AB-298: Health Care Coverage Cost Sharing

This law stops large group health plans from charging deductibles, copayments, or coinsurance for in-network medical services given to people under 21 years old.

What This Bill Does

  • Prohibits large group health care service plan contracts and health insurance policies issued, amended, or renewed on or after January 1, 2027, from requiring cost sharing for in-network health care services provided to enrollees under age 21.
  • Bans individuals or entities from billing or seeking reimbursement for in-network health care services provided to enrollees under the age of 21.
  • Notes that a willful violation of these rules by a health care service plan is considered a crime because existing law already makes such violations criminal.
  • States that no state reimbursement is required from this act for local agencies.

Who It Names or Affects

  • Large group health insurance policies and contracts issued, amended, or renewed on or after January 1, 2027.
  • Enrollees or insured individuals under the age of 21 receiving in-network care.
  • Health care service plans regulated by the Department of Managed Health Care.

Terms To Know

Cost sharing
Money a patient must pay, such as deductibles, copayments, or coinsurance.
In-network services
Health care services provided by providers who have agreed to work with the insurance plan at set prices.

Limits and Unknowns

  • The law includes exceptions where cost sharing may still be allowed as specified elsewhere in the bill.
  • The official text shows conflicting dates (2026 and 2027) for when the rules take effect, though 2027 is listed last.
