In the United States, a key distinction is between claim processing after care and prior authorization before care: federal rules address parts of the latter, while a separate CMS model is testing AI-supported reviews in a limited set of Original Medicare services.
What “AI in claims processing” can mean
Healthcare administration includes several different tasks that are often grouped together under “claims processing.” The distinction matters because a tool that checks a claim for missing information is not necessarily evaluating medical necessity, and a prior authorization decision is not the same as a post-service claim denial.

- Claim preparation: assembling codes and supporting records before a claim is submitted.
- Claim adjudication: a payer’s review of a submitted claim to determine how the plan’s coverage and payment rules apply.
- Prior authorization: a payer’s review of a requested medical item or service before it is provided.
- Documentation exchange: transmitting clinical records or other material needed to support a claim or review.
- Appeals: challenging a denial or other coverage decision through the applicable process.
AI could be used to support administrative work at different stages, but the sources available here do not establish a particular tool’s capabilities or results. They do not show that AI generally decides claim outcomes, prevents denials, or improves patient care.
What the 2024 CMS prior authorization rule changes
CMS’s Interoperability and Prior Authorization Final Rule, CMS-0057-F, applies to specified payer categories, including Medicare Advantage organizations, state Medicaid and CHIP fee-for-service programs, Medicaid and CHIP managed care entities, and Qualified Health Plan issuers on federally facilitated exchanges. Which requirement applies, and when, depends on the payer and provision. CMS says operational provisions generally begin January 1, 2026, while many API development and enhancement requirements generally begin January 1, 2027. CMS’s rule overview describes the scope and implementation dates.

Decision timeframes and denial reasons
For covered medical-item and service prior authorization requests under the rule, impacted payers generally must decide expedited requests within 72 hours and standard requests within seven calendar days. The standard-request timeframe has a stated exception for Qualified Health Plan issuers on federally facilitated exchanges. Beginning in 2026, covered impacted payers must provide a specific reason when they deny a covered prior authorization request. These are prior authorization requirements, not universal deadlines or explanation rules for every post-service claim denial. CMS excludes drug prior authorizations from these particular process provisions. See the CMS fact sheet for the rule’s details.
APIs support information exchange, not an AI verdict
The rule also requires certain FHIR-based APIs. The Prior Authorization API is intended to identify covered items and services and documentation requirements, and to support request-and-response workflows. An API can make information and process steps more accessible; its existence does not show that an AI system makes the coverage decision. CMS’s overview and fact sheet describe these requirements.
The rule does not establish an AI decision mandate
CMS stated in its final-rule response to comments that the rule does not directly address how prior authorization decisions are made, including whether they use AI, statistical methods, clinical decision requirements, or other algorithms, because those issues were outside the scope of that rulemaking. That statement describes the scope of CMS-0057-F; it is not an AI transparency or human-review mandate. The final rule text contains CMS’s response.
Where CMS is specifically testing AI-supported review
CMS’s Wasteful and Inappropriate Service Reduction (WISeR) Model tests enhanced technology, including AI, in selected Original Medicare prior authorization workflows. CMS says technology supports the review process, while licensed clinicians make final decisions that a request does not meet Medicare coverage requirements. The model is limited: it identifies selected services including skin and tissue substitutes, electrical nerve stimulator implants, and knee arthroscopy for knee osteoarthritis. It also excludes inpatient-only and emergency services, as well as services for which significant delay poses substantial patient risk. CMS’s WISeR announcement describes the model.
Rank #3
This is evidence of a bounded CMS test, not evidence that all Medicare or private-insurance claim denials are AI-generated. Nor does the announcement establish that the model improves accuracy, reduces inappropriate denials, speeds care, or saves money.
Claims attachments are a separate modernization effort
In March 2026, CMS finalized CMS-0053-F, adopting HIPAA standards for electronic health care claims attachments and electronic signatures. The standards address exchange of supporting material such as medical records, imaging, clinical notes, telemedicine documentation, and lab results. They concern the administrative transmission of records; they do not establish that AI reviews or approves those records. See the CMS-0053-F fact sheet.

CMS’s 2024 Medicare Advantage and Part D final rule includes utilization-management protections for Medicare Advantage plans. Among them, it limits coordinated-care-plan prior authorization policies to confirming diagnoses or medical criteria, or medical necessity; requires a minimum 90-day transition period for certain ongoing treatment when an enrollee changes plans; and requires utilization-management committees to review policies. These provisions apply in their specified Medicare Advantage context, not to all insurers, and they do not establish that AI is used or restricted. CMS explains them in its 2024 Medicare Advantage and Part D final-rule fact sheet.

How to assess an AI claim about denials
When a payer, vendor, or software provider says AI can reduce denials or make decisions smarter, ask what specific workflow and evidence the claim refers to. A useful assessment separates administrative assistance from coverage judgment and looks for results that can be checked.
- Identify the stage: Is the tool checking coding or completeness, assembling documentation, supporting prior authorization, adjudicating a submitted claim, or helping with an appeal?
- Clarify its authority: Does it flag an issue, recommend an action, or make a decision? Who can review or escalate the result?
- Check the explanation: Can the affected person see the denial reason, relevant coverage criteria, and information used to support the outcome?
- Understand the data path: What records can the system access, how does it connect to existing workflows, and can decisions and changes be audited?
- Demand comparable outcome evidence: A claim about accuracy, speed, savings, or overturned denials needs a dated measure with the population, payer, geography, period, and comparison baseline stated. The CMS sources described above do not provide such performance evidence.
For a person facing a denial, the practical next step is to use the denial notice and the plan’s applicable appeal or review process; a general claim that a payer uses AI does not explain a particular decision. The CMS rules discussed here concern specified prior authorization and administrative processes, and should not be treated as a substitute for the instructions and rights that apply to an individual coverage decision.
