Executive summary. In May 2024, the U.S. Department of Health and Human Services’ Office for Civil Rights (HHS‑OCR) finalized rules under Section 1557 of the Affordable Care Act that make health‑care organizations legally responsible for managing discrimination risk from “patient care decision support tools,” including AI. The rule creates a reasonable‑efforts duty to (1) identify tools that use protected characteristics and (2) mitigate associated discrimination risks. Several states now also require a qualified clinician to review AI‑assisted prior‑authorization or claim denials, with more considering similar laws. These moves raise the bar for product design, procurement, and day‑to‑day operations across providers, payers, and health‑tech vendors. At the same time, new studies continue to show model bias—especially against women and ethnic minorities—pressuring technology firms to prove progress, not just promise it. The commercial upshot is clear: algorithmic fairness and human‑in‑the‑loop oversight have become business requirements—affecting P&L, go‑to‑market, liability exposure, and competitive differentiation.

1) The new federal baseline: “reasonable efforts” are now a legal duty (with real dates)
HHS‑OCR’s Section 1557 final rule prohibits discrimination through the use of patient‑care decision support tools. Covered entities must make reasonable efforts to identify tools that employ protected traits (race, color, national origin, sex, age, disability) and then make reasonable efforts to mitigate the discrimination risk from those tools. Compliance for these provisions was due within 300 days of the rule’s effective date (i.e., by roughly early May 2025). OCR has signaled a case‑by‑case, complaint‑driven enforcement posture. For business leaders, this converts “AI fairness” from an aspirational value into a regulated operational control that must be budgeted, documented, and auditable. Federal Register+2Federal Register+2
Business impact. Expect new line items for tool inventories, bias assessments, governance workflows, and ongoing monitoring. Procurement will have to verify developer disclosures; clinical leadership will need a documented method to evaluate risks and mitigations; compliance teams will track—and evidence—“reasonable efforts” calibrated to organizational size and resources. Federal Register
2) State laws are reshaping payer operations: clinician sign‑off before AI‑assisted denials
A growing bloc of states now require that an MD or qualified health‑care professional review any health‑insurance claim or prior‑authorization request before it can be denied; six states—Arizona, California, Indiana, Maryland, Nebraska, and North Dakota—have enacted variants of this requirement, and nearly two dozen more states introduced similar bills in 2025. For payers, that converts fully automated denial flows into assisted workflows with human review steps, documentation requirements, and specialty alignment. That adds staffing, training, and QA costs—and reduces throughput—but it also reduces exposure to “practicing medicine without a license” theories and to headline risk from algorithm‑only denials. Cooley+1
Business impact.
- Opex & SLAs. Denial decisions will take longer; expect to re‑baseline service levels and reconsider auto‑denial thresholds.
- Workforce design. Build capacity for physician/peer reviewers in relevant specialties; implement case routing rules that keep AI assistive but never dispositive.
- Controls & evidence. Log who reviewed what, when, and on what basis; maintain explainability artifacts for each decision; publish public‑facing notices where required. Cooley+1
3) Technology reputations are on the line: from promises to provable progress
Recent evaluations show that widely used models can downplay or underspecify symptoms for women and provide less supportive language for some racial and ethnic groups. In reporting on these studies, technology companies have acknowledged the problem space while emphasizing progress: OpenAI has noted that many studies test older GPT‑4 variants and says accuracy has improved; Google says it takes bias “extremely seriously” and is working on discrimination‑limiting techniques. This is moving buyer expectations toward evidence of improvement, not statements of intent. Vendors that ship “assurance packs” (model cards, subgroup performance, external audit summaries) will pick up market share. Financial Times+2Engadget+2
Business impact. Health‑tech sellers should expect RFPs to demand: subgroup accuracy tables; known‑issue registers; mitigation plans; and monitoring APIs. Buyers will favor models and tools with independent validation against realistic, demographically balanced test suites. Nature
4) Why this won’t blow over: the bias is in the data and the development pipeline
Researchers continue to warn that unless organizations change what data they use and how they build and deploy models, AI will mirror—and sometimes amplify—historical inequities in medicine. Foundational papers and 2025 reviews trace bias to skewed datasets, proxy variables (like “cost” standing in for “need”), and uneven performance on under‑represented subgroups. In imaging, for example, models can infer sensitive attributes (like race) from clinical images in ways humans cannot, making naïve “blindness” strategies ineffective. This is why regulators are telling users of AI to examine inputs, outcomes, and mitigations—not just vendors’ claims. Nature+2Harvard Medical School+2
Business impact. Treat data work as product work. Budget for dataset curation, targeted data collection for under‑represented cohorts, and post‑deployment drift and fairness monitoring. Prioritize interventions that change behavior (e.g., thresholding by subgroup, calibrated uncertainty prompting human review) over one‑time bias scans. Nature
5) Liability & enforcement: where new costs and risks will show up
- OCR investigations & private suits. OCR will investigate complaints and conduct compliance reviews; individuals can sue under Section 1557 (with some debate around disparate‑impact claims). Expect discovery demands for tool inventories, review procedures, and mitigation records. JAMA Network
- Payer litigation & AG attention. Allegations around automated denials are drawing plaintiffs, journalists, and lawmakers, reinforcing the economic case for clinician‑in‑the‑loop workflows and clear documentation. The Guardian+1
- Contractual risk transfer. Hospitals and plans will push more obligations upstream—to EHRs and AI vendors—via warranties, audit rights, and indemnities tied to discriminatory outputs or undisclosed use of protected attributes. Federal Register
6) What different players should do next (a pragmatic playbook)
For providers and integrated delivery networks
- Build the inventory. Catalogue every patient‑facing and clinician‑facing decision support tool; flag inputs that directly or indirectly measure protected traits; record intended use. Federal Register
- Stand up a 1557 review board. Establish a rapid review process that evaluates subgroup performance, proxy‑variable risk, and mitigation steps before go‑live; keep minutes and artifacts. Federal Register
- Operationalize mitigation. Options include clinician overrides on low‑confidence or high‑risk cohorts; subgroup‑specific thresholds; adverse‑impact testing akin to quality measures. Nature
- Document “reasonable efforts.” Use OCR’s factors (size/resources, use as intended, developer disclosures, evaluation methodology) as your checklist. Federal Register
For payers (health plans, TPAs, PBMs)
- Re‑engineer prior‑auth and denial flows. Insert specialty‑appropriate clinician review prior to denial; maintain auditable records of human rationale; publish process disclosures where required. Cooley
- Calibrate economics. Re‑baseline denial rates, appeal reversals, and cycle times under human‑review constraints; invest where savings offset regulatory and litigation risk. Manatt
- Communicate with regulators. Be ready to show how AI is used (assistance vs. decision), who reviews it, and what protections keep group data from driving individual denials. Manatt
For health‑tech and AI vendors
- Ship an “assurance package.” Include model cards, intended‑use boundaries, subgroup performance on clinically relevant test sets, known limitations, and post‑market monitoring plans. Nature
- Design for oversight. Build human‑review hooks, confidence scoring, and explainability suited to clinical workflows; log inputs/outputs for audit. Federal Register
- Tune on purpose, not just performance. Retrain with representative clinical data, remove harmful proxies, and validate mitigations prospectively—not just retrospectively. Nature
7) Procurement is changing: what buyers will now require (and sellers should prepare)
Expect contracts to add: (a) disclosure of protected‑trait use (direct or proxy); (b) fairness and performance warranties by subgroup; (c) right to audit training data lineage and evaluation methods; (d) incident reporting for suspected discriminatory outcomes; (e) indemnities for regulatory fines or civil claims tied to discriminatory tool behavior; and (f) termination rights for undisclosed changes to models that affect protected classes. These align with OCR’s emphasis on due diligence and with state laws’ insistence that AI cannot substitute for professional judgment. Federal Register+1
8) P&L outlook: costs, savings, and competitive advantage
- Costs rise before they fall. Near‑term costs include clinician review capacity, governance staffing, data curation, and external validation. But disciplined programs will reduce downstream costs—fewer escalations, appeals, and enforcement actions. Manatt
- Trust becomes a feature. Vendors that can prove low disparate impact and ship monitoring hooks will win institutional buyers; plans that advertise clinician‑review guarantees will face less churn and regulatory heat. Nature
- Avoidance beats remediation. Several studies suggest biases track back to historical data and proxies; investing in dataset redesign and life‑cycle mitigation is cheaper than defending lawsuits or rebuilding models under consent agreements. Nature+1
9) A 90‑day starter plan (usable by providers, payers, or vendors)
- Week 1–2: Name an executive owner; adopt the OCR §92.210 “reasonable efforts” factors as your control framework; freeze any new AI deployment until reviewed. Federal Register
- Week 3–6: Complete the tool inventory; run a rapid fairness scan on top‑volume tools; flag any direct/proxy protected‑trait inputs; implement interim guardrails (confidence thresholds → human review). Federal Register
- Week 7–10: Stand up a cross‑functional review board; convert interim guardrails into SOPs; embed logging for audits; renegotiate high‑risk vendor contracts with disclosure/audit terms. Federal Register
- Week 11–13: Publish internal guidance on when AI can assist vs. decide; rehearse an OCR inquiry; brief your board on risk posture and resourcing needs. JAMA Network
Bottom line
The policy signal is unmistakable: if you use AI in health care, you own the discrimination risk. The federal rule converts fairness into a documented compliance obligation; state laws are hard‑wiring human judgment back into denial decisions; and continuing research keeps the pressure on to fix data and development practices—not just PR. Organizations that treat this as a product and operations problem (not merely a legal one) will avoid penalties, reduce litigation exposure, and win trust in a market that is rapidly distinguishing between “AI‑enabled” and “assurance‑grade AI.” Federal Register+2Cooley+2
