What it does
This bill requires group health plans to charge patients the same out-of-pocket costs for oral cancer drugs (pills taken at home) as they do for intravenous cancer drugs administered in a clinic or hospital. It prevents insurers from raising costs, reclassifying benefits, or imposing stricter limits on oral drugs to comply. The bill takes effect January 1, 2026, and directs the Government Accountability Office to study its impact within two years.
Why we flagged it
The bill's core mechanism is a regulatory mandate requiring equal cost-sharing treatment for two drug delivery methods. It is a consumer-protection measure that constrains insurer pricing discretion, not a subsidy or carve-out.
What the text implies
- Oral anticancer drugs may become more attractive to insurers as a cost-containment strategy if they are genuinely cheaper to produce/dispense than IV drugs; parity pricing could shift treatment patterns toward oral formulations.
- The bill does not mandate coverage of oral anticancer drugs—only equal cost-sharing if covered. Insurers retain the right to exclude drugs or impose prior authorization, limiting the practical benefit for some patients.
- The GAO study (due 2 years post-enactment) may reveal that parity pricing increases overall plan costs, potentially triggering insurer responses such as higher premiums or narrower drug formularies.
- State laws providing greater protections are preserved, creating a patchwork of coverage rules across jurisdictions and potentially complicating multi-state plan administration.

Who it affects
Cancer patients gain access to oral medications at the same cost as IV alternatives, removing a financial barrier to treatment. The bill explicitly prohibits insurers from circumventing the requirement by raising costs or reclassifying benefits, protecting patients from cost-shifting.
Who stands to gain
- cancer patients (reduced out-of-pocket costs for oral medications)
- pharmaceutical manufacturers of oral anticancer drugs (potential increased demand if cost parity rem
