Surprise Billing Protections in California

California’s Own Surprise Billing Law (AB 72 / SB 1185):

California enacted surprise billing protections before the federal No Surprises Act. AB 72 applies to DMHC-regulated plans (most HMOs), capping out-of-network costs at the in-network rate. The federal No Surprises Act covers ERISA and self-funded plans. Together, virtually all insured Californians are protected.

  • Emergency Services: You cannot be balance billed for emergency care at any hospital, regardless of network status (state + federal law)
  • Non-Emergency at In-Network Facilities: Out-of-network clinicians (anesthesiologists, radiologists, pathologists, etc.) at in-network hospitals cannot balance bill you
  • Ground Ambulance: AB 1004 created California’s own Independent Dispute Resolution process for ground ambulance billing disputes
  • Air Ambulance: Covered under the federal No Surprises Act — you pay only in-network cost-sharing

What You Should Pay:

Only your in-network cost-sharing (copay, coinsurance, deductible). The provider and insurer must work out the rest — you are not responsible for the difference between in-network and out-of-network rates.

If You Receive a Surprise Bill:

  1. 1. Don’t pay it immediately
  2. 2. Call your insurance to confirm it’s being processed correctly
  3. 3. File a complaint with DMHC (HMO) or CDI (PPO/other)
  4. 4. For federal plan issues, file at cms.gov/nosurprises or call 1-800-985-3059

Financial Assistance & Charity Care

California Hospital Fair Pricing Act (AB 774 / SB 1276):

  • Mandatory Charity Care: Nonprofit hospitals must provide financial assistance and post policies publicly. Patients must be screened for eligibility before any collections activity
  • Uninsured Patient Protections: Hospitals cannot charge uninsured patients more than what they accept from insured patients for the same services
  • Coverage Screening Required: Hospitals must screen patients for Medi-Cal and Covered California eligibility before pursuing collections
  • Right to Manager Review (HSC 127405): If you dispute a financial assistance determination, you have the legal right to request review from the hospital’s business manager, CFO, or other designated manager — not just the billing clerk

California Eligibility Thresholds:

100% Free Care: Below 200% Federal Poverty Level (FPL)

Sliding Scale Discounts: 200-400% FPL — reduced rates based on income

Uninsured Rate Cap: Cannot be charged more than what insurers pay

No Asset Test: Hospitals can only consider income, not savings or assets (AB 2297)

Payment Plans: Interest-free plans required by law (SB 1061)

If Your Financial Assistance Application Is Denied:

California law gives you a 3-tier appeal path:

  1. 1. Request Manager Review — Under HSC 127405(a)(1)(A), ask for the business manager, CFO, or designated manager listed in the hospital’s charity care policy. The hospital’s determination letter must include this contact information.
  2. 2. File an HCAI Complaint — If the internal review doesn’t resolve it, file a complaint with HCAI’s Hospital Bill Complaint Program. HCAI can penalize hospitals that violate the Fair Pricing Act.
  3. 3. Administrative Hearing — Further disputes can be escalated to a formal administrative hearing.

Collections & Credit Reporting

ProtectionCalifornia LawWhat It Means
Credit ReportingAB 1526 (2022)Most medical debt banned from CA credit reports
Collections Waiting Period180 daysHospitals must wait before sending to collections
Statute of Limitations4 years (CCP 337)Time limit for legal action on medical debt
Wage GarnishmentCCP 706.050Limited to 25% of disposable earnings; retirement and benefits exempt
Homestead ExemptionCCP 704.730Primary residence protected from medical debt judgments

Important: California’s AB 1526 goes further than federal rules — most medical debt cannot appear on your credit report at all. Additionally, hospitals must offer financial assistance screening and payment plans before pursuing any collections activity.

Payment Plans & Hardship Policies

Your Payment Rights in California (SB 1061):

Interest-Free Payment Plans Required

  • • Hospitals must offer interest-free payment plans by law
  • • Monthly payments capped at 5% of monthly income for qualifying patients
  • • Cannot be sent to collections while payment plan is active and current
  • • Must be offered before hospital pursues any legal action

Prompt Pay & Self-Pay Discounts

  • • Many hospitals offer 10-40% for paying promptly
  • • Ask: “What is your self-pay or cash discount?”
  • • Uninsured patients cannot be charged more than insured rates
  • • Get any discount agreement in writing

Hardship Programs

  • • Job loss, disability, or family emergency qualifications
  • • May reduce or eliminate balance entirely
  • • Hospitals must screen for Medi-Cal and Covered California before collections

How to Dispute a Bill (Step-by-Step)

1

Request Itemized Bill

Call billing and say: "I need a fully itemized bill with line items, CPT codes, and descriptions." California hospitals must provide itemized bills upon request.

1 phone call

2

Review for Errors

Common issues: Duplicate charges, upcoding (billing for a more complex service), unbundling (charging separately for included items), and services not received.

30 minutes

3

Gather Documentation

Collect: Medical records, insurance EOB, previous bills, notes from appointments, discharge papers. Log all phone calls with dates and representative names.

1 hour

4

Submit Written Dispute

Send certified mail with: Cover letter explaining errors, copies of supporting documents, request for corrected bill and billing hold during review.

1 hour

5

Apply for Financial Assistance

Request a financial assistance application under the Hospital Fair Pricing Act. If denied, you have a legal right under HSC 127405 to request review from the hospital's business manager or CFO — not just the billing clerk who processed your application.

30-60 minutes

6

Escalate if Needed

If unresolved after 30 days: File a complaint with DMHC (HMO issues), CDI (PPO/insurance), the California Attorney General (billing fraud), or HCAI's Hospital Bill Complaint Program (financial assistance violations). Request an Independent Medical Review if your claim was denied.

Frequently Asked Questions

Does California have its own surprise billing law?
Yes. California enacted AB 72 and SB 1185, which predate the federal No Surprises Act. For DMHC-regulated plans (most HMOs), AB 72 caps out-of-network costs at the in-network rate. The federal No Surprises Act covers ERISA and self-funded plans. Together, virtually all insured Californians are protected from surprise balance billing for emergency and certain non-emergency services.
Can medical debt appear on my credit report in California?
California law (AB 1526, effective 2022) bans most medical debt from appearing on California credit reports. This goes beyond federal rules, which only block debts under $500 and require a 365-day waiting period. AB 1526 broadly prohibits consumer credit reporting agencies from including medical debt information.
What is the charity care requirement for California hospitals?
Under the California Hospital Fair Pricing Act (AB 774 / SB 1276), nonprofit hospitals must provide free care to patients below 200% of the Federal Poverty Level (FPL) and discounted care on a sliding scale for patients between 200-400% FPL. Hospitals cannot charge uninsured patients more than what they accept from insured patients, and must screen patients for Medi-Cal and Covered California eligibility before pursuing collections. If your application is denied, you have a legal right under HSC 127405 to request review from the hospital’s business manager or CFO, and can escalate to HCAI’s Hospital Bill Complaint Program.
How long do I have to dispute a medical bill in California?
Request an itemized bill right away. California has a 4-year statute of limitations on medical debt (CCP 337). Hospitals must wait at least 180 days before sending bills to collections, and must offer financial assistance screening and payment plans first. For surprise billing complaints, file with the DMHC or CDI at any time.
Can my wages be garnished for medical debt in California?
California provides strong protection against wage garnishment for medical debt. Under CCP 704.730, your primary residence is protected by a generous homestead exemption, and California law limits the amount that can be garnished from wages. Retirement accounts, Social Security, and disability benefits are fully exempt from medical debt collection.
How do I file a complaint against a hospital or insurer in California?
File complaints with: the Department of Managed Health Care (DMHC) at 1-888-466-2219 for HMO and managed care issues, the California Department of Insurance (CDI) at 1-800-927-4357 for PPO and insurance issues, HCAI’s Hospital Bill Complaint Program for financial assistance and Fair Pricing Act violations, or the California Attorney General at 1-800-952-5225 for billing fraud and unfair practices. The federal No Surprises Help Desk (1-800-985-3059) handles federal surprise billing violations.
