AB 1637 California Assembly · 2025-2026 Regular Session

Physicians and surgeons: medical records.

Summary
Existing law, the Medical Practice Act, establishes the Medical Board of California to license and regulate the practice of medicine. A violation of the act is a crime, unless otherwise specified. Existing law makes it unprofessional conduct for a failure of a physician and surgeon to maintain adequate and accurate records relating to the provision of services to their patients for at least 7 years after the last date of service to a patient. This bill would state that a physician and surgeon's patient notes, as defined, shall be the responsibility of that physician and surgeon. The bill would prohibit a physician and surgeon's patient notes from being altered, modified, or edited in any fashion by anyone other than the authoring physician and surgeon, except as specified. By expanding the scope of a crime under the act, the bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.

MINOR
The diff reflects a change from the formal enrolled bill document (with chapter heading, clerk signatures, and page numbers) to a web page rendering of the same bill on the California Legislature website. The substantive legislative text is identical in both versions; all changes are presentational, adding website navigation elements, metadata, and status information while removing formal enrollment formatting.
TECHNICAL

The document changed from a formal enrolled bill format (with chapter heading, Chief Clerk and Secretary of the Senate signature blocks, Governor's receipt line, and page numbers) to a web page layout including site navigation, search tools, bill status timeline, and metadata fields.
