(1) Programs administered by any Indian tribe or tribal organization under the authority of the Indian Self-Determination Act [25 U.S.C. 450f et seq.] shall be eligible for funds appropriated under the authority of this section on an equal basis with programs that are administered directly by the Service.
(2) If any funds allocated to a tribe or service unit under the authority of this section are used for a contract entered into under the Indian Self-Determination Act, a reasonable portion of such funds may be used for health planning, training, technical assistance, and other administrative support functions.

Any funds appropriated under the authority of this section shall be designated as the Indian Health Care Improvement Fund.
