(a) In this subpart—

Billing unit is a subdivision of the tribal employer's workforce that aligns tribal employees for purposes of administering FEHB enrollment and collection of payment. A billing unit may be either governmental or commercial or a combination of both. So long as a tribal employer purchases FEHB for at least one billing unit that is carrying out at least one program under ISDEAA or IHCIA, the tribal employer may purchase FEHB for other billing units without regard to its programs.

Pay period is the interval of time for which a paycheck is issued by the tribal employer for work performed by the tribal employee.

Paymaster is the entity designated by OPM as responsible for receiving FEHB premiums from the tribal employer, forwarding premiums to the Employees Health Benefits Fund, and maintaining enrollment records for all participating tribal employers.

Payment is the sum of the tribal employer's share of premium plus the tribal employees' share of premium plus any administrative fees or costs required under this subpart, due for the enrollment, in the aggregate, of the tribal employer's tribal employees.

Tribal employee is a full-time or part-time common law employee of a tribal employer. An individual is a common law employee if, based on all the facts and circumstances, the tribal employer has the right to control and direct the individual who performs the services, not only as to the result to be accomplished by the work but also as to the details and means by which that result is accomplished. This determination is based on all facts and circumstances and shall be guided by the factors described by the Internal Revenue Service in Rev. Rul. 87-41, 1987-1 C.B. 296 and referenced in Joint Committee on Taxation report JCX-26-07 Present Law and Background Relating to Worker Classification for Federal Tax Purposes, dated May 7, 2007, and the determination shall be consistent with the tribal employer's determination of common law employee status for Federal employment tax purposes, if any. For purposes of this subpart, tribal employees do not include retirees or annuitants of a tribal employer, volunteers of a tribal employer, or others who are not common law employees of a tribal employer. Categories of excluded tribal employees are described at §890.1405(b). FEHB benefits available to tribal employees are set forth in this subpart and to the extent there exists any ambiguity or inconsistency between this subpart and other subparts of part 890, the terms of this subpart will govern FEHB benefits available to tribal employees.

Tribal employer is an Indian tribe or tribal organization (as those terms are defined in 25 U.S.C. Chapter 18, “Indian Health Care”) carrying out at least one program under the Indian Self-Determination and Education Assistance Act or an urban Indian organization (as that term is defined in 25 U.S.C. Chapter 18, “Indian Health Care”) carrying out at least one program under the title V of the Indian Health Care Improvement Act, provided that the tribe, tribal organization, or urban Indian organization certifies entitlement to purchase FEHB according to the process described in Subpart N. FEHB benefits that tribal employers are entitled to purchase for their tribal employees are set forth in this subpart and to the extent there exists any ambiguity or inconsistency between this subpart and other subparts of part 890, the terms of this subpart will govern FEHB benefits available for purchase by tribal employers.
