AB1770 rewrites how disputes between health care service plans and their subscribers or enrollees are handled in arbitration. The bill requires plans to pay arbitrator fees and the plan’s defense costs, mandates a court reporter at hearings, preserves broad discovery rights, and orders detailed, timely reporting and five-year retention of arbitration records with a presumption of public access subject to a narrow sealing test.
The measure is significant for payers, providers, patient advocates, and the Department of Managed Health Care (the director). It reallocates financial responsibility for arbitration, creates a central repository of dispute records for regulator review, and raises immediate implementation questions about privacy protection, administrative burden, and the interaction between these state rules and other arbitration or confidentiality frameworks used in health‑care contracting.
At a Glance
What It Does
The bill requires health care service plans to pay arbitrator fees and the plan’s defense costs while enrollees pay their own costs; it compels the use of a court reporter and preserves subpoena, deposition, and discovery rights. It also requires the assigned arbitrator to report case details to the director within 30 days and mandates five-year retention by plans and the department.
Who It Affects
Health care service plans regulated under California law, plan enrollees and subscribers, health care providers named in disputes, arbitrators and arbitration administrators, and the Department of Managed Health Care (the director) as the receiving authority for reports and records.
Why It Matters
AB1770 rebalances incentives in plan-enrollee disputes by shifting major costs to plans and elevates regulatory oversight through mandatory reporting and public posting. That combination may change settlement behavior, increase administrative costs for plans and the regulator, and create friction between transparency and patient privacy protections.

What This Bill Actually Does
AB1770 creates a specific arbitration regime for disputes between a health care service plan and its subscribers or enrollees. The core cost rule assigns responsibility for the arbitrator appointed under Section 1373.20 to the health plan and also makes the plan liable for defense costs; enrollees remain responsible for their own costs.
The arbitrator is tasked with controlling costs during the proceeding, including limiting expert-witness use to what the arbitrator considers reasonable.
The bill overrides the usual exception in California Code of Civil Procedure section 1282.5 by requiring a court reporter to be present for arbitration, and it makes the plan pay for that reporter to capture the proceedings, exhibits, and the arbitrator’s written decision rationale. Parties retain subpoena authority under CCP 1282.6 and discovery and deposition rights under CCP 1283.05, signaling that these arbitrations will closely resemble court litigation in terms of fact development.For oversight and transparency, the assigned arbitrator must deliver a complete report to the director within 30 days of the arbitration’s conclusion.
The report must identify the parties, enumerated participants (including providers, plan employees, and facilities), the arbitrator’s name, the award amount if any and the reasons for the award or denial, the complete written decision under Section 1373.20, and a list of all evidence submitted. Plans must preserve all arbitration-related documents for five years and provide copies to the director within 30 days of case closure; the director will likewise retain records for five years.The bill sets a presumption that these records are public, but it includes two limiting devices.
First, the department must not make patient-identified medical information public without written consent, consistent with privacy law. Second, a party can ask a court to seal department-obtained records, but only under a strict five-factor test that requires an overriding interest, likely prejudice, narrow tailoring, and the absence of less restrictive alternatives.
The director may also disclose provider identity consistent with Business and Professions Code section 803.1. Finally, AB1770 applies to arbitrations commencing on or after February 1, 2027.
The Five Things You Need to Know
The health care service plan must pay the arbitrator appointed under Section 1373.20 and all defense costs the plan incurs; enrollees pay only their own costs.
Arbitrations must have a court reporter despite CCP 1282.5, and the plan pays the reporter to record proceedings, exhibits, and the arbitrator’s decision rationale.
The arbitrator must submit a detailed report to the director within 30 days of case closure that includes party identities, award amounts with reasons, the arbitrator’s written decision, and a list of all evidence submitted.
All arbitration records must be preserved by the plan and the director for five years; records are presumed public unless a court grants sealing under a five-part, narrowly tailored test.
Parties retain subpoena (CCP 1282.6), deposition, and discovery rights (CCP 1283.05) in arbitration, making pre-hearing fact development and evidence exchange broadly available.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Cost allocation and arbitrator cost‑control
This subsection assigns financial responsibility for the arbitrator and the plan’s defense costs squarely to the health care service plan, while leaving each enrollee responsible for their own costs. It also gives the arbitrator affirmative authority to control costs during the proceeding, explicitly including limits on expert witness usage. Practically, plans will face higher direct arbitration expenses, while arbitrators gain a procedural lever to contain litigation-style cost escalation.
Court reporter, subpoenas, and discovery rights
Despite the ordinary exception in CCP 1282.5, AB1770 mandates a court reporter and requires plans to pay for that reporter to create a record of the hearing, exhibits, and the arbitrator’s decision rationale. The bill preserves subpoena authority under CCP 1282.6 and discovery/deposition rights under CCP 1283.05, meaning parties can develop the record similarly to civil litigation. Expect longer, more document-intensive arbitrations and higher administrative bills tied to reporter, transcription, and discovery costs.
Noninterference with provider contract rules (Section 1295)
This short provision clarifies that AB1770 does not override Section 1295 of the Code of Civil Procedure, which relates to contracts for medical services with health care providers. The clause preserves existing legal rules that protect provider-contract relations from being displaced by this arbitration regime, a useful signal that the Legislature did not intend to unsettle established provider-contract enforcement mechanisms.
Mandatory reporting to the director and five‑year preservation
The assigned arbitrator must file a complete report with the director within 30 days of arbitration closure, listing parties, award amounts and reasons, arbitrator identity, involved providers and facilities, the complete written decision under Section 1373.20, and all evidence submitted. Plans must preserve the full record of the arbitration for five years and supply a copy to the director within 30 days of closure or withdrawal. The director also retains the materials for five years. That creates a predictable document flow for regulator review but will require plans to implement new record-management and transfer processes.
Public access, sealing standard, and limited privacy protections
AB1770 presumes department-held arbitration records are public and directs the director to post records and discovery materials on the department’s website, subject to the statute’s privacy limitations. Patient-identified medical information cannot be made public without written consent, and parties may seek a court order to seal records only by meeting a five-factor test that demands an overriding interest and narrow tailoring. The bill also permits the department to disclose provider identities consistent with Business and Professions Code section 803.1. Operationally, the department will need redaction protocols and a legal process for handling sealing motions.
Applicability and effective date
The section makes these rules apply to all disputes arbitrated on or after February 1, 2027. That gives plans, arbitrators, and the regulator a predictable start date to prepare compliance systems, though it also compresses the lead time for creating reporting workflows and public posting mechanisms.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Enrollees and subscribers — Benefit from reduced upfront barriers to arbitration because plans pay arbitrator fees and plan defense costs, and from increased transparency into arbitration outcomes and evidence.
- Consumer advocates and researchers — Gain access to a richer, centralized dataset of arbitration decisions and evidence for oversight, trend analysis, and policy advocacy.
- Attorneys representing enrollees — Obtain fuller discovery rights and a recorded transcript of proceedings (via court reporter), which improves appellate, settlement, and case-preparation options.
- The Department of Managed Health Care (the director) — Receives structured reports and records that enable regulatory oversight, trend identification, and enforcement targeting.
Who Bears the Cost
- Health care service plans — Must pay arbitrator fees, the plan’s defense costs, court reporters, and additional discovery/administrative expenses; these costs may translate into higher operating expenses or premiums.
- Arbitration administrators and arbitrators — Face explicit cost‑control duties and additional administrative requirements (detailed written decisions and report filings), potentially increasing procedural complexity and oversight exposure.
- The Department of Managed Health Care — Must receive, store, redaction‑review, and publish large volumes of records, creating administrative and IT costs if not separately funded.
- Health care providers and facilities named in disputes — May see reputational impact from public disclosure and incur time/costs responding to subpoenas or participating in discovery that previously might have been limited.
Key Issues
The Core Tension
The bill trades increased access and regulatory transparency against patient privacy and administrative burden: it pushes information and cost burdens onto health plans and the regulator to improve enrollee access and public oversight, but doing so creates real privacy, procedural, and funding trade-offs that the statute leaves to implementing actors to resolve.
AB1770 creates useful transparency and access guardrails but raises hard implementation questions. The statute presumptively opens arbitration records to the public while also promising to withhold patient-identified medical information without written consent.
The bill does not specify redaction standards, who performs redaction before public posting, or how to reconcile disclosures the department is authorized to make under Business and Professions Code section 803.1 with HIPAA and other confidentiality obligations. These gaps will force the department and plans to adopt operational rules and redaction protocols that balance legal risk and the statute’s transparency aims.
The bill also sharpens procedural tensions inside arbitration. Requiring plans to pay arbitrator fees and defense costs shifts financial incentives toward greater use of arbitration by claimants, but it may also prompt plans to respond with more aggressive discovery, litigate on procedural grounds, or seek contract language to limit exposure where possible.
Giving arbitrators cost-control authority raises questions about how arbitrators will exercise that discretion across case types, especially in complex medical-negligence or billing disputes where expert testimony is central. Finally, the statute foresees no administrative funding for the director’s new docketing, retention, and public-posting duties, creating a potential unfunded mandate that could delay implementation or require reallocation of departmental resources.
