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. Don’t pay it immediately
- 2. Call your insurance to confirm it’s being processed correctly
- 3. File a complaint with DMHC (HMO) or CDI (PPO/other)
- 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. 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. 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. Administrative Hearing — Further disputes can be escalated to a formal administrative hearing.
Collections & Credit Reporting
| Protection | California Law | What It Means |
|---|---|---|
| Credit Reporting | AB 1526 (2022) | Most medical debt banned from CA credit reports |
| Collections Waiting Period | 180 days | Hospitals must wait before sending to collections |
| Statute of Limitations | 4 years (CCP 337) | Time limit for legal action on medical debt |
| Wage Garnishment | CCP 706.050 | Limited to 25% of disposable earnings; retirement and benefits exempt |
| Homestead Exemption | CCP 704.730 | Primary 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)
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
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
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
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
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
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.

Between DMHC, CDI, and hospital billing departments, the dispute process can be time-consuming. If you’d rather have someone handle it, our Bill Defense team manages everything — you pay nothing unless we reduce your bill.
