This list replaces and supplements the FR notice dated January 10, 1984 (49 FR 1291) establishing CHSDAs and FR notice dated August 25, 1988 (53 FR 32460) establishing Health Service Delivery Areas (HSDAs).

**SUPPLEMENTARY INFORMATION:**
On September 16, 1987, the Department of Health and Human Services (HHS) published new final regulations governing eligibility for the Indian Health Service (IHS) services at 52 FR 35044. In the Fiscal Year 1988 Appropriations Act, Section 315, Public Law 100-202, Congress delayed implementation of the new regulations for one year and imposed a moratorium on the use of appropriated funds for implementation of the new regulations in subsequent fiscal years. In Section 719(a) ofthe Indian Health Care Amendments of 1988, Public Law 100-713, Congress directed that during the moratorium that IHS should provide services pursuant to the criteria for eligibility for such services that were in effect on September 15, 1987. Because the moratorium continues in effect, for the convenience of the public, the HHS republished the eligibility regulations in effect on September 15, 1987. These regulations appear re-designated in the Code of Federal Regulations at Title 42, Part 136, Subparts A-C.
The regulations of September 16, 1987, that are under moratorium, provided that the IHS would designate and publish as a notice in the *Federal Register* specific geographic areas within the United States including Indian reservations and areas surrounding those reservations as Health Service Delivery Areas (HSDAs). The HSDAs are the geographic areas within which *direct* and *contract health services* may be made available by the IHS to eligible individuals who reside within the areas. In anticipation of the Congressional moratorium being lifted, the IHS on August 25, 1988 published at 53 FR 32460 a list of HSDAs. If the Congressional moratorium were lifted, the list was to be effective September 16, 1988 or such later date as may be estblished by Congress. Because the Congressional moratorium continues in effect, the HSDA list never became effective.
As noted above, the IHS currently provides services under regulations in effect on September 15, 1987 and republished at 42 CFR Part 136, Subparts A-C. Subpart C defines a Contract Health Service Delivery Area (CHSDA) as the geographic area within which contract health services will be made available by the IHS to members of an identified Indian community who reside in the area. It should be clearly understood that residence within a CHSDA or Service Delivery Area (SDA) by a person who is within the scope of the Indian health program, as set forth in 42 CFR 136.12, creates no legal entitlement to contract health services but only potential eligibility for services. Services needed but not available at an IHS/tribal facility are provided under the Contract Health Services (CHS) program depending on the availability of funds, the person's relative medical priority, and the actual availability and accessibility of alternate resources in accordance with the regulations.
The purpose of this FR notice is to revise and update the list of CHSDAs and SDAs as last published in 1984. The current eligibility regulations at 42 CFR 136.22(a)(1)-(5) defines certain CHSDAs by designating some States as CHSDAs and certain counties within a state as a CHSDA. In addition, Section 136.22(a)(6) provides that:
With respect to all other reservations ( *i.e.* , other than those not specifically listed in 42 CFR 136.22(a)(1)-(5)) within the scope of the Indian health program, the CHSDA shall consist of a county which includes all or part of a reservation, and any county or counties which have a common boundary with the reservation.
The counties included or excluded from the following list of CHSDAs were determined by applying the regulations at 42 CFR 136.22 except where otherwise provided for by regulations, public laws, or congressional action in the appropriations process.
The list includes those CHSDAs as defined in the regulations at 42 CFR 136.22, including those CHSDAs designated as exceptions within the funded scope and exceptions provided by legislation. In addition, many of the newly recognized tribes do not have reservations and either Congress has legislatively designated counties to serve as SDAs or the Director, IHS exercised reasonable administrative discretion to designate SDAs to effectuate the intent of Congress for these tribes. The SDAs function as CHSDAs for the purposes of operating a CHS program pursuant to the ISDEAA, Pub. L. 93-638. Thus, the CHSDA list incorporates the SDAs that operate as CHSDAs for newly recognized tribes recognized as of the date of publication of this Notice.
The CHSDA and SDA list has been modified and updated to include the name of the tribe, with the respective reservation in parenthesis underneath the name of the tribe, and/or the counties comprising the CHSDA or SDA. Any mistakes in the list of CHSDAs and SDAs should be brought to the attention of Hankie Ortiz, Director, Division of Regulatory Affairs, 801 Thompson Avenue, Rockville, Maryland 20852, telephone: (301) 443-1116. Any corrections of mistaken inclusions or exclusions of a county or counties in a CHSDA or SDA may be made administratively and included in a later FR notice. Redesignation of areas included or excluded from a CHSDA for reasons other than a mistake is governed by 42 CFR 136.22(b) and may be made by the Director, IHS.
