Note: Hospital separations were classified using ICD-10-AM. Grouping follows ICD-10 categories, so numbers for some categories may differ from results in other chapters. See ICD Codes for diseases and procedures for details. Numbers for 2004-05 include an estimate of the small number of interstate hospitalisations, data for which were unavailable at the time of production.
