## TL;DR

Most states require insurers to charge no more for a cancer pill than for an infusion, but the law does not reach the self-funded employer plans that cover most working Americans; a federal rule would close the gap.

## Summary

Oral anticancer drugs are usually covered under the pharmacy benefit with coinsurance on a specialty tier, while infused drugs fall under the medical benefit with a copay. Forty-three states and the District of Columbia have parity laws, but the federal ERISA statute exempts self-funded employer plans, which cover roughly two-thirds of workers with employer coverage. The Cancer Drug Parity Act has been introduced in successive Congresses to apply parity to all plans.

## Fields

- Kind: Idea
- Last checked: 2026-09-10
- Hypothesis: Federal parity will reduce the share of oral oncology prescriptions abandoned at the pharmacy for cost reasons among self-funded plan members by more than a third, at a premium cost of well under 1%.
- Rationale: State parity laws had small premium effects and reduced high out-of-pocket bills; the excluded population is the largest remaining group.
- Proposed test: Enactment followed by claims-based evaluation of abandonment rates and out-of-pocket costs in self-funded plans against state-regulated plans.
- Maturity: early-clinical
- Actor: policy
