Level I accreditation program is designed to assist in understanding the administrative, legal and medical role in the Colorado Workers’ Compensation system for all medical providers.

Level II accreditation teaches participants how to perform impairment ratings using the AMA Guides to the Evaluation of Permanent Impairment, 3rd Edition (revised). Both levels of accreditation spans for three years and must be renewed every three years.

Level I accreditation includes licensed chiropractors, dentists, podiatrists, physician assistants, nurse practitioners, MDs, and DOs.

Level II accreditation is for licensed MDs and DOs who would like to perform impairment ratings for injured workers. Please refer to the following links for Level I Accreditation and Level II Accreditation

All medical providers benefit from accreditation by expanding their practice and partnering with medical providers or networks. Accreditation also educates providers of all aspects of the workers’ compensation system.
Chiropractors who are Level I accredited are assured of payment for treating workers' compensation patients beyond ninety days after the first treatment, or in excess of twelve treatments, whichever occurs first.

Physicians who are Level II Accredited can extend their practice to determine impairment ratings for injured workers and conduct independent medical examinations that include calculating impairment ratings.

In order for providers to become members in some insurance networks, the insurer may require medical providers to be trained by the Division through the Level I Accreditation course. Not only will the medical provider obtain necessary information for treating in the workers’ compensation system, but the provider will be placed on a “Division trained” list on our website.

No, Colorado law requires that only licensed physicians with Level II accreditation may provide impairment ratings of injured workers. C.R.S. 8-42-101 (3.6)(b). This includes only licensed medical doctors and doctors of osteopathy.

No, but if an impairment rating is needed for the IME, it must be referred to a Level II Accredited physician.

The Division’s Independent Medical Examination Program (DIME)  program provides an independent review of workers’ compensation cases in which their is a dispute concerning an injured worker’s date of maximum medical improvement or an impairment rating. Because impairment ratings are involved, only Level II-accredited physicians may participate on the IME panel of physicians.

Some of the benefits of becoming a physician on the DIME panel include: elevating your status as an expert for performing IMEs, serving the citizens of Colorado by protecting the integrity of the workers’ compensation system and reducing litigation costs for employers and injured workers, and the ability to serve on the task force for the Medical Treatment Guidelines.

The purpose of the Utilization Review program is to provide a mechanism to review and remedy services that may not be reasonably necessary or reasonably appropriate according to professional standards. Section 8-43-501 of the Colorado Revised Statutes governs utilization review and Colorado Division of Workers’ Compensation Rule 10. A Utilization Review on a case is performed by a panel of Colorado licensed medical providers. The panel is convened by the Division to conduct a “paper” review of the case and evaluate the services provided. The outcome of such proceedings may require a change of provider in that case, no change of provider, retroactive denial of fees, and/or revocation of accreditation (if applicable).
