How to Conduct a HIPAA Risk Assessment for AI Transcription Tools

Why AI transcription needs its own risk assessment

You probably already do an annual HIPAA risk assessment. Good. But that general assessment likely doesn't account for the specific threats that come with AI-powered transcription.

AI transcription introduces risks that traditional documentation methods don't have: ambient audio capture in clinical settings, real-time data processing through machine learning models, and automated PHI generation from unstructured conversations. The OCR expects covered entities to evaluate these risks before deployment, not after a breach forces the issue.

The HIPAA Security Rule (45 CFR 164.308(a)(1)(ii)(A)) requires an "accurate and thorough assessment of the potential risks and vulnerabilities to the confidentiality, integrity, and availability of electronic protected health information." An AI scribe creates, processes, and stores ePHI. It needs to be in your risk assessment.

Step one: map your data flows

Before you can assess risks, you need to know exactly where patient data travels. For AI transcription, the data flow typically looks like this:

1. Audio capture - Patient encounter recorded on a device (phone, tablet, desktop)
2. Transmission - Audio sent to the transcription service
3. Processing - AI model converts audio to text
4. Storage - Transcription saved in the vendor's systems
5. Retrieval - Provider accesses the note from their device
6. Integration - Note exported to the EHR
7. Retention/Deletion - Data kept per policy or destroyed

Document each step. For every step, identify what data exists, where it lives, who can access it, and how it's protected. This creates your data flow map - the foundation of the entire risk assessment.

Step two: identify threats and vulnerabilities

With your data flow mapped, examine each point for potential threats. Here are the most common ones specific to AI transcription:

Audio capture threats:

• Ambient recording captures conversations not related to the patient encounter (other patients, staff discussions)
• Device stolen or lost with cached audio data
• Unauthorized person activates recording

Transmission threats:

• Man-in-the-middle attacks intercepting audio data
• Audio transmitted over unsecured Wi-Fi networks
• Connection drops causing retransmission of unencrypted data

Processing threats:

• Vendor employees accessing raw audio or transcriptions
• AI model inference attacks that extract training data
• Third-party sub-processors handling PHI without proper safeguards

Storage threats:

• Database breach exposing stored transcriptions
• Inadequate backup encryption
• PHI leaking into log files, analytics, or error reports

Integration threats:

• Insecure API connections between the AI scribe and your EHR
• Credentials for EHR integration stored improperly
• Transcription data sitting in an unencrypted staging area during export

Step three: assess likelihood and impact

For each threat, evaluate two things on a scale of low, medium, or high:

Threat	Likelihood	Impact	Risk Level
Device theft with cached audio	Medium	High	High
Man-in-the-middle during transmission	Low	High	Medium
Vendor employee accesses raw data	Low	High	Medium
PHI in application logs	Medium	Medium	Medium
Ambient capture of non-patient data	High	Low	Medium
Database breach at vendor	Low	High	Medium
Insecure EHR integration	Medium	High	High

Risk level combines likelihood and impact. High likelihood plus high impact is a high risk. Low likelihood plus low impact is low risk. Everything else falls in the medium range.

Your specific assessment will vary based on your practice setup, the vendor you choose, and your existing security controls.

Step four: document existing controls and gaps

For every identified risk, document what controls already exist to mitigate it - and where there are gaps.

For example:

Risk: Device theft with cached audio data Existing controls: Full-disk encryption on practice devices, auto-lock after 2 minutes Gap: No mobile device management (MDM) for remote wipe capability Remediation: Implement MDM solution before deploying AI scribe on mobile devices

Risk: PHI appearing in vendor application logs Existing controls: BAA requires vendor to prevent PHI in logs Gap: No way to independently verify the vendor's log practices Remediation: Request evidence from vendor (sanitized log samples, SOC 2 report section on logging)

Work through every threat this way. Be honest about gaps. The point isn't to have a perfect score - it's to know where your weaknesses are and have a plan to address them.

Step five: create your remediation plan

Every gap needs a remediation plan with four elements:

• What needs to be fixed
• Who is responsible for fixing it
• When it will be completed
• How you will verify it's done

Prioritize by risk level. High risks get addressed before the AI tool goes live. Medium risks should have a remediation timeline of 30-90 days. Low risks can be folded into your regular security improvement cycle.

The completed risk assessment - including your data flow map, threat analysis, gap analysis, and remediation plan - becomes a living document. Update it whenever the vendor changes their infrastructure, you modify how you use the tool, or new threats emerge.

Keep it for at least six years. The OCR can request it during an investigation, and "we did one but can't find it" is the same as "we didn't do one" in their eyes.
