AB-554: Rules for HIV Prevention Drug Coverage

This vetoed bill would have required most health plans to cover FDA-approved drugs and devices that prevent HIV without extra approval steps or out-of-pocket costs.

What This Bill Does

  • Prohibits health insurers from requiring prior authorization or step therapy for medically necessary antiretroviral drugs, drug devices, or products used to prevent HIV/AIDS, unless at least one therapeutically equivalent version is already covered without these barriers.
  • States that long-acting drugs with different durations are not considered therapeutically equivalent, so plans cannot treat them the same under coverage rules.
  • Requires health plans covering non-self-administered FDA-approved HIV prevention treatments as a medical benefit to also include them as an outpatient prescription drug benefit.
  • Mandates that nongrandfathered health insurance policies must provide full coverage for FDA-approved drugs, devices, or products used for preexposure prophylaxis (PrEP) without any cost sharing like copayments or deductibles.
  • Stops insurers from charging costs for nonformulary HIV prevention drugs if they are therapeutically equivalent to a formulary drug that is already covered without cost.

Who It Names or Affects

  • Health care service plans regulated by the Department of Managed Health Care, excluding Medi-Cal managed care plans.
  • Health insurers regulated by the Department of Insurance.
  • People who need FDA-approved antiretroviral drugs or devices to prevent HIV/AIDS.
