California Outcomes Measurement System Treatment
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.
CalOMS Tx data is due to DHCS by the 15th of each month, or approximately within 45 days of the report month.
Counties and direct providers 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).
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 SUD treatment providers that receive state or federal funding through the state or the county and certified Drug Medi-Cal providers and Narcotic Treatment Programs must report whether or not they receive public funding.
- DATAR reports are due each month by the 10th of the following month.
