Institution-Trained Generative AI for Prior-Authorization Letters

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The prior-authorization process is unforgiving, time-consuming, and varies significantly between institutions, leading to delays and substandard care due to medical professionals' inability to understand nuanced requirements, resulting in rejected letters and emergency room visits.

Innovation Solution

Generative language models are trained on prior-authorization documentation specific to a target institution, allowing medical professionals to quickly generate compliant letters through a user interface, with features like anonymization and format transformation to reduce exposure of personal information and network traffic.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If medical professionals manually prepare prior-authorization letters, then they can submit treatment requests, but the process is time-consuming and leads to delays in patient care

Engineering Contradiction:

Improveprior-authorization document generation speedVSAvoidpatient care delay

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system enables prior-authorization letters to be generated automatically through AI technology without requiring manual preparation by medical professionals. The AI model retrieves patient information, formats it according to institutional requirements, and produces compliant documents autonomously, transforming a manual service into an automated self-service process that dramatically reduces generation time and eliminates delays in patient care.

Inventive Principle:

Principle #25Self-service

2Reliability

If medical professionals prepare prior-authorization letters manually, then they can address institutional requirements, but they cannot understand nuanced requirements leading to rejected letters

Engineering Contradiction:

Improveprior-authorization approval rateVSAvoidunderstanding institutional requirements

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The AI model serves as an intermediary between medical professionals and institutional requirements. It translates complex, nuanced institutional criteria into automated formatting and content generation rules, acting as a mediator that bridges the gap between medical practitioners' knowledge and the specific requirements of each institution, thereby ensuring compliance and reducing rejections.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system performs preliminary actions by pre-loading and understanding multiple institutional requirement sets before document generation. The AI model is trained on and familiarizes itself with the nuanced requirements of various institutions in advance, so when a document needs to be generated, it already has the knowledge structure ready to comply with specific institutional criteria without requiring the medical professional to understand these nuances.

Inventive Principle:

Principle #10Preliminary action

3Device complexity

If prior-authorization letters are generated without AI assistance, then medical professionals maintain control over the process, but the complexity and time required increase significantly

Engineering Contradiction:

Improvedocument generation process complexityVSAvoidletter preparation time

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The system replaces the mechanical manual process of document preparation with an automated AI-based system. Instead of medical professionals manually gathering information, formatting documents, and ensuring compliance, the AI model performs these mechanical tasks automatically, substituting human manual labor with intelligent automation that reduces both complexity and time requirements while maintaining document quality.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Manufacturing precision

If personal information is included in prior-authorization documents, then the documents are complete and accurate, but data security and network traffic exposure increase

Engineering Contradiction:

Improvedocument completenessVSAvoiddata security risk

Core Design Contradiction:

Manufacturing precisionVSObject-affected harmful factors

Solution Approach 1:

The system segments the document generation process into separate functional modules: one that retrieves and processes personal information, another that formats the document, and a final review stage. This segmentation allows personal information to be handled in isolated, secure segments rather than exposed throughout the entire document lifecycle, reducing security risks while maintaining document completeness through controlled information flow between segments.

Inventive Principle:

Principle #1Segmentation

AI summary

In some implementations, the device may include receiving a prompt via a graphical user interface of a computing device, where the prompt identifies a target institution of a plurality of institutions, a patient condition, and a treatment. In addition, the device may include providing the prompt as input to ac generative language model, where the generative language model may include a pre-trained machine learning model that was initially trained on a general domain and subsequently trained on a target domain. The device may include receiving a generated pre-authorization letter as output from the generative language model, where the generated pre-authorization letter includes one or more fields identifying information requested from a user of the computing device. Moreover, the device may include presenting the generated pre-authorization letter to the user via the graphical user interface of the computing device.
