How a $1B+ healthcare services company achieved 192% ROI by automating healthcare disputes
Miss an arbitration deadline under the No Surprises Act and the reimbursement is gone. For a $1B+ healthcare services company processing 320,000 dispute emails a month through a single employee, that wasn’t a theoretical risk. phData built a platform powered by Anthropic Claude on Snowflake Cortex to automate healthcare disputes at scale, delivering 192% ROI.

The problem
The No Surprises Act established a federal arbitration process for out-of-network billing disputes, with strict deadlines providers must meet or forfeit the reimbursement. For a company fielding 320,000 dispute emails a month in formats that varied by payer, type, and urgency, no rules-based system could keep pace. Classification required a model that could read unstructured text at volume, and that’s where Anthropic Claude came in.
With $290M in receivables tied to the dispute pipeline and a single onshore employee managing the process alongside 100 offshore staff, every missed deadline had a measurable cost. When that employee left, the organization had no backup, no visibility into what was at risk, and no scalable path forward.
The No Surprises Act (NSA) is a federal law that limits out-of-pocket costs for patients receiving out-of-network care and establishes a strict independent dispute resolution process for providers and payers to resolve payment disagreements within defined deadlines.
Snowflake Cortex is a suite of AI and ML capabilities built directly into the Snowflake Data Cloud, allowing organizations to run large language models and AI functions on their existing data without moving it to a separate system.
Snowflake Cortex AISQL Functions are SQL-native AI capabilities within Snowflake that allow organizations to classify, extract, and analyze unstructured text data using large language models directly inside their Snowflake environment.
What phData did
Four decisions shaped the delivery.
phData transformed unstructured emails into a structured system of record
The legacy approach was email-centric: operations, finance, and legal managed disputes through overloaded inboxes. phData reimagined the process model before writing a line of code. In the new architecture, emails are an input and disputes are the unit of work, with AI pipelines classifying inbound emails and populating prioritized work queues automatically.
phData built natively on Snowflake using Cortex
phData used Snowflake Cortex AISQL Functions for email classification and Cortex Search for querying unstructured content, all within the client’s existing Snowflake environment. This eliminated data movement, kept the solution inside existing governance and security controls, and avoided introducing a new platform dependency.
phData used Anthropic's Claude (via Snowflake Cortex) for classification at scale
Payer dispute emails vary widely in format, language, and structure. A rules-based system would require constant maintenance as patterns changed. Claude efficiently handles shifting data formats via prompt-defined business objectives, classifying email intent and extracting required data elements at scale without ongoing rules management.
phData delivered a prioritized work queue application and real-time dashboards
The application surfaces the highest-risk disputes first, ranked by deadline proximity and dollar value. A centralized document repository automates access to negotiation materials, and near real-time dashboards give leadership visibility into aged accounts and win/loss rates.
The results
The $1.4M phase one investment generated $4.1M in total savings, delivering 192% ROI. Default losses and administrative fees dropped 50%. The full 320,000-email monthly volume is now processed automatically with 90%+ classification accuracy across all payer formats, a workload that previously required one onshore employee supported by 100 offshore staff.
The single point of failure is gone. The CFO and executive team specifically highlighted the platform’s value during year-end reconciliation. The architecture now establishes a foundation for agentic AI to automate arbitration artifact assembly, moving the platform from operational automation to active revenue recovery.

Why this matters beyond this project
The No Surprises Act applies to every out-of-network provider group and health system in the United States, and the core challenge is consistent: high volumes of unstructured payer communications that manual or rules-based processes can’t handle at scale. The architecture phData built here is repeatable: Snowflake Cortex as the AI and data layer, Anthropic’s Claude for classification, disputes as the unit of work rather than emails. Provider groups, health systems, and staffing organizations investing in No Surprises Act automation can follow the same pattern to protect AR, eliminate single points of failure, and build toward active revenue recovery.
Frequently asked questions
How does AI automate healthcare disputes?
Healthcare AI automation processes, classifies, and routes dispute communications between providers and payers, replacing manual email triage with intelligent, prioritized workflows. In practice, dispute emails are ingested, classified by type and urgency, and routed to the appropriate work queue without human review at the classification stage. The result is faster response times, fewer missed arbitration deadlines, and a process that scales without depending on individual staff capacity.
How does AI classify healthcare payer dispute emails at scale?
AI classifies healthcare payer dispute emails by using large language models (LLMs) to read unstructured email content, identify dispute type, extract required data fields, and route cases to the correct workflow without manual review. Unlike rules-based systems, LLMs like Anthropic’s Claude handle variation in payer email formats natively, eliminating the need for constant rules maintenance. Built on Snowflake Cortex, classification runs directly on existing data with no additional infrastructure required.
What is the No Surprises Act and how does it create financial risk for providers?
The No Surprises Act is a federal law that limits patient out-of-pocket costs for out-of-network care and establishes a strict independent dispute resolution (IDR) process for payment disagreements between providers and payers. Providers face financial risk because missed arbitration deadlines result in forfeited reimbursements. Every 2% of unresolved disputes can represent millions of dollars in lost revenue for large provider organizations, making automated triage a financial necessity.
What technologies does phData use for healthcare disputes?
phData uses Snowflake Cortex as the AI and data platform for healthcare dispute automation, with AISQL Functions handling email classification and Cortex Search enabling querying of unstructured content. Anthropic’s Claude runs natively through Snowflake Cortex for email reasoning and classification. All processing stays within the client’s existing Snowflake environment, with no separate AI infrastructure required.
What ROI can healthcare organizations expect from automating payer dispute workflows?
Healthcare organizations automating payer dispute workflows can achieve significant ROI: phData delivered 192% ROI in Phase 1 for a $1B+ healthcare services company, converting a $1.4M investment into $4.1M in total savings. The ROI comes from three sources: reducing default losses and administrative fees (50% reduction in this case), eliminating manual processing costs at scale, and preventing missed arbitration deadlines that result in forfeited revenue. Results scale with dispute volume and process maturity.
