  • a For each opioid prescription filled, we used the AHRQ Multi-level CCS to comprehensively assess all health problems (eg, diagnoses) that were filed during health care encounters across the care continuum (eg, inpatient or outpatient) during the 7 d preceding OE. The AHRQ CCS system groups related International Classification of Diseases, Ninth Revision, Clinical Modification codes into mutually exclusive categories. We determined frequencies of all CCS level 2 diagnoses to determine the most prevalent health problems in the 7 d preceding OE. Of these, we associated OE first to diagnoses with clinical indications for OE (eg, traumatic injury, malignancy). If there was not a forthcoming clinical indication for OE, we then considered other related diagnoses (eg, infection, nontraumatic musculoskeletal condition), and lastly the categories of symptoms or descriptions of the health care encounter itself (eg, ill-defined symptoms, signs, and conditions).
