Basic Metadata
Note: There are no deaths listed for Opioid Related Disorders prior to 2016. Starting in 2018, we were able to collect ICD-10 Mortality multiple cause of death codes, which translates to the 2016 data year. Opioid deaths may appear to be low; this is because our underlying cause of death is actually for Mental and Behavioral Disorders due to Use of Opioids. For the actual burden of deaths due to the use of opioids, use the Any Mention files.
