Adjudication in insurance is the formal process of reviewing, evaluating, and resolving an insurance claim, dispute, or appeal through a legal or administrative procedure. It encompasses everything from an insurer’s internal claim review to external dispute resolution before a state insurance department, administrative hearings before an Administrative Law Judge (ALJ), and, ultimately, civil court litigation.
In the United States, adjudication is a multi-stage framework designed to give policyholders and claimants multiple opportunities to have their claims fairly reviewed before resorting to the courts. Federal laws including the Affordable Care Act (ACA) and ERISA mandate specific internal and external appeal rights for health insurance plans. State insurance departments regulate adjudication processes for property, casualty, life, and disability policies. Workers’ compensation adjudication follows state-specific administrative law systems, often involving dedicated workers’ comp boards or hearing officers.
Understanding adjudication is critical for policyholders, claims professionals, risk managers, attorneys, and healthcare providers across all lines of insurance. This guide covers the complete adjudication framework as it applies in the United States.

Adjudication (Adjud.) — “The formal process of resolving an insurance dispute, claim, or appeal through a legal or administrative procedure.”
Abbreviation: Adjud. | Type: Process | Category: Claims
Core Purpose: Provide a structured, formal mechanism for resolving insurance disputes at multiple levels before courts | Source: NAIC; IRMI; CMS; ACA; ERISA
| Term | Definition |
|---|---|
| Adjudication | Formal process of reviewing and resolving an insurance claim, dispute, or appeal through internal review, administrative procedure, arbitration, or litigation |
| Claim | A policyholder’s or beneficiary’s formal request for the insurer to pay benefits under the policy |
| Denial | Insurer’s formal refusal to pay a claim, in whole or in part; triggers the appeals process |
| Appeal | Formal challenge to an insurer’s claim decision; may be internal (to insurer) or external (to regulator, ALJ, or court) |
| Administrative Law Judge (ALJ) | Independent hearing officer who presides over administrative adjudication proceedings; used in Medicare, workers’ comp, and state DOI proceedings |
| Explanation of Benefits (EOB) | Document issued by insurer (especially health) explaining what was billed, what was paid, what was denied, and why |
| External Review | Independent review of an insurer’s denial by an Independent Review Organization (IRO) outside the insurer; required under ACA for health plans |
| Arbitration | Private dispute resolution before a neutral arbitrator; an alternative to litigation; may be binding or non-binding |
| Bad Faith | Insurer’s unreasonable refusal to pay a valid claim, delay claims processing, or failure to properly investigate; subject to extra-contractual damages |
| ERISA | Employee Retirement Income Security Act; federal law governing employer-sponsored health and benefit plans; sets minimum appeal standards (29 CFR 2560.503-1) |
| CMS | Centers for Medicare & Medicaid Services; federal agency administering Medicare/Medicaid adjudication at the federal level |
In the U.S., insurance adjudication follows a progressive multi-stage framework. Each stage must generally be exhausted before advancing to the next:
1
Claim Submission & Initial Review
Policyholder submits claim; insurer’s claims department reviews coverage, eligibility, and documentation; initial payment or denial issued
2
Internal First-Level Appeal
Claimant challenges denial in writing to insurer; claims review committee or senior adjuster re-examines; new decision issued within required timeframe
3
Internal Second-Level Appeal
If still denied, claimant may file second internal appeal (required for group health plans under ERISA/ACA); independent review within insurer
4
External Review / State DOI Complaint
Independent Review Organization (IRO) or State DOI examines denial; binding on insurer for health plans under ACA; regulatory oversight for other lines
5
Administrative Hearing (ALJ)
Formal hearing before an Administrative Law Judge; used for Medicare appeals, workers’ comp, state licensing/enforcement; both parties present evidence
6
Civil Court Litigation
Breach of contract or bad faith lawsuit in state or federal court; most expensive and time-consuming; last resort after all administrative remedies exhausted
ℹ️ Exhaustion of Remedies: Most insurance laws and ERISA require claimants to exhaust all internal administrative remedies before filing a lawsuit. Failure to complete the internal appeals process may bar a claimant from bringing a civil action. Courts regularly dismiss insurance suits for failure to exhaust internal remedies first.
The first stage of adjudication is the insurer’s own internal claims review. This is the primary process by which most insurance claims are resolved.

Decision (Pay/Deny/Reserve)
| Step | Action | Key Documents |
|---|---|---|
| 1. Intake | Claim received; assigned claim number; claim type and coverage identified | Proof of Loss form, ACORD claim form, policy declarations |
| 2. Eligibility Check | Verify policy in force; confirm claimant is covered; check policy period and premium payment status | Policy declarations page, premium payment records |
| 3. Coverage Review | Confirm claimed event is a covered peril; check exclusions, conditions, endorsements | Full policy form, endorsements, exclusion riders |
| 4. Investigation | Field adjuster inspects loss; medical records reviewed (health/life/disability); police reports obtained; recorded statements taken; independent medical exam (IME) ordered if needed | Adjuster report, IME report, medical records, police report |
| 5. Valuation | Loss amount calculated (ACV, replacement cost, medical bills, lost wages); subrogation rights evaluated | Repair estimates, medical bills, wage records, appraisal |
| 6. Decision | Claim approved (full/partial payment), denied, or reservation of rights letter issued | Payment draft, denial letter with reason codes, reservation of rights letter |
⚠️ Claim Timeframes: Most states set statutory deadlines for insurers to acknowledge claims (typically 10–15 days), begin investigation, and issue payment or denial decisions (typically 30–45 days). Violation of these prompt payment laws can result in penalties, interest on late payments, and regulatory action. Check your state’s DOI for specific timeframes.
If a claim is denied or underpaid, the policyholder or claimant has the right to file an internal appeal with the insurer. Internal appeal rights are a cornerstone of U.S. insurance regulation.
| Element | Requirements (Health/ERISA Plans) | Requirements (P&C / Life) |
|---|---|---|
| Filing Deadline | At least 180 days from denial notice (ACA/ERISA); expedited: within 72 hrs for urgent care | Typically 30–60 days per policy; state law may set minimums |
| Response Time | Pre-service: 15 days · Post-service: 30 days · Urgent/expedited: 72 hours | Typically 30–45 days under state prompt payment laws |
| Reviewer | Must be independent of original decision-maker; clinical reviewer for medical necessity appeals | Senior claims adjuster, claims manager, or designated appeals committee |
| Documents to Submit | Written appeal letter · supporting medical records · physician letters · clinical guidelines · denial letter | Written appeal · repair estimates · expert reports · photos · policy sections referenced |
| Legal Standards | ACA §2719 · ERISA §503 · 29 CFR §2560.503-1 · DOL Claims Procedure Regulations | State insurance code · state DOI fair claims settlement regulations |
| Levels | At least 2 internal appeal levels required for group health plans (ERISA) | Typically 1 level; some carriers offer 2 |
📋 How to Write an Effective Appeal Letter
| Opening | State policyholder name, policy number, claim number, date of denial, and that you are formally appealing the denial |
| Grounds for Appeal | Specifically cite the policy provision, clinical guideline, or regulatory requirement you believe supports coverage |
| Supporting Evidence | List all attached documents: medical records, physician letter, repair estimates, expert opinions, applicable statutes |
| Requested Outcome | Clearly state what you want: full payment, partial payment, reversal of denial |
| Deadline Reference | Note the timeframe in which the insurer must respond per applicable law or policy |
| Contact Information | Name, address, phone, email; request written response |
External Review (Health Insurance)
Under the ACA §2719, all non-grandfathered health insurance plans must provide access to an external review process after exhausting internal appeals. External review is conducted by an Independent Review Organization (IRO) — an organization independent of the insurer, accredited by URAC or NCQA.
| Feature | Standard External Review | Expedited External Review |
|---|---|---|
| When Available | After exhausting internal appeals OR if insurer fails to follow internal appeal timelines | When life or health at serious jeopardy; ongoing treatment being denied; urgent care denial |
| Filing Deadline | Within 4 months of final internal denial | At any time while urgent; no specific deadline in most states |
| Timeframe for IRO Decision | 45 days from receipt of request | 72 hours (or sooner) from receipt |
| IRO Decision Binding? | Yes — insurer must comply with IRO decision | Yes — immediately binding on insurer |
| Cost to Claimant | Up to $25 per request in most states (some states free) | Generally free |
| Administered By | State DOI assigns IRO or ERISA plan’s designated IRO (for self-funded plans: HHS process) | State DOI or HHS |
State Department of Insurance (DOI) Complaints
Any policyholder can file a complaint with their State Department of Insurance (DOI) for any line of insurance — not just health. The DOI investigates complaints involving claim denials, delays, bad faith conduct, and violations of state insurance laws.
| Step | Process |
|---|---|
| 1. File Online | Most state DOIs accept online complaints at their official website (e.g., ca.gov/insurance, dfs.ny.gov) |
| 2. Documentation | Submit policy, denial letters, correspondence, EOBs, estimates, and your written summary of the dispute |
| 3. DOI Review | DOI contacts insurer for response; most complaints resolved within 30–60 days |
| 4. Outcome | DOI may require insurer to reconsider denial, pay claim, explain decision in detail, or face regulatory action |
| 5. Market Conduct | Patterns of complaints trigger market conduct examinations, which can result in fines and consent orders |
✅ NAIC Consumer Resources: The NAIC maintains a nationwide consumer information portal at content.naic.org where consumers can find their state DOI, look up insurer complaint ratios, and access model insurance complaint resources. The NAIC Complaint Database tracks complaint trends across all insurers and states.
An Administrative Law Judge (ALJ) is an independent hearing officer who presides over formal administrative adjudication proceedings. ALJs are used in several insurance contexts in the U.S.:
| Context | ALJ Role | Governing Authority |
|---|---|---|
| Medicare Appeals (Level 3) | Hears appeals after unfavorable QIC (Qualified Independent Contractor) decision; independent of CMS; can award full, partial, or no payment | 42 CFR Part 405; CMS Office of Medicare Hearings and Appeals (OMHA) |
| Medicaid Appeals | State ALJ hears Medicaid beneficiary appeals regarding denials, reductions, terminations of services | 42 CFR Part 431; State Administrative Procedure Acts |
| Workers’ Compensation | State hearing officers / workers’ comp ALJs hear disputes about compensability, medical benefits, permanent disability ratings, return to work | State Workers’ Comp Acts; state workers’ comp boards (e.g., NY WCB, CA DWC) |
| State DOI Enforcement | ALJs preside over insurer license revocation, market conduct enforcement, rate filing disputes, and agent disciplinary proceedings | State Administrative Procedure Acts; State Insurance Codes |
| ERISA Benefits | ALJs at DOL hear certain ERISA fiduciary and plan administration disputes | ERISA §502; DOL Office of Administrative Law Judges |
ALJ Hearing Process
- Request for Hearing: Filed within required timeframe after unfavorable administrative decision (e.g., 60 days for Medicare QIC denials)
- Pre-Hearing: Both parties exchange evidence, witness lists, and written arguments; ALJ may hold pre-hearing conference
- Hearing: Both parties present testimony and evidence; ALJ examines witnesses; no jury; formal rules of evidence may be relaxed
- Post-Hearing Briefs: Parties may submit written arguments summarizing evidence and legal positions
- ALJ Decision: Written decision with findings of fact and conclusions of law; issued within timeframes set by governing rules
- Further Appeal: ALJ decision can be appealed to appeals council (Medicare), state appellate court (workers’ comp), or federal court
ℹ️ Medicare ALJ Backlog: The Medicare ALJ system (OMHA) has historically experienced significant backlogs — often years — particularly for provider appeals of Medicare claim denials. CMS has implemented various settlement programs and process reforms to address this backlog, including the Medicare Appeals Council and Federal District Court options for providers with significant claim volumes.
Health Insurance Claims Adjudication Process
Health insurance adjudication is among the most complex in U.S. insurance, involving medical coding, clinical review, coordination of benefits, and multi-layered federal and state regulations.

ACA Appeal Rights Timeline
| Stage | Timeframe | Authority |
|---|---|---|
| File Internal Appeal | 180 days from denial notice | ACA §2719; ERISA §503 |
| Insurer Response (Pre-service) | 15 days | 29 CFR §2560.503-1 |
| Insurer Response (Post-service) | 30 days | 29 CFR §2560.503-1 |

| IRO Decision (Expedited) | 72 hours | State DOI; HHS |
Property and casualty (P&C) claims adjudication covers homeowners, auto, commercial property, liability, and specialty lines. The adjudication process for P&C differs from health insurance in key respects:
| Feature | P&C Adjudication |
|---|---|
| Primary Method | Field adjuster inspection, estimate negotiation, policy interpretation by claims examiner |
| Key Dispute Issue | Coverage determination (is the loss covered?), Valuation (how much is paid?), Scope of damage (what is included?) |
| Appraisal Process | Most homeowners and commercial property policies include an appraisal clause: each party appoints an appraiser; appraisers agree on an umpire; umpire breaks ties — binding on amount only |
| Mediation | Many states (FL, LA, TX) offer voluntary or mandatory mediation programs for disputed property claims, especially after catastrophic events |
| Public Adjuster | Licensed professional hired by policyholder (not insurer) to manage and negotiate a P&C claim; common in complex or large property claims |
| Prompt Pay Laws | All states have prompt payment statutes; penalties for insurer delay include interest (e.g., 18%/yr in TX), attorney fees, and regulatory fines |
| Suit Limitation | Most P&C policies require suit to be filed within 1–2 years of loss (suit limitation clause); some states void or extend this period |
🏠 P&C Adjudication Example: Homeowner Roof Claim Dispute
| Loss Event | Hailstorm damages roof; homeowner files claim |
| Step 1 | Insurer’s adjuster inspects; issues estimate of $8,000 ACV |
| Step 2 | Homeowner hires public adjuster; counter-estimate of $22,000 RCV |
| Step 3 | Homeowner invokes policy appraisal clause; each party appoints an appraiser |
| Step 4 | Appraisers disagree; appoint umpire; umpire determines $18,000 RCV — binding |
| Step 5 | Insurer pays $18,000 minus deductible and depreciation holdback |
| Alt. Path | If coverage disputed (not just amount), appraisal does not apply; DOI complaint or lawsuit required |
Workers’ compensation (WC) adjudication is governed by state law and administered by state workers’ compensation boards, commissions, or courts. WC is a no-fault system with its own administrative adjudication framework:
| Element | Workers’ Compensation Adjudication |
|---|---|
| Governing Body | State Workers’ Compensation Board, Commission, or Division (e.g., NY Workers’ Compensation Board, CA Division of Workers’ Compensation) |
| Hearing Officers | Workers’ Compensation Judges (WCJs), Hearing Officers, or ALJs specialized in WC law |
| Common Disputes | Compensability (was injury work-related?), Medical benefits (scope of treatment), Temporary/permanent disability rating, Return to work, Attorney fees |
| Process | Claim filed → Insurer accepts or denies → Mediation (in many states) → Formal hearing before WCJ → Board or Commission review → Appellate court |
| Medical Disputes | Independent Medical Examination (IME) ordered to resolve disagreements on disability rating or treatment necessity; IME physician is neutral |
| Utilization Review (UR) | WC insurers conduct UR to approve or deny medical treatment requests; UR denials can be appealed through Independent Medical Review (IMR) in states like CA |
| Settlement | Stipulated Award (ongoing benefits) or Compromise and Release (C&R, lump sum settling all future claims) approved by WC judge |
Medicare and Medicaid adjudication are federal administrative processes governed by CMS. Medicare has the most formalized five-level appeals process in U.S. insurance:
| Level | Body | Timeframe (Expedited) | Timeframe (Standard) |
|---|---|---|---|
| Level 1 — Redetermination | Medicare Administrative Contractor (MAC) | 72 hours (Part A/B inpatient) | 60 days to file; MAC decision in 60 days |
| Level 2 — Reconsideration | Qualified Independent Contractor (QIC) | 72 hours | 180 days to file; QIC decision in 60 days |
| Level 3 — ALJ Hearing | Office of Medicare Hearings and Appeals (OMHA) | Must request within 60 days of QIC denial | ALJ decision within 90 days (target) |
| Level 4 — Appeals Council | Departmental Appeals Board (DAB) Medicare Appeals Council | N/A | 60 days to file; decision in 90 days |
| Level 5 — Federal Court | U.S. District Court | N/A | 60 days to file; amount in controversy threshold required |
✅ Amount in Controversy (AIC) Threshold: To advance to Level 3 (ALJ) Medicare appeals, claimants must meet a minimum Amount in Controversy threshold (adjusted annually by CMS; typically ~$180–$200 for beneficiary appeals; ~$17,000+ for provider appeals to federal court). This limits the ALJ system to disputes of meaningful financial significance.
| Feature | Adjudication (Administrative) | Arbitration | Civil Litigation |
|---|---|---|---|
| Forum | Insurer’s claims dept. → State DOI → ALJ → Appeals Board | Private arbitrator or panel (AAA, JAMS, or policy-specified) | State or federal court; judge or jury |
| Cost | Low (internal) to moderate (DOI/ALJ); often free for consumer | Moderate; filing fees; arbitrator fees; faster than litigation | High — attorney fees, court costs, discovery, expert witnesses |
| Speed | Fastest at internal level; ALJ/DOI: weeks to months | Faster than litigation: weeks to months typically | Slowest: months to years, especially in complex cases |
| Binding? | ALJ decisions: yes · DOI complaints: enforcement through regulatory action, not direct award | Binding if policy/agreement says so; non-binding if agreed | Fully binding; subject to appellate review |
| Discovery | Limited (ALJ) or none (DOI) | Limited formal discovery; may exchange evidence before hearing | Full discovery: depositions, subpoenas, document demands |
| Right to Jury | No | No | Yes (in most cases) |
| Bad Faith Available? | Regulatory penalties only | Generally no (limited to contract damages) | Yes — extra-contractual damages available in bad faith suits |
| Appeal Rights | Yes — administrative appeals board then court | Very limited — courts rarely overturn arbitration awards | Full appellate process |
⚠️ Mandatory Arbitration Clauses: Many insurance policies — particularly commercial policies and some personal auto policies — include mandatory arbitration clauses. Some states (CA, NJ, NY) restrict or regulate mandatory arbitration in consumer insurance policies. Policyholders should review their policy for arbitration provisions before assuming they can pursue litigation directly.
When an insurer fails to adjudicate a claim in a reasonable, good-faith manner, it may be liable for insurance bad faith — a cause of action available in virtually all U.S. states either as a tort or by statute.
❌ Common Bad Faith Conduct
- Unreasonable denial of a valid claim without investigation
- Deliberate delay in claims processing to force settlement
- Failure to communicate claim status to policyholder
- Lowballing claim payments far below actual loss value
- Misrepresenting policy provisions to deny coverage
- Refusing to defend a covered lawsuit (liability claims)
- Failure to settle within policy limits when liability is clear
✅ Remedies for Bad Faith
- Compensatory damages (the unpaid claim amount)
- Consequential damages (foreseeable losses caused by denial)
- Emotional distress damages (first-party bad faith — some states)
- Punitive damages (when conduct is egregious or oppressive)
- Attorney fees and costs
- Regulatory action by state DOI (fines, license suspension)
- Class action suits for systematic bad faith across many policyholders
| Standard | Description |
|---|---|
| First-Party Bad Faith | Insurer fails to pay policyholder’s own claim in good faith (e.g., homeowner’s insurer denies valid property loss) |
| Third-Party Bad Faith | Liability insurer fails to settle within policy limits despite clear liability, exposing insured to excess verdict |
| NAIC Model Unfair Claim Settlement Practices Act | Model law adopted in all 50 states defining unfair claims practices; basis for most state bad faith regulations and enforcement |
| Contractual vs. Tort Bad Faith | Some states allow only contract damages; others (CA, TX, FL) allow full tort recovery including punitive damages for bad faith |
Adjudication in insurance is the formal process of reviewing, evaluating, and resolving an insurance claim, dispute, or appeal through a legal or administrative procedure. It includes the insurer’s internal claim review, external dispute resolution through state insurance departments, administrative hearings before an Administrative Law Judge (ALJ), and civil court litigation.
Adjudication is the broader term covering all formal dispute resolution — administrative, regulatory, and judicial. Litigation specifically refers to the court-based process. In insurance, adjudication typically refers to the insurer’s internal review, state DOI proceedings, and ALJ hearings before reaching full civil court litigation. Most insurance disputes are resolved through administrative adjudication without ever reaching trial.
Health insurance adjudication involves: (1) claim submission by provider or member; (2) eligibility and enrollment verification; (3) medical coding review (ICD-10, CPT); (4) medical necessity review; (5) application of benefits (deductible, copay, coinsurance, COB); (6) payment or denial determination; and (7) issuance of an Explanation of Benefits (EOB). Under the ACA, denied claims trigger mandatory internal and external appeal rights.
An Administrative Law Judge (ALJ) is an independent hearing officer who presides over formal administrative proceedings. In insurance, ALJs are used for Medicare claims appeals (at OMHA — Level 3), Medicaid appeals, workers’ compensation dispute hearings, and state DOI enforcement actions. ALJ hearings are more formal than internal appeals but less formal than civil trials.
To dispute an insurance claim denial: (1) File an Internal Appeal with the insurer within the timeframe in the denial letter; (2) For health insurance, request External Review through the state DOI after exhausting internal appeals; (3) File a complaint with your State Department of Insurance; (4) Consider arbitration if required or available under the policy; (5) Consult an insurance bad faith attorney for civil litigation as a last resort. Document every step and keep copies of all correspondence.
Adjudication encompasses all formal dispute resolution including arbitration. Arbitration is one specific form of adjudication — a private proceeding before a neutral arbitrator rather than a judge or government body. Insurance policies often include mandatory arbitration clauses. Arbitration decisions are generally binding with very limited appeal rights, unlike administrative adjudication decisions which typically have a full appellate chain.
