N.J. Stat. § 17:48A-3
The Commissioner of Banking and Insurance shall issue such certificate of authority to any such medical service corporation of this State when it shall have filed in the Department of Banking and Insurance a certified copy of its charter or certificate of incorporation, a copy of its by-laws certified by the lawful custodian of the original, a statement of its financial condition in such form and detail and containing such matters as the Commissioner of Banking and Insurance shall require, signed and sworn to by its president and secretary or other proper officers, and when the Commissioner of Banking and Insurance is satisfied, on the basis of examination or otherwise, that the corporation is organized without capital stock and not for pecuniary profit and has complied with the requirements of this chapter and that its condition or methods of operation are not such as would render its operations hazardous to the public or its subscribers. No change in, or amendment to, or alteration in, addition to, or substitution of any document, instrument or other papers so filed shall become operative or effective until the same shall also have been filed in a similar manner. The certificate of authority issued by the commissioner shall specify the county or counties in which the corporation may conduct its business. Such certificate may be amended from time to time to include additional counties on the basis of qualification pursuant to the provisions of this act. No such certificate shall be issued to authorize a corporation to transact business in any county, or if issued, the authority with respect to such county shall be canceled by the commissioner, if he shall find that less than fifty-one per centum (51%) of the eligible physicians in any county are participating physicians. No certificate of authority shall be issued to any medical service corporation not incorporated as a corporation without capital stock not for pecuniary profit under the laws of this State.
