Identification of Alcohol and Other Drug Services (IAD)

This measure summarizes the number and percentage of members who had a service for alcohol and other drug (AOD) abuse or dependence (i.e., a claim with both a diagnosis of AOD abuse or dependence and a specific AOD-related service) during the measurement year. The measure is reported using the following service categories:

  • Inpatient.
  • Intensive outpatient or partial hospitalization.
  • Outpatient or an ambulatory medication-assisted treatment (MAT) dispensing events.
  • Emergency department (ED).
  • Telehealth.
  • Any service

In each category, the organization reports by age and sex the number of members with an AOD diagnosis who received the service and the percentage of members who received the service out of all members with a chemical dependency benefit.

Why It Matters

In 2015, 20.8 million people (7.8% of the U.S. population) 12 years of age and older were classified as having a substance use disorder (SUD) within the past year (SAMHSA, 2016). An SUD is recurrent use of alcohol and/or drugs that causes significant impairment, both clinically and functionally (SAMHSA, 2015). Commonly abused substances include alcohol, illicit drugs, marijuana, prescription pain relievers, cocaine, methamphetamine, heroin and stimulants (SAMHSA 2016).

Of the nearly 21 million Americans with an SUD in 2015, only 3.5 million adults received any substance use treatment; 2.3 million received treatment in a specialty substance use disorder program (HHS, 2016; SAMHSA, 2016).
