ABSTRACT:
MICROFICHE APPENDIX
This specification includes a Microfiche Appendix which includes 1 page of microfiche with a total of 37 frames. The microfiche appendix includes computer source code of one preferred embodiment of the invention. In other embodiments of the invention, the inventive concept may be implemented in other computer code, in computer hardware, in other circuitry, in a combination of these, or otherwise. The Microfiche Appendix is hereby incorporated by reference in its entirety and is considered to be a part of the disclosure of this specification.
I. BACKGROUND OF INVENTION
A. Field of the Invention
The invention relates to methods and systems for analyzing medical claims histories and billing patterns to statistically establish treatment utilization patterns for various medical services. Data is validated using statistical and clinically derived methods. Based on historical treatment patterns and a fee schedule, an accurate model of the cost of a specific medical episode can be created. Various treatment patterns for a particular diagnosis can be compared by treatment cost and patient outcome to determine the most effective treatment approach. It is also possible to identify those medical providers who provide treatment that does not fall within the statistically established treatment patterns or profiles.
B. The Background Art
It is desirable to compare claims for reimbursement for medical services against a treatment pattern developed from a large body of accurate medical provider billing history information. Although in the prior art some attempt was made to compare claims for reimbursement for medical services to a normative index, the prior art did not construct the normative index based on actual clinical data. Rather, the prior art based the normative index on a subjective conception (such as the medical consensus of a specialty group) of what the proper or typical course of treatment should be for a given diagnosis. Such prior art normative indices tended to vary from the reality of medical practice. In the prior art, automated medical claims processing systems, systems for detecting submission of a fraudulent medical claims, and systems for providing a medical baseline for the evaluation of ambulatory medical services were known. Documents which may be relevant to the background of the invention, including documents pertaining to medical reimbursement systems, mechanisms for detecting fraudulent medical claims, and related analytical and processing methods, were known. Examples include: U.S. Pat. No. 4,858,121, entitled “Medical Payment System” and issued in the name Barber et al. on Aug. 15, 1989; U.S. Pat. No. 5,253,164, entitled “System and Method for Detecting Fraudulent Medical Claims Via Examination of Service Codes” and issued in the name of Holloway et al. on Oct. 12, 1993; U.S. Pat.

No. 5,658,370, entitled “Knowledge Engineering Tool” and issued in the name of Erman et al. on Apr. 14, 1987; U.S. Pat. No. 4,667,292, entitled “Medical Reimbursement Computer System” and issued in the name of Mohlenbrock et al. on May 19, 1987; U.S. Pat. No. 4,858,121, entitled “Medical Payment System” and issued in the name of Barber et al. on Aug. 15, 1989; and U.S. Pat. No. 4,987,538, entitled “Automated Processing of Provider Billings” and issued in the name of Johnson et al. on Jan. 22, 1991, each of which is hereby incorporated by reference in its entirety for the material disclosed therein.
