Diagnostic codes located in the International Classification of Diseases (ICD) are used to justify treatment and reimbursement for medical costs and provide statistical data on the prevalence and incidence of diseases and/or health problems. Since 1979, diagnostic codes for child and adult maltreatment syndrome have been available. The purpose of this study was to better understand the reasons for the lack of use of these diagnostic codes for child and adult abuse. This was a qualitative study using focus groups of “experts” with experience in caring and advocating for victims of abuse and/or issues related to coding abuse. Three separate groups of experts were convened and included: one each for child, adult (primarily woman), and elder abuse. For child and elder abuse the key experts were nationally recognized physicians and for adult abuse the experts were the State coalition for battered women. Data consisted of the text from the transcriptions of the three focus groups. Overall, the discussions on the use of diagnostic codes for abuse suggest that the negative implications of coding outweigh the benefits. The discussions showed that the diagnostic coding of child abuse compared with adult abuse may have more merit, primarily because the abuse must be reported anyway. Potential limitations were suggested in the findings because only three focused discussions were conducted in one State. The study opens up a dialogue on the controversial use of diagnostic codes for child and adult abuse in particular. Appendix and references
