What to expect and typical timelines

How long for workers comp decision is a common question — this post explains when to expect approval, denial, or a settlement decision and what the typical timelines look like. This article answers the informational question of when the insurance company will approve, deny, or settle a workers’ compensation claim and what factors change that timing.

Below, you’ll find the typical decision windows, a step‑by‑step process map, California‑specific deadlines, common causes of delay, and practical steps to keep your claim moving. Because timelines vary by jurisdiction and case complexity, keep in mind that state rules and the facts of your injury drive the schedule, from first contact to settlement. For example, timelines often hinge on statutory investigation periods and insurer practices like early acknowledgement and outreach to the injured worker, as explained in overviews of state‑driven decision windows and typical adjuster contact practices. If you want a refresher on filing basics, see how to file a workers’ comp claim in California.

Fast overview: Typical workers’ comp decision timeline

A reasonable expected timeline workers comp case for an initial insurer decision is typically a few days to about 90 days after the carrier receives your claim, but complexity and state rules can push that longer.

• First adjuster contact: a few days to 2 weeks after filing, based on common industry practice (initial contact practices).
• Investigation & medical review: often 2–8 weeks depending on records volume and scheduling needs (state timeline overview).
• Straightforward decision (approval/denial): many cases conclude within 2–6 weeks if facts are clear and no specialty exams are required.
• Extended or disputed investigations: up to 60–90 days or more in some jurisdictions, including California (California timelines).

Bottom line: expect anywhere from days (for quick, medical-only claims) to many months (for surgeries, IMEs/QMEs, or disputes). You can revisit filing fundamentals in our guide to what happens after you’re injured on the job in California.

Step‑by‑step timeline breakdown

Below is a practical, step‑by‑step breakdown of the claim lifecycle and how long each stage normally takes.

Employer report and initial filing

This step begins when you inform your employer or the employer learns of your injury and provides the DWC‑1 or state equivalent. The insurer’s timing starts when it receives the completed claim form. In California, employers must generally provide the DWC‑1 within one business day after learning of your injury. See plain‑language guidance on the claim process and employer form obligations and the official California DWC filing page.

Action tips: notify your employer as soon as possible (same day if you can) and keep a dated copy of your injury report or DWC‑1. If you’re just getting started, here’s a refresher on how to file a workers’ comp claim in California.

Insurer initial response window (first 24–72 hours and 1–2 weeks)

Insurers typically acknowledge receipt and send a status letter; adjusters request statements and authorizations. In California, insurers generally have 14 days to mail a status letter indicating acceptance, denial, or that the claim is under investigation (DWC guidance). Many adjusters make first contact within days to two weeks (industry practice).

While investigating, California carriers may authorize up to $10,000 in reasonable medical treatment even before a decision (California investigation and provisional medical). Respond quickly to requests, sign medical releases, and provide treating doctor information.

Investigation phase (evidence gathering, medical records, IMEs/QMEs)

Insurers gather employer reports, medical records, and bills, and may schedule an Independent Medical Exam (IME) or, in California, a Qualified Medical Evaluator (QME) evaluation when causation or disability is disputed. A simple records review can take 2–4 weeks; if an IME/QME is needed, scheduling is often 60–90 days out, and reports can take an additional 30 days or longer in complex cases (IME/QME timing and appeals overview). For lifecycle context, see a plain‑English workers’ comp claim lifecycle explainer.

An IME is a doctor hired by the insurer (used in many states). A QME is California‑specific: a panel evaluator used to resolve disputes about causation, impairment, or work restrictions (timing and process). If you face a QME, learn the basics about QMEs in California and how they affect your claim.

Decision phase: acceptance, denial, or offer to settle

Many states require a decision within 30–90 days of the completed claim; California allows up to 90 days (California decision window). Straightforward claims can be decided in 2–6 weeks; complex cases often use most of the 90 days.

If accepted, medical care is authorized and wage‑loss benefits can begin. In many systems, the first temporary disability check is issued about 14 days after the insurer is notified you cannot work, assuming eligibility and complete documentation (payment timing benchmarks). If denied, you’ll receive written reasons and instructions on appeal. In some cases, insurers make early settlement offers if you’re at or near maximum medical improvement (MMI) (insurer practices, settlement stages).

Post‑decision next steps (benefits start, appeals, settlement negotiations)

If accepted, expect ongoing treatment, periodic disability checks, and later a discussion about settlement or stipulations once you reach MMI (settlement timing). If denied, you may appeal; appeals often add months to a year or more depending on hearings and further medical evaluation (appeals timeline; how long appeals take). For a deeper look at appeals, see our step‑by‑step guide to appealing a denied California workers’ comp claim.

Timeline for claim approval California

California has specific notice and investigation rules that shape the timeline for claim approval.

• Employers must provide a DWC‑1 claim form within one business day after learning of the injury (process overview).
• After you return the form, a status letter is typically mailed within 14 days indicating acceptance, denial, or delay (official DWC page).
• Insurers may authorize up to $10,000 of reasonable medical treatment during investigation, even before acceptance (California investigation rules).
• Insurers have up to 90 days to investigate and decide in many cases (decision window).
• QME evaluations (for medical disputes) can take 60–90 days to schedule, with additional time for reports (QME timing and appeals).

Typical California timeframes:

• Medical‑only claims: usually resolved in weeks to a few months.
• Lost‑time claims: many uncomplicated cases stabilize in 6–9 months.
• Complex injuries or disputed causation: 12–18+ months, especially when QMEs or hearings are involved (decision/settlement timing; appeals/QME timing; hearing/trial info).

Example 1: Simple sprain (no surgery)

• Day 0: Injury at work.
• Day 1: Report to employer; receive and complete DWC‑1.
• By Day 7: Employer/insurer receives claim; you get adjuster outreach.
• By Day 10–14: Status letter (accepted or under investigation); treatment starts (PT/meds).
• Weeks 2–8: Conservative care; return to full duty; case effectively closes with paid medical bills.

Example 2: Surgery (torn meniscus)

• Day 0: Injury; DWC‑1 provided within 1 business day.
• By Day 14: Status letter; investigation continues but up to $10,000 medical authorized.
• Months 1–3: Imaging, conservative care, surgery scheduled/completed.
• Months 6–12: Rehab and MMI; QME may be requested if dispute arises; QME often Month 9–12.
• Months 9–18: Settlement discussions, potential hearing if disputes persist (CA timelines; QME/appeal timing).

Example 3: Occupational disease (e.g., repetitive stress)

• Longer investigation: establishing causation and date of injury can take most of the 90‑day window.
• Multiple specialists and QME: adds months to scheduling/reporting.
• Possible denial and appeal: total 18–24+ months with hearings (appeals/QME; trial info).

Reasons for delay and “settlement decision delay workers comp”

A settlement decision delay workers comp or general claim delay almost always comes down to missing information, disputed causation, or procedural steps like IMEs/QMEs and court scheduling.

• Missing/incomplete medical records: gaps trigger repeat requests and slow reviews.
• Disputes about work‑relatedness: insurers may order additional exams to resolve causation questions.
• IME/QME scheduling and report time: can add 60–150+ days (medical‑legal timing).
• Conflicting medical opinions: may require second opinions or supplemental reports.
• Insurer/provider backlogs: can slow payments and responses (processing delays; investigation limits; adjuster practices).
• Litigation scheduling: conferences, mediations, and hearings extend timelines (appeal durations).

Common warning signs:

• Repeated “under investigation” letters with no next steps.
• Multiple requests for documents you already provided.
• IME/QME appointments pushed out by months.

What you can do:

• Report immediately and keep a copy of the DWC‑1/incident report.
• Sign releases promptly; supply full provider lists and claim numbers.
• Ask the insurer, in writing, to identify outstanding items and estimate a decision date.
• Keep a chronological log of calls, letters, and appointments.
• If statutory limits pass, escalate to a supervisor, consider a board inquiry, or consult an attorney. For settlement timing, see our California‑specific guide to workers’ comp settlements in California.

Insurance response time work injury (what to expect from insurers)

Insurance response time work injury expectations vary by state, but insurers typically must acknowledge claims quickly and issue formal decisions within a defined statutory window.

• Initial contact: typically a few days to 2 weeks (adjuster outreach norms).
• Formal decision window: often 30–90 days; in California, a status letter within 14 days and up to 90 days to decide (DWC filing info; CA timelines).

When to escalate:

• No written status after your state’s acknowledgment period (e.g., 14 days in CA).
• No response to a written inquiry within 7–10 business days.
• Benefits delayed or stopped without explanation.

Whom to contact first: adjuster → claims supervisor → employer HR → state board/ombudsman → attorney. For broader process context, see how to file a workers’ comp claim.

Settlement timeline and expectations

Settlement timelines vary widely, from weeks in simple cases to many months or years for disputed matters; understanding each stage helps set expectations.

• Demand: generally appropriate at or after MMI, once medical status, wage loss, and future care needs are documented.
• Insurer evaluation/counter: review of medical opinions, permanent disability (PD) rating, future care, and vocational factors.
• Negotiation: back‑and‑forth offers; mediation may help resolve valuation disputes (insurer practices).
• Approval and payment: many states require board/judicial approval (e.g., Compromise & Release or Stipulated Award in CA) before payment (approval/payment timing).

Typical timeframes:

• Simple cases: several weeks to a few months from demand to payment (settlement stages).
• Complex/litigated: several months to years, particularly with disputes or appeals (CA timing; investigation practices).
• Post‑approval payment: after any revocation period, many systems pay within ~14 days (payment benchmarks).

When a settlement decision delay workers comp occurs (e.g., additional IMEs, valuation gaps, calendar backlog), consider written status requests, mediation, or in California, filing a Declaration of Readiness to get a settlement conference or hearing scheduled (hearing/appeal timing; WCAB trial info). If you want an overview of how California settlement math works, explore our guide to calculating a California workers’ comp settlement.

If you get a denial: appeals and next steps

A denial starts a different clock—appealing adds procedural steps and often adds many months to the overall timeline. In California, the denial notice generally arrives during the 90‑day investigation window (decision period).

Appeal deadlines vary; some steps must be taken in 20–30 days, and certain board filings can extend longer. Because rules differ, verify your exact deadlines and follow your board’s instructions (appeals overview). From initial reconsideration/mediation through hearing and higher appeals, it’s common for appeals to add many months to 1–2 years or more (appeals duration; hearing process).

Appeal checklist:

• Obtain and review your denial letter; calendar all deadlines.
• Request your complete claim file and medical records formally (keep copies).
• Secure additional medical opinions that link the condition to work (causation).
• Compile witness statements, incident reports, and job records.
• Consider working with an attorney experienced in workers’ comp appeals. For a detailed roadmap, visit our appeals guide.

What to track and documentation checklist

Track these items from day one—accurate dates and organized documents materially speed decisions and strengthen an appeal if needed.

• Injury details: date, time, location, activity, witnesses and contact info.
• Employer report: date/time reported, who you told, copy of DWC‑1/incident form.
• Claim filing: date employer submitted the claim, claim number.
• Adjuster contacts: dates, names, notes from each call/email.
• Medical visits: provider name, date, diagnosis, treatment, prescriptions, work restrictions, next appointment, copies of reports/bills.
• IME/QME: scheduled date, location, examiner name, any delays, report receipt date.
• Payments: dates/amounts of medical payments and wage checks.
• Denials/appeals: copy of denial, date received, appeal deadlines, hearing dates.
• Other evidence: scene photos, incident reports, job logs, payroll records showing lost wages.

Real‑world examples / timelines

Case study 1 — Quick approval (non‑CA)

• Day 0: Injury
• Day 1: Report to employer
• Day 2: Claim filed with insurer
• Day 4: Adjuster contact
• Week 2: Approval and first medical bills paid; off work two weeks with timely wage checks
• Resolution: case wraps in ~2 months

Why it moved fast: immediate reporting and treatment, clear mechanism of injury, and complete records. This is an example of an expected timeline workers comp case with minimal disputes.

Case study 2 — Shoulder surgery, prolonged settlement (California)

• Day 0: Injury; DWC‑1 filed within 3 days
• Day 10: Status letter indicates investigation
• By Day 90: Presumptively accepted; surgery at Month 4
• Month 10: MMI; QME at Month 11; report at Month 12
• Months 12–15: Settlement negotiations
• Month 16: Stipulated Award approved; total ~16 months

Delays came from medical stabilization, QME scheduling, and negotiation. This aligns with typical CA timelines and QME/appeal timing (CA timeframes; QME timing).

Case study 3 — Occupational disease, disputed causation (multi‑state)

• Claim filed years after exposure; denial at ~60 days citing causation
• Month 6: Mediation after appeal filed
• Month 12: Hearing
• Month 14: Decision; limited benefits awarded

Total ~14+ months, driven by medical causation disputes and the appeals calendar (appeals duration). If you face a dispute like this, consider counsel early; see what a workers’ compensation attorney can do to prepare your medical-legal case.

When to get help (attorney, state board, ombudsman)

Get outside help when deadlines are missed, benefits are cut, or the insurer refuses to communicate or offer fair settlement. Clear signals:

• Denial or unexpected benefit cutoff: appeal windows are short; get a second medical-legal opinion if needed.
• Missed statutory windows: no status letter after 14 days or no decision after the 90‑day investigation in California (DWC; state timelines).
• Repeatedly rescheduled IME/QME or stalling: escalate to a supervisor and consider legal counsel.
• Serious injury, surgery, or permanent disability: consult about case value and settlement structure.
