N.C. Gen. Stat. § 58-52-5
Notwithstanding any other provisions of Articles 1 through 64 of this Chapter or any other law which may be inconsistent herewith, any insurer may join with one or more other insurers to plan, develop, underwrite, offer, sell and provide to or for any resident person of this State, or of another state if permitted by the laws of such other state, who is 65 years of age or over and to the spouse of such person, insurance against financial loss from accident or sickness, or both. Such insurance may also cover an employer's nonresident employees and nonresident retired employees 65 years of age or older and their spouses, provided such employees are regularly employed within this State or were so employed at the time of their retirement. Such insurance may be offered, issued and administered through an association of two or more insurers which association is formed for the purpose of offering, selling, issuing and administering such insurance, and may be in the form of a policy insuring a resident who is 65 years of age or older, and the spouse of such resident, if any, or in the form of a group policy insuring residents 65 years of age or older and the spouses of such residents, or in both forms. On such insurance each insurer shall be severally liable for a percentage of the risks determined under the articles of association of the association. The insurer members of such association may agree with respect to premium rates, policy provisions, commission rates and other matters within the scope of this Article.
