## Content

Law firm analysis (Covington & Burling, leading healthcare regulatory firm) of FDA's January 6, 2026 revised CDS Guidance, which supersedes the 2022 CDS Guidance.

**Key regulatory change: enforcement discretion for single-recommendation CDS**
- FDA will now exercise enforcement discretion (i.e., will NOT regulate as a medical device) for CDS tools that provide a single output where "only one recommendation is clinically appropriate"
- This applies to AI including generative AI
- The provision is broad: covers the vast majority of AI-enabled clinical decision support tools operating in practice

**Critical ambiguity preserved deliberately:**
- FDA explicitly did NOT define how developers should evaluate when a single recommendation is "clinically appropriate"
- This is left entirely to developers — the entities with the most commercial interest in expanding enforcement discretion scope
- Covington notes: "leaving open questions as to the true scope of this enforcement discretion carve out"

**Automation bias: acknowledged, not addressed:**
- FDA explicitly noted concern about "how HCPs interpret CDS outputs" — the agency formally acknowledges automation bias is real
- FDA's solution: transparency about data inputs and underlying logic — requiring that HCPs be able to "independently review the basis of a recommendation and overcome the potential for automation bias"
- The key word: "overcome" — FDA treats automation bias as a behavioral problem solvable by transparent logic presentation, NOT as a cognitive architecture problem
- Research evidence (Sessions 7-9): physicians cannot "overcome" automation bias by seeing the logic — because automation bias is precisely the tendency to defer to AI output even when reasoning is visible and reviewable

**Exclusions from enforcement discretion:**
1. Time-sensitive risk predictions (e.g., CVD event in next 24 hours)
2. Clinical image analysis (e.g., PET scans)
3. Outputs relying on unverifiable data sources

**The excluded categories reveal what's included:** Everything not time-sensitive or image-based falls under enforcement discretion. This covers: OpenEvidence-style diagnostic reasoning, ambient AI scribes generating recommendations, clinical chatbots, drug dosing tools, discharge planning AI, differential diagnosis generators.

## Agent Notes

**Why this matters:** This is the authoritative legal-regulatory analysis of exactly what FDA did and didn't require in January 2026. The key finding: FDA created an enforcement discretion carveout for the most widely deployed category of clinical AI (CDS tools providing single recommendations) AND left "clinically appropriate" undefined. This is not regulatory simplification — it is regulatory abdication for the highest-volume AI deployment category.

**What surprised me:** The "clinically appropriate" ambiguity. FDA explicitly declined to define it. A developer building an ambient scribe that generates a medication recommendation must self-certify that the recommendation is "clinically appropriate" — with no external validation, no mandated bias testing, no post-market surveillance requirement. The developer is both the judge and the developer.

**What I expected but didn't find:** Any requirement for prospective safety monitoring, bias evaluation, or adverse event reporting specific to AI contributions. The guidance creates a path to deployment without creating a path to safety accountability.

**KB connections:**
- Belief 5 clinical AI safety risks — directly documents the regulatory gap
- Petrie-Flom EU AI Act analysis (already archived) — companion to this source (EU/US regulatory rollback in same 30-day window)
- ECRI 2026 hazards report (archived this session) — safety org flagging harm in same month FDA expanded enforcement discretion
- "healthcare AI regulation needs blank-sheet redesign because the FDA drug-and-device model built for static products cannot govern continuously learning software" (KB claim) — this guidance confirms the existing model is being used not redesigned
- Automation bias claim in KB — FDA's "transparency as solution" directly contradicts this claim's finding that physicians defer even with visible reasoning

**Extraction hints:**
1. "FDA's January 2026 CDS guidance expands enforcement discretion to cover AI tools providing 'single clinically appropriate recommendations' — the category that covers the vast majority of deployed clinical AI — while leaving 'clinically appropriate' undefined and requiring no bias evaluation or post-market surveillance"
2. "FDA explicitly acknowledged automation bias in clinical AI but treated it as a transparency problem (clinicians can see the logic) rather than a cognitive architecture problem — contradicting research evidence that automation bias operates independently of reasoning visibility"

**Context:** Covington & Burling is one of the two or three most influential healthcare regulatory law firms in the US. Their guidance analysis is what compliance teams at health systems and health AI companies use to understand actual regulatory requirements. This is not advocacy — it is the operational reading of what the guidance actually requires.

## Curator Notes

PRIMARY CONNECTION: Belief 5 clinical AI safety risks; "healthcare AI regulation needs blank-sheet redesign" (KB claim); EU AI Act rollback (companion)
WHY ARCHIVED: Best available technical analysis of what FDA's January 2026 guidance actually requires (and doesn't). The automation bias acknowledgment + transparency-as-solution mismatch is the key extractable insight.
EXTRACTION HINT: Two claims: (1) FDA enforcement discretion expansion scope claim; (2) "transparency as solution to automation bias" claim — extract as a challenge to existing automation bias KB claim.
