From the moment you get hurt on the job to the moment a settlement check clears, a workers’ comp claim moves through eight distinct stages. Each one has its own paperwork, its own clock, and its own way of going sideways. Here’s what actually happens at every step.
Stage 1 — You report the injury to your employer
The clock starts the second you’re hurt. Every state sets a notice deadline, and they vary a lot: New York gives you 30 days, California gives you 30 days, Florida gives you 30 days, Texas gives you 30 days — but Colorado is 4 working days, Iowa is 90 days, and a handful of states require notice in as little as 24 hours for the carrier to be fully on the hook. Miss the deadline and the carrier has a clean denial.
Notice means written notice. A verbal mention to your foreman rarely holds up. Email your supervisor and HR with the date, time, body part, mechanism of injury, and any witnesses. Keep the sent copy. For the full first-72-hours playbook, see what to do after a work injury.
Stage 2 — Your employer files the First Report of Injury
Once notified, your employer has a short window (usually 5 to 10 days, sometimes faster) to file a First Report of Injury with their workers’ comp carrier and the state agency. The form has different names in different jurisdictions:
- California: DWC-1 claim form goes to the employee, Form 5020 to the state
- Florida: FL-NOI (Notice of Injury), DWC-1
- New York: Form C-2 (Employer’s Report)
- Texas: DWC Form-1
- Illinois: Form 45 (Employer’s First Report)
Once your employer hands you a claim form, fill it out, sign it, and return it the same day. Keep a copy. This is the document that officially puts the carrier on notice. If your employer drags their feet, file the employee version yourself directly with the state — every state allows it.
Stage 3 — The carrier opens a claim and accepts or denies
The carrier now has a statutory window to investigate and decide. Most states give 14 to 30 days; California requires a decision within 90 days, with provisional benefits paid in the meantime. During this window, an adjuster will be assigned, you’ll get a claim number, and the carrier will start ordering medical records and (sometimes) recorded statements.
Three outcomes are possible: accepted (medical and wage benefits flow), delayed (the carrier keeps investigating but starts conditional payments), or denied. If you’re denied, you usually have 30 days to file an appeal or claim petition. See our denial guide — most denials are reversed on appeal, but only if you act inside the window.
Stage 4 — Initial medical treatment
Once the claim is open, the medical channel matters more than anything else. Your first treating physician becomes your primary treating physician (PTP) of record, and the PTP’s opinions shape every later decision: work restrictions, diagnostic approval, surgery authorization, impairment rating.
Where you can go depends on whether your employer uses a Medical Provider Network (MPN) and what state you’re in. Employer-choice states (CA in most cases, PA for 90 days, MA, NJ) channel you through the MPN. Employee-choice states (FL after first visit, NY, IL, TX outside networks) let you pick. Get the rules straight in our doctor-choice guide and MPN explainer. To find a WC-credentialed provider, search our directory by state and specialty.
Stage 5 — Ongoing treatment and temporary disability
While you treat, two parallel processes run. On the medical side, every imaging study, specialist referral, injection, and surgery has to be pre-authorized through utilization review (UR). Denials at UR are common and appealable — in California through Independent Medical Review (IMR), elsewhere through state board hearings.
On the wage side, if your doctor takes you off work, the carrier owes you Temporary Total Disability (TTD). The formula is roughly two-thirds of your average weekly wage, tax-free, capped at a state-specific maximum. In 2026, the weekly cap is about $1,680 in California, $1,255 in New York, $1,260 in Florida, and $1,205 in Texas. If you can do modified or part-time work, you get Temporary Partial Disability (TPD) making up two-thirds of the wage gap. See how much workers’ comp pays for the full breakdown.
Stage 6 — Maximum Medical Improvement and impairment rating
At some point — weeks for a sprain, a year-plus for a spine injury — you stop getting better. That moment is called Maximum Medical Improvement (MMI). MMI doesn’t mean you’re “healed.” It means further treatment won’t materially improve your condition.
Once your PTP declares MMI, they (or a qualified medical examiner) assign an impairment rating using the AMA Guides (5th or 6th edition depending on the state). The rating is a whole-person or body-part percentage — e.g., 12% lumbar spine, 8% upper extremity — and it’s the single biggest driver of your permanent disability payout.
If the carrier’s doctor undershoots you, you can request a second opinion or a Qualified Medical Evaluator (QME)/Agreed Medical Evaluator (AME) exam. Disputed ratings are the most common reason claims drag past the two-year mark.
Stage 7 — Permanent disability determination
The impairment rating converts to dollars through a state-specific Permanent Disability (PD) schedule. In California, a 12% PD rating pays about 35 weeks at your PD rate. In New York, a Schedule Loss of Use award for a knee injury pays a fixed number of weeks per percentage point. In Florida, impairment income benefits run for two weeks per percentage point under 11%, then more above.
If you can’t return to your prior job at all, you may qualify for Permanent Total Disability (PTD), which in some states pays for life. If you can return at reduced earning capacity, you may qualify for supplemental job displacement vouchers (CA) or vocational rehabilitation benefits.
Stage 8 — Settlement
Most claims resolve through settlement rather than a final hearing. Two settlement structures dominate:
- Compromise & Release (C&R). A lump sum that closes the claim — future medical, future indemnity, everything. Faster and cleaner, but you take on all future medical cost. Common when you have group health insurance or are nearing Medicare eligibility (which triggers a Medicare Set-Aside).
- Stipulated Award (Stips / Stip with Request for Award). Pays the PD over time and leaves future medical open. Slower payments, but the carrier keeps paying for injury-related treatment for life in many states.
Settlement amounts depend on your PD rating, your average weekly wage, projected future medical, projected future wage loss, and how much the carrier wants the claim closed. For ranges and what drives them, see our settlement guide.
Where it can go off the rails
Every stage has a failure mode. Notice missed in Stage 1. Carrier denies in Stage 3. UR refuses surgery in Stage 5. Impairment rating disputed in Stage 6. Settlement offered for a fraction of value in Stage 8. The decision points where a workers’ comp attorney moves the needle most are denial appeals, QME/AME disputes, and settlement negotiation. Most states cap attorney fees at 10–25% of the recovery (15% in CA, 20% in FL, 20% in NY), paid out of the award — not out of pocket.
What rights you have through all eight stages
Independent of where you are in the process, you carry a set of rights through the entire claim — choice of doctor within the rules, free medical care, wage replacement, second opinions, settlement on fair terms.
