Health care can be defined as an information industry; most of the time and money spent in procuring and delivering health care is spent creating, retrieving, or using information. Expenditures on health care information technology support, for example, have increased from about one billion dollars in 1990 to a projected $20 billion in 2000. Yet, even with these investments, it is believed that almost half of all current health care expenditures continue to be for non-patient care activities; a major share of which is for non-automated information support.
Resources having to be directed to non-patient care activities have been endemic in the health care industry since the 1960's. During the 1990's, however, with the demise of Medicare Cost Reimbursement and the rise of managed care, there has been a major shift in attitude and focus among both physicians and patients. New rules now govern the delivery of medical care and the payment for such care. Whether via preferred provider arrangements, capitation arrangements of endless variety, case management, or “best practice” enforcement, determining what care is allowed, what will be paid by whom, and making sure that the appropriate information is submitted to ensure that the process works are now consuming a major share of both time and financial resources of insurers, providers, and patients.
Health care participants, like providers and employers, regularly deal with a number of health care plans from various health insurers. These participants, however, can only obtain information from the insurance companies in limited ways, often making the acquisition of such information quite burdensome. Participants usually only have the telephone, fax, or letter available as a means of communication with the insurers.
Particularly vexing is the timely availability of information from insurers regarding financial transactions, such as eligibility, claims, and benefits, and basic patient-related information, such as medical tests and prescriptions. For example, a provider may seek information from an insurer via a submission form or telephone call to that insurer. In many cases, however, such information is sought or received after the care has been delivered and the patient has left the provider's office. This may result in the delivery of services that are not authorized or covered by the patient's insurer, or may result in other consequences that might impact the type or cost of the services provided.
Another reason for these difficulties is the recent expansion of the “payor” community. At one time, payors consisted of the government (both federal and state) and large insurance companies. Now, a complex array of self-insured plans, IDN's, IPA's, and PPO's, undertaking full or partial capitation, insurance carve-outs, and the like have radically increased the number of users of, and the need for, current information regarding insureds. Most of these entities, both small and large, do spend considerable sums on information systems. Yet, because of the extent of manual processing that exists despite these systems, costs per claim remain substantial.
In addition, payors incur the wrath of their providers and patients by designing complex rules that are difficult or perceived as impossible to administer or follow. Though contrary to this perception, payors do have an interest in providing timely information to providers, patients, employers, and other participants. Still, a significant percentage of a provider's claims are rejected often because they do not comply with all of the rules. These claims require resubmission, telephone calls, and other expensive manual interventions. The dollar costs for this current processing scheme are high. In fact, an entire clearinghouse industry has been developed to provide eligibility (but not benefits) verification services to providers for a fee. Many of the requested verifications, however, cannot be performed at all by such clearinghouses, and those that are performed are often unacceptably cumbersome and, thus, too expensive.
Referral authorizations are often even more complex than claims and such authorization services are generally not available via traditional clearinghouses. Each time a provider writes a prescription, for example, it is written against a formulary specific to that patient's health care plan established by their insurer. Because there are so many formularies, drug prescriptions, too, are often rejected for payment, causing additional work for both the provider and the patient. Similarly, medical tests must be sent to laboratories contracted to support a particular plan, and are reimbursed only when matching complex medical necessity rules.
Many providers do have practice management systems that track encounters and manage billing. None of these systems, however, have the sophistication to accomplish the task of providing all of the information from all the various health insurers in such a cogent form that can be useful to the provider.
Not only providers, but patients, too, spend a majority of their time interacting with the health care system engaged in non-health care activities. This “wasted” time is virtually all related to scheduling appropriate interventions, to waiting for information or services, or to obtaining authorization, reimbursement, or other information for desired or required health care.
The internet has emerged as a major source of health care information for the public. A substantial portion of internet users use it for health care information or management. Specifically, patients search the internet for medical information and answers related to their area of concern. In fact, it is becoming common for a patient to enter a physician's office armed with printouts and long lists of questions and recommendations from web pages on the internet.
Unfortunately, even with the connectivity the internet provides, information exchange between insurers and patients is lacking. Most of the information available to patients from their insurer is on an automated basis from databases related to either general health care literature or to specific normality support groups. A critical aspect of the patient's health care program, however, is not only knowledge of the normality or support groups, but also what their insurer's health care plan provides as treatment options for that normality, eligibility information, referral authorization, claim submission and payment, testing, and medications. As discussed, these functionalities are too complicated for the current system to handle in an automated environment. Personally-referenced information linked to an individual patient's provider and health care plan is generally unavailable, because that data exists in several databases often each in a different, incompatible format, requiring human intervention to extract and process the data. The patient's current solution is, thus, an endless number of telephone calls at a high cost in dollars, time, and frustration.
A reason for such incompatibility is that each database served the individual needs of those using the data before such a time when connectivity between databases was a consideration. The consequence of having different databases of different formats is that it is not possible to provide a central repository of homogenized data readable by any variety of computers. It is this incompatibility that prevents wide spread connectivity between insurers and participants.
Transliterating and interfacing programs are known in the art. Programs that take data in one format can be translated and read by a computer of a different format. Such transliterating, however, only shifts data from a field of an incompatible format to a target field of a new format. It cannot determine whether the data of the incompatible format is being transferred to the correct target field. Normalization or remodeling of the data not only transfers the data, but also determines the meaning of the data and puts that data in the correct field.
It would, therefore, be beneficial to provide a system with which insurers may communicate with providers, patients, etc., to provide information about a particular health care plan either before, or contemporaneously with, the patient's visit to the provider, regardless the lack of compatibility of the databases. It would be further beneficial if this system of communication spanned a variety of insurers so the provider, for example, may communicate with any plan in which the patient participates. It would also be beneficial for providers to have an automated system of determining eligibility and benefits, receiving authorizations and pre-certifications, submitting claims, obtaining reimbursements, and adjudicating claim problems through the normalization of data of the incompatible databases.
Accordingly, an illustrative embodiment of the present disclosure provides an apparatus for communicating health care data from a sender to a receiver. The apparatus comprises a first computer system, a second computer system, and a rules engine. The first computer system having health care data stored therein.

When the receiver is a patient, the normalized data exchanged between the sender and receiver is chosen from a group comprising identification card requests, address changes, provider directory inquiries, personalized health information based on an interest profile, diagnosis information, relevant articles and patient education materials, communications from health care providers and health care plans, lab and radiology results, scheduled appointments with a health care provider, prescription refills, personal health records, eligibility/benefit information, claim 1nformation, referral and authorization information and status, provider lookup, family history, medication profile and formulary lookup.
Another illustrative embodiment of the present invention provides a system of normalizing health care data for transfer between an insurer and a participant. The system comprises an insurer system, an intermediary system, and a participant system. The insurer system is configured to maintain at least one database comprising the health care data. The intermediary system is operatively connected to the insurer system and to the database, configured to extract the health care data from the database of the insurer system, and store the health care data in a staging database as extracted data. The extracted data is normalized to a predefined format, creating normalized data pursuant to a rules engine that defines each field of the extracted data in the predefined format. The rules engine also defines how the normalized data relates to each other pursuant to predetermined instructions. The participant system is in operable communication with the intermediary system, and is configured to receive the normalized data subject to the rules engine.
Further embodiments of the illustrative system may include the at least one database being a plurality of databases, such that the intermediary system is operatively connected to the plurality of databases. In addition, the participant system may transmit a request that is sent to the intermediary system that determines which health care data is to be extracted and normalized in order to respond to the request. The participant system may also transmit the request, and the intermediary system may transmit the normalized data over the internet. The rules engine may define the relationships among the normalized data pursuant to predetermined instructions to determine a response to the request. The intermediary system may also comprise an error data system that removes extracted data identified as invalid when the extracted data is normalized. The extracted data identified as invalid is then corrected, reintroduced, and is normalized. The intermediary system may further comprise an audit database to track the activity of the intermediary system.
Another illustrative embodiment of the present invention provides a system of health care management of medical testing administration between an insurer, a medical laboratory, and at least one health care participant. The system comprises a participant computer, an insurer processing system, a rules database, and a laboratory computer. A medical test request is made at the participant computer pursuant to a first predetermined format. The insurer processing system is operatively coupled to the participant's computer, and is through which the medical request is transferred. The processing system is operatively coupled to the rules database to approve the medical test request pursuant to predetermined criteria. The laboratory computer is operatively coupled to the processing system and receives the medical test request if approved by the rules engine. Results of the medical test are transmitted from the laboratory computer to the processing system. The results are further transmitted to an insurer computer that is operatively coupled to the laboratory computer and to participant's computer.
Further embodiments of the illustrative system may include the processing system converting the results of the medical test to a second predetermined format readable by a database stored on the insurer computer. In addition, at least one health care participant may be chosen from a group comprising from a health care provider, an employer, and a patient.
