Solution Overview

Problem

The current medical billing systems require physicians to manually enter complex service and diagnostic codes, consuming valuable time and increasing the risk of errors, which can lead to delayed or rejected claims and physician burnout.

Innovation Solution

A computer-implemented method and system that processes medical diagnostic information by identifying diagnostic terms within a text block, mapping these terms to corresponding service and diagnostic codes, and returning the matching codes, thereby automating the code identification process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If physicians manually enter service and diagnostic codes into claim forms, then billing accuracy can be maintained, but time consumption increases significantly and error risk rises

Engineering Contradiction:
Improvebilling accuracyVSAvoidtime consumption
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system enables self-service by automatically generating service and diagnostic codes through AI processing of clinical notes, eliminating the need for physicians to manually search and enter codes. The AI model autonomously extracts relevant information and maps it to appropriate billing codes, reducing time consumption while maintaining accuracy through automated validation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces the mechanical process of manual code entry with an automated AI-based system. The mechanical action of physicians typing and searching for codes is substituted by an electronic AI model that processes clinical text and generates codes automatically, significantly reducing time loss while maintaining billing accuracy through systematic processing.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If physicians spend more time on administrative billing tasks, then code accuracy may improve, but patient care time decreases

Engineering Contradiction:
Improvecode accuracyVSAvoidpatient care time
Core Design Contradiction:
Manufacturing precisionVSDuration of action of moving object

Solution Approach 1:

The billing system performs self-service by automatically generating accurate service and diagnostic codes without requiring physician intervention. This frees physicians from administrative tasks entirely, allowing them to dedicate more time to patient care while the AI system maintains code accuracy through its automated processing and validation mechanisms.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system performs preliminary action by generating billing codes automatically during or immediately after the patient encounter, before the physician would otherwise need to spend time on billing tasks. This preliminary automation ensures code accuracy is achieved without consuming physician time that could be spent on patient care.

Inventive Principle:
Principle #10Preliminary action

3Measurement precision

If complex rule-based code suggestions are provided, then billing precision may improve, but system complexity increases

Engineering Contradiction:
Improvebilling precisionVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent replaces complex mechanical rule-based systems with an AI-based semantic processing system. Instead of implementing numerous explicit billing rules and logic, the system uses natural language processing to understand clinical context and map it to appropriate codes, achieving billing precision while reducing system complexity by eliminating the need for explicit rule encoding.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the fundamental parameter of code generation from rule-based logic to AI-based semantic understanding. This parameter change allows the system to achieve billing precision through learned patterns and contextual understanding rather than explicit rules, thereby reducing system complexity while maintaining or improving billing accuracy.

Inventive Principle:
Principle #35Parameter changes

4Loss of time

If physicians receive no formal training on medical billing, then educational time is saved, but billing error rate increases

Engineering Contradiction:
Improveeducational timeVSAvoidbilling error rate
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The system performs self-service by automatically generating accurate billing codes without requiring physician knowledge or training in billing procedures. The AI model internally handles all billing logic and code selection, ensuring reliability and low error rates while eliminating the need for educational time investment in billing training.

Inventive Principle:
Principle #25Self-service

AI summary

Processing of medical diagnostic information returns comprises receiving a text block containing medical diagnostic information and returning corresponding tracking codes. Diagnostic terms may be identified within a text block containing medical diagnostic information, and the diagnostic terms may be mapped to corresponding respective tracking codes. At least one trained machine learning model, such as a large language model and/or a classifier, may be used to identify the tracking codes that correspond to the diagnostic terms.
