Common terms and definitions from the Indiana Rules for Prescribing Controlled Opioid Substances
The Indiana Final Rule provides specific definitions for some common health care terms related to chronic pain patients.
Knowing how these opioid related terms are defined in the final rule allows us all to be on the same page. And being on the same page when managing our chronic pain patients is key to not only following the rules and regulations but also in providing patients the best care we possible can.
