Colorado Revised Statutes Title 8. Labor and Industry § 8-43-103. Notice of injury--time limit

(1) Notice of an injury, for which compensation and benefits are payable, shall be given by the employer to the division and insurance carrier, unless the employer is self-insured, within ten days after the injury, and, in case of the death of any employee resulting from any such injury or any accident in which three or more employees are injured, the employer shall give immediate notice thereof to the director. If no such notice is given by the employer, as required by articles 40 to 47 of this title, such notice may be given by any person. Any notice required to be filed by an injured employee or, if deceased, by said employee's dependents may be made and filed by anyone on behalf of such claimant and shall be considered as done by such claimant if not specifically disclaimed or objected to by such claimant in writing filed with the division within a reasonable time. Such notice shall be in writing and upon forms prescribed by the division for that purpose and served upon the division by delivering to, or by mailing by registered mail two copies thereof addressed to, the division at its office in Denver, Colorado. Upon receipt of such notice from a claimant, the division shall immediately mail one copy thereof to said employer or said employer's agent or insurance carrier.

(2) The director and administrative law judges employed by the office of administrative courts shall have jurisdiction at all times to hear and determine and make findings and awards on all cases of injury for which compensation or benefits are provided by articles 40 to 47 of this title. Except in cases of disability or death resulting from exposure to radioactive materials, substances, or machines or to fissionable materials, or any type of malignancy caused thereby, or from poisoning by uranium or its compounds, or from asbestosis, silicosis, and anthracosis, the right to compensation and benefits provided by said articles shall be barred unless, within two years after the injury or after death resulting therefrom, a notice claiming compensation is filed with the division. This limitation shall not apply to any claimant to whom compensation has been paid or if it is established to the satisfaction of the director within three years after the injury or death that a reasonable excuse exists for the failure to file such notice claiming compensation and if the employer's rights have not been prejudiced thereby, and the furnishing of medical, surgical, or hospital treatment by the employer shall not be considered payment of compensation or benefits within the meaning of this section;  but, in all cases in which the employer has been given notice of an injury and fails, neglects, or refuses to report said injury to the division as required by the provisions of said articles, this statute of limitations shall not begin to run against the claim of the injured employee or said employee's dependents in the event of death until the required report has been filed with the division.

(3) In cases of disability or death resulting from exposure to radioactive materials, substances, or machines or to fissionable materials, or any type of malignancy caused thereby, or from poisoning by uranium or its compounds, or from asbestosis, silicosis, or anthracosis, the right to compensation and benefits shall be barred unless, within five years after the commencement of disability or death, a notice claiming compensation is filed with the division.
