All general acute care hospitals except for children's hospitals will be reimbursed for NBHS services according to the Texas Medicaid prospective payment methodology based on the Diagnosis Related Group (DRG). The cost of providing this service is factored into the calculation of the DRG relative weights. The Texas Department of State Health Services recognizes that it is necessary to recalculate the DRG relative weights periodically to account for changes in resource consumption. Accordingly, the Department of State Health Services makes adjustments to the DRG classifications and relative weights at least every three years. These adjustments are made to reflect changes in treatment patterns, technology, and any other factors that may change the relative use of hospital resources.
