Medical Benefits and Expense Sharing

Plan Structures, Coverage Scope, and Dependent Rules

Health insurance policies differ in how they deliver care and how they reimburse medical providers. Fee-for-service plans pay medical providers for each individual service performed after care is delivered. Under a traditional fee-for-service arrangement, the insured may pay the provider and submit a claim for reimbursement, or the provider may bill the insurer directly. In contrast, prepaid health plans provide access to covered services in exchange for premiums paid in advance, though provider payment arrangements can vary. Prepaid health plans may pay providers by capitation or salary, although some also use fee-for-service payments.

Policies also vary by the scope of care they cover. Specified coverage policies insure only against named perils, specific diseases, or single events like accidents or dread diseases. Comprehensive health insurance covers a broad variety of medical expenses including inpatient, outpatient, preventive, and surgical care under one contract. Federal law sets baseline dependent coverage and special enrollment rights, while state insurance law may provide additional protections for insured policies. Self-funded employer plans are chiefly governed by federal law.

Under the Affordable Care Act, applicable health plans that offer dependent child coverage must generally make it available until the child reaches age 26; some limited-benefit plans are exempt. This dependent coverage up to age 26 applies regardless of the child's marital status, student status, or financial dependency. State law or plan terms may allow dependent coverage for a child who cannot support themselves because of a disability to continue after age 26, subject to eligibility and proof requirements.

Newborns and adopted children also receive statutory enrollment rights. A newborn generally can be enrolled in dependent health coverage effective from birth if applicable enrollment and premium requirements are met. To enroll a newborn, you must meet the notice and any additional premium requirements within the period set by applicable law and plan terms. Similarly, an adopted child may qualify for dependent coverage effective on the date of adoption or placement for adoption if applicable enrollment requirements are met.

Basic Medical Expense Policies

Basic medical expense plans traditionally provide low benefit limits and charge no deductible to the insured. These older policy forms were designed to cover initial, first-dollar expenses for hospital stays, surgeries, and physician visits rather than catastrophic events. Because they lack significant catastrophic protection, the coverage limits are often reached quickly during a severe illness.

Basic hospital expense coverage pays for daily room and board charges as well as miscellaneous hospital supplies and medication. A basic hospital policy may pay a fixed daily room-and-board benefit or reimburse covered room-and-board charges up to a daily limit, for a specified maximum number of days. Basic hospital miscellaneous benefits cover charges like operating room fees, laboratory tests, and X-rays up to a stated multiple of the daily room limit or a flat maximum.

Basic surgical expense policies pay covered surgeon's fees for inpatient or outpatient surgery, while coverage for other operating team members depends on the policy. Surgical fees in basic policies are determined using a surgical schedule, a relative value scale, or the usual, customary, and reasonable fee structure. A surgical schedule assigns a specific maximum dollar amount payable for each covered surgical operation listed in the policy. Under a usual, customary, and reasonable fee approach, the allowable charge reflects the provider's usual fee, prevailing local fees, and any case-specific factors rather than a fixed surgical schedule.

Basic physician expense coverage pays for covered nonsurgical physician visits, which may include hospital or office visits depending on the policy. This benefit is often subject to a limited dollar amount per physician visit and a maximum number of visits per illness.

Major Medical Insurance and Policy Designs

Major medical expense insurance is designed to protect against catastrophic medical costs resulting from serious illness or injury. While basic plans focus on initial expenses with low ceilings, major medical coverage is designed for high medical expenses. Under federal law, Affordable Care Act compliant plans cannot impose annual or lifetime dollar limits on essential health benefits.

Insurers package major medical protection in two distinct ways: supplemental major medical plans and comprehensive major medical plans. Supplemental major medical plans are written to coordinate with and provide coverage on top of an underlying basic medical policy. Supplemental major medical may pay eligible expenses that the basic plan does not pay, subject to the supplemental policy's terms; basic plan limits do not always have to be exhausted first. In contrast, comprehensive major medical plans combine basic hospital, medical, and surgical protections with major medical catastrophic coverage in a single contract. Comprehensive major medical coverage uses one policy for routine and high-cost care, but deductibles and other cost sharing can differ by service.

Understanding how basic plans integrate with major medical coverage is essential when evaluating plan designs. The following table contrasts the key features of these distinct policy approaches.

Expense Sharing: Deductibles, Coinsurance, and Stop-Loss

Major medical plans commonly use deductibles, coinsurance, or copayments to share covered costs with the insured. A deductible is the amount the insured pays for covered services subject to the deductible before the insurer begins paying for those services. A flat deductible is a fixed dollar amount an insured pays for covered expenses during a specified period, often a year. A per-cause deductible requires the insured to pay a separate deductible for each distinct illness, accident, or medical condition treated. A family deductible caps the combined deductible that covered family members must satisfy during the period specified in the plan.

Policies often contain specialized deductible rules. A common accident provision waives additional deductibles if two or more insured family members are injured in the same accident. A carryover provision, when included, may credit qualifying expenses incurred late in one benefit year toward the next year's deductible, as the policy specifies. In supplemental plans, a corridor deductible is an out-of-pocket amount the insured pays between the exhaustion of basic plan benefits and the start of supplemental major medical coverage. Alternatively, an integrated deductible applies basic plan benefits directly toward satisfying the major medical deductible.

After the deductible is satisfied, additional cost-sharing mechanisms apply. A copayment is a fixed amount the insured owes for a covered service, unlike percentage-based coinsurance. Coinsurance is a cost-sharing provision where the insurer and the insured split covered medical expenses according to a set percentage. An 80/20 coinsurance split is a common example: the insurer pays 80% of the allowed covered expense, and the insured pays 20%. For covered services subject to both a deductible and coinsurance, coinsurance generally applies after the deductible is met.

A stop-loss provision limits the insured's covered cost sharing during a specified period, subject to the policy's rules about which expenses count. After the applicable stop-loss limit is met, the insurer pays 100% of covered expenses subject to that limit for the remainder of the stated period, subject to policy terms and applicable law. To estimate out-of-pocket costs, add applicable deductibles, copayments, and the insured's coinsurance share of allowed covered charges, subject to the plan's out-of-pocket limit. Note that charges for noncovered services and amounts above the plan's allowed charge generally do not count toward its out-of-pocket limit.

Provider Reimbursement and Out-of-Pocket Calculations

In fee-for-service environments, claim payouts often depend on whether charges meet the insurer's fee standards. Usual, customary, and reasonable charges reflect a provider's usual fee, prevailing local fees for the service, and adjustments for the circumstances of the case. In a fee-for-service plan, an insured may owe charges above the plan's allowed amount when a provider is permitted to balance bill, subject to applicable protections.

Consider a client example to see how cost sharing works in practice. Suppose an insured has a comprehensive major medical policy with a $1,000 flat annual deductible, an 80/20 coinsurance split, and a $5,000 out-of-pocket limit that counts both the deductible and coinsurance. The insured incurs $11,000 in covered medical expenses for an inpatient hospital stay, and all expenses represent allowed charges. The insured first pays the $1,000 deductible, leaving $10,000 in covered charges. Applying the 80/20 coinsurance split, the insurer pays 80% ($8,000) and the insured pays 20% ($2,000). In total, the insured pays $3,000 ($1,000 deductible plus $2,000 coinsurance), which is well below the $5,000 stop-loss limit.

If that same insured later incurs an additional $30,000 in covered allowed charges during the same benefit year, the remaining out-of-pocket obligation is capped. Having already paid $3,000 toward the $5,000 stop-loss limit, the insured pays only $2,000 more in coinsurance. Once the $5,000 stop-loss limit is met, the insurer pays 100% of remaining covered expenses subject to that limit for the rest of the period.
