These datasets are part of the California Health and Human Services Agency (CalHHS) Data De-Identification Guidelines (DDG) in the "State and County Population Projections" Appendix. The DDG assists CalHHS departments in evaluating data for public release while ensuring the privacy of individuals represented in the data. California population estimates serve as a foundation for the population-based scoring assessments outlined in the DDG.

This dataset is a catalog of all the datasets available on the CalHHS Open Data Portal. Each item in the catalog represents a dataset and includes the associated metadata and additional information.

This dataset identifies California’s eligibility groups by aid code. California uses aid codes to account for eligibility group populations and the eligibility requirements, scope of benefits, services, costs, claims, encounter data, and managed care arrangements related to those populations. Aid codes in this dataset are mapped to the Transformed Medicaid Statistical Information System (T-MSIS) eligibility group descriptions and codes. California uses this mapping to submit claims data, enrollee encounter data, and supporting information to the Centers for Medicare & Medicaid Services (CMS), as required by Section 4735 of the Balanced Budget Act of 1997 and Section 6504 of the Affordable Care Act for the purpose of program integrity, program oversight, and administration. This dataset includes aid codes that do not have Medi-Cal benefits or have benefits and are not federal programs. Some aid codes may appear to be identical but possess distinct benefits or grouping factors. An aid code may appear more than once if multiple populations are represented in one aid code and can be identified and mapped to distinct T-MSIS groups.

This dataset includes information regarding annual Medi-Cal eligibility renewals conducted for beneficiaries by counties each month. The data is from the Statewide Automated Welfare System (SAWS), which determines Medi-Cal eligibility and conducts ongoing case management. The SAWS reports the number of renewals due and the renewals completed by the due date and within the renewals processing timeframe. This dataset is part of the public reporting requirements set forth in California Welfare and Institutions Code 14102.5(3) et seq.
