9.3 Managed Care: HMO, PPO, POS, and HSA/HDHP

Managed care controls cost and quality by integrating financing with the delivery of care. The exam tests how each model restricts provider choice, whether a primary care physician (PCP) and referrals are required, and how HSAs pair with high-deductible plans.

The Four Managed Care Models

The defining HMO trait is that care must be received from network providers and coordinated by a PCP gatekeeper; going out-of-network means no coverage except for true emergencies.

HMO Mechanics

HMOs emphasize preventive care and charge copayments rather than deductibles and coinsurance for most services. Key HMO concepts:

• Capitation — the HMO pays providers a fixed amount per member per month regardless of services used, shifting cost risk to the provider.
• Gatekeeper PCP — the member selects a PCP who coordinates all care and issues referrals to specialists.
• Service-area limitation — coverage is geographic; routine out-of-area care is not covered.

PPO Mechanics

A PPO contracts with preferred providers who accept negotiated discounted fees. Members may use any provider but pay less in-network and more out-of-network. There is no PCP gatekeeper and no referral requirement, giving the most flexibility of the managed-care models. PPOs typically use deductibles and coinsurance rather than flat copays for many services.

POS Plans

A Point-of-Service (POS) plan blends HMO and PPO features. The member chooses a PCP gatekeeper (HMO-style) but may go out-of-network with a referral (PPO-style) by paying higher cost-sharing. The decision is made at the point of service — each time care is needed.

HSA and HDHP Pairing

A Health Savings Account (HSA) is a tax-advantaged account that must be paired with a qualified High-Deductible Health Plan (HDHP). Tax treatment is favorable on all three sides:

• Contributions are tax-deductible (or pre-tax via payroll).
• Earnings grow tax-deferred.
• Withdrawals for qualified medical expenses are tax-free.

Unlike an FSA, HSA balances roll over year to year and the account is portable — owned by the individual, not the employer.

HSA/HDHP Rules and Penalties (worked figures)

IRS rules define HDHP minimum deductibles and HSA contribution limits, indexed annually. Memorize the structure and approximate ranges rather than exact figures:

Penalty trap: Non-qualified HSA withdrawals before age 65 are taxed as income plus a 20% penalty. After age 65, non-qualified withdrawals are taxed as ordinary income but the 20% penalty no longer applies. A person enrolled in Medicare may not make new HSA contributions.

Other Consumer-Directed Accounts

The exam contrasts the HSA with two similar-sounding accounts. Keep the differences crisp:

• An FSA is funded by employee salary reductions; unused funds are generally forfeited at year-end (subject to a small carryover or grace period).
• An HRA is employer-funded only — employees cannot contribute — and the employer decides whether unused amounts carry over.

A classic distractor pairs an HSA with a low-deductible PPO; remember the HSA must be paired with a qualified HDHP, never a low-deductible plan.

Referrals, Networks, and Emergency Care

The referral mechanism is the operational heart of an HMO and a POS plan. Without a PCP referral, an HMO member who self-refers to a specialist generally has no coverage for that visit. The exam often presents a member who sees a dermatologist without a referral and asks how the claim is handled — under a true HMO, the answer is that the plan denies the claim because the gatekeeper process was bypassed.

Emergency exception: Even strict HMOs must cover emergency care, including out-of-area and out-of-network emergencies, under the prudent-layperson standard. A member experiencing chest pain who goes to the nearest hospital is covered regardless of network status. This is one of the few times an HMO pays for non-network care, and it is heavily tested.

Network Status and Member Cost

The single biggest cost variable for a member is whether a provider is in-network. Across all managed-care models, in-network care carries the lowest cost-sharing, and out-of-network care carries higher cost-sharing or no coverage at all.

• HMO/EPO: out-of-network = no coverage (except emergencies).
• PPO/POS: out-of-network = covered but with higher deductibles and coinsurance, plus possible balance billing above UCR.

When advising clients, an agent must confirm that the client's preferred physicians and hospitals participate in the plan's network before recommending it. A plan with a great premium but a narrow network that excludes the client's doctors is a poor fit — a common scenario tested as a suitability question. Always tie the recommendation back to the client's providers, travel needs, and tolerance for cost-sharing.

Choosing Among the Models

Agents must match a client's priorities to the right plan. The exam frames this as trade-offs between cost, choice, and coordination:

• Lowest premium, most restrictions → HMO. Best for clients who value low copays and do not mind a gatekeeper and a closed network.
• Maximum provider freedom → PPO. Best for clients who travel, want out-of-network access, and accept higher cost-sharing.
• Middle ground → POS, combining a gatekeeper with out-of-network flexibility.
• Tax-advantaged savings with a high deductible → HDHP + HSA, ideal for healthier clients who want to build a tax-favored medical fund.

Managed care plans also emphasize wellness and preventive programs — screenings, immunizations, and disease-management initiatives — because preventing illness is cheaper than treating it. This is why ACA-compliant managed care must cover in-network preventive care with no cost-sharing, reinforcing the cost-containment theme carried into Section 9.4.
