7.1.4Coding schemes

Various fields of data type CE which are used in segments defined both in the current chapter and other chapters, are used to transmit information about diagnoses, observation results, procedures, health outcomes, and drugs administered. Figures 7-2 and 7-3 (which were located in Chapter 2 in previous versions) list some common coding schemes for these types of information. The values in the second column of the table would be used in component 3 (and optionally, component 6) of a CE field to identify the coding scheme used.

WHO rec# drug codes

W1, W2

World Health organization record number code. A unique sequential number is assigned to each unique single component drug and to each multi-component drug. Eight digits are allotted to each such code, six to identify the active agent, and 2 to identify the salt, of single content drugs. Six digits are assigned to each unique combination of drugs in a dispensing unit. The six digit code is identified by W1, the 8 digit code by W2.

WHO rec# code with ASTM extension

Note: The Read and NLM (National Library of Medicine) codes in Table 3 also include drugs. A number of sources of unique drug names exist: British Approved Names (BAN), French-approved nonproprietary names (DCF), and International Nonproprietary name (INN). These sources are now being reviewed. Those that also provide unique codes will be added to the registry of coding systems, using the abbreviations given in parentheses.
