(a) The Workers' Compensation Commission, and effective upon termination of the commission, the Insurance Commissioner, shall establish and alter from time to time, as it determines appropriate, a schedule of the maximum reasonable amounts to be paid to health care providers, providers of rehabilitation services, providers of durable medical and other goods and providers of other supplies and medically related items or other persons, firms or corporations for the rendering of treatment or services to injured employees under this chapter. The commission and effective upon termination of the commission, the Insurance Commissioner, also, on the first day of each regular session and also from time to time, as it may consider appropriate, shall submit the schedule, with any changes thereto, to the Legislature.

The commission, and effective upon termination of the commission, all private carriers and self-insured employers or their agents, shall disburse and pay for personal injuries to the employees who are entitled to the benefits under this chapter as follows:

(1) Sums for health care services, rehabilitation services, durable medical and other goods and other supplies and medically related items as may be reasonably required. The commission, and effective upon termination of the commission, all private carriers and self-insured employers or their agents, shall determine that which is reasonably required within the meaning of this section in accordance with the guidelines developed by the health care advisory panel pursuant to section three-b of this article: Provided, That nothing in this section shall prevent the implementation of guidelines applicable to a particular type of treatment or service or to a particular type of injury before guidelines have been developed for other types of treatment or services or injuries: Provided, however, That any guidelines for utilization review which are developed in addition to the guidelines provided for in section three-b of this article may be used by the commission, and effective upon termination of the commission, all private carriers and self-insured employers or their agents, until superseded by guidelines developed by the health care advisory panel pursuant to said section. Each health care provider who seeks to provide services or treatment which are not within any guideline shall submit to the commission, and effective upon termination of the commission, all private carriers, self-insured employers and other payors, specific justification for the need for the additional services in the particular case and the commission shall have the justification reviewed by a health care professional before authorizing the additional services. The commission, and effective upon termination of the commission, all private carriers, self-insured employers and other payors, may enter into preferred provider and managed care agreements which provides for fees and other payments which deviate from the schedule set forth in this subsection.
(2) Payment for health care services, rehabilitation services, durable medical and other goods and other supplies and medically related items authorized under this subsection may be made to the injured employee or to the person, firm or corporation who or which has rendered the treatment or furnished health care services, rehabilitation services, durable medical or other goods or other supplies and items, or who has advanced payment for them, as the commission, and effective upon termination of the commission, all private carriers, self-insured employers and other payors, considers proper, but no payments or disbursements shall be made or awarded by the commission unless duly verified statements on forms prescribed by the commission, and effective upon termination of the commission, all private carriers, self-insured employers and other payors, have been filed within six months after the rendering of the treatment or the delivery of such goods, supplies or items or within ninety days of a subsequent compensability ruling if a claim is initially rejected: Provided, That no payment under this section shall be made unless a verified statement shows no charge for or with respect to the treatment or for or with respect to any of the items specified in this subdivision has been or will be made against the injured employee or any other person, firm or corporation. When an employee covered under the provisions of this chapter is injured, in the course of and as a result of his or her employment and is accepted for health care services, rehabilitation services, or the provision of durable medical or other goods or other supplies or medically related items, the person, firm or corporation rendering the treatment may not make any charge or charges for the treatment or with respect to the treatment against the injured employee or any other person, firm or corporation which would result in a total charge for the treatment rendered in excess of the maximum amount set forth therefor in the commission schedule set forth in this subsection.
(3) Any pharmacist filling a prescription for medication for a workers' compensation claimant shall dispense a generic brand of the prescribed medication if a generic brand exists. If a generic brand does not exist, the pharmacist may dispense the name brand. In the event that a claimant wishes to receive the name brand medication in lieu of the generic brand, the claimant may receive the name brand medication but, in that event, the claimant is personally liable for the difference in costs between the generic brand medication and the brand name medication.
(4) In the event that a claimant elects to receive health care services from a health care provider from outside of the state of West Virginia and if that health care provider refuses to abide by and accept as full payment the reimbursement made by the Workers' Compensation Commission, and effective upon termination of the commission, all private carriers and self-insured employers or their agents, pursuant to the schedule of maximum reasonable amounts of fees authorized by this subsection, with the exceptions noted below, the claimant is personally liable for the difference between the scheduled fee and the amount demanded by the out-of-state health care provider.
(A) In the event of an emergency where there is an urgent need for immediate medical attention in order to prevent the death of a claimant or to prevent serious and permanent harm to the claimant, if the claimant receives the emergency care from an out-of-state health care provider who refuses to accept as full payment the scheduled amount, the claimant is not personally liable for the difference between the amount scheduled and the amount demanded by the health care provider. Upon the claimant's attaining a stable medical condition and being able to be transferred to either a West Virginia health care provider or an out-of-state health care provider who has agreed to accept the scheduled amount of fees as payment in full, if the claimant refuses to seek the specified alternative health care providers, he or she is personally liable for the difference in costs between the scheduled amount and the amount demanded by the health care provider for services provided after attaining stability and being able to be transferred.
(B) In the event that there is no health care provider reasonably near to the claimant's home who is qualified to provide the claimant's needed medical services who is either located in the state of West Virginia or who has agreed to accept as payment in full the scheduled amounts of fees, the commission, upon application by the claimant, may authorize the claimant to receive medical services from another health care provider. The claimant is not personally liable for the difference in costs between the scheduled amount and the amount demanded by the health care provider.
(b)
(1) No employer shall enter into any contracts with any hospital, its physicians, officers, agents or employees to render medical, dental or hospital service or to give medical or surgical attention to any employee for injury compensable within the purview of this chapter and no employer shall permit or require any employee to contribute, directly or indirectly, to any fund for the payment of such medical, surgical, dental or hospital service within such hospital for the compensable injury. Any employer violating this subsection is liable in damages to the employer's employees as provided in section eight, article two of this chapter, and any employer or hospital or agent or employee thereof violating the provisions of this section is guilty of a misdemeanor and, upon conviction thereof, shall be punished by a fine not less than one hundred dollars nor more than one thousand dollars or by imprisonment not exceeding one year, or both.
(2) The provisions of this subsection shall not prohibit an employer, the successor to the commission, other private carrier or self-insured employer from participating in a managed health care plan, including, but not limited to, a preferred provider organization or program or a health maintenance organization or managed care organization or other medical cost containment relationship with the providers of medical, hospital or other health care. An employer, successor to the commission, other private carrier or self-insured employer that provides a managed health care plan approved by the commission or, upon termination of the commission, the Insurance Commissioner, for its employees or the employees of its insured may require an injured employee to use health care providers authorized by the managed health care plan for care and treatment of his or her compensable injuries. If the employer does not provide a managed health care plan or program, the claimant may select his or her initial health care provider for treatment of a compensable injury or disease, except as provided under subdivision (3) of this subsection. If a claimant wishes to change his or her health care provider and if his or her employer has established and maintains a managed health care plan, the claimant shall select a new health care provider through the managed health care plan. A claimant who has used the providers under the employer's managed health care plan may select a health care provider outside the employer's plan for treatment of the compensable injury or disease if the employee receives written approval from the commission to do so and the approval is given pursuant to criteria established by rule of the commission.
(3) If the commission enters into an agreement which has been approved by the board of managers with a managed health care plan, including, but not limited to, a preferred provider organization or program, a health maintenance organization or managed care organization or other health care delivery organization or organizations or other medical cost containment relationship with the providers of medical, hospital or other health care, then:
(A) If an injured employee's employer does not provide a managed health care plan approved by the commission for its employees as described in subdivision (2) of this subsection, the commission may require the employee to use health care providers authorized by the commission's managed health care plan for care and treatment of his or her compensable injuries; and
(B) If a claimant seeks to change his or her initial choice of health care provider where neither the employer nor the commission had an approved health care management plan at the time the initial choice was made, and if the claimant's employer does not provide access to such a plan as part of the employer's general health insurance benefit, then the claimant shall be provided with a new health care provider from the commission's managed health care plan available to him or her.
(c) When an injury has been reported to the commission by the employer without protest, the commission or self-insured employer may pay, within the maximum amount provided by schedule established under this section, bills for health care services without requiring the injured employee to file an application for benefits.
(d) The commission, successor to the commission, other private carrier or self-insured employer, whichever is applicable, shall provide for the replacement of artificial limbs, crutches, hearing aids, eyeglasses and all other mechanical appliances provided in accordance with this section which later wear out, or which later need to be refitted because of the progression of the injury which caused the devices to be originally furnished, or which are broken in the course of and as a result of the employee's employment. The commission, successor to the commission, other private carrier or self-insured employer shall pay for these devices, when needed, notwithstanding any time limits provided by law.
(e) No payment shall be made to a health care provider who is suspended or terminated under the terms of section three-c of this article except as provided in subsection (c) of said section.
(f) The commission, successor to the commission, other private carrier or self-insured employer, whichever is applicable, may engage in and contract for medical cost containment programs, pharmacy benefits management programs, medical case management programs and utilization review programs. Payments for these programs shall be made from the Workers' Compensation Fund or the funds of the successor to the commission, other private carrier, or self-insured employer. Any order issued pursuant to the program shall be interlocutory in nature until an objecting party has exhausted all review processes provided for by the commission, successor to the commission, other private carrier or self-insured employer, whichever is applicable.
(g) Notwithstanding the provisions of this section, the commission, successor to the commission, other private carrier or self-insured employer may establish fee schedules, make payments and take other actions required or allowed pursuant to article twenty-nine-d, chapter sixteen of this code.
