National Health Service Corps Improvements Act of 1989

National Health Service Corps Improvements Act of 1989 - Amends the Public Health Service Act to create a third level of priorities, with regard to approving applications and accepting contracts under the National Health Service Corps Scholarship Program (Scholarship Program), favoring individuals who are residents of health manpower shortage areas, who are disadvantaged or minority students, or who are attending (or planning to attend) an institution that provides rural training opportunities. Adds the same priorities (but without reference to levels of priorities) to provisions relating to application approval and contract acceptance under the National Health Service Corps Loan Repayment Program (Loan Program).

Adds a requirement that a Scholarship Program recipient agree to participate in an annual interview with an official of the institution regarding progress and development of the individual within the course of study.

Adds a requirement that the Secretary of Health and Human Services include, in an existing annual report to the Congress on the Scholarship Program, the top half of U.S. medical schools that place a greater percentage of their graduates in underserved areas than the national average of such placement.

Directs the Secretary to: (1) ensure that educational institutions that offer degrees of interest to the Scholarship Program provide applicants for admission information on that Program; (2) provide all Scholarship Program participants with the quarterly publication of the National Health Service Corps; and (3) award, to the extent practicable, 450 scholarships for each school year.

Authorizes the Secretary, subject to exception, to pay, under the Loan Program, not less than a specified amount (currently, up to the same amount) for each year of obligated service.

Directs the Secretary to promulgate regulations regarding the period of obligated service, including regulations relating to rotating Scholarship Program Corps physicians among separate facilities, extending the required service time to compensate for periods when such physicians were absent from their primary site, and permitting other Corps physicians to be temporarily reassigned to other facilities to ensure physician continuity.
