Colorado workers' compensation — ten days to write, thirty days to object.

Colorado runs on paperwork with teeth. Notice is short and must be written. Your doctor comes off your employer's list. And the most dangerous document in the system is one that arrives looking like good news: the Final Admission of Liability, which closes your case automatically if you don't object in thirty days.

How the Colorado system works

Nearly all Colorado employers must carry coverage, administered by the Division of Workers' Compensation with disputes before the Office of Administrative Courts. Colorado's system moves on formal admissions: the insurer files a General Admission when it accepts the claim and a Final Admission when it thinks the case is done — and each document starts clocks that run whether or not you understand them.

Every deadline that matters

WhatDeadlineWhy it matters
Written notice to your employer10 daysShort and written — a same-day text or email covers it. Late notice can cost benefits for the delay period.
File a Worker's Claim for Compensation2 years (3 with a reasonable excuse)The formal Division filing — voluntary payments don't replace it.
Object to a Final Admission of Liability30 daysColorado's signature trap — miss it and the case closes on the insurer's numbers. Details below.

The Final Admission trap

Thirty days, or it's over

When the insurer files a Final Admission of Liability (FAL), it's stating what it believes your case is worth — impairment rating, benefits, everything — and if you do nothing for 30 days, the case closes automatically on those terms. To keep your claim alive you must file a written objection within 30 days, and if you disagree with the impairment rating, also request a DIME in time. The FAL arrives looking like routine paperwork with a check attached. It is actually the endgame document. Never let one sit.

The designated provider list

Your employer must give you a list of designated medical providers (in most areas at least four, meeting independence rules) — and you choose your treating doctor from that list. You get one change to another listed provider within 90 days of injury, largely on request. If the employer never furnished a proper list in time, the choice of doctor may pass to you — a detail worth checking with the Division, because it flips the most important lever in the claim.

The DIME — Colorado's neutral rating exam

To challenge the treating doctor's impairment rating or MMI finding, Colorado routes you through a Division Independent Medical Examination — a neutral doctor selected through the Division. The DIME's opinion carries heavyweight legal status: it can only be overcome by "clear and convincing evidence." That makes the DIME request — its timing, and preparing your records for it — one of the highest-stakes moves in the system.

The benefits

BenefitWhat it pays
Medical careAll reasonable and necessary treatment through your designated provider — plus mileage.
Temporary Total (TTD)Two-thirds of your average weekly wage within state caps, after a 3-day waiting period (retroactive past two weeks).
Permanent impairmentScheduled awards for extremities; whole-person impairment benefits (age-and-rating formula) for torso, head, and unscheduled injuries.
Disfigurement / death benefitsSeparate awards for visible scarring; survivor and burial benefits.

How Colorado disputes get resolved

  1. 1

    Admissions and objections

    The insurer admits or denies in writing; you object in writing. The paper record is the case.

  2. 2

    DIME when ratings are disputed

    The neutral exam whose findings take clear and convincing evidence to overturn.

  3. 3

    Hearing and appeals

    Administrative law judge hearing, review by the Industrial Claim Appeals Office, then the courts. Settlements need Division or judge approval.

When a lawyer makes sense in Colorado

Any Final Admission you're unsure about (within the 30 days), DIME strategy, low ratings, denied claims, and all settlements. Fees are contingency percentages capped by statute; consultations typically free — and worth it before the FAL clock runs, not after.

Colorado FAQ

Cashing an admitted-benefits check generally isn't the trap — silence is. What closes your case is failing to file a written objection (and a DIME request, if you dispute the rating) within 30 days. If you have any doubt about the rating or future medical care, object first and get a free consultation inside the window.
If a proper designated provider list wasn't furnished in time, the right to select the treating physician may pass to you. Document when and how you asked, pick a doctor you trust, and confirm your position with the Division — it's one of the few moments Colorado hands the medical lever to the worker.
Colorado workers' compensation has generally covered injured workers regardless of status. Report in writing, keep copies of every admission, and use the Division's free customer service for case-specific guidance.
