Supporters of CA AB1887 would highlight that this bill is a crucial step towards equity in healthcare, ensuring that individuals with rare diseases have access to life-saving medications. They would argue that no one should have to choose between their health and financial stability, and this legislation helps to protect vulnerable populations. Advocates believe this bill reflects California's commitment to comprehensive healthcare for all residents.

Critics of CA AB1887 might argue that the bill could increase insurance premiums for all policyholders, as insurers may need to raise rates to cover the costs of mandated prescription drug coverage. They may also contend that the bill could lead to potential overregulation in the health insurance market, stifling innovation and limiting options for consumers. Additionally, some may question the feasibility of implementing such coverage requirements without sufficient funding or resources.
