International Classification of Primary Care

2011-07-12T17:25:15Z

The International Classification of Primary Care (ICPC-2) is a classification designed for primary care, developed by the World Organisation of Family Doctors (Wonca). It classifies information relating to why the patient has come for the consultation (the reasons for encounter), the problems managed during the encounter, procedures, referrals, imaging and pathology tests.

ICPC-2 classifies patient data and clinical activity in the domains of General/Family Practice and primary care, taking into account the frequency distribution of problems seen in these domains. It allows classification of the patient’s reason for encounter (RFE), the problems/diagnosis managed, interventions, and the ordering of these data in an episode of care structure.

List of Australian Refined Diagnosis Related Groups Version 5.1

2008-05-12T21:36:36Z

AR-DRG version 5.1 was released in October 2004. It is a minor update to the classification and incorporates ICD-10-AM Fourth Edition codes. The ADRG and DRG structure is unchanged from version 5.0.The latest available morbidity and patient-level cost data were used to test recommendations for the development of AR-DRG Version 5.1.
All recommendations were initially tested using morbidity and patient level cost data collected for the 2000/01 financial year. Morbidity data for financial years 2001/02 and 2002/03 morbidity data later became available, and some recommendations were tested using these data.
Data for the financial years 2000/01 and 2001/02, which were coded using ICD-10-AM Second Edition codes, were mapped to ICD-10-AM Third Edition codes and grouped to AR-DRG Version 5.0 to test recommendations for the development of Version 5.1. Data for financial year 2002/03 were coded using the ICD-10-AM Third Edition codes and grouped to AR-DRG Version 5.0 without mapping.
When AR-DRG Version 5.1 was finalised, it was tested using data which was forward mapped to ICD-10-AM Fourth Edition codes.

AR-DRG

2008-05-12T16:58:47Z

Australian Refined Diagnosis Related Group Classification System (AR-DRG). AR-DRG is a patient classification scheme based on ICD-10-AM codes. It provides a way of grouping the patients treated in a hospital according to clinical characteristics and resource use. AR-DRG definitions manuals are published by the Commonwealth Department of Health and Ageing and distributed by the NCCH.
Development of the AR-DRG classification is on-going. Currently, a new version is released every two years. It has been developed to classify acute admitted patient episodes in public and private hospitals. It has been produced by the Australian Government Department of Health & Ageing (DoHA), in consultation with the Clinical Casemix Committee of Australia (CCCA), Clinical Classification and Coding Groups, the National Centre for Classification in Health, State and Territory health authorities, and other organisations.

GALEN

2007-07-02T08:47:57Z

The GALEN CORE Model for representation of the Common Reference Model for Procedures contains the building blocks for defining procedures - the anatomy, surgical deeds, diseases, and their modifiers used in the definitions of surgical procedures. The GALEN Common Reference Model is the model of medical concepts (or clinical terminology) being built in GRAIL. This model forms the underlying structural foundation for the services provided by a GALEN Terminology Server.

National Drug Code (NDC)

2007-07-02T08:35:48Z

Drug products are identified and reported using a unique, three-segment number, called the National Drug Code (NDC), which is a universal product identifier for human drugs. FDA inputs the full NDC number and the information submitted as part of the listing process into a database known as the Drug Registration and Listing System (DRLS).

The International Classification of Diseases

2007-07-02T07:48:17Z

The International Classification of Diseases (most commonly known by the abbreviation ICD) provides codes to classify diseases and a wide variety of signs, symptoms, abnormal findings, complaints, social circumstances and external causes of injury or disease. Every health condition can be assigned to a unique category and given a code, up to six characters long. Such categories can include a set of similar diseases.

Diagnosis-Related Group (DRG)

2007-07-02T07:19:48Z

Diagnosis-Related Group (DRG) is a system to classify hospital cases into one of approximately 500 groups, also referred to as DRGs, expected to have similar hospital resource use, developed for Medicare as part of the prospective payment system. DRGs are assigned by a "grouper" program based on ICD diagnoses, procedures, age, sex, and the presence of complications or comorbidities. DRGs have been used since 1983 to determine how much Medicare pays the hospital, since patients within each category are similar clinically and are expected to use the same level of hospital resources. DRGs may be further grouped into Major Diagnostic Categories (MDCs).

HCFA Common Procedure Coding System (HCPCS)

2007-07-02T07:04:13Z

HCPCS (pronounced "hick-picks") is the acronym for the HCFA Common Procedure Coding System. This coding system provides a uniform method for healthcare providers and medical suppliers to report and bill for professional services, such as medical supplies, DME and transportation services (including ambulance services). Originally developed for use in billing the Medicare and Medicaid systems, it is now also recognized and used by other claim payors, educational and research groups, and utilization review organizations.

Current Procedural Terminology (CPT®)

2007-07-02T06:40:12Z

Current Procedural Terminology (CPT®) is a listing of descriptive terms and identifying codes for reporting medical services and procedures. The purpose of CPT is to provide a uniform language that accurately describes medical, surgical, and diagnostic services, and thereby serves as an effective means for reliable nationwide communication among physicians, and other healthcare providers, patients, and third parties. CPT was developed by the American Medical Association (AMA) in 1966.

Logical Observation Identifiers Names and Codes (LOINC®)

The purpose of the LOINC® database is to facilitate the exchange and pooling of results, such as blood hemoglobin, serum potassium, or vital signs, for clinical care, outcomes management, and research.
