How to File a Complaint Against UnitedHealthcare: State, DOL, CMS, and Attorney General
Learn how to file complaints against UHC with your state insurance department, DOL EBSA for ERISA plans, CMS for Medicare Advantage, and state attorney general offices.
How to File a Complaint Against UnitedHealthcare: State, DOL, CMS, and Attorney General
When UnitedHealthcare denies your claim, limits your benefits, or handles your case improperly, an internal appeal is often the right first move. But complaints to regulatory agencies — filed simultaneously with or after appeals — can be powerful tools for accelerating resolution and protecting your rights. This guide covers every complaint channel available to UHC members.
Why File a Regulatory Complaint?
Regulatory complaints serve multiple purposes beyond your individual case:
- They create a formal record of UHC's conduct that regulators track
- They can prompt direct contact from the regulator to UHC, often speeding up your case
- They contribute to patterns that can trigger regulatory investigations or enforcement
- For ERISA plans, DOL complaints can result in agency intervention on your behalf
- For Medicare Advantage, CMS complaints can trigger plan audits and corrective actions
Filing a complaint does not waive your appeal rights. You can and should file complaints while also pursuing UHC's internal appeals process.
1. State Insurance Department Complaints
Who this applies to: Members with fully-insured state-regulated plans — individual and family plans (including ACA marketplace plans) and fully-insured small and large group employer plans.
Who this does NOT apply to: Members in self-funded ERISA employer plans. If your employer self-funds its health plan (even if UHC administers it), your state insurance department typically does not have jurisdiction over claim disputes. However, you can still contact them about issues related to UHC's licensed insurance operations in your state.
How to file: Go to your state insurance department's website and look for the consumer complaint portal. Every state has an online complaint form. You can also call your state insurance commissioner's office. The NAIC (National Association of Insurance Commissioners) website at naic.org/consumer has links to every state's complaint portal.
What to include: Your member ID, policy number, the specific claim or coverage denied, the date of denial, the reason UHC provided, what you are requesting, and copies of all relevant correspondence (denial letters, appeal letters, UHC responses).
What happens: The state insurance department contacts UHC and requests a formal response within a specified timeframe (often 15 to 45 days). UHC must explain its position to regulators. Many complaints result in UHC reversing its denial or agreeing to reconsider once it knows regulators are watching.
Key state agencies for large UHC markets:
- California: Department of Managed Health Care (DMHC) — dmhc.ca.gov — 888-466-2219; also CA Department of Insurance (CDI)
- New York: Department of Financial Services (DFS) — dfs.ny.gov
- Texas: Texas Department of Insurance (TDI) — tdi.texas.gov
- Florida: Office of Insurance Regulation (OIR) — floir.com
- Illinois: Department of Insurance (IDOI) — insurance.illinois.gov
2. DOL EBSA Complaint (ERISA Plans)
Who this applies to: Members in ERISA-governed employer health plans — this covers the majority of working Americans with employer-sponsored insurance. If your employer sponsors your health plan (even if you are a large company employee), it is almost certainly an ERISA plan.
How to file: Online at askebsa.dol.gov or by calling 1-866-444-EBSA (3272). The EBSA (Employee Benefits Security Administration) is the DOL division that enforces ERISA.
What EBSA can do:
- Investigate whether UHC (as the plan administrator) followed required ERISA claims procedures
- Require plan administrators to comply with ERISA's claims and appeals regulations
- Investigate violations of Mental Health Parity Act (MHPAEA) Explained" class="auto-link">MHPAEA (Mental Health Parity) — EBSA is the primary federal enforcer of MHPAEA for ERISA plans
- Take enforcement action against employers and plan administrators for ERISA violations
What EBSA cannot do: EBSA cannot adjudicate individual benefit disputes or order UHC to pay your specific claim. However, EBSA's involvement often results in UHC reviewing your case more carefully and improving its procedures.
For MHPAEA complaints specifically: If you believe UHC or Optum applied more restrictive criteria to your mental health or substance use disorder claim than to comparable medical/surgical benefits, EBSA is the primary enforcement agency. File a detailed MHPAEA complaint describing the disparity you experienced and requesting the NQTL comparative analysis from UHC.
3. CMS Complaint (Medicare Advantage Plans)
Who this applies to: UHC Medicare Advantage (MA) plan members. UHC is the largest Medicare Advantage insurer in the country.

What CMS can do:
- Investigate whether UHC's MA plan is complying with CMS regulations for coverage and appeals
- Require UHC to respond to member complaints
- Audit UHC's MA plan for coverage denial patterns
- Issue sanctions against MA plans that persistently violate CMS regulations (including financial penalties)
- Refer quality-of-care issues to the Quality Improvement Organization (QIO)
CMS has taken enforcement action against UHC's Medicare Advantage plans in the past for Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization violations and untimely appeals responses. Your complaint contributes to the data CMS uses for oversight.
Medicare Quality Improvement Organization (QIO): For inpatient care issues — including inappropriate discharge pressure — contact your state's QIO directly. QIOs can conduct immediate reviews of inpatient care decisions. Find your QIO at qioprogram.org.
4. State Attorney General Complaints
Who this applies to: All UHC members, particularly for cases involving unfair or deceptive trade practices, fraud, or systematic denial patterns.
When to use: If you believe UHC's denial practices are deceptive, if UHC misrepresented your benefits, or if you are aware of a systematic pattern of improper denials that may affect many members.
How to file: Go to your state attorney general's website and look for the consumer protection complaint portal. Most AGs have online complaint forms.
What AGs can do: AGs enforce state consumer protection laws, unfair trade practice statutes, and in some states, specific insurance fraud statutes. While AG complaints are less commonly used for individual benefit disputes, they are appropriate when UHC's conduct rises to the level of deceptive or fraudulent practices. AG investigations can result in state-level enforcement actions.
5. CMS No Surprises Help Desk
For No Surprises Act violations: If UHC applied out-of-network cost-sharing to emergency care or to services from OON providers at in-network facilities where the NSA protections should apply, file with the No Surprises Help Desk at cms.gov/nosurprises or call 1-800-985-3059.
6. Office of Civil Rights (OCR) – Discrimination Complaints
When to use: If you believe UHC denied your claim or provided inferior coverage based on a protected characteristic (race, sex, national origin, disability, age) in violation of civil rights laws including Section 1557 of the ACA and other federal anti-discrimination statutes.
How to file: Online at hhs.gov/ocr/complaints or by calling 1-800-368-1019.
Coordinating Complaints and Appeals
File your regulatory complaint at the same time as your internal appeal with UHC. You do not need to wait for UHC's internal appeal process to conclude before filing a complaint. Many complaints to state insurance departments or EBSA result in UHC reviewing the case more carefully during the internal appeal process, increasing your chances of a favorable outcome.
Keep records of all complaint submissions: case numbers from regulatory agencies, dates of filing, and any responses you receive.
