Filing a Healthcare Complaint or Grievance: Step-by-Step
Patients and enrollees in the United States have structured, federally-backed mechanisms for challenging decisions made by health insurers, hospitals, and other providers. This page maps the formal complaint and grievance process — including who accepts filings, what distinguishes a grievance from an appeal, and how federal and state oversight agencies interact with those submissions. Understanding these pathways is foundational to exercising patient rights and responsibilities effectively.
Definition and scope
A grievance is a formal expression of dissatisfaction about a health plan, provider, or facility that does not involve a request to overturn a coverage denial. An appeal is a specific request to reverse an adverse benefit determination — such as a prior authorization denial, a claim denial, or a termination of services. The two mechanisms are related but procedurally distinct, and filing the wrong type can delay resolution.
The regulatory framework governing these processes spans multiple federal authorities:
- The Employee Retirement Income Security Act (ERISA), administered by the U.S. Department of Labor, governs employer-sponsored health plans and mandates internal and external appeal rights (DOL ERISA overview).
- The Affordable Care Act (ACA) expanded and standardized appeal rights for non-grandfathered health plans under 45 C.F.R. Part 147 (HHS ACA regulations).
- Centers for Medicare & Medicaid Services (CMS) sets grievance and appeal standards for Medicare Advantage plans under 42 C.F.R. §§ 422.561–422.626 and for Medicaid managed care under 42 C.F.R. Part 438 (CMS Managed Care regulations).
- The Joint Commission accredits hospitals and requires a documented grievance process as part of its Patient Rights standards (CAMH standard RI.01.07.01) (The Joint Commission).
State insurance commissioners add a third layer, accepting complaints against licensed insurers operating within their jurisdictions.
How it works
The process follows a structured sequence. Deviating from the order — particularly by skipping internal review — can forfeit external appeal rights under ERISA and ACA rules.
- Identify the correct channel. Determine whether the issue involves a coverage decision (use the appeals track), a quality-of-care or service complaint (use the grievance track), or a privacy violation (file separately under HIPAA patient privacy rights).
- File an internal grievance or appeal. Submit in writing to the health plan or facility. Non-grandfathered ACA-compliant plans must acknowledge receipt and issue a decision within 30 days for pre-service appeals and 60 days for post-service appeals, per 45 C.F.R. § 147.136.
- Request an expedited review if clinically urgent. Plans must respond to expedited internal appeals within 72 hours under 45 C.F.R. § 147.136(b)(2)(i).
- Escalate to external review. If the internal appeal is denied, enrollees in ACA-compliant plans have the right to independent external review. The external reviewer's decision is binding on the plan. CMS maintains a list of federally-approved Independent Review Organizations (IROs).
- File with a regulatory body. Simultaneously or following exhaustion of plan-level remedies, complaints may be filed with the applicable state insurance commissioner, CMS (for Medicare/Medicaid), or the DOL's Employee Benefits Security Administration (EBSA) for ERISA plans (EBSA complaint portal).
- Escalate to accreditation bodies. Complaints about hospital care quality can be submitted to The Joint Commission through its Office of Quality and Patient Safety.
For Medicare beneficiaries, the Quality Improvement Organization (QIO) program — managed under CMS — handles hospital discharge disputes and quality-of-care complaints with specific statutory timelines.
Common scenarios
Three filing scenarios account for the majority of formal healthcare complaint submissions:
Scenario A — Coverage denial. A health plan issues an Explanation of Benefits (EOB) indicating a service was denied as not medically necessary. The enrollee pursues the internal appeals process, then external review if needed. Surprise billing disputes have a parallel but separate pathway under the No Surprises Act, codified at 45 C.F.R. Part 149 (surprise medical billing protections).
Scenario B — Quality-of-care complaint. A patient believes care received at a hospital was substandard. This is filed as a grievance with the hospital's patient relations office and, if unresolved, with the state's health department survey agency or the applicable CMS-certified QIO. The Joint Commission complaint process is a parallel option for accredited facilities.
Scenario C — Billing dispute. A patient receives a bill that does not match the medical billing and coding submitted to the insurer. Disputes of this type are often resolved through the plan's grievance process, the state insurance commissioner, or — for federal program participants — the relevant CMS contractor.
For patients managing ongoing conditions, care coordination and case management services may assist with grievance navigation as a covered benefit under some plans.
Decision boundaries
Not every complaint fits neatly into a single channel. The decision boundaries below clarify which path applies:
| Situation | Correct Path |
|---|---|
| Denial of a specific service or drug | Internal appeal → external IRO review |
| Dissatisfaction with provider behavior | Grievance to plan or facility + state medical board |
| Billing error or balance bill | Plan grievance + state insurance commissioner |
| Privacy breach or records access denial | HIPAA complaint to HHS Office for Civil Rights (OCR complaint portal) |
| Discrimination in care delivery | ADA/Section 1557 complaint to HHS OCR |
| Medicare claim dispute | Medicare Administrative Contractor (MAC) → ALJ → Medicare Appeals Council |
Patients covered by Medicaid managed care should note that 42 C.F.R. § 438.400 defines "grievance" and "appeal" differently than the commercial plan context — a distinction that affects filing deadlines and decision timelines. Medicaid eligibility and enrollment documentation will identify the relevant managed care plan and its specific grievance coordinator.
For individuals dealing with hospital charges after a stay, medical debt and collections patient rights covers the distinct framework governing debt collection conduct — a separate process from the insurance appeal pathway.
Patient advocacy services organizations, including hospital-based patient advocates and independent nonprofits, can assist in preparing complaint submissions without constituting legal representation.
