Read this first: which plans this table reaches
Every row below is state insurance law. It reaches plans the state regulates — fully-insured employer plans, individual and small-group policies, HMOs, and in some states Medicaid managed care. It does not reach self-funded (ERISA) employer plans, which cover roughly 63% of workers with employer coverage, and it never reaches Medicare or Medicare Advantage. So before you tell a patient their copay card will count toward the deductible, confirm the plan is not self-funded. The "reaches" column records what each statute's own text says it covers.
What an accumulator law does
A manufacturer copay card pays most of a specialty drug's cost-share on the patient's behalf. An accumulator adjustment program accepts that money but does not count it toward the patient's deductible or out-of-pocket maximum — so when the card's annual value runs out, the patient's deductible is still untouched and the next infusion is full cost-share. A maximizer goes further and sets the cost-share to drain the card's full value. State accumulator laws require the plan to count third-party payments toward the deductible and out-of-pocket maximum as if the patient paid them. Most carve out a brand drug that has a generic or biosimilar the plan covers, unless the brand was reached through prior authorization or a medical exception.
For a patient-access or financial-navigation desk this is the difference between a benefits check that holds for the year and one that collapses in month four. 25 of 51 jurisdictions have a law we confirmed against the state's own text (2 more are reported by trackers but not yet confirmed); the rest have none we could find, and the federal rule is unsettled (see the FAQ).

"yes" under the exception column links to the state's entry, which quotes the carve-out. "No" with a Confirmed badge means we checked the state's own code or insurance department and found no accumulator provision as of September 20, 2026. Bills pending in a legislature are noted in the state entry, not counted as law.
What to do at the benefits check
- Ask the plan directly whether it runs an accumulator or maximizer on this drug. The answer is a plan-design fact the representative can read; get the name of the program and note it on the verification.
- If the state has a law and the plan is state-regulated, cite it. The entries below give the section. The plan must count the card's payments; if the portal shows the deductible untouched after a card-paid infusion, that is the dispute.
- Check the generic-exception carve-out before promising anything. Where the drug has a covered biosimilar, most laws let the plan exclude the brand unless it came through prior auth or an exception.
- Self-funded plan? The state law does not reach it. Plan the year on the card's face value, and route the patient to foundation assistance early.

Frequently asked
- What is the difference between an accumulator and a maximizer?
- An accumulator accepts the copay card's payments but does not count them toward the deductible or out-of-pocket maximum. A maximizer additionally sets the drug's cost-share to the card's full annual value, spread across the year, so the card is exhausted by design. State laws written as "must count third-party payments" address both.
- Does the law reach my patient's employer plan?
- Only if the plan is fully-insured (the employer buys a policy from a carrier). A self-funded plan — the employer pays claims itself, typically with a carrier as administrator — is governed by ERISA and the state law does not apply. The plan's SPD or a call to the plan says which; the carrier's logo does not.
- What about the generic exception?
- Most laws let a plan keep an accumulator on a brand drug when a generic or interchangeable biosimilar is covered, unless the brand was obtained through prior authorization, step therapy or a medical exception. For infused biologics with biosimilars — infliximab, rituximab, bevacizumab, trastuzumab, denosumab — that carve-out decides whether the law helps at all. The state entry says whether the text has one.
- Is there a federal rule?
- Not a settled one. In HIV and Hepatitis Policy Institute v. HHS (D.D.C., Sept. 29, 2023) a federal court set aside the 2021 federal provision that had let plans exclude manufacturer assistance from the cost-sharing limit, and HHS has stated it intends further rulemaking on “the applicability of drug manufacturer support to the annual limitation on cost sharing” (89 FR 82308, Oct. 10, 2024). Until that rule is final, state law is what a patient-access desk can rely on. This page tracks state law only.
- Where does foundation assistance fit?
- Foundation grants are also third-party payments and most state laws count them the same way. When the plan is self-funded or the drug falls under a generic exception, the card will run out; routing the patient to a foundation fund before that happens is the practical fix.
