Prior authorization is an insurance review process used by healthcare providers to confirm medical coverage with health insurance companies.

This process involves submitting detailed documentation and clinical justifications to insurance companies, which puts significant strain on healthcare providers. This can result in care delays, negative clinical outcomes, and increased costs, with the administrative cost for physicians processing prior authorization requests amounting to $528 million in 2019.

In this post, we will outline how Neurons Lab, an AWS Advanced Tier Services Partner and AWS Marketplace Seller with Competencies in Machine Learning and Healthcare, collaborated with Treatline on its platform to streamline the highly manual prior authorization process using intelligent document processing (IDP) and generative AI.

Its innovative platform bridges the gap between healthcare providers and insurance companies, promoting greater efficiency and collaboration to ensure the best possible outcomes for all parties involved.

Challenge: Inefficiencies in Prior Authorization

Prior authorization is a pre-approval process required by insurance companies to confirm the medical necessity and coverage of specific treatments, procedures, medications, or services before they are performed or provided. It involves submitting detailed documentation and clinical justifications to the insurance company, demonstrating the need for the proposed healthcare intervention.

Prior authorization is often a time-consuming process that leads to staff burnout and negative impacts on patient care. Physicians spend an average of 14 hours per week on prior authorization tasks, submitting around 40 requests per week. Additionally, 90% of physicians describe the burden associated with prior authorization as high or extremely high.

Patients also suffer, with 93% of physicians reporting care delays, and 42% stating that prior authorization has led to serious adverse events for their patients, such as hospitalization, life-threatening events, or even death.

Insurance companies are affected by the inefficiencies in the prior authorization process as well. Delays in claim approvals and the complex, manual nature of the process contribute to increased operational costs and dissatisfied customers.

Despite 90-95% of prior authorization requests being approved eventually, the process involves time-consuming steps for both healthcare providers and insurance companies, including collecting data, submitting requests, and handling denials and appeals. These inefficiencies call for a streamlined solution that benefits all parties involved.

Solution: Automation and AI-Powered Platform

Treatline’s platform, developed in partnership with Neurons Lab, leverages cutting-edge AI technology and AWS services to streamline the prior authorization process for insurance companies and healthcare providers. The platform consists of three main components: web app, intelligent document processing (IDP), and the Generative AI Criteria Matching System.

Web App

The web app provides insurance and healthcare providers with a user-friendly interface, hosted on Amazon Simple Storage Service (Amazon S3) and served by Amazon CloudFront for fast and reliable access. User authentication is managed by Amazon Cognito, while the backend utilizes Amazon API Gateway, AWS Lambda, and Amazon DynamoDB for secure data storage and management.

Intelligent Document Processing

IDP is a key component of the Treatline platform, responsible for extracting, collecting, and interpreting data from medical records and documents, as well as insurance claim forms.

By utilizing advanced techniques, such as natural language processing (NLP), optical character recognition (OCR), and computer vision, IDP ensures accurate and efficient data processing for both insurance and healthcare professionals. This significantly reduces the time spent on administrative tasks, allowing them to focus on patient care and claim processing.

Advanced Text and Structural Data Extraction

IDP leverages Amazon Textract to extract both text and structural information from medical and insurance documents, such as tables and key-value pairs. This powerful OCR technology enables the platform to recognize and process complex documents with a high degree of accuracy, ensuring all relevant information is captured and utilized in the prior authorization process.

In-Depth Document Analysis

Once the text and structural data have been extracted, IDP utilizes Amazon Comprehend and Amazon Comprehend Medical to further analyze the content of medical and insurance documents. These AI-powered services identify critical information such as entities, medical terms, and relationships, allowing the platform to gain a deep understanding of each patient’s medical history, insurance coverage, and requirements.

Intelligent Search

To enable quick and efficient retrieval of the extracted information, IDP uses Amazon Kendra and Amazon CloudSearch to create smart search indexes. Amazon Kendra is a machine learning-based enterprise search service, while Amazon CloudSearch is a fully managed search service. Both services allow users to search and retrieve relevant medical and insurance data effortlessly, further enhancing the platform’s efficiency.

The extracted information is then indexed and stored in an Amazon S3 bucket, with metadata stored in a DynamoDB database. This enables efficient retrieval and analysis of the data when generating prior authorization requests and processing insurance claims.

Scalable and Efficient Document Processing

To handle high volumes of documents and ensure the platform remains responsive, IDP employs an asynchronous processing approach. This is managed through Amazon Simple Notification Service (Amazon SNS) and Amazon Simple Queue Service (Amazon SQS), which control the flow of documents awaiting processing.

This architecture ensures the platform can scale to meet the demands of healthcare and insurance providers, regardless of their size or the number of prior authorization requests and claims they submit.

Seamless Integration with Treatline Platform Components

IDP is fully integrated with the other components of the Treatline platform, such as the web app and the Generative AI Criteria Matching System. This seamless integration allows healthcare and insurance providers to benefit from the power of AI and advanced data processing techniques, streamlining the prior authorization process and improving efficiency across the board.

By combining the capabilities of IDP with the other components of the Treatline platform, healthcare and insurance providers can significantly reduce the time and effort required for prior authorization and claim processing, leading to better patient outcomes and more efficient healthcare and insurance delivery.

Enhanced Decision-Making with Generative AI

The Generative AI Criteria Matching System efficiently processes medical summaries and matches them with the appropriate criteria for specific procedures. Let’s consider an example.

Input Medical Summary: Patient is a 52-year-old female presenting with cervical radiculopathy and upper extremity weakness. The patient has a positive Hoffmann sign, disturbance with coordination, and no signs of hyperreflexia or positive Babinski sign/clonus. MRI results confirm cervical spondylosis causing spinal instability.

The patient has undergone seven weeks of conservative treatments, including a structured program of physical therapy, home exercise program prescribed by a physical therapist, and epidural steroid injections. The symptoms persist, and the patient’s quality of life is significantly impacted.
