Main points• ICD-10 results in 3% increase in overall case counts
+515, - 119; net = 369
• Falls (ICD-9 E880-E888) - particular problems No equivalent to E887 - often used for persons aged 65+ yrs Most E887 shift to X59 Proposed solution - X59 + ‘Fractures’
• Injury matrix 10 of 17 Unintentional categories - some problems Less problems for suicide (and homicide) Undetermined - some problems but small numbers
