Prior authorization remains a significant administrative issue for California physicians as new state requirements move health plans toward greater transparency and oversight of authorization decisions. The changes are designed to provide regulators with more information about which services are subject to authorization, how frequently requests are approved or modified, and where authorization requirements may be creating unnecessary administrative barriers.
A major development is Senate Bill 306, which took effect July 1, 2026. The law requires health plans regulated by the California Department of Managed Health Care to begin reporting detailed information about covered healthcare services that are subject to prior authorization. The reporting framework is intended to give the state a clearer picture of authorization practices and identify services that are routinely approved.
New Reporting Requirements Change the Regulatory Landscape
SB 306 requires covered health plans to report information concerning services subject to prior authorization, including approval and modification rates. Plans must also provide information concerning the requested and authorized duration, frequency, or level of care associated with authorization determinations.
The law also addresses delegated entities. When a health plan delegates authorization decisions to another organization, the plan remains responsible for obtaining the information needed for its state reporting. This creates an additional compliance consideration for plans that rely on medical groups, utilization-management organizations, or other delegated entities to conduct authorization reviews.
The reporting deadline is December 31, 2026. The Department of Managed Health Care is then required to evaluate the information and identify services with authorization approval rates of at least 90 percent. The state is scheduled to publish a list of services for which health plans cannot require prior authorization by July 1, 2027, following stakeholder consultation.
What the Changes Mean for Physicians
For physicians, the significance extends beyond the reporting obligations imposed on health plans. Better regulatory visibility into authorization patterns could eventually reduce repetitive requests for services that are consistently approved.
Physicians frequently encounter authorization requirements while coordinating imaging, procedures, specialty services, medications, and other forms of treatment. When an authorization process requires extensive documentation or repeated submissions, clinical staff may spend substantial time managing administrative requirements instead of supporting direct patient care.
California’s new reporting framework creates the possibility of a more targeted approach. If state data demonstrates that a particular service is routinely approved, the service could ultimately be considered for removal from the authorization process. That does not happen automatically in 2026, however. The state must first collect and evaluate the required information before establishing the future list of services exempt from authorization.
Prior Authorization and Continuity of Care
The policy debate also involves continuity of care. Delays in authorization can affect when patients receive diagnostic testing, procedures, medications, or specialist treatment.
California already maintains requirements concerning timely access to care. The DMHC states that certain urgent appointments can have different access standards depending on whether prior approval is required, illustrating how authorization requirements can intersect directly with the timing of care.
For physicians, this makes accurate documentation and timely communication with health plans particularly important. A practice may have strong clinical justification for a treatment, but authorization workflows can still require specific information before a plan makes its determination.
The regulatory framework also provides avenues for challenging decisions involving medically necessary care. California’s Independent Medical Review system allows eligible disputes involving services denied, modified, or delayed based on medical necessity to receive independent review.
Health Plans Face Greater Accountability
California’s broader regulatory environment demonstrates that health plans are being scrutinized not only for authorization decisions themselves but also for how they respond to complaints and regulatory inquiries.
On September 9, 2026, the DMHC announced an $800,000 fine against Blue Shield of California after finding repeated failures involving responses to department inquiries concerning member grievances. The department said the failures delayed resolution of 58 member complaints, including matters involving medically necessary care. Although the enforcement action concerned grievance-system requirements rather than SB 306’s new reporting obligations, it illustrates the department’s continuing focus on health-plan responsiveness and regulatory compliance.
This environment is relevant to physicians because authorization disputes can become part of broader grievance, appeal, and regulatory processes. Accurate records of requests, clinical justification, communications, and plan responses can become important when a treatment decision is challenged.
Physician Practices Should Prepare for Continued Changes
The immediate responsibility under SB 306 rests primarily with covered health plans, but physician practices should still monitor how the reporting system develops. Changes to authorization requirements could affect referral workflows, clinical documentation, scheduling, and communication with payers.
Practices may also benefit from identifying which services generate the greatest authorization workload. Tracking repeated requests, delays, denials, and additional documentation demands can provide physicians and practice administrators with useful information about where administrative burden is concentrated.
The state’s eventual identification of high-approval services could become especially important. If frequently approved services are removed from prior authorization requirements, physicians may experience fewer administrative steps for routine care. At the same time, services that remain subject to prior authorization will likely continue requiring careful compliance with payer-specific procedures.
California Moves Toward More Data-Driven Authorization Policy
California’s prior authorization reforms represent a shift toward greater regulatory visibility into how health plans manage access to covered services. Instead of relying exclusively on individual complaints about authorization delays, the state is establishing a broader data framework that can reveal approval patterns across services and plans.
For physicians, the most important developments will come as health plans submit their required data and the DMHC evaluates which services are consistently approved under prior authorization. The resulting information could influence future decisions about whether certain prior authorization requirements remain necessary.
The process is therefore still developing. The July 2026 implementation of SB 306 is an important regulatory milestone, but the larger policy effects are expected to emerge through the December 2026 reporting process and the state’s planned 2027 review.
Physicians and practice leaders should continue monitoring these developments because changes to prior authorization requirements can directly affect administrative workload, treatment timing, clinical workflows, and patient access. The objective of reducing unnecessary administrative barriers will ultimately depend on how effectively the new reporting framework translates into practical changes in healthcare delivery.
