Coding System

THO: The 'zzz' may be any printable ASCII string of variable length, but the recommendation is to generally use only numbers and uppercase letters, as that is how all of the currently existent table 396 entries have been created for many years. In addition, there is no explicit length restriction, but it is recommended that the string be kept below a 20 character maximum.

THO: Each code in this system represents a single line in a database template for the College of American Pathologists Electronic Cancer Checklist (CAP eCC). Each line and its code corresponds to either a question or an answer selection. The code is in a decimal format of #########.#########, where each "#" is an optional number. The nine digits to the right of the Ckey decimal point make up a namespace identifier, which is specific to the center that created the database entries for the checklist line items with their unique Ckey values. The namespace identifier for SNOMED Terminology Solutions at the College of American Pathologists is 1000043. All Ckey values in the 2008 release use namespace 1000043. The digits to the left of the decimal point are a locally assigned sequential key for the ChecklistTemplateItems table in the local CAP eCC database. These codes are used to specify questions and answers selected in a CAP eCC template for transmission in an HL7 message, as defined by the NAACCR Pathology Workgroup and the CDC/NPCR Reporting Pathology Protocols II (RPP II) project.

The concepts in this coding system will be mapped to SDO Vocabulary when it is available.

THO: The U.S. Centers for Disease Control and Prevention (CDC) has prepared a code set for use in coding race and ethnicity data. This code set is based on current federal standards for classifying data on race and ethnicity, specifically the minimum race and ethnicity categories defined by the U.S. Office of Management and Budget (OMB) and a more detailed set of race and ethnicity categories maintained by the U.S. Bureau of the Census (BC). The main purpose of the code set is to facilitate use of federal standards for classifying data on race and ethnicity when these data are exchanged, stored, retrieved, or analyzed in electronic form. At the same time, the code set can be applied to paper-based record systems to the extent that these systems are used to collect, maintain, and report data on race and ethnicity in accordance with current federal standards.

THO: Percy C, VanHolten V, and Muir C, editors. International Classification of Diseases for Oncology. Second Edition. Geneva: World Health Organization; 1990. The ICD-9 neoplasm structure did not include morphology and there was a growing interest by physicians to establish a coding system for morphology. ICD-O is used in cancer registries (and other related areas) for coding the topography (site) and morphology of a neoplasm. The topography code uses similar categories as ICD-10 for malignant neoplasms allowing greater specificity for the site of non-malignant neoplasms than in ICD-10. The topography code consists of an alphabetic character (the letter C) followed by two numeric digits, a decimal point, and a numeric digit. The morphology code consists of a 6-digit numeric code which consists of three parts: histologic type (4-digit), behavior code (1-digit), and grading or differentiation (1-digit). ICD-O-2 is used for tumors diagnosed prior to 2001.

THO: International Standards Organization codes for the representation of names of languages. ISO 639 provides two sets of language codes, one as a two-character code set (639-1) and another as a three-character code set (639-2) for the representation of names of languages. ISO 639-3, Codes for the representation of names of languages - Part 3: Alpha-3 code for comprehensive coverage of languages, is a code list that aims to define three-letter identifiers for all known human languages.

THO: International Standards Organization standard 3166 contains 3 parts. Part 2 contains a complete breakdown into a relevant level of administrative subdivisions of all countries listed in ISO 3166-1. The code elements used consist of the alpha-2 code element from ISO 3166-1 followed by a separator and a further string of up to three alphanumeric characters e. g. DK-025 for the Danish county Roskilde.

THO: ISO's currency codes, which are based on the ISO country codes are published in the standard ISO 4217:2008 Codes for the representation of currencies and funds. This International Standard specifies the structure for a three-letter alphabetic code and an equivalent three-digit numeric code for the representation of currencies and funds. For those currencies having minor units, it also shows the decimal relationship between such units and the currency itself.

THO: Logical Observation Identifiers Names and Codes (LOINC®) provides a set of universal codes and names for identifying laboratory and other clinical observations. One of the main goals of LOINC is to facilitate the exchange and pooling of results for clinical care, outcomes management, and research. LOINC was initiated by Regenstrief Institute research scientists who continue to develop it with the collaboration of the LOINC Committee. The LOINC table, LOINC codes, and LOINC panels and forms file are copyright © 1995-2011, Regenstrief Institute, Inc. and the LOINC Committee and available at no cost (http://loinc.org) under the license at http://loinc.org/terms-of-use. The laboratory portion of the LOINC database contains the usual clinical laboratory categories of chemistry, hematology, serology, microbiology (including parasitology and virology), toxicology; as well as categories for drugs and the cell counts, antibiotic susceptibilities, and more. The clinical portion of the LOINC database includes entries for vital signs, hemodynamics, intake/output, EKG, obstetric ultrasound, cardiac echo, radiology report titles, pulmonary ventilator management, document and section titles, patient assessment instruments (e.g. Glascow Coma Score, PHQ-9 depression scale, CMS-required patient assessment instruments), and other clinical observations.

THO: RxNorm provides standard names for clinical drugs (active ingredient + strength + dose form) and for dose forms as administered to a patient. It provides links from clinical drugs, both branded and generic, to their active ingredients, drug components (active ingredient + strength), and related brand names. NDCs (National Drug Codes) for specific drug products (where there are often many NDC codes for a single product) are linked to that product in RxNorm. RxNorm links its names to many of the drug vocabularies commonly used in pharmacy management and drug interaction software, including those of First Databank, Micromedex, MediSpan, and Multum. By providing links between these vocabularies, RxNorm can mediate messages between systems not using the same software and vocabulary.RxNorm is one of a suite of designated standards for use in U.S. Federal Government systems for the electronic exchange of clinical health information.
