Rules or principles for determingin a diagnosic code when using diagnostic code books, such ase each space, typefaxes, indentations, puctuation marks, symbols, instructional notes, abbreviations, cross-reference notes and specific usage of the words and , with, and due to.
are also supplementary classificatin of coding in which you lookfo exernal casuses of injury rather than disease. The code description describes the circumstances that caused an injury rather thna the nature of the injury. Also used in coding adverse reactions to medicine.
the name of a disease, structure, operation, or procedure, usually derived from the name of a place or a person who discovered or described it first.
refers to the underlying cause of the disease and is sequenced in the first position.
cancer confined to the site of origin without invasion of neighboring tissues.
an adverse effect rathe than a poisoning when drugs such as digitalis, steriod agents adn so on are involved
In the Tabular List may never be sequenced as principalor primary diagnoses.
has the properties of invasion and metastasis.
the residual effect (condition produced) after the acute phase of an illness or injury has terminated
spread or transfer of tumor cells from one organ to another site
a spontaneous new growth o ftissue forming an abnormal mss that is also known as a tumor
not elsewhere classifiable (NEC)
The category number for the term including NEC is to be used with ill-defined terms and only when the coder lacks the information necessary to code the tem in a more specific category.

In Volume 2, the aplhabetic index, the V codes are included in the major section Index of Diseases. Some key workds in patient care that may indicate a V code might be needed are exposure, routine annual examination, admission, historyof , encounter, and vaccination.
Diagnostic coding was developed for:
1. Tracking of disease processes 2. Claissification of causes of mortality 3. Medical research 4. Evaluation of hospital service utilization
