Claims adjusting in the Colorado workers’ compensation system requires extensive knowledge of and compliance with all statute and rule requirements governing the handling of claims. It is the first point at which the facts of a claim are reviewed in light of thresholds established by law. Reviewing all available information, the adjuster must timely state a position and either assign liability to its insurer, or deny liability for the payment of benefits in the first instance.

Adjuster's Guide

The Adjuster’s Guide was developed by the Division of Workers' Compensation as an informational tool for claims adjusting in Colorado. Generally, the information pertains to claims with dates of injury on or after July 1, 1991, when significant reform legislation was signed into law. The Workers’ Compensation Act of Colorado can be accessed through our website or a copy may be obtained from Customer Service. If this Guide does not answer a specific question or if you would like to schedule tailored training to meet the specific needs of your organization, contact us at 303-318-8700.

Benefit Calculator

These calculators can assist you through the claims adjustment process. 

A brand new PPD Indemnity calculation tab is now available on the Workers’ Compensation Benefits Calculator. This is a much simpler way to calculate both scheduled and whole person ratings. It also identifies Minor claims and automatically changes TTD rates in the calculation, reducing potential errors in admission filings.

Injured Worker Exit Survey

In an effort to determine an injured worker’s satisfaction with the handling of his or her claim, insurers are required to conduct a survey within 30 days after a claim is closed. The survey asks injured workers to respond to questions on courtesy, promptness of medical care, promptness of handling and resolving the claim, as well as overall satisfaction with the insurer.

Injured workers are asked to grade the insurer on a scale of 1 to 5, with 1 being the least satisfied and 5 being the most satisfied. For survey requirements, see Rule 5-14>
