Medical Bill Disputes in Colorado: Your Rights and Options
In 2022, Colorado became one of the first states to pass a law prohibiting medical debt from being reported to credit bureaus — years before the federal rule. But thousands of Colorado patients still receive collection notices that threaten their credit because providers and collectors don’t always follow the law.

Key Colorado Consumer Protections
Colorado’s Surprise Billing Protections
Colorado enacted HB 1174 (2019) and subsequent legislation to protect patients from surprise billing at in-network facilities and in emergency situations. Colorado’s surprise billing law applies to state-regulated health insurance plans and provides protections that align with and in some areas supplement the federal No Surprises Act.
Federal No Surprises Act (2022)
The federal law applies to most Colorado patients with private insurance, including ERISA employer plans. For state-regulated plans, whichever rule provides greater patient protection applies.
Colorado’s Medical Debt Protections (HB 1285, 2022)
Colorado enacted significant medical debt protections in 2022:
- Hospitals must offer financial assistance to patients with incomes up to 250% of the federal poverty level before sending accounts to collections
- Hospitals must provide a “plain-language” billing statement before sending to collections
- Medical debt is excluded from certain credit judgments and lien protections
- Hospitals cannot charge interest on medical debt for patients below income thresholds
Colorado’s Hospital Financial Assistance Requirements
Colorado law requires hospitals to have financial assistance programs and to screen patients for eligibility. The income thresholds in Colorado tend to be generous, and the state has been active in expanding these protections.
Colorado Medicaid (Health First Colorado)
Colorado’s Medicaid program — Health First Colorado — expanded under the ACA and covers a significant portion of the state’s population. Health First Colorado members have separate billing protections through their managed care plan.

How to Dispute a Medical Bill in Colorado
Step 1: Request your itemized bill. Ask for a complete, line-by-line breakdown. Use our EOB decoder to review your insurance Explanation of Benefits.
Step 2: Identify errors. Check for balance billing violations, upcoding, duplicate charges, and failure to screen for financial assistance before collection. See our billing errors guide.
Step 3: Contact the provider. Send a formal written dispute. In Colorado, mention specifically whether you requested financial assistance and whether the hospital screened you before issuing the bill.
Step 4: File a grievance with your insurer. Colorado-regulated plans must have internal grievance processes. File in writing.
Step 5: File with DORA. If unresolved, file a consumer complaint with DORA. The division actively enforces surprise billing violations.
Step 6: External review. Colorado has external review procedures for denied claims through DORA.

Colorado’s Medical Debt Collection Protections
Colorado passed House Bill 23-1126 in 2023, making it one of a small group of states to prohibit medical debt from appearing on consumer credit reports. Under the law, medical debt incurred by Colorado residents cannot be included in credit bureau reports, regardless of when the debt was incurred or whether it was placed with a collection agency.
Importantly, Colorado also passed Senate Bill 23-093, which requires hospitals to:
- Screen patients for financial assistance eligibility before sending any bill to collections
- Offer interest-free payment plans of at least 36 months for patients who qualify for charity care
- Provide written notice of financial assistance programs in plain language (English and Spanish)
- Halt all collection activity while a financial assistance application is pending
If a Colorado hospital violates these requirements, you can file a complaint with the Colorado Department of Health Care Policy & Financing (HCPF) at hcpf.colorado.gov. Violations can result in mandatory refunds and civil penalties against the provider.
FAQ
Q: Does Colorado’s medical debt law (HB 1285) protect me from being sent to collections? A: Yes, if you have income below 250% of the federal poverty level. Hospitals must screen you for financial assistance before sending your account to collections or taking legal action. If they did not, contact the Colorado AG’s office.
Q: Can Colorado hospitals charge interest on medical debt? A: Under Colorado’s 2022 medical debt law, hospitals cannot charge interest on debts for patients below certain income thresholds. Ask the billing department to confirm whether interest is being added and whether you qualify for an interest waiver.

Plans sold there are subject to both state and federal protections. Contact DORA for complaints about Connect for Health Colorado plans.
