in effect(a)
For services rendered on or after January 1, 2001, a health care service plan or managed care entity, as described in subdivision (f) of Section 1345 of the Health and Safety Code, shall have a duty of ordinary care to arrange for the provision of medically necessary health care service to its subscribers and enrollees, where the health care service is a benefit provided under the plan, and shall be liable for any and all harm legally caused by its failure to exercise that ordinary care when both of the following apply:
(1)
The failure to exercise ordinary care resulted in the denial, delay, or modification of the health care service recommended for, or furnished to, a subscriber or enrollee.
(2)
The subscriber or enrollee suffered substantial harm.
(b)
For purposes of this section: (1) substantial harm means loss of life, loss or significant impairment of limb or bodily function, significant disfigurement, severe and chronic physical pain, or significant financial loss; (2) health care services need not be recommended or furnished by an in-plan provider, but may be recommended or furnished by any health care provider practicing within the scope of his or her practice; and (3) health care services shall be recommended or furnished at any time prior to the inception of the action, and the recommendation need not be made prior to the
occurrence of substantial harm.

(h)
This section does not abrogate or limit any other theory of liability otherwise available at law.

(k)
(1)
A person may not maintain a cause of action pursuant to this section against any entity required to comply with any independent medical review system or independent review system required by law unless the person or his or her representative has exhausted the procedures provided by the applicable independent review system.
(2)
Compliance with paragraph (1) is not required in a case where either of the following applies:
(A)
Substantial harm, as defined in subdivision (b), has occurred prior to the completion of the applicable review.
(B)
Substantial harm, as defined, in subdivision (b), will imminently occur prior to the completion of the applicable review.

If any provision of this section or the application thereof to any person or circumstance is held to be unconstitutional or otherwise invalid or unenforceable, the remainder of the section and the application of those provisions to other persons or circumstances shall not be affected thereby.
