DESCRIPTION OF THE PREFERRED EMBODIMENT

[0013] An Internet navigational system of the present invention is indicated generally in FIG. 1 by reference numeral 20. The Internet navigational system 20 comprises a server 22 for enabling an Internet user to retrieve information. The server 22 comprises a computer database and a retrieval system. The retrieval system is preferably a database search engine (e.g., Broadvision, Verity, etc.). The server 22 is shown as a conventional computer system, rather generically comprising a network coupling device 24 of a suitable type, such as a high-speed analog or digital modem, a central processing unit (CPU) 26, a display 28 and a keyboard 30 for operator interaction. It should be understood that various means for entering data and observations other than keyboards are known. Such devices may include light pens, pointing devices such as a computer mouse, touch screens, or even microphones or video cameras or any other data input device, all of which can be configured to serve a function equivalent to a keyboard for purposes of this invention. The server 22 may, itself, be a computer network instead of the simple system shown in FIG. 1. In particular, server 22 may comprise one or more separate web servers and/or separate databases with extensive RAM and disk memory storage, or their functional equivalents. Although not shown in FIG. 1, portions of such a server network may be physically separate from one another, and these portions may communicate with each other over the Internet or over a separate network.

[0014] The navigational system 20 further includes at least one user terminal 30 coupled to the Internet 32 (or any other suitable communication network). The server 22 is also coupled to the Internet 32. In a commercially successful system, it is anticipated that there would be large numbers of user terminals of various different types in communication with the server 22. As is conventional at present, the user terminal 30 is shown as a conventional personal computer system including a display 34, a keyboard 36, a mouse 38, a system unit 40, and a modem 42. Usually, the modem couples to the Internet 20 via a data line 19 such as a cable or telephone line. Alternatively, the user terminal communicates with the Internet via wireless communication.

[0015] The server 22 is preferably functionally coupled to the Internet 32 and thus to terminals 32 via one or more dedicated, high-speed lines 34. The requirements for server 22 and high-speed lines 34 are dictated at least in part by the expected volume of data to be exchanged with users at user terminals and by the number of such user terminals and users that are expected to access the server.

[0016] Stated generally, the computer database has content stored therein and the content has a plurality of components. In the preferred embodiment, the content comprises a plurality of names of health care providers, such as physicians, chiropractors, nurses, psychologists, optometrists, etc. Consistent with the terminology used herein, each name constitutes a component of the plurality of names. Preferably, at least one standardized code (and more preferably at least one ICD or CPT code) is associated with each name.

[0017] The term “CPT codes” stands for Physician's Current Procedural Terminology codes and comprises a listing of descriptive terms and identifying codes for reporting medical services and procedures performed by physicians. The purpose of the terminology is to provide a uniform language for accurately describing medical, surgical, and diagnostic services. It provides an effective means for reliable nationwide communication among physicians, patients, and third parties. CPT descriptive terms and identifying codes currently serve a wide variety of important functions in the field of medical nomenclature. This system of terminology is the most widely accepted nomenclature for the reporting of physician procedures and services under government and private health insurance programs. CPT is also useful for administrative management purposes such as claims processing and for the development of guidelines for medical education and research by providing a useful basis for local, regional and national utilization comparisons. CPT codes are updated on an annual basis through the combined efforts of many individuals and organizations and are published through many outlets, including most medical organizations, providers, and the U.S. and most other governments. Most CPT codes are 5 digit codes, which can be modified by a number of suffixes.

[0018] As used herein, “ICD codes” means International Classification of Diseases codes. In 1948, the World Health Organization (WHO) published a statistical listing for tracking both morbidity and mortality. This listing, the International Classification of Diseases (ICD) led to the current text in international use today, the ICD ninth edition (ICD-9). This version precisely delineates the clinical picture of each patient, providing exact information beyond that needed for statistical groupings. ICD-9 codes are comprised of letters and numbers ranging from one letter and two numbers (generic diagnosis such as breast cancer) to one letter followed by 5 or more numbers. The extra digits constrict the diagnosis to become more specific.

[0019] A typical physician uses several CPT and ICD codes in his/her practice to chart and identify diagnoses or treatments of patient conditions. The specific CPT and ICD codes used may vary widely from physician to physician, even as to physicians having the same specialty. A primary reason for this is that the types of patients a physician might see vary from doctor to doctor. As between two plastic surgeons for example, one might specialize in breast augmentation and the other might specialize in treatment of burn victims. The former will use ICD and CPT codes concerning breast augmentation and the later will use ICD and CPT codes concerning diagnosis and treatment of burn victims.

[0020] As contemplated by the present invention, the ICD and CPT codes may be used to enable Internet users to find physicians. Perhaps stated more accurately, the ICD and CPT codes may be used to enable physicians to be located by potential patients which the physicians desire to treat. Rather than being listed by a relatively broad specialty, use of the ICD and CPT codes enables a physician to be listed for search-engine purposes by ailment, condition, and treatment options. A physician can choose to have his/her name be retrievable by any search within his/her area of practice, or can choose to have his/her name be retrievable only by searches related to certain ailments, conditions, or treatment options within his/her specialty. In other words, if a physician wants to expand his/her patient base for all areas within his/her specialty, all ICD and CPT codes within those areas can be associated with the physician's name. If a physician wants to expand his/her patient base for only certain areas of his/her specialty, the ICD and CPT codes concerning such certain areas can be associated with the physician's name. A physician can choose to have certain ICD and CPT codes associated with his/her name and choose to have other ICD and CPT codes not associated with his/her name.

[0021] Once a determination is made as to which ICD and CPT codes to identify with a physician, the physicians name and selected codes are entered into the database of the server 22. The retrieval system communicates with the database and is adapted to retrieve some or all of the names of the health care providers associated with any one of the ICD or CPT codes upon receiving a signal sent by a user. The signal corresponds to any one of the ICD or CPT codes.

[0022] In the present embodiment, the server 22 comprises components of a host computer system, generally indicated at 50, and the signal sent by a user comprises a signal sent by a client computer system 52 communicating with the host computer system. The host computer system 50 communicates with the client computer system 52 in a manner for providing on the client computer system an interface for the host computer system, and the host computer system is adapted to receive the signal via the interface. The interface may comprise a box, icon, or button on a screen of the client computer system 52. For example, the interface might be a box prompting the user to directly input an ICD or CPT code (e.g., by typing the code directly in the box) to initiate a search. This input is received by the retrieval system of the server 22. Upon receipt, the retrieval system retrieves from the database the names of the health care providers (and/or other content) associated with the ICD or CPT code, and conveys the search results to the client computer system 52.

[0023] FIG. 2 shows an exemplary interface on a client screen, generally indicated at 60. Although the user may have the option of initiating a search by directly inputting an ICD or CPT code, it is expected that most Internet users will be unfamiliar with ICD and CPT codes. In one preferred mode of operation, the interface comprises a button or icon 62 appearing on the client screen 60 of the client computer system. Preferably, the icon 62 has a descriptive indicia (e.g., “Doctor Locator”) to indicate its purpose. Preferably, the icon 62 appears on the client screen when the user is accessing a particular community or micro-community (e.g., a web page, chat room, resource tool, drug database, etc.) containing information about or somehow related to a particular ailment, condition, or treatment option. The user may be directed to select the button or icon 62 in order to retrieve a relevant list of health care providers. Because the web page or chat room relates to a particular ailment, condition, or treatment option, the system is adapted so that selection of the button or icon by the user sends to the host computer system 50 a signal associated with the ICD or CPT codes related to such ailment, condition, or treatment option. Another type of possible community is a health map as disclosed in commonly owned and co-pending U.S. patent application Ser. No. 09/547,781, filed Apr. 12, 2000 and titled A NAVAGATION SYSTEM AND METHOD FOR USING THE SAME (incorporated herein by reference). The maps and map nodes connect to specific databases, one of which may be a listing of ICD and CPT codes which are then associated with healthcare provider names. Also, map nodes may point directly to a database of healthcare provider names who want to be associated with that map and map node. Commonly owned and co-pending U.S. patent application Ser. No. 09/425,779, filed Oct. 22, 1999, and titled APPARATUS AND METHOD FOR DIRECTING INTERNET USERS TO HEALTH CARE INFORMATION (hereby incorporated by reference) discloses use of ICD and CPT codes to obtain health care information. More particularly, such application envisions health care information being associated with ICD and CPT codes. The present invention complements the system described in such application by enabling a user to locate health care providers who specialize in the very subject matter that the user is then reading about.

[0024] In addition to providing the names of the health care providers associated with the ICD or CPT codes, it is to be understood that other information about the health care providers (e.g., the providers' addresses and/or telephone numbers, and perhaps some biographical information) may also typically be retrieved from the database and transmitted to the client computer system 52.

[0025] In practice, information about health care providers is stored in the database of the server 22. The information preferably includes basic information (e.g., name, address, telephone number) and specific information about the providers. The specific information includes the specific ICD and CPT codes with which any given provider wishes to be identified. Thus, Internet users retrieving health care information can also retrieve names and information of relevant health care providers.

[0026] In view of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

[0027] As various changes could be made in the above constructions and methods without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
