California AB 40: Hospital APOT Rules, Deadlines, and Penalties

California’s AB-40 requires every general acute care hospital with an emergency department to keep ambulance patient offload time (APOT) within a local standard that cannot exceed 30 minutes, 90 percent of the time, and to file a written reduction protocol with the Emergency Medical Services Authority (EMSA) describing how the hospital will meet it.¹ When a hospital exceeds that standard, EMSA directs it to activate the protocol and joins biweekly coordination calls with hospital and EMS leadership until performance improves.

The 30-Minute APOT Standard Hospitals Must Meet

APOT is the interval between an ambulance’s arrival at the emergency department and the moment the patient is physically transferred to an ED gurney, bed, chair, or other location where the hospital assumes responsibility for care.² Before AB-40, California had no uniform ceiling on that handoff time.

AB-40 does not set the hospital’s standard directly. It requires each local EMS agency (LEMSA) to adopt one, and caps that standard at 30 minutes, 90 percent of the time.¹ A LEMSA may adopt a tighter number if local conditions allow, and may develop it with input from hospitals, fire departments, exclusive employee representatives, and EMS providers. Hospitals are measured against whatever the LEMSA in their jurisdiction has adopted.

The APOT Reduction Protocol Every Hospital Must File

Every general acute care hospital with an emergency department has to develop an APOT reduction protocol spelling out how it will stay within the LEMSA standard. The protocol must be built in consultation with ED staff and any exclusive employee representatives, and it must address mechanisms to improve hospital operations and reduce APOT.³

The protocol is filed with EMSA, and any revisions are reported annually. It is not a static document. EMSA tracks each hospital’s APOT monthly, and the protocol becomes the playbook the hospital is ordered to activate once performance slips.³

How Offload Times Are Measured

Compliance is tracked through the California Emergency Medical Services Information System (CEMSIS). AB-40 required EMSA to build an electronic signature function into CEMSIS that captures two timestamps: when the ambulance arrives at the hospital and when transfer of care actually occurs.¹ The signature is collected at the point of physical transfer, when the ambulance crew gives its report to hospital staff, and it must note the arrival time at the hospital.³

Those records feed a monthly audit. When a hospital flags a disputed record, the LEMSA convenes a review with the hospital and the EMS provider, and corrected records are re-uploaded into CEMSIS.⁴ The audited monthly totals are what EMSA uses to judge compliance.

What Happens When a Hospital Exceeds the Standard

If a hospital’s audited APOT for the preceding month exceeds the LEMSA standard, EMSA reports the exceedance to the LEMSA and to the Commission on Emergency Medical Services, and directs the LEMSA to notify every EMS provider in the jurisdiction.³

The hospital is then directed to immediately implement its APOT reduction protocol, no later than five business days after notification. EMSA convenes biweekly coordination calls with hospital administration, ED leadership, hospital employees, the LEMSA, and the affected EMS transport providers.⁴ Those meetings continue as the mechanism for keeping pressure on operational changes, with the Commission’s involvement adding state-level visibility.

Penalties for Noncompliance

AB-40’s main enforcement tool is administrative: notification, mandatory protocol activation, and the biweekly EMSA coordination process. The law does not impose specific fines tied to exceeding the APOT standard.

The criminal backstop sits in the underlying statute. AB-40 adds requirements to California’s Emergency Medical Services System and Prehospital Emergency Medical Care Personnel Act, and violations of that act or regulations adopted under it are punishable as misdemeanors under existing law.⁵ By expanding the act’s scope, AB-40 broadens the conduct that could technically support a misdemeanor charge, though that route functions as a backstop for serious or willful noncompliance rather than a routine response to monthly numbers.

Implementation Deadlines

The compliance calendar built into AB-40 was staggered:

July 1, 2024: Every LEMSA had to adopt its APOT standard and report it to EMSA.
September 1, 2024: Every general acute care hospital with an emergency department had to have its APOT reduction protocol developed.
December 31, 2024: EMSA had to have the CEMSIS electronic signature system, the audit tool, and emergency regulations in place, and begin monthly APOT monitoring for each hospital.¹

EMSA has since published Title 22 regulation text establishing the statewide standards, protocols, and tools, and re-adopted the emergency regulations in early 2026 while permanent rulemaking continues.⁶ Hospitals that have not revisited their protocol since initial filing should expect their next annual revision to track the current regulation text.

Help for Small Rural Hospitals

EMSA is directed to provide technical assistance and funding, as needed and subject to appropriation, for small rural hospitals and volunteer EMS providers implementing AB-40’s requirements.¹ The requirements themselves still apply, and the funding depends on the state budget actually allocating money for it.
