CalOMS Treatment (CalOMS Tx) is California's data collection and reporting system for substance use disorder (SUD) treatment services.
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).

Master Provider File Database Management
The MPF Database is used to create identification records for providers who are either county- or state-contracted, and providers who obtain DMC certification. A 6-digit data reporting number (formerly known as “Provider ID Number”) is issued when a provider contracts with the state or county, or obtains DMC certification. For more information, please visit the Master Provider File webpage.
