duplication |
| Mandatory outpatient/ambulatory surgery | Steers minor procedures away from costly inpatient settings |
| Gatekeeper PCP | Coordinates and authorizes specialist and facility use |
Key Point: Precertification is prospective (before care); concurrent review is during the stay; case management is ongoing for catastrophic claims.
Network Design and Preventive Care as Cost Controls
Beyond authorizations, plans contain cost structurally. Tiered networks give members lower cost-sharing for using preferred, cost-effective providers. Generic-first drug formularies and step therapy steer prescriptions toward lower-cost equivalents. Wellness and preventive programs (screenings, immunizations) catch disease early, when treatment is cheaper. Disease-management programs coordinate care for chronic conditions such as diabetes to avoid expensive complications and admissions.
These tools matter on the exam because each reduces the plan's claim cost in a different way: utilization review limits unnecessary services, network design lowers the unit price, and prevention reduces the frequency and severity of future claims. Recognizing which lever a described program pulls is a common question pattern.
Provider Arrangements and Reimbursement
Managed-care plans organize and pay providers in distinct ways. The exam tests the HMO structural models:
| HMO Model | Structure |
|---|---|
| Staff model | Physicians are salaried employees of the HMO, practicing in HMO facilities |
| Group model | HMO contracts with one multi-specialty group practice |
| IPA (Independent Practice Association) model | HMO contracts with an association of independent physicians who keep their own offices and also see non-HMO patients |
| Network model | HMO contracts with multiple group practices |
Reimbursement Methods
- Capitation — fixed per-member-per-month payment; provider bears utilization risk and is incentivized to manage cost.
- Discounted fee-for-service — contracted (preferred) providers accept reduced fees for patient volume; common in PPOs.
- Salary — used in staff-model HMOs.
- DRG (Diagnosis-Related Group) — fixed payment per diagnosis category (a Medicare hospital method) that discourages unnecessary length of stay.
UCR, Balance Billing, and Coordination of Benefits
Usual, Customary, and Reasonable (UCR) charges define the maximum a plan will pay for a service in a geographic area. If a non-network provider charges above UCR, the patient may face balance billing for the excess. Staying in network protects against this because contracted providers accept the plan's allowed amount.
Coordination of Benefits (COB)
When a person is covered by two plans, COB prevents the insured from collecting more than 100% of expenses by assigning a primary payer (pays first, as if no other coverage) and a secondary payer (pays remaining eligible expenses up to its limits).
Worked COB example: A $4,000 covered bill. The primary plan pays $3,000. The secondary plan would have paid $3,500 on its own; it pays only the unpaid $1,000, so total reimbursement equals the $4,000 bill — not $6,500.
Birthday rule: For a child covered under both parents, the plan of the parent whose birthday falls earlier in the calendar year is primary (the year is irrelevant).
COB Order-of-Benefit Rules
When two plans cover the same person, NAIC model COB rules set the order:
- A plan covering the person as an employee/member is primary over one covering them as a dependent.
- For a dependent child of married parents, the birthday rule applies (earlier birthday in the year is primary).
- For a dependent child of divorced parents, the plan of the parent with custody (or as a court decree assigns) is primary.
- An active employee plan is primary over a retiree/COBRA plan.
These rules prevent gaps and overlaps. Remember that COB applies to reimbursement coverage; fixed-sum indemnity benefits (hospital indemnity, critical illness) pay in addition and are not coordinated, because they are not tied to actual expense and cannot produce a profit on a per-expense basis.
Subrogation
Many medical plans include a subrogation clause: after paying a claim caused by a third party (such as an at-fault driver), the insurer may pursue recovery from that party. This keeps a negligent third party — not the insurance pool — ultimately responsible, helping contain overall plan cost. Subrogation, COB, and UCR together ensure the plan pays no more than its fair share of any loss.
How Plans Hold Down Cost
Cost-containment questions test the toolbox plans use to manage utilization and price. Utilization review screens care for medical necessity through precertification (prior authorization before a non-emergency hospital stay), concurrent review (monitoring an ongoing stay), and retrospective review (after the fact). Case management coordinates care for high-cost patients, and a second surgical opinion provision discourages unnecessary procedures.
On the price side, plans negotiate provider arrangements such as capitation (a fixed per-member-per-month payment that shifts utilization risk to the provider) and discounted fee-for-service in PPO networks.
The recovery mechanisms ensure the plan pays only its fair share. Coordination of benefits orders primary and secondary payers when an insured has two plans; subrogation lets the plan recover from a liable third party after it has paid; and usual, customary, and reasonable (UCR) limits reimbursement to the prevailing charge for the area.
| Tool | Function |
|---|---|
| Precertification | Approve non-emergency care in advance |
| Capitation | Fixed per-member payment shifts risk to provider |
| UCR | Caps reimbursement at the area's prevailing charge |
Exam Trap: Subrogation makes the at-fault third party — not the insurance pool — ultimately responsible, which helps contain plan cost. Together, subrogation, coordination of benefits, and UCR ensure the plan never pays more than its fair share of any loss.
An insured is covered by two group plans. A covered charge is $4,000. The primary plan pays $3,000. Under coordination of benefits, how much will the secondary plan pay if it would have covered the full amount on its own?
