Rural Healthcare Improvement Act of 2003

Rural Healthcare Improvement Act of 2003 - Amends title XVIII (Medicare) the Social Security Act (SSA) with respect to services in rural areas, inpatient hospital services, physician services, physician updates, home health services, and the Office of Rural Health Policy.

Amends SSA title XIX (Medicaid) to provide for a special, temporary increase in disproportionate share hospital (DSH) allotments on a one-time, non-cumulative basis, and an increase in the floor for treatment as a low DSH State. Provides for allotment adjustments for FY 2004 and 2005 for States without a DSH allotment owing to revocation or termination of a certain waiver.

(The Medicare provisions of H.R. 3549 are identical to title I of S. 1926, the Support Our Health Care Providers Act of 2003, which in turn is identical, except with respect to any provider cuts or premium increases, to title IV of the conference report of H.R. 1, the Medicare Prescription Drug and Modernization Act of 2003, which became Public Law 108-173 on December 8, 2003. The Medicaid provision is very similar to one in title VI, subtitle A of H.R. 3549.)
