AB 1048 revises Section 4610 to clarify when utilization review (UR) applies to medical treatment in California workers’ compensation claims. The bill allows emergency care and other medical treatment for an accepted body part or condition rendered within the first 30 days after the date of injury to be authorized without prospective utilization review when provided by a medical provider network (MPN) physician, health care organization physician, predesignated physician, or employer‑selected physician; it also sets out a specific list of services that remain subject to prospective UR during that 30‑day window.
Beyond the 30‑day rule, the bill imposes operational obligations: physicians must submit required reports and a complete request for authorization within narrow deadlines; employers must maintain accredited UR processes, a medical director, public disclosure of UR policies, and telephone access for peer‑to‑peer review; the administrative director gains oversight authority, mandatory electronic reporting is required, and administrative penalties may be assessed for noncompliance. For employers and treating providers this changes the balance between rapid access to initial care and downstream controls like retrospective review, accreditation, and possible removal from exemption status.
At a Glance
What It Does
The bill authorizes emergency and accepted-condition medical treatment within 30 days of injury without prospective utilization review when provided by specified treating physicians or employer-selected facilities, but it preserves prospective UR for a defined list of higher‑risk services (e.g., nonemergency surgery, imaging beyond x‑ray, psych care, DME over $250, most pharmaceuticals). It also requires accredited UR processes, timelines for decisions and communications, mandatory electronic reporting to the Division of Workers’ Compensation, and allows employers to use retrospective review to remove providers who repeatedly ignore the medical treatment utilization schedule.
Who It Affects
Directly affected parties include treating physicians in medical provider networks or predesignated/employer‑selected roles, employers and their insurers or claims administrators, utilization review organizations, and injured workers who receive initial treatment. The administrative director and Division of Workers’ Compensation acquire new oversight responsibilities for accreditation, rulemaking, and enforcement.
Why It Matters
The bill formalizes a time-limited zone of expedited access to care while preserving employer tools to control cost and consistency with the medical treatment utilization schedule and drug formulary. Compliance officers, MPN administrators, and provider groups must revise intake, reporting, and UR workflows to meet short submission deadlines, accreditation standards, and electronic reporting requirements.

What This Bill Actually Does
AB 1048 defines utilization review as the full set of pre‑, concurrent, and retrospective medical necessity review functions that approve, modify, or deny physician treatment recommendations under California workers’ compensation. The statute creates a clear operational rule: for dates of injury on or after January 1, 2018, emergency care and any medical treatment for a compensable body part or condition delivered within 30 days of the initial injury by an MPN physician, health care organization physician, predesignated physician, or employer‑selected physician are authorized without prospective utilization review, provided the care follows the medical treatment utilization schedule.
The bill draws an explicit exception list of services that remain subject to prospective utilization review even during that 30‑day window. That list covers most pharmaceuticals (unless exempted or covered by the formulary), nonemergency surgery and related perioperative services, psychological treatment, home health, imaging beyond x‑ray, durable medical equipment whose combined value exceeds $250 by the official fee schedule, electrodiagnostic testing, and any additional categories the administrative director defines by rule.
For these services, employers or their UR agents may require prior authorization under the usual UR procedures.Operationally the statute imposes tight deadlines and reporting obligations on treating physicians and claims administrators. When treatment is provided under the 30‑day exemption, the treating physician must submit the Section 6409 report and a complete request for authorization within five days of the initial visit; employers may remove a physician from the exemption for failing to do so.
UR decisions have specified timeframes: most prospective or concurrent determinations must be made within five normal business days of receiving a request and supporting documentation (but no more than 14 days from the physician’s recommendation), imminent‑threat cases must be decided within 72 hours, and communications about final decisions carry 24‑hour and two‑business‑day obligations depending on the review type.The bill also strengthens employer and system controls. Employers must operate an accredited UR process governed by written policies and overseen by a designated medical director, disclose procedures publicly, and submit those policies to the administrative director.
The administrative director may review compensation agreements between employers and UR physicians, designate an accreditor (URAC by default until rules are adopted), require electronic reporting of UR documents to the Division of Workers’ Compensation, and assess administrative penalties for violations. Employers keep the ability to perform retrospective review to check adherence to the medical treatment utilization schedule; repeated divergence can trigger provider removal from the 30‑day exemption and supply grounds for change‑of‑physician petitions or termination from an MPN.
The Five Things You Need to Know
The bill authorizes emergency and accepted-condition treatment within 30 days of injury without prospective utilization review when delivered by an MPN physician, health care organization physician, predesignated physician, or employer‑selected physician, but requires the treating physician to submit the Section 6409 report and a complete authorization request within five days of the initial visit.
A specified list of services remains subject to prospective UR within the 30‑day window: most pharmaceuticals (unless exempt or on the formulary), nonemergency surgery (and perioperative care), psychological services, home health, imaging beyond x‑ray, DME when combined value exceeds $250, and electrodiagnostic testing.
Prospective or concurrent UR decisions generally must be issued within five normal business days of receipt of the request and necessary documentation (but no later than 14 days from the physician’s recommendation); imminent‑threat cases must be decided within 72 hours, and certain final decisions require immediate telephone notice plus written follow‑up within 24 hours (concurrent) or two business days (prospective).
Employers must run accredited UR processes (accreditation required by July 1, 2018 with URAC as default until rules are adopted), submit UR policies and procedures to the administrative director, publicly disclose them, and designate an unrestricted‑license medical director to oversee UR decisions.
Employers may conduct retrospective reviews to check consistency with the medical treatment utilization schedule and drug formulary; a demonstrated pattern of nonconforming treatment lets the employer remove a physician or provider from the 30‑day exemption and use the results to seek change‑of‑physician or MPN termination.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Definition of utilization review
This subsection defines utilization review broadly to include prospective, retrospective, and concurrent review of physicians' treatment recommendations for medical necessity under Section 4600. That broad definition sets the scope for the rest of the section: when the statute refers to utilization review it encompasses all points in the care pathway where approval, modification, or denial might occur.
30‑day authorization without prospective UR
For dates of injury on or after January 1, 2018, the bill authorizes emergency treatment and other accepted-condition care provided within 30 days of the initial injury by specified treating physicians or employer‑selected facilities without prospective UR, provided the care follows the medical treatment utilization schedule. It also creates a prompt-documentation requirement: if the employee is treated under an MPN, HCO, predesignated, or employer‑selected physician, that physician must submit the Section 6409 report and a complete authorization request within five days of the initial visit — a compliance trigger that employers can enforce by removing the exemption for noncomplying physicians.
Services still subject to prospective UR during first 30 days
This subsection enumerates categories of care that remain subject to prospective UR even during the 30‑day window. The list includes most pharmaceuticals (except those expressly exempted or covered by the formulary), nonemergency inpatient and outpatient surgery, psychological treatment, home health, imaging beyond x‑ray, DME exceeding $250 in combined official fee schedule value, electrodiagnostic studies, and any other categories the administrative director defines by rule. Practically, providers and UR vendors must route authorization workflows for these services even when other contemporaneous care flows without prior review.
Billing timelines, emergency treatment definition, and retrospective review consequences
The bill requires standard claims submission timelines for payment requests (30 days for most services and 180 days for emergency services provided in licensed general acute care hospitals as defined by state law). It authorizes employers to perform retrospective UR of 30‑day‑exempt treatments solely to check consistency with the treatment utilization schedule and formulary; if retrospective review reveals a pattern of nonconformity, the employer may remove a physician or provider from the exemption and notify them. The results of retrospective review may be used as grounds for change‑of‑physician petitions or to remove a provider from an MPN.
UR process requirements, medical director, and anti‑incentive rules
Employers must establish UR processes (directly or via insurer/contractor) governed by written policies that ensure decisions align with the medical treatment utilization schedule and formulary. The employer, insurer, or UR entity must employ or designate a medical director with an unrestricted California medical license to oversee the process. The statute prohibits financial incentives tied to denial/modification rates and restricts referral of UR services to entities where an insurer or TPA has a financial interest unless prior written disclosure is given; the administrative director can review compensation and contracts and treat disclosed materials as confidential.
Accreditation, submission and public disclosure of UR policies, and criteria standards
A UR process that modifies or denies requests must be accredited by an independent nonprofit by July 1, 2018 and maintain active accreditation while providing UR services; the administrative director will prescribe accreditation criteria and may designate URAC until rules are adopted. Employers must submit their UR process descriptions and written policies to the administrative director for approval and make them available to employees and the public via posting. Criteria used in UR must be developed with input from actively practicing physicians, kept consistent with the utilization schedule and formulary, evaluated annually, disclosed when used to deny/modify care, and made available on request.
Decision timeframes, communication requirements, appeals, and operational access
The bill sets precise timeframes: typical prospective/concurrent decisions must issue within five normal business days from receipt of the request and documentation (but not later than 14 days from the physician’s recommendation); retrospective denials must be communicated within 30 days after receiving necessary information; imminent threat cases must be decided within 72 hours. Final decisions require immediate phone notification plus written follow‑up (24 hours for concurrent; two business days for prospective). The statute preserves peer‑to‑peer discussion rights, prevents discontinuation of care during concurrent review until a care plan is agreed, and ties dispute resolution to existing statutory routes such as Section 4610.5 or Section 4062. Employers must also maintain telephone access during California business hours to support authorization requests and peer‑to‑peer dialogue.
Electronic reporting, enforcement, and mandated evaluation
The administrative director must develop mandatory electronic reporting of documents related to every utilization review, with regulations specifying documents, formats, and timeframes; the Division of Workers’ Compensation will administer the system. The administrative director may assess administrative penalties (with notice and hearing) for failures to meet timeframes or other statutory requirements, with penalties deposited into the Workers’ Compensation Administration Revolving Fund. The bill also requires the administrative director to contract with an independent research organization to evaluate early provision-of-care impacts and report findings to specified legislative committees.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Injured workers — gain faster initial access to emergency and accepted‑condition care because many treatments in the first 30 days do not require prior authorization, reducing administrative delay for early interventions.
- Treating physicians in MPNs, predesignated physicians, and employer‑selected providers — receive temporary autonomy to deliver initial care without prior authorization, subject to the five‑day reporting requirement, which simplifies early clinical decision‑making.
- Employers and insurers — retain tools to control costs and consistency with the medical treatment utilization schedule through prospective UR for higher‑risk services, retrospective review authority, and the ability to remove providers who repeatedly deviate from the schedule.
- Regulators and policymakers — the administrative director and DWC gain structured data via mandatory electronic reporting and an evaluation contract to assess early‑care outcomes, improving oversight and policy refinement.
Who Bears the Cost
- Employers, insurers, and claims administrators — must implement or contract for accredited UR processes, designate medical directors, publicly post policies, and comply with new electronic reporting and potential administrative penalties, increasing operational and compliance costs.
- Utilization review organizations and vendors — face accreditation compliance, limits on financial relationships, and administrative director scrutiny of contracts and compensation arrangements, which may limit certain business models.
- Treating physicians and provider clinics — must meet tighter documentation and submission deadlines (including the five‑day Section 6409 report rule) and face the risk of losing exemption status or MPN privileges if retrospective review finds nonconforming care.
- Division of Workers’ Compensation/administrative director — will absorb rulemaking, accreditation oversight, confidential contract review, electronic reporting administration, and enforcement functions, creating workload and resourcing demands.
Key Issues
The Core Tension
The central dilemma is speed versus control: the bill speeds injured workers’ access to initial care by removing prospective UR for many early treatments, but it simultaneously arms employers and regulators with retrospective policing, accreditation, and penalty tools that can limit provider discretion and raise administrative costs — an arrangement that improves timeliness only if oversight mechanisms are designed and executed without creating new barriers at the point of care.
AB 1048 deliberately tightens the operational regime around initial post‑injury care: it accelerates access by carving out a 30‑day authorization window while simultaneously expanding controls — accreditation, reporting, retrospective review, and penalties — that can limit provider behavior after the fact. That design creates implementation challenges.
Employers and UR vendors must reengineer intake, documentation, and electronic‑submission workflows to meet five‑day and five‑business‑day benchmarks, and the administrative director must write detailed rules and data standards to make the electronic reporting and accreditation requirements workable. Those rulemaking steps will determine how frictionless the 30‑day exemption actually is in practice.
The bill also creates tension between deterrence and access. Retrospective review and removal of a provider from the exemption function as strong enforcement tools to ensure alignment with the medical treatment utilization schedule and formulary, but they also risk chilling appropriate clinical judgment if providers fear post hoc sanctions.
The prohibition on incentives tied to modification/denial rates and limits on referral relationships narrows some cost‑management techniques, but the administrative director’s authority to review contracts and compensation may lead to disputes over proprietary arrangements and confidentiality protections. Finally, the statute contains fixed dates and accreditation deadlines (and references to prior evaluation periods) that will require careful administrative interpretation; the efficacy of the entire scheme depends on clear, timely regulations and adequate funding for DWC enforcement and IT for electronic reporting.
