(a) Any physician and surgeon or any doctor of podiatric medicine, as the case may be, who as a sole proprietor, or in a partnership, group, or professional corporation, desires to practice under any name that would otherwise be a violation of Section 2285 may practice under that name if the proprietor, partnership, group, or corporation obtains and maintains in current status a fictitious-name permit issued by the Division of Licensing, or, in the case of doctors of podiatric medicine, the California Board of Podiatric Medicine, under the provisions of this section.
(b) The division or the board shall issue a fictitious-name permit authorizing the holder thereof to use the name specified in the permit in connection with his, her, or its practice if the division or the board finds to its satisfaction that:
