4600.3. (a) (1) Notwithstanding Section 4600, when a self-insured employer, group of self-insured employers, or the insurer of an employer contracts with a health care organization certified pursuant to Section 4600.5 for health care services required by this article to be provided to injured employees, those employees who are subject to the contract shall receive medical services in the manner prescribed in the contract, providing that the employee may choose to be treated by a personal physician, personal chiropractor, or personal acupuncturist that they have designated prior to the injury, in which case the employee shall not be treated by the health care organization. Every employee shall be given an affirmative choice at the time of employment and at least annually thereafter to designate or change the designation of a health care organization or a personal physician, personal chiropractor, or personal acupuncturist. The choice shall be memorialized in writing and maintained in the employee’s personnel records. The employee who has designated a personal physician, personal chiropractor, or personal acupuncturist may change their designated caregiver at any time prior to the injury. Any employee who fails to designate a personal physician, personal chiropractor, or personal acupuncturist shall be treated by the health care organization selected by the employer. If the health care organization offered by the employer is the workers’ compensation insurer that covers the employee or is an entity that controls or is controlled by that insurer, as defined by Section 1215 of the Insurance Code, this information shall be included in the notice of contract with a health care organization.
(2) Each contract described in paragraph (1) shall comply with the certification standards provided in Section 4600.5, and shall provide all medical, surgical, chiropractic, acupuncture, licensed clinical social worker, and hospital treatment, including nursing, medicines, medical and surgical supplies, crutches, and apparatus, including artificial members, that is reasonably required to cure or relieve the effects of the injury, as required by this division, without any payment by the employee of deductibles, copayments, or any share of the premium. However, an employee may receive immediate emergency medical treatment that is compensable from a medical service or health care provider who is not a member of the health care organization.
(3) Insured employers, a group of self-insured employers, or self-insured employers who contract with a health care organization for medical services shall give notice to employees of eligible medical service providers and any other information regarding the contract and manner of receiving medical services as the administrative director may prescribe. Employees shall be duly notified that if they choose to receive care from the health care organization they must receive treatment for all occupational injuries and illnesses as prescribed by this section.
(b) Notwithstanding subdivision (a), no employer which is required to bargain with an exclusive or certified bargaining agent which represents employees of the employer in accordance with state or federal employer-employee relations law shall contract with a health care organization for purposes of Section 4600.5 with regard to employees whom the bargaining agent is recognized or certified to represent for collective bargaining purposes pursuant to state or federal employer-employee relations law unless authorized to do so by mutual agreement between the bargaining agent and the employer. If the collective bargaining agreement is subject to the National Labor Relations Act, the employer may contract with a health care organization for purposes of Section 4600.5 at any time when the employer and bargaining agent have bargained to impasse to the extent required by federal law.
(c) (1) When an employee is not receiving or is not eligible to receive health care coverage for nonoccupational injuries or illnesses provided by the employer, if 90 days from the date the injury is reported the employee who has been receiving treatment from a health care organization or their physician, chiropractor, acupuncturist, or other agent notifies their employer in writing that the employee desires to stop treatment by the health care organization, they shall have the right to be treated by a physician, chiropractor, or acupuncturist or at a facility of their own choosing within a reasonable geographic area.
(2) When an employee is receiving or is eligible to receive health care coverage for nonoccupational injuries or illnesses provided by the employer, and has agreed to receive care for occupational injuries and illnesses from a health care organization provided by the employer, the employee may be treated for occupational injuries and diseases by a physician, chiropractor, or acupuncturist of their own choice or at a facility of their own choice within a reasonable geographic area if the employee or their physician, chiropractor, acupuncturist, or other agent notifies their employer in writing only after 180 days from the date the injury was reported, or upon the date of contract renewal or open enrollment of the health care organization, whichever occurs first, but in no case until 90 days from the date the injury was reported.
(3) For purposes of this subdivision, an employer shall be deemed to provide health care coverage for nonoccupational injuries and illnesses if the employer pays more than one-half the costs of the coverage, or if the plan is established pursuant to collective bargaining.
(d) An employee and employer may agree to other forms of therapy pursuant to Section 3209.7.
(e) An employee enrolled in a health care organization shall have the right to no less than one change of physician on request, and shall be given a choice of physicians affiliated with the health care organization. The health care organization shall provide the employee a choice of participating physicians within five days of receiving a request. In addition, the employee shall have the right to a second opinion from a participating physician on a matter pertaining to diagnosis or treatment from a participating physician.
(f) Nothing in this section or Section 4600.5 shall be construed to prohibit a self-insured employer, a group of self-insured employers, or insurer from engaging in any activities permitted by Section 4600.
(g) Notwithstanding subdivision (c), in the event that the employer, group of employers, or the employer’s workers’ compensation insurer no longer contracts with the health care organization that has been treating an injured employee, the employee may continue treatment provided or arranged by the health care organization. If the employee does not choose to continue treatment by the health care organization, the employer may control the employee’s treatment for 30 days from the date the injury was reported. After that period, the employee may be treated by a physician of their own choice or at a facility of their own choice within a reasonable geographic area.
