To the Editor: In the report on opioid overdose-related deaths, Dr Bohnert and colleagues1 stated in the methods that “The opioid analgesic medications dispensed by VHA pharmacies during FY2004 through FY2008 were codeine, morphine, oxycodone, hydrocodone, oxymorphone, and hydromorphone,” suggesting that all these opioids were studied. However, the authors also stated that “Semisynthetic opioids were not included because they correspond with ICD-10 T-code 40.4.” Data in tables were expressed in morphine equivalencies only. Oxycodone, hydrocodone, oxymorphone, and hydromorphone are semisynthetic opioids.2 Were these semisynthetic opioids included or excluded from the study?
