What Is Aggregate Deductible In Health Insurance

Family health insurance policies utilize an aggregate deductible, requiring the entire family to pay the deductible before the insurance company covers services for any family member.

Previously, many high-deductible health plans (HDHPs) adopted aggregate deductibles for families, differing from the embedded deductibles in non-HDHP health insurance.

Rule adjustments have been implemented to protect consumers in plans with these deductibles.

Let’s delve into how aggregate deductibles work and the regulatory changes ensuring consumer protection.

Changes That Took Effect in 2016

Since 2016, family health plans must have embedded out-of-pocket maximums, capped at individual maximums for the year.

For instance, in 2023, the limit is $9,100 and in 2024, it will be $9,450.

Plans can’t have an aggregate deductible exceeding these limits but can have family deductibles higher than the individual limit, applicable only if multiple family members have claims.

This ensures fair coverage and prevents excessive costs for individual family members.

Let’s explore how aggregate deductibles function further.

How Does an Aggregate Deductible Work?

An aggregate family deductible means the health plan covers family healthcare expenses only when the entire family pays the deductible.

This can happen when multiple family members individually pay toward the deductible, or if one member incurs high expenses, fulfilling the total amount.

Once the family reaches the aggregate deductible, the plan begins covering their healthcare costs, either fully or with applicable coinsurance.

What Expenses Count Toward the Family Aggregate Deductible?

For your High Deductible Health Plan (HDHP) to count expenses toward the aggregate deductibles, they must be for covered health benefits and adhere to plan rules, including prior authorization and referrals.

In HMOs or EPOs, services typically require in-network providers. PPOs or POS plans may cover out-of-network care but with higher deductibles.

The provider processes in-network claims, and your insurer’s explanation of benefits shows the progress toward the deductible.

For out-of-network providers, you might need to file claims yourself, even if you pay the full cost.

Some plans cover out-of-network care in emergencies, but not always.

Understanding your plan is crucial.

What Expenses Are Exempt From Aggregate Deductibles?

Under the Affordable Care Act in the US, health plans must cover specific preventive healthcare services without cost-sharing.

This includes flu shots, kids’ immunizations, and screening mammograms, even before meeting the deductible.

Note that only services on a specific covered list qualify, and if not, cost-sharing might apply.

How Aggregate Deductibles Work in 2016 and Beyond

Since 2016, health plans can’t require individuals to pay deductibles exceeding the federal out-of-pocket maximum limit (e.g., $9,100 in 2023).

For instance, if your family plan’s aggregate deductible is $12,000 in 2023, once any family member pays $9,100, their coverage begins without additional cost-sharing.

Other family members’ coverage starts only after the entire $12,000 aggregate deductible is met.


Aggregate deductibles allow any family member to meet the entire family deductible, though this practice is rare except for HSA-qualified high-deductible plans.

Since 2016, new rules restrict a single family member’s out-of-pocket costs to the annual individual limit, applying to all major medical plans regardless of deductible type, except for grandfathered or grandmothered plans.
