Hurt at Work in Colorado? Ten Working Days Changes Everything

Ten working days: the notice rule

Colorado requires written notice of a work injury to your employer within 10 working days (C.R.S. 8-43-102). Late notice can cost you benefits. Separately, a Worker's Claim for Compensation (WC15) is generally filed with the Division of Workers' Compensation within two years. Report first, in writing, even if the injury seems minor — many serious claims start as 'I thought it would get better.'

What comp pays — and who picks the doctor

Colorado comp covers medical treatment, a portion of lost wages while you recover, and permanent impairment benefits when an injury leaves lasting damage — generally regardless of fault. One catch: the employer generally designates the treating physicians, at least initially. Impairment ratings can be challenged, including through an independent medical examination, and the rating drives what a serious claim is worth. Start at the Colorado work injury hub.

Denied? The hearing path

Denials are common — 'not work-related,' late notice, pre-existing conditions. Disputed claims are heard through the Division of Workers' Compensation and the Office of Administrative Courts, with strict deadlines at each step. Many denials are challenged successfully; missing a deadline usually isn't. Start at the denied claims hub.

Resorts, rigs, and third parties

Colorado's signature industries add wrinkles. Ski resort workers — lift ops, instructors, patrol, lodge staff — are generally covered like any employee, seasonal or not (see the resort worker hub). In the DJ Basin oilfields, multiple companies share every well site, so third-party lawsuits often exist alongside comp (see the oilfield hub). Comp is generally the exclusive remedy against your employer — but never against the negligent third party.
