Neither the employee nor the employer shall have any liability for medical treatment furnished without the authorization of the employer if the treatment is modified or denied by a utilization review decision, unless the utilization review decision is overturned by independent medical review in accordance with this section.
(f) As part of its notification to the employee regarding an initial utilization review decision based on medical necessity that denies or modifies a treatment recommendation, the employer shall provide the employee with a one-page form prescribed by the administrative director, and an addressed envelope, which the employee may return to the administrative director or the administrative director’s designee to initiate an independent medical review. The employee may also request independent medical review electronically under rules adopted by the administrative director. The employer shall include on the form any information required by the administrative director to facilitate the completion of the independent medical review. The form shall also include all of the following:
(1) Notice that the utilization review decision is final unless the employee requests independent medical review.
(2) A statement indicating the employee’s consent to obtain any necessary medical records from the employer or insurer and from any medical provider the employee may have consulted on the matter, to be signed by the employee.

(h) (1) The employee may submit a request for independent medical review to the division. The request may be made electronically under rules adopted by the administrative director. The request shall be made no later than as follows:
(A) For formulary disputes, 10 days after the service of the utilization review decision to the employee.
(B) For all other medical treatment disputes, 30 days after the service of the utilization review decision to the employee.
(2) If at the time of a utilization review decision the employer is also disputing liability for the treatment for any reason besides medical necessity, the time for the employee to submit a request for independent medical review to the administrative director or administrative director’s designee is extended to 30 days after service of a notice to the employee showing that the other dispute of liability has been resolved.
(3) If the employer fails to comply with subdivision (f) at the time of notification of its utilization review decision, the time limitations for the employee to submit a request for independent medical review shall not begin to run until the employer provides the required notice to the employee.
(4) A provider of emergency medical treatment when the employee faced an imminent and serious threat to his or her health, including, but not limited to, the potential loss of life, limb, or other major bodily function, may submit a request for independent medical review on its own behalf. A request submitted by a provider pursuant to this paragraph shall be submitted to the administrative director or administrative director’s designee within the time limitations applicable for an employee to submit a request for independent medical review.
(i) An employer shall not engage in any conduct that has the effect of delaying the independent review process. Engaging in that conduct or failure of the employer to promptly comply with this section is a violation of this section and, in addition to any other fines, penalties, and other remedies available to the administrative director, the employer shall be subject to an administrative penalty in an amount determined pursuant to regulations to be adopted by the administrative director, not to exceed five thousand dollars ($5,000) for each day that proper notification to the employee is delayed. The administrative penalties shall be paid to the Workers’ Compensation Administration Revolving Fund.
(j) For purposes of this section, an employee may designate a parent, guardian, conservator, relative, or other designee of the employee as an agent to act on his or her behalf. A designation of an agent executed prior to the utilization review decision shall not be valid. The requesting physician may join with or otherwise assist the employee in seeking an independent medical review, and may advocate on behalf of the employee.
(k) The administrative director or his or her designee shall expeditiously review requests and immediately notify the employee and the employer in writing as to whether the request for an independent medical review has been approved, in whole or in part, and, if not approved, the reasons therefor. If there appears to be any medical necessity issue, the dispute shall be resolved pursuant to an independent medical review, except that, unless the employer agrees that the case is eligible for independent medical review, a request for independent medical review shall be deferred if at the time of a utilization review decision the employer is also disputing liability for the treatment for any reason besides medical necessity.
(l) Upon notice from the administrative director that an independent review organization has been assigned, the employer shall electronically provide to the independent medical review organization under rules adopted by the administrative director a copy and list of all of the following documents within 10 days of notice of assignment:

(3) A copy of any materials the employee or the employee’s provider submitted to the employer in support of the employee’s request for the disputed treatment.
(4) A copy of any other relevant documents or information used by the employer or its utilization review organization in determining whether the disputed treatment should have been provided, and any statements by the employer or its utilization review organization explaining the reasons for the decision to deny or modify the recommended treatment on the basis of medical necessity. The employer shall concurrently provide a copy of the documents required by this paragraph to the employee and the requesting physician, except that documents previously provided to the employee or physician need not be provided again if a list of those documents is provided.
(m) Any newly developed or discovered relevant medical records in the possession of the employer after the initial documents are provided to the independent medical review organization shall be forwarded immediately to the independent medical review organization. The employer shall concurrently provide a copy of medical records required by this subdivision to the employee or the employee’s treating physician, unless the offer of medical records is declined or otherwise prohibited by law. The confidentiality of medical records shall be maintained pursuant to applicable state and federal laws.
(n) If there is an imminent and serious threat to the health of the employee, as specified in subdivision (c) of Section 1374.33 of the Health and Safety Code, all necessary information and documents required by subdivision (l) shall be delivered to the independent medical review organization within 24 hours of approval of the request for review.

Notice shall be given to the independent medical review organization within five working days of the change in administrator taking effect.
