The California Outcomes Measurement System Treatment (CalOMS Tx) is California’s data collection and reporting system for substance use disorder (SUD) treatment services. Data collected facilitates improvements in treatment services delivered to those in need. This data collection is key to ensuring quality improvements that positively affect the lives of SUD service recipients, their families, communities, and public health and social systems.

• Participating treatment providers that receive SUD treatment funding from DHCS are required to report treatment outcomes data.
• CalOMS Tx data is due to DHCS by the 15th of each month, or approximately within 45 days of the report month.
• Counties may submit their monthly CalOMS Tx data as soon as it is available, or at any time during the report month (the calendar month in which the admissions, discharges, or annual updates occur). 

The CalOMS Tx resource materials can be accessed by authorized CalOMS users at: Behavioral Health Information Systems

For guidance on submitting complete and accurate CalOMS Tx data, please refer to the CalOMS Tx Data Compliance Standards V.3.

Drug and Alcohol Treatment Access Report

The Drug and Alcohol Treatment Access Report (DATAR) is a DHCS system to collect data on SUD treatment capacity and waiting lists and is considered a supplement to CalOMS Tx.   

All county contracted SUD treatment providers that receive any SUD treatment funding from DHCS are required to submit the one-page DATAR form to DHCS each month. In addition, certified and county contracted Drug Medi-Cal providers and Licensed Narcotic Treatment Programs (NTP) must report whether or not they receive public funding.

• DATAR reports are due each month by the 10th of the following month. 

Authorized DATAR users may access the Behavioral Health Information System Portal here: DATAR-WEB REPORTING SYSTEM (AUTHORIZED USERS ONLY)
