Copay Maximizer

A variant of copay accumulator that calibrates the patient copay for a specialty drug to extract the maximum available manufacturer assistance, spreading it across the year.

How It Works

Copay maximizers are a newer and more aggressive insurer strategy than accumulators. Under a maximizer program, the plan sets the patient's copay on a specialty drug to a specific amount, typically calibrated to exhaust the manufacturer's entire annual copay card maximum evenly across 12 months, so the drug is effectively free to the patient all year but none of the manufacturer payments count toward deductible or OOP maximum. A patient on a $10,000/year specialty drug might see a $833/month copay, exactly matching a $10,000 annual manufacturer copay card, paying $0 herself. This captures all manufacturer assistance for the insurer's benefit while maintaining patient access. Maximizer vendors (PrudentRx, SaveOnSP, HealthPlan Data Solutions, Payer Matrix) are retained by self-funded plans. Unlike accumulators, maximizers do not produce a mid-year cliff because the calibrated copay matches assistance. However, drugs excluded from maximizer programs (because of Essential Health Benefit requirements or because the manufacturer blocks maximizer use) may see patients dropped entirely from assistance. Pharmaceutical manufacturers have responded by adding maximizer-exclusion language to copay cards (e.g., "not valid if patient is enrolled in a variable copay or accumulator program"). Litigation over maximizers is active: J&J sued SaveOnSP in 2022 (SDNY) alleging tortious interference with copay card programs; the case survived motions to dismiss in 2023 and is proceeding. Maximizer bans are generally less advanced than accumulator bans, with California enacting the first comprehensive ban effective 2024.
