Copay vs. Deductible: What Each One Means and How They Work Together

What is a deductible?

Your deductible resets at the start of each plan year (usually January 1st, or your enrollment anniversary) 1Ref 1U.S. Centers for Medicare and Medicaid Services (2024).Glossary of Health Coverage and Medical Terms.Official CMS definitions of copay, deductible, coinsurance, out-of-pocket maximum, and cost-sharing as used in ACA-compliant health plans. Until you have paid that full amount in covered services for the year, you pay the full allowed cost of most services yourself. After the deductible is met, your insurance begins paying its share.

Family plans typically have both an individual deductible and a combined family deductible. When the family total is reached, the whole family's costs start being shared — even if one person has not yet hit their individual limit. High-deductible health plans (HDHPs) qualifying for HSA use must have a minimum annual deductible of $1,650 for self-only coverage and $3,300 for family coverage in 2025 2Ref 2Internal Revenue Service (2025).Publication 969: Health Savings Accounts and Other Tax-Favored Health Plans.HDHP minimum deductible thresholds ($1,650 self-only / $3,300 family in 2025) and interaction between deductibles and HSA eligibility.

What is a copay?

A copay is a flat dollar amount tied to a specific type of visit or service 1Ref 1U.S. Centers for Medicare and Medicaid Services (2024).Glossary of Health Coverage and Medical Terms.Official CMS definitions of copay, deductible, coinsurance, out-of-pocket maximum, and cost-sharing as used in ACA-compliant health plans. It is usually printed on your insurance card: "PCP: $30 / Specialist: $60 / Urgent Care: $75 / ER: $350."

Copays are generally their own cost-sharing layer — they are not reduced or eliminated while you are still working toward your deductible. You pay the copay at the time of the visit, and it counts toward your out-of-pocket maximum. Whether it also counts toward your deductible depends on how your specific plan is structured.

How do copays and deductibles interact?

This is where most people get surprised.

On most standard (non-HDHP) plans, copays apply regardless of your deductible status. You pay the same $30 copay on visit one and visit fifty. However, services without a fixed copay — labs, imaging, procedures — are typically subject to the deductible first 1Ref 1U.S. Centers for Medicare and Medicaid Services (2024).Glossary of Health Coverage and Medical Terms.Official CMS definitions of copay, deductible, coinsurance, out-of-pocket maximum, and cost-sharing as used in ACA-compliant health plans. If your deductible is not yet met and your doctor orders bloodwork, you may owe the full allowed cost of those labs.

Once the deductible is met, you generally pay coinsurance (a percentage) rather than the full cost for those services.

High-deductible health plans (HDHPs) work differently: most services have no copay until the deductible is fully paid. After that, copays or coinsurance may apply 2Ref 2Internal Revenue Service (2025).Publication 969: Health Savings Accounts and Other Tax-Favored Health Plans.HDHP minimum deductible thresholds ($1,650 self-only / $3,300 family in 2025) and interaction between deductibles and HSA eligibility.

What is coinsurance, and how does it fit in?

Coinsurance is the percentage you pay after the deductible is met 1Ref 1U.S. Centers for Medicare and Medicaid Services (2024).Glossary of Health Coverage and Medical Terms.Official CMS definitions of copay, deductible, coinsurance, out-of-pocket maximum, and cost-sharing as used in ACA-compliant health plans. An "80/20" plan means insurance covers 80% and you cover 20% of the allowed cost once your deductible is satisfied.

The out-of-pocket maximum caps your total annual spending. It counts your deductible, coinsurance, and typically copays. Once you hit that ceiling, your insurance covers 100% of covered in-network services for the rest of the plan year 1Ref 1U.S. Centers for Medicare and Medicaid Services (2024).Glossary of Health Coverage and Medical Terms.Official CMS definitions of copay, deductible, coinsurance, out-of-pocket maximum, and cost-sharing as used in ACA-compliant health plans. For 2025, ACA-compliant individual plans cap out-of-pocket spending at no more than $9,200 for self-only coverage 2Ref 2Internal Revenue Service (2025).Publication 969: Health Savings Accounts and Other Tax-Favored Health Plans.HDHP minimum deductible thresholds ($1,650 self-only / $3,300 family in 2025) and interaction between deductibles and HSA eligibility.

A worked example

Say you have a $1,500 deductible, a $30 primary care copay, and 20% coinsurance after the deductible.

• January visit: You pay the $30 copay. Your doctor orders labs — you pay the full allowed cost of those labs, say $120, which counts toward your $1,500 deductible.
• August: You have paid $1,500 in covered services. Deductible met.
• Next lab order: You pay 20% of the allowed cost instead of the full amount.
• Every primary care visit: You still pay the $30 copay regardless.
• After your out-of-pocket maximum: The plan pays 100% for the rest of the year.

Where do I find my specific numbers?

Your Summary of Benefits and Coverage (SBC) — a standardized document your insurer must provide under the ACA — lists your deductible, out-of-pocket maximum, and copay tiers 3Ref 3U.S. Department of Health and Human Services (2024).Summary of Benefits and Coverage and Uniform Glossary.ACA requirement for health insurers to provide standardized Summary of Benefits and Coverage (SBC) disclosing deductible, out-of-pocket maximum, and copay tiers. Your insurer's member portal also shows your deductible accumulator in real time, so you can see how much you have paid toward it year-to-date.
