As @Maria points out, a code of ethics would be formed from the governing regulatory bodies surrounding the profession within the country concerned. For example:
All APA members are bound by the ethical code of the medical profession, specifically defined in the American Psychiatric Association’s Principles of Medical Ethics With Annotations Especially Applicable to Psychiatry (“Principles”) (American Psychiatric Association, n.d.).
A copy of the APA code of ethics is available on the website page linked.
The governing regulatory body the practitioner is licensed through will handle any ethical concerns surrounding a registered practitioner and if they consider that they have acted unethically, the regulatory body can take relevant actions including removing their license to practice.
To view the current code of ethics you need to go to the relevant regulatory body, for which you would need to know who the practitioner is registered with.
