In a dispute in a workers' compensation claim, current law requires
a claimant to prove, by a preponderance of the evidence, the claimant's
entitlement to medical benefits. When the dispute concerns whether the
medical treatment recommended by an authorized treating physician is
reasonable, necessary, and related to the claimant's injury, the bill shifts
the burden of proof from the claimant to the claimant's employer or the
employer's workers' compensation insurer.
The bill provides injured workers control over the selection of
their primary treating physician in workers' compensation cases, allowing
them to choose from any level I or level II accredited physician through
the division of workers' compensation. The bill creates the mechanism by
which an injured worker may select the treating physician and requires
the employer or insurer to choose the physician when an injured worker
is unable or unwilling to select the treating physician.
Be it enacted by the General Assembly of the State of Colorado:1
SECTION 1. Legislative declaration. (1)  The general assembly2
finds that:3
(a)  Without workers, no products are made, no meals are served,4
no goods are transported, no ski areas operate, no medical care is5
provided, no fires are fought, and no highways stay safe. Workers are the6
backbone of Colorado. When a worker is hurt, Colorado's backbone is7
weakened.8
(b)  Colorado's workers' compensation act, referred to in this9
section as the "workers' act", was enacted in 1915, and it opens with an10
unequivocal declaration of intent that can be summarized as assuring the11
quick and efficient delivery of disability and medical benefits to injured12
workers at a reasonable cost, without the necessity of litigation;13
(c)  In 1991, Colorado Senate Bill 91-218 drastically altered the14
workers' compensation system, undermining the intent of the workers' act15
set forth by the general assembly in 1915. Thirty-four years after those16
HB25-1300-2- amendments, we still have a workers' compensation system weighted1
heavily against injured workers and in favor of insurance companies, as2
evidenced by:3
(I)  Injured workers in Colorado lack basic agency to choose who4
treats their injuries. When a worker is hurt on the job, the employer and5
its insurer have control over the primary doctor assigned. Once a primary6
physician is assigned, that physician's referrals to other medical7
specialists and therapists are also subject to denial by employers and their8
insurers.9
(II)  Even after an employer and insurer direct a worker to seek10
treatment with a specific physician or physicians, they can deny the11
medical care that a physician recommends as unreasonable or12
unnecessary. When such a dispute arises, it is the worker who bears the13
burden of proof in court.14
(III)  While employers and insurers are directed to follow the15
state's utilization standards in making determinations regarding the16
authorization or denial of medical care, they often fail to do so. When17
they do fail, there is no expeditious recourse for workers. The division of18
workers' compensation in the department of labor and employment does19
not have clear authority to rule on issues surrounding an employer or their20
insurer's violation of the utilization standards.21
(IV)  Workers whose injuries are severe enough to lead to wage22
loss or permanent impairment, or both, are limited in recovering their23
economic losses by arbitrary benefit caps. Those caps most significantly24
and wrongfully impact workers whose injuries are severe.25
(V)  Benefits payable to injured workers for permanent impairment26
are paid unequally. While some permanent disabilities are paid through27
HB25-1300
-3- a holistic lens based on the permanency of the workers' symptoms, lost1
income, and an inability to work or complete activities of daily living,2
others are paid according to an arbitrary schedule of benefits. The3
schedule of benefits almost always results in less compensation for4
injured workers, even in instances of severe disability.5
(VI)  Injured workers who are entitled to permanent impairment6
benefits must wait months or even years to fully collect their award. By7
default, employers and their insurers are allowed to pay those benefits8
over time, and if a worker wants the benefit paid in full without delay,9
they must pay a discount charge to the insurer.10
(VII)  Workers who are the most severely injured and therefore11
unable to return to similar or "suitable" employment following an12
industrial injury are not owed any additional monetary benefit under the13
current scheme. Since the 1991 changes to the workers' act, to obtain14
permanent total disability in Colorado, a worker must be "unable to earn15
any wage". This standard has rendered permanent total disability benefits16
nearly obsolete.17
(VIII)  Despite the fact that an injured worker is the first-party18
insured of their employer's workers' compensation insurer, meaning that19
the insurer is prohibited from the unreasonable delay or denial of benefits,20
workers do not have access to the normal statutory remedies available for21
the unfair claims handling practices of a workers' compensation insurer.22
This emboldens Colorado workers' compensation insurers to engage in23
deceptive, unfair, unreasonable, and frivolous practices in the handling24
of claims.25
(IX)  All workers deserve the best care when injured. The state of26
Colorado, as an employer, should make every effort to obtain workers'27
HB25-1300
-4- compensation coverage with the worker experience in mind. Pinnacol is1
the top-rated workers' compensation insurer by workers and is already a2
quasi-state agency. The state should contract with Pinnacol for coverage,3
rather than other third parties, many of which are out-of-state entities4
without a connection to Colorado and are not subject to the same5
transparency and financial disclosure requirements as Pinnacol.6
(d)  In contrast to the hardships faced by injured workers since7
1991, Colorado's workers' compensation insurers are enjoying8
unprecedented economic success, posting profit margins higher than any9
other type of insurance in Colorado.10
(2)  The general assembly declares that:11
(a)  The playing field must be leveled and the workers' act must be12
returned to a mechanism with the functionality of its original intent; and13
(b)  With this act, the state of Colorado hopes to alleviate a portion14
of the inequities set forth in this section but acknowledges that additional15
change must be made in the coming years.16

claimant is entitled to medical maintenance benefits recommended by an7
