Medical billing system and method
First Claim
1. A medical billing system comprising:
- a device for capturing data from patient encounter notes or similar information generated by physicians or care givers;
a first database comprising keywords;
a lexical engine for capturing keywords from the data while preserving a relative order or position of the keywords resulting in an output comprising a series of keywords in relative order or position;
a second database comprising keywords in relative order or position based on accurate bills from past encounters or from a predetermined list of accurate bills;
a statistical engine for comparing the output from the lexical engine with the second database and to produce a resulting bill with a confidence level prediction.

Abstract
A probabilistic medical billing system and method using contextual data and inferential logic for use in screening accuracy of medical bill coding and for presenting results as probabilities or predictions of correctness. The probabilistic medical billing system and method is accomplished using the contextual information contained in a care givers'"'"' patient encounter notes, a set of rules and keywords, and an inferential, logic, engine based on Bayesian mathematics or similar disciplines. The inventive device includes an input device to capture care giver'"'"'s encounter notes or other information, a lexical engine that extracts information while preserving the contextual order of the information, a relational database that contains keywords, phrases and rules and a statistical/probabilistic engine that uses Bayesian mathematics or similar disciplines to create the output. The lexical engine parses a document into words and is capable of extracting keywords or phrases as listed or defined in a master list. Further, the lexical engine would preserve the relative position of discovered keywords or phrases as the keywords or phrases and relative positions were encountered. The Bayesian engine is a mathematical algorithm that uses inferential logic to analyze historical data and shows the results as a predictive level as to the accuracy of a medical bill produced from the source documents. The inherent nature of Bayes like algorithms allows them to learn and improve their predictive capability through the use of a feedback system which is also part of the invention. Variations in algorithms and data flow can be easily made to support other predictive output related to billing or for the purposes of data mining and statistical evaluation.

20. A medical billing system comprising:
-
a database comprising accurately coded medical bills, wherein each of the bills has a set of keywords, phrases and related terms of interest in relative order, a first data analysis system for extraction of keywords, phrases and related terms of interest from inputted medical billing information and for providing output in the form of a stream of extracted keywords, phrases and related terms of interest in relative order; and
a second data analysis system for statistical comparison of the output of the first data analysis system to the database resulting in a probability that the inputted medical billing information is correct.
