California Medical Billing Laws
California has among the strongest patient billing protections in the country. AB 72 (2017) prohibits balance billing for non-emergency services at in-network facilities when the patient is treated by an out-of-network provider. The Hospital Fair Pricing Act (AB 774 and AB 1020) caps charges for uninsured patients — hospitals cannot charge uninsured patients more than the amount paid by Medicare or Medi-Cal plus a percentage. All California hospitals must have financial assistance policies, must screen patients for eligibility, and must wait at least 150 days after the first billing statement before sending a bill to collections. The Department of Managed Health Care (DMHC) handles complaints for HMO and some PPO plans, while the Department of Insurance handles complaints for other insurance products. California's Rosenthal Act extends debt collection protections to original creditors, giving patients more rights than in most states.
California has some of the strongest medical debt protections in the nation. AB 1020 and AB 532 require hospitals to screen patients for financial assistance eligibility before pursuing collections. The statute of limitations on medical debt is 4 years under CCP Section 337. SB 1061 (2022) prohibits medical debt from being reported to credit bureaus until it has been delinquent for at least 12 months, aligning with federal rules. California's Rosenthal Fair Debt Collection Practices Act extends FDCPA-like protections to original creditors (hospitals), not just third-party collectors.

How to Dispute a Medical Bill in California
Request an itemized bill with all CPT/HCPCS and ICD-10 codes from the hospital
Check if the bill violates AB 72's balance billing protections — if you were treated at an in-network facility by an out-of-network provider, you should only owe in-network cost-sharing
Verify if you qualify for the Hospital Fair Pricing Act discounts — uninsured patients should not be charged more than the AGB (amounts generally billed to insured patients)
