AB 1637 adds a new section to the Business and Professions Code addressing physician medical documentation. It establishes rules about who may control and alter clinicians’ records and ties those rules to professional enforcement.
The proposal matters to any organization that creates, stores, or supervises clinicians’ documentation: it changes day-to-day workflows for scribes, medical assistants, supervising physicians, and EHR systems, and it potentially increases criminal liability exposure for physicians and entities that rely on delegated documentation practices.
At a Glance
What It Does
The bill adds Section 2266.1, which defines “patient notes” and makes the authoring physician responsible for those notes. It bars alteration, modification, or editing of those notes by anyone other than the authoring physician, subject to specified narrow exceptions.
Who It Affects
Authoring physicians and surgeons, clinicians who create or add to records (including trainees and covering physicians), health systems that use scribes or delegated documentation, and EHR vendors and compliance teams that implement audit trails and editing workflows.
Why It Matters
By codifying control of clinical notes and linking prohibited edits to professional/criminal enforcement, the bill shifts risk toward individual physicians and forces institutions to rework delegation, supervision, and EHR editing capabilities to preserve compliance.

What This Bill Actually Does
AB 1637 inserts a new Section 2266.1 into California’s Business and Professions Code and targets the mechanics of clinical documentation. It begins by identifying the universe of text covered—“patient notes” are the bill’s defined term for notes, after-visit summaries, and diagnosis and treatment plans—and then assigns primary responsibility for those items to the physician or surgeon who authored them.
The core constraint the bill creates is a prohibition on altering or editing an author’s patient notes by anyone other than the authoring physician. The statute, however, carves out three narrow situations where others may alter or add to notes: (1) an authorized individual—such as a scribe or medical assistant—acting under delegation from the authoring physician; (2) a different physician who adds to notes when care has been transferred to them; and (3) a supervising physician who edits the notes of trainees (postgraduate licensees, interns, residents, or postdoctoral fellows) they supervise.
Those exceptions are textual and conditional, so compliance will turn on whether an authorization, transfer of care, or supervisory relationship can be demonstrated in the record.The bill does not create a new civil regime with detailed correction procedures; instead, it places these requirements within the Medical Practice Act framework that already makes violations unprofessional conduct and, unless otherwise specified, a crime. The measure further includes the Legislature’s finding about local costs: because the change expands the scope of criminal violations under state professional law, the bill treats those costs as a state-mandated local program but states no state reimbursement is required under Article XIII B, Section 6.
Practically, health systems and clinicians will need to reconcile these statutory commands with existing institutional policies, EHR audit trails, and routine documentation practices such as templates, shared note-building, and retroactive corrections.
The Five Things You Need to Know
The bill adds new Section 2266.1 to the Business and Professions Code and defines “patient notes” as notes, after-visit summaries, and diagnosis and treatment plans.
It assigns responsibility for patient medical documentation to the authoring physician ‘‘regardless of the clinical setting,’’ making the physician principally accountable even when notes are produced under institutional workflows.
The statute forbids anyone other than the authoring physician from altering, modifying, or editing patient notes, except for three textual exceptions: delegated individuals (e.g.
scribes/medical assistants), a receiving physician after transfer of care, and supervising physicians editing supervised trainees’ notes.
Because the prohibition is placed inside the Medical Practice Act framework, prohibited alterations can trigger professional discipline and are treated as criminalized conduct under existing enforcement provisions, which the bill notes creates a state-mandated local program.
The bill includes a clause asserting no state reimbursement is required for local costs because the change alters the definition or scope of a crime for purposes of Article XIII B, Section 6 of the California Constitution.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Definition of covered documentation
Subsection (a) provides a narrow statutory definition of “patient notes”: the term covers notes, after-visit summaries, and diagnosis and treatment plans. That definitional choice matters because it excludes other record elements (for example, billing codes or administrative metadata) from the statute’s text; compliance teams will need to map this legal definition to their EHR fields to know which items are protected by the new editing limitations.
Authoring physician is responsible for documentation
Subsection (b) makes clear that the physician or surgeon who authors the patient notes bears responsibility for them “regardless of the clinical setting.” This places legal accountability squarely on individual clinicians even when documentation is produced or stored within a hospital, clinic, telehealth platform, or other employer environment, meaning employers cannot rely solely on institutional ownership to shield clinicians from enforcement risk.
Prohibition on edits and three narrow exceptions
Subsection (c) prohibits alteration, modification, or editing of an author’s patient notes by anyone other than that author, but enumerates three exceptions: (1) authorized designees like scribes or medical assistants operating under delegated authority; (2) a physician who adds to notes after an explicit transfer of patient care; and (3) a supervising physician who edits notes of trainees they supervise. Each exception is textual and conditional, meaning institutions must document delegation, transfer-of-care events, or supervisory relationships to rely on them defensibly.
Fiscal statement about mandated local costs
The bill contains a legislative fiscal clause stating that no state reimbursement is required because the only local costs arise from criminal-law changes covered by Article XIII B, Section 6. Practically, this signals the Legislature’s intent that local agencies will bear enforcement and processing costs tied to any new criminal exposure generated by the statutory change.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Patients who need an auditable provenance for their records — the bill makes the source of clinical notes legally traceable to the authoring physician and narrows who may alter those entries, which strengthens claims about note integrity.
- Physicians who want exclusive control over their clinical reasoning — the statute formalizes authorship control, allowing clinicians to prevent others from changing their impressions or plans except in limited, documented circumstances.
- Supervising physicians and training programs — the text explicitly preserves the long-standing supervisory exception, allowing attendings to correct or add to trainees’ notes while keeping that authority within the supervisory chain.
- Compliance officers and record-keeping teams — the statute’s bright-line definition of covered note types gives a concrete starting point for audits, EHR configuration, and policy drafting, reducing interpretive ambiguity about which record elements the law targets.
Who Bears the Cost
- Individual physicians and surgeons — the bill increases individual responsibility and exposure because it ties prohibited editing to the Medical Practice Act’s disciplinary and criminal framework, potentially making clinicians personally liable for unauthorized changes to notes.
- Health systems and clinics that use delegated documentation models — organizations will need to rework policies, delegation agreements, training, and supervision to ensure edits fall within the statute’s exceptions, creating administrative and operational costs.
- EHR vendors and IT teams — systems must support stronger audit trails, granular edit controls, and delegation metadata to demonstrate who entered or edited a note and when; implementing and validating these controls will require development and testing effort.
- Local prosecuting entities and licensing boards — because the bill expands the scope of conduct treated as criminal or unprofessional under the Medical Practice Act, local agencies may face additional enforcement, investigative, and adjudicative workload without state reimbursement.
Key Issues
The Core Tension
The bill tries to harden the provenance and integrity of medical records by giving the authoring physician exclusive control over edits, but that protection conflicts with the operational reality of team-based care and EHR practices that rely on delegation, shared documentation, and retrospective corrections—creating a trade-off between record fidelity and clinical efficiency (and potentially imposing criminal risk on clinicians for routine documentation work).
The bill’s apparent clarity masks several implementation frictions. First, it does not define routine documentation practices such as “corrections,” ‘‘addenda,’’ or the acceptable process for retrospective amendments; enforcing a strict ban on edits without procedural detail will produce disputes about what counts as an impermissible alteration versus a permitted correction.
Second, the delegation exception hinges on a delegation ‘‘under the authority delegated by the authoring physician’’—the statute does not specify what form that authorization must take (verbal, written, templated EHR consent), so providers and institutions will need to create documentary standards to rely on the exception in enforcement or defense. Third, the bill criminalizes or treats as unprofessional certain documentation conduct without creating an administrative correction pathway; that raises due-process and proportionality questions in cases involving innocuous edits (formatting, typo fixes, auto-populated fields) that nevertheless fall within the statute’s literal prohibition.
Operationally, the law collides with modern team-based and EHR-dependent workflows: clinicians commonly use templates, shared note building, and scribe-assisted documentation to preserve throughput and accuracy, and the statute’s individual-liability framing may discourage efficient delegation or push institutions to centralize documentation controls. Finally, the fiscal clause disclaims state reimbursement by relying on the constitutional carve-out for criminal-law changes, but it does not offset the real administrative and technology costs local entities and health systems will incur to implement compliant workflows and defend against increased enforcement activity.
