This study highlights the diversity of diagnoses in Malaysian EDs and underscores the need for tailored DRGs to optimise healthcare resource allocation. The findings suggest that a principal diagnosis short list may support future efforts to improve classification consistency and inform resource planning, although its effect warrants empirical evaluation. Given the concentration of diagnoses within a limited number of ICD-10 codes, implementing DRGs in emergency care is both feasible and necessary. Future research should expand data collection to capture seasonal trends and refine the principal diagnosis list to further support DRG categorisation and ensure its applicability across varying healthcare demands.
