AB 403 adds Section 14132.37 to the Welfare and Institutions Code, directing the Department of Health Care Services (DHCS) to perform and publish an annual analysis of the Medi‑Cal community health worker (CHW) services benefit established under Section 14132.36. The analysis must assess CHW capacity and beneficiary needs, examine utilization and outreach efforts by Medi‑Cal managed care plans, disaggregate findings by region and demographic factors, and report reimbursement totals paid for CHW services.
The bill matters because it creates a recurring, legislatively mandated data stream about a nascent Medi‑Cal benefit that many counties, community‑based organizations, and plans are still operationalizing. The required disaggregation, utilization metrics, and reimbursement reporting are designed to inform workforce planning, contracting, and equity monitoring — but the statute leaves several practical and technical questions about data collection, statistical thresholds, and funding for implementation unresolved.
At a Glance
What It Does
The bill requires DHCS to annually analyze the CHW Medi‑Cal benefit (Section 14132.36), review managed‑care outreach and education, and publish the analysis and submit it to the Legislature; the first report is due July 1, 2027. The statute lists specific data elements the analysis must contain: capacity and needs assessments, utilization patterns, provider referrals, employer types, demographic disaggregation, and total reimbursement dollars.
Who It Affects
DHCS must compile and publish the report; Medi‑Cal managed care plans must supply outreach assessments and utilization data; providers and community‑based organizations that contract CHWs will be sources of staffing and reimbursement figures; and Medi‑Cal beneficiaries — particularly populations defined by race, language, region, and age — are the subject of the disaggregated analysis.
Why It Matters
The requirement creates a regular evidentiary basis for decisions on CHW workforce development, plan oversight, and potential payment or contracting changes. For compliance officers and program managers, the law creates new reporting expectations and a potential lever for funding or policy change based on published metrics and identified gaps.

What This Bill Actually Does
AB 403 directs DHCS to take a deliberately empirical approach to the CHW Medi‑Cal benefit by producing an annual analysis that goes well beyond a headline usage metric. The department must assess both supply (how many CHWs are contracted and where they work) and demand (how many beneficiaries are eligible and served), and then break those findings down across geography, race, ethnicity, language, age, and by managed care plan where applicable.
DHCS must also evaluate the outreach and education activities that managed care plans conduct under Section 14132.36.
The statute enumerates concrete data points DHCS must gather: the types of CHW services delivered, referral sources, counts of contracted CHWs by employer type (CBOs, clinics, hospitals, licensed providers), the diversity of the CHW workforce, beneficiaries served by demographic groups, and an estimate of how many CHW entities or workers are needed to meet projected demand. It also mandates reporting the total dollar amounts reimbursed to both providers and 'supervising entities' for CHW services, which creates a direct line of sight into Medi‑Cal expenditures tied to this benefit.Two technical rules will shape implementation.
First, DHCS must limit published demographic breakdowns to categories that reach statistical significance, which is intended to avoid misleading small‑cell inferences but will require a documented threshold and methodology. Second, all data collection and publication must exclude personally identifiable information to protect beneficiary privacy.
DHCS must submit the full analysis to the Legislature under Government Code Section 9795 and post it online; the first report must be completed, submitted, and published by July 1, 2027.Operationally, the law implies multiple upstream reporting relationships: managed care plans and fee‑for‑service billing systems will be primary data sources for utilization and reimbursement figures; employers (CBOs, clinics, hospitals) will need to provide counts and demographic profiles of their CHWs; and DHCS will be responsible for aggregating, validating, and applying statistical tests before publication. Because the statute both quantifies reimbursement flows and asks DHCS to estimate unmet need — including the number of additional contracted CHW entities required — the report is likely to be used by policymakers and budget analysts to consider future rate adjustments, workforce investments, or targeted outreach strategies.
The Five Things You Need to Know
DHCS must produce an annual analysis of the Medi‑Cal CHW benefit, submit it to the Legislature under Gov. Code §9795, and publish it online; the first report is due July 1, 2027.
The required analysis must assess CHW capacity and beneficiary needs and provide disaggregations by geographic region, race, ethnicity, language, age, and, where applicable, by Medi‑Cal managed care plan.
DHCS must evaluate outreach and education activities conducted by each Medi‑Cal managed care plan under Section 14132.36 as part of the annual review.
The report must include utilization and operational metrics — service types and their relative frequency, referral sources by provider type, counts of CHWs by employer type, and an estimate of additional CHWs or contracting entities needed.
DHCS must report total Medi‑Cal reimbursement dollars for CHW services paid to providers and supervising entities while excluding any personally identifiable information and publishing only statistically significant demographic data.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Definition: Community Health Worker (CHW)
The section incorporates the CHW definition from Welfare & Institutions Code §18998(b), explicitly including promotores and community health representatives. Practically, that pulls in the broader state statutory definition rather than creating a new one here, which means any change to §18998 will affect who counts as a CHW for reporting. For implementers, this avoids duplicative definitions but requires DHCS to map the existing statutory categories to the data elements requested in the analysis.
Annual Review of Managed Care Outreach and Education
DHCS must annually review outreach and education efforts performed by Medi‑Cal managed care plans under §14132.36. This places a specific information obligation on plans as part of DHCS’s broader analysis; plans will need to document not only outreach activity but also outcomes and how outreach reaches priority demographic groups. Compliance teams at plans should prepare to provide structured descriptions and performance metrics for those activities.
Annual Analysis, Publication, and Legislative Submission
The department must conduct an annual analysis of the CHW benefit, publish it on its website, and submit it to the Legislature per Government Code §9795. The bill sets a firm first‑report deadline (July 1, 2027), creating an implementation milestone. DHCS will be responsible for aggregating incoming data, applying quality controls, and formatting the report for public and legislative audiences.
Capacity and Utilization Assessments
These paragraphs require DHCS to assess CHW capacity (supply) and beneficiary needs (demand), and to analyze how the CHW benefit is being used. The statute separates an overall capacity/needs assessment from utilization specifics: it asks for service‑type frequency, counts of eligible beneficiaries, referral patterns by provider type, and employer‑type breakdowns of CHWs. In practice, DHCS will need to reconcile enrollment files, claims/billing or encounter data, provider rosters, and plan reports to produce these linked metrics.
Demographic Disaggregation
DHCS must disaggregate both CHW workforce and beneficiary service data by geography, race, ethnicity, language, age, and other sociodemographic factors and, where applicable, by managed care plan. The explicit request for workforce diversity metrics (racial, ethnic, age, regional, linguistic) signals an equity focus: the department must show how well CHWs reflect the populations they serve. Implementation will require clear category definitions and harmonized fields from multiple reporting entities.
Reimbursement Reporting
The statute compels DHCS to report aggregate Medi‑Cal reimbursement dollars tied to CHW services, including totals paid to providers and supervising entities. That will require coding CHW services consistently in billing or encounter data, and determining which payments count as CHW reimbursement versus other supporting services. For auditors and budget analysts, this line item creates a directly traceable expenditure metric for CHW policy.
Statistical Significance Requirement
Demographic data published in the report must be 'statistically significant.' The bill does not define the statistical test or thresholds, leaving DHCS to adopt a methodology (sample size rules, suppression rules, confidence intervals). This requirement aims to avoid misleading small‑cell disclosure but will force the department to publish a clear methodological appendix and potentially suppress granular results in low‑volume areas.
Privacy Protections — No PII
All collection, submission, publication, and reporting must exclude personally identifiable information. DHCS will need to ensure that linking across datasets does not reidentify beneficiaries or CHWs, and that any public tables comply with HIPAA and state privacy rules. This limits the granularity of publicly released data and increases the importance of rigorous de‑identification and disclosure‑avoidance techniques.

Who Benefits
- Limited‑English and underserved Medi‑Cal beneficiaries — the mandated disaggregation by language, race, region, and age aims to surface gaps in CHW reach and could lead to targeted improvements in outreach and service design for these groups.
- Community health workers and workforce advocates — the data on CHW counts, employer types, and reimbursement creates visibility into the workforce, which advocates can use to argue for training, certification, or funding to expand capacity.
- Community‑based organizations (CBOs) and prospective CHW employers — CBOs will gain evidence about unmet demand and reimbursement flows that can strengthen contracting negotiations with plans and counties.
- DHCS and state policymakers — the regular reports supply an empirical basis for workforce planning, budget requests, and potential changes to Medi‑Cal payment or contracting strategies.
- Medi‑Cal managed care plans — plans will get structured feedback on their outreach effectiveness and utilization patterns, enabling them to adjust network strategies and outreach investments.
Who Bears the Cost
- Department of Health Care Services — DHCS must aggregate, validate, and publish complex, disaggregated datasets and set statistical methodologies without a funding provision in the statute; that translates into staff time and IT costs.
- Medi‑Cal managed care plans and providers (including small CBOs) — plans and providers must supply the data DHCS needs, which may require changes to reporting systems, data collection practices, and staff training.
- Community‑based organizations and small providers — CBOs that contract CHWs may face disproportionate compliance costs to collect demographic data and document CHW activity if their administrative capacity is limited.
- State budget — if the analysis prompts policy changes (expanded CHW funding, higher rates, or workforce programs), the General Fund or county budgets may face increased expenditures.
- Privacy and compliance teams — organizations supplying data will need to invest in de‑identification, data governance, and processes to ensure published outputs meet the bill’s PII exclusion and statistical significance rules.
Key Issues
The Core Tension
The central dilemma is that policy and equity improvements require granular, disaggregated data about who receives CHW services and who provides them, but producing and publishing that level of detail without clear methodological rules or new funding risks imposing heavy reporting burdens, producing unstable or suppressed findings in low‑volume areas, and creating privacy or data‑quality problems that undercut the report’s usefulness.
AB 403 sets up a rigorous reporting framework but leaves several implementation details open. The statute requires that demographic cells published be 'statistically significant' but does not specify thresholds, suppression rules, or which statistical tests DHCS should use.
That vagueness creates a choice between conservative suppression that reduces the report’s utility in low‑volume regions and looser rules that risk unstable estimates. DHCS will also need to define and operationalize what counts as reimbursement for CHW services and what constitutes a 'supervising entity' to avoid double‑counting or omission in dollar totals.
Data integrity and burden are twin risks. The analysis assumes access to standardized encounter and employment data across managed care plans, fee‑for‑service claims, and diverse employers (CBOs, clinics, hospitals).
In reality, those data sources use different codes, payroll models, and personnel records, so DHCS must create a feasible crosswalk and validation process. Small CBOs with limited administrative systems may produce incomplete data, skewing geographic and demographic findings.
Finally, the bill requires DHCS to estimate the number of contracted CHW entities or workers needed to meet demand — an inherently judgmental estimate that will depend on utilization assumptions, service intensity definitions, and policy choices about acceptable service levels.
