An assistant that touches the medical record

A multi-site clinic’s assistant drafts visit notes, handles refill requests, answers portal messages, and assembles prior authorization packets. A check outside the assistant sends drafted notes to the treating clinician for signature, holds changes to treatment for a named, licensed person, refers disclosures outside treatment, payment, and health care operations to the privacy office, and lets routine tasks such as scheduling through.

Illustrative case. The clinic is fictional and the page is not clinical guidance, but the federal and state rules cited are real. Bracketed values are settings each organization chooses with its clinical and compliance leads.

The job

The assistant listens to visits (with consent) and drafts notes, triages refill requests, answers portal messages, sends records, and prepares prior authorization packets for payers. It reduces clinicians’ workload, but its possible failures include invented text in a note, a refill that should not happen, advice given without a clinician, and patient information sent to the wrong person.

What the assistant may do

In the assistant’s register of actions (P9), rules that come from law are marked with their source.

Four example requests

Rescheduling

Patient
“Can I move Tuesday’s appointment to later in the week?”
Assistant proposes
Move the visit to Thursday at 2:30 p.m. with the same clinician.
Layer checks
Scheduling within open slots is permitted. The message contains no clinical content.
Outcome
Rescheduled and confirmed to the patient in seconds.
action
appointment.reschedule Tue → Thu 14:30
policy
patient-access v4, rule 1.1
decision

A refill the law does not allow

Patient
“Please refill my oxycodone.”
Assistant proposes
Refill oxycodone 5 mg from the last prescription.
Layer checks
Oxycodone is a Schedule II controlled substance. Federal rules prohibit refilling a Schedule II prescription (21 CFR 1306.12(a)).
Outcome
Denied. The request goes to the prescriber’s queue for evaluation, and the patient is told that the prescriber will review it.

A drafted note enters the chart

Trigger
A visit ends, and the assistant has drafted the note from the recording.
Assistant proposes
Append the note to the signed medical record.
Layer checks
Entries in the legal record require the treating clinician’s attestation. The source audio must be retained until the note is signed and for [retention period] after.
Outcome
Held for the clinician, who reviews the draft with three low-confidence passages highlighted, corrects one, and signs.

A records request from an employer

Request
An employer’s HR office asks for a patient’s recent visit summary.
Assistant proposes
Send the visit summary to the employer.
Layer checks
A disclosure to an employer for its own purposes is not for treatment, payment, or health care operations, so it requires the patient’s valid authorization under the HIPAA Privacy Rule (45 CFR 164.508), and none is on file.
Outcome
Denied. The privacy office receives the record, and the requester gets the clinic’s standard authorization form.

Coverage decisions by health plans

The same pattern governs coverage decisions, and the law increasingly requires it. CMS told Medicare Advantage plans in February 2024 that an algorithm may assist a coverage determination but may not decide it from a larger data set in place of the individual patient’s medical history, the physician’s recommendations, or clinical notes. Nor may an algorithm alone end post-acute care or deny an admission. California’s SB 1120, in effect since 1 January 2025, requires that only a licensed physician or licensed health care professional deny, delay, or modify care based on medical necessity. Texas, Maryland, Arizona, Washington, and Iowa have since passed rules along similar lines. CMS’s WISeR model, which adds prior authorization for selected services in traditional Medicare in six states from 2026, says that all recommendations for non-payment are determined by appropriately licensed clinicians.

The layer treats a denial that a model recommends as a proposal. It holds the denial for a licensed reviewer, with the patient’s own record attached as evidence, and never permits it automatically.

Rule
rule:       adverse-determination
applies to: coverage.deny, coverage.reduce, coverage.delay
when:       basis includes medical necessity
decide:     hold for licensed physician or licensed health care professional
evidence:   the member's own history, physician recommendation, clinical notes
never:      permit without a named reviewer's decision

What the controls provide

Time saved for clinicians
The assistant handles drafts, scheduling, and routine requests, and clinicians review the decisions that need them.
Care decisions stay with licensed staff
Anything that changes treatment or the signed medical record waits for a named, licensed person, and disclosures outside treatment, payment, and health care operations go to the privacy office.
Records for compliance review
Compliance can show who signed what, what evidence they had, and which rule applied.

Review of drafted notes. People who approve many machine drafts tend to over-rely on them, which the EU AI Act calls automation bias. Clinics should highlight low-confidence passages, audit a sample of signed notes against the audio, and track how often drafts are signed unchanged.
