AB 1126 requires the Department of Health Care Services (DHCS) to ensure that providers who are not in a Medi‑Cal managed care plan’s network do not face administrative requirements materially greater than billing those same services to the Medi‑Cal fee‑for‑service system when Medi‑Cal is the payer of last resort. The bill also prevents DHCS or plans from forcing fee‑for‑service providers to sign network contracts as a precondition to billing managed care plans for allowable Medi‑Cal costs (Medicare is excluded), while allowing plans to require narrow, specific letters of agreement in situations like prior authorization or continuity of care.
The measure directs DHCS to clarify billing conditions through guidance, regulations, and enforcement as needed, to provide enrollee education on coordinating coverage when requested, and to report annually to state health committees from 2027 through 2030. Implementation is explicitly subject to necessary federal approvals and availability of federal financial participation.
At a Glance
What It Does
The bill bars managed care plans from imposing substantially higher administrative hurdles on non‑contracted providers seeking Medi‑Cal payment when Medi‑Cal is payer of last resort and stops plans from requiring those providers to join networks to bill for allowable Medi‑Cal costs (excluding Medicare). It permits plans to require limited letters of agreement in cases such as prior authorization or continuity of care and charges DHCS with issuing guidance, rules, and enforcement.
Who It Affects
Medi‑Cal fee‑for‑service providers who treat enrollees with other health coverage, Medi‑Cal managed care plans (including their contracting and claims teams), enrollees who hold additional coverage besides Medi‑Cal, and DHCS as the implementing and enforcement agency.
Why It Matters
The change shifts where billing disputes and administrative friction occur: from forcing providers into networks toward resolving payment between non‑contracted providers and plans. That has concrete implications for network strategy, provider cash flow, plan payment risk, and how DHCS monitors coordination between payer types.

What This Bill Actually Does
AB 1126 addresses a specific problem: when a Medi‑Cal enrollee also has other health coverage, Medi‑Cal serves as the payer of last resort. The bill ensures that a provider who is not in the enrollee’s managed care plan network and who bills the plan for Medi‑Cal‑allowable costs (costs remaining after the other insurer pays) will not face administrative demands that are materially greater than the administrative process for billing Medi‑Cal fee‑for‑service.
In short, non‑network providers get a comparable billing pathway to the FFS system for these residual Medi‑Cal claims.
The bill goes further to say that providers participating in Medi‑Cal fee‑for‑service cannot be forced to sign network contracts simply to bill a managed care plan for allowable Medi‑Cal costs, but it carves out two narrow exceptions where a managed care plan may require a letter of agreement (LOA). First, if a covered service requires prior authorization, or if the other insurer doesn’t cover a service that the plan does, the plan may request an LOA that sets payment and service terms; absent that LOA, providers risk being responsible for amounts that exceed the Medi‑Cal FFS rate or for limits on number/duration of services.
Second, the plan may require an LOA when the enrollee is entitled to continuity of care or completion of covered services under existing state continuity rules.To operationalize these changes, the bill tasks DHCS with clarifying conditions for billing managed care plans by non‑contracted providers—through updated regulations, plan and provider guidance, augmented reporting, and enforcement where necessary. The department is also expected to provide educational resources to enrollees who request help coordinating Medi‑Cal with other coverage.
The bill requires DHCS to brief the state Assembly and Senate health committees annually from 2027 to 2030 on implementation effectiveness, and it allows DHCS to use non‑regulatory instruments (all‑county letters, plan letters, bulletins) to implement the section. Finally, the statute is conditioned on obtaining any necessary federal approvals and on federal financial participation being available.
The Five Things You Need to Know
A provider in the Medi‑Cal fee‑for‑service delivery system may bill a Medi‑Cal managed care plan for Medi‑Cal allowable costs when Medi‑Cal is the payer of last resort without being required to join the plan’s network; Medicare is explicitly excluded from this rule.
DHCS must ensure that administrative requirements imposed on non‑contracted providers billing managed care plans are not significantly greater than those for billing Medi‑Cal fee‑for‑service.
A managed care plan may require a letter of agreement for services that need prior authorization or for services covered by the plan but unpaid by the other insurer; without an LOA, the provider may be responsible for billed amounts that exceed the Medi‑Cal FFS rate.
DHCS is authorized to update regulations, issue guidance, increase reporting, and take enforcement action to clarify billing conditions, and must report annually to the Assembly and Senate health committees from 2027 through 2030 on implementation.
Implementation is subject to obtaining necessary federal approvals and the availability of federal financial participation, and DHCS may use all‑county letters, plan letters, or similar non‑regulatory instruments to implement the law.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Parity of administrative requirements for non‑contracted providers
This subsection directs DHCS to make sure that when Medi‑Cal is the payer of last resort, a provider who is not contracted with a managed care plan and who bills the plan for allowable Medi‑Cal costs is not saddled with administrative processes that are materially more burdensome than billing those same costs under Medi‑Cal fee‑for‑service. Practically, DHCS must identify which administrative tasks (claims forms, documentation, prior‑auth workflows, appeals) must be held to FFS standards or simplified when applied to these managed care billing situations.
Prohibition on requiring network contracts (excluding Medicare)
This clause prevents managed care plans from conditioning the right to bill for Medi‑Cal allowable costs on a provider signing an in‑network contract, but it only applies to providers participating in the Medi‑Cal FFS system and explicitly excludes cases involving Medicare. The practical effect: most non‑contracted FFS providers have a statutory route to present residual Medi‑Cal claims to plans without surrendering contract negotiation leverage to obtain access to a plan’s claims system.
Letters of agreement for prior‑auth and uncovered services
When a covered service requires prior authorization, or when the enrollee’s other coverage does not cover a service that the managed care plan does, the plan may require a letter of agreement (or similar) with the non‑contracted provider. The LOA functions as a limited payment/service agreement: it can set that the provider accept the Medi‑Cal FFS allowable rate and related service limits. The section also references Section 14019.4 to make clear that providers cannot pass excess charges to the enrollee even if a plan denies payment beyond the FFS rate.
LOAs for continuity of care and completion of services
If an enrollee meets state continuity‑of‑care rules (Health & Safety Code §1373.96), the managed care plan may require an agreement with the non‑contracted provider to continue or finish covered services. This creates a narrow pathway to preserve ongoing care while letting the plan set terms for those one‑off arrangements, which is intended to balance patient continuity with plan oversight.
DHCS authority, reporting, and implementation conditions
DHCS is empowered to clarify billing conditions by updating regs, issuing guidance, increasing reporting, and enforcing compliance. The department must provide educational resources to enrollees who ask for help coordinating coverage and must report annually to the Assembly and Senate health committees from 2027 through 2030 on how the section is working. The statute allows DHCS to implement the policy via all‑county letters, plan letters, or bulletins (bypassing formal rulemaking) and conditions the entire section on obtaining any needed federal approvals and the availability of federal financial participation.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Medi‑Cal enrollees with other health coverage (excluding Medicare) — they can keep receiving care from non‑network providers without forcing that provider into a network or increasing the risk of balance billing, which supports continuity of care.
- Non‑contracted Medi‑Cal fee‑for‑service providers (clinics, private physicians) — gain a statutory pathway to seek payment from managed care plans for residual Medi‑Cal costs without surrendering to network contracts, improving potential cash flow for services otherwise at risk of nonpayment.
- Safety‑net clinics and community providers — often operating in FFS, these organizations receive clearer authority to present claims to plans for uncovered amounts, reducing pressure to sign contracts that might narrow their payer mix.
- Enrollee navigators and care coordinators — the bill’s requirement for DHCS educational resources creates a more explicit role and resource base for helping dual‑coverage enrollees coordinate benefits and understand continuity rights.
Who Bears the Cost
- Medi‑Cal managed care plans — face increased payment exposure and potential administrative work to process claims from non‑contracted providers, to negotiate LOAs, and to defend payment denials; plans may also face tighter cash‑flow pressure.
- Department of Health Care Services — must draft guidance, potentially amend regs, increase oversight and reporting, and manage enforcement and enrollee education with likely resource implications.
- Providers without LOAs — while many benefit, providers that proceed without an LOA risk being held responsible for billed amounts that exceed the Medi‑Cal FFS rate; smaller providers may absorb unpaid balances or accept FFS rates that undercompensate them.
- Managed care contracting teams and in‑network providers — networks could see their leverage and volume shift if non‑contracted providers are able to capture services that would otherwise go to in‑network clinicians, with downstream competitive and financial effects.
Key Issues
The Core Tension
The central dilemma is between improving patient access and preserving continuity of care versus protecting managed care plans’ ability to manage networks, control utilization, and predict costs: easing providers’ access to plan payment reduces one barrier to care but also transfers payment risk and administrative friction to plans and the state, with no simple, neutral way to satisfy both objectives fully.
The statute leaves several operational questions unresolved. It forbids administrative requirements that are “significantly in excess” of FFS processes but does not define that phrase or set an objective standard, leaving DHCS with discretion that may produce uneven compliance and disputes.
The LOA mechanism opens a practical concern: plans can require LOAs in limited situations, but LOAs might effectively become substitute contract terms or gateways to deny claims if plans use them to impose restrictive payment or documentation conditions.
Federal Medicaid managed care rules and Medicaid’s payer‑of‑last‑resort doctrine intersect here. Because the provision is conditioned on federal approvals and federal financial participation, DHCS will have to reconcile state‑level flexibilities with CMS expectations about managed care plan responsibilities and enrollee protections.
Using non‑regulatory instruments (all‑county letters, plan letters) speeds implementation but can reduce public notice and comment, increasing the risk of legal challenges or practical confusion at the provider level. Finally, the bill shifts some administrative burden to plans and DHCS; absent dedicated resources, enforcement, timely claims processing, and effective enrollee education could lag, undermining the bill’s intent.
