DRG Estimator

Estimate AR-DRG candidate groupings from MBS item numbers and optional clinical context.

For Forecasting Only — Not for Clinical or Billing Use

Results are indicative estimates only. They must not be used for official DRG grouping, clinical decision-making, or billing purposes. Official grouping requires coded episode data and a licensed grouper.
