Health & Safety Code §1371.4(d)

If there is a disagreement between the health care service plan and the provider regarding the need for necessary medical care, following stabilization of the enrollee, the plan shall assume responsibility for the care of the patient either by having medical personnel contracting with the plan personally take over the care of the patient within a reasonable amount of time after the disagreement, or by having another general acute care hospital under contract with the plan agree to accept the transfer of the patient as provided in Section 1317.2, Section 1317.2a, or other pertinent statute. However, this requirement shall not apply to necessary medical care provided in hospitals outside the service area of the health care service plan. If the health care service plan fails to satisfy the requirements of this subdivision, further necessary care shall be deemed to have been authorized by the plan. Payment for this care may not be denied.
