[part 1.7. Health Facilities Disclosure Act] of California Health And Safety Code >> Division 1. >> Part 1.7.

"Health facility," as used in this chapter, means any general acute care hospital required to be licensed pursuant to Chapter 2 (commencing with Section 1250) of Division 2.
Within seven days after completion of the patient's itemized bill, every health facility shall provide to the primary attending health care practitioner a copy, upon written request specifying the individual patient, of the complete itemized charges for services rendered by the health facility to the health care practitioner's patient when the primary attending health care practitioner is not employed by the health facility nor is a member of an integrated group practice that provided the health facility services.
The primary attending health care practitioner's written request to the health facility shall specify the records to be copied pursuant to Section 440.20 and shall include a fee to defray the cost of copying, not to exceed twenty-five cents ($0.25) per page, plus any reasonable costs of clerical services incurred in locating and making the records available.
The primary attending health care practitioner shall obtain prior written consent from each patient for whom a billing is requested, authorizing the release of the patient's billing. A copy of this signed patient consent form shall be forwarded to the health care facility as part of the written request for itemized billings.
No information, other than the itemized billing set forth in Section 440.20, that is prohibited from being released by any other provision of law shall be made available pursuant to Section 440.20.
