Does physician privilege apply to the disclosure of confidential information?

Real parties in interest interpret the physician-patient privilege as excluding physician orders. This narrow interpretation is contrary to the plain language of Evidence Code section 992, which defines "confidential communication" to include not only information disclosed by the patient but also "a diagnosis made and the advice given by the physician." (See Carlton v. Superior Court (1968) 261 Cal.App.2d 282, 288289, 67 Cal.Rptr. 568 [physician orders within scope of privilege].)⁵
