for Vol 1 & 2 – Alphabetical Index (Volume 3) • Comprehensive alphabetical index of diseases and conditions found in DRG theWorkshop Tabular List Belgrade, 18-22.November 2013. 27 ICD-10 – Volume 1 – ICD-10 is a variable-axis classification • epidemic diseases • constitutional or general diseases • local diseases arranged by site • developmental diseases • injuries – 3 main elements to the structure • 3 volumes • 22 chapters • alphanumeric codes DRG Workshop Belgrade, 18-22.November 2013. 28 ICD-10 – Volume 1 • Tabular List – Volume 1 – 22 broad groupings of diseases and injuries called chapters, I-XXII (roman numerals) – Within the chapters, codes are divided up into blocks of 3 character categories (usually by site or type of disease) DRG Workshop Belgrade, 18-22.November 2013. 29 Structure of the ICD-10 code – In ICD-10 the 4 character code consists of J45.9 First character A to Z Followed by 2 digits Lastly Another digit Then a point DRG Workshop Belgrade, 18-22.November 2013. 30 Special groups – The following six chapters are special groups of diseases and conditions which are not included in the chapters organised by anatomical site • • • • • • infections cancer pregnancy newborns congenital conditions injuries – These 6 chapters have priority, have precedence over anatomical site chapters DRG Workshop Belgrade, 18-22.November 2013. 31 Inclusion Terms – May be listed under block and code titles – additional examples and synonyms of the diagnoses and diagnostic terms that are classified there • They do not include every possible diagnosis or term – as a guide only • Not always in the alphabetic index DRG Workshop Belgrade, 18-22.November 2013. 32 Exclusion Terms – Found at chapter, block, category or code title level • Important warnings to coders that if the condition being coded is listed in the exclusion terms it may not be coded under that code DRG Workshop Belgrade, 18-22.November 2013. 33 Punctuation [ ] Square brackets – used to enclose synonyms, abbreviations, alternative words ( ) Parentheses are used in the normal way to enclose additional information or examples of codes May be used to enclose nonessential modifiers – the presence or absence of these terms in the diagnosis has no effect on the selection of the code : Colons – a term in an inclusion or exclusion list followed by a colon means that the term is incomplete { } Braces – link a series of terms, each of which is modified by the term to the right of the brace DRG Workshop Belgrade, 18-22.November 2013. 34 Annotations † Dagger symbol • denotes a code describing the aetiology or underlying cause of a disease, should always be sequenced with the appropriate manifestation code * Asterisk symbol • denotes a code describing the manifestation of a disease and should always be assigned with the appropriate aetiology code DRG Workshop Belgrade, 18-22.November 2013. 35 Words and abbreviations – NEC Not elsewhere classified • Used in code and category titles to warn the coder that there may be another, better or more specific code in the classification • If there is more precise information about the condition, then look for a more specific code – NOS Not otherwise specified • This means ‘unspecified’ • Codes that contain terms followed by NOS can be used when there is not enough information to assign a more specific code DRG Workshop Belgrade, 18-22.November 2013. 36 Words and abbreviations cont. – ‘AND’ in code titles • In the tabular list of diseases, ‘and’ means ‘and/or’ • This code title means that under H21.3 you can code diagnoses of ‘cyst of iris’ OR ‘cyst of ciliary body’ OR ‘cyst of anterior chamber’ OR a combination of the three • The use of ‘and’ to mean ‘and/or’ only occurs in the Tabular List (Vol 1)DRG Workshop Belgrade, 18-22.November 2013. 37 Other and unspecified codes – There is not always a separate heading for each disease – Most of the codes have 4 characters – a letter, 2 numbers, a decimal point and then another number – The 4th characters of ‘8’ & ‘9’ are residual codes: .8 = other .9 = unspecified – You must be directed to ‘other’ and ‘unspecified’ codes by the index DRG Workshop Belgrade, 18-22.November 2013. 38 Aetiology and manifestation • Known as dagger asterisk system – For certain conditions, it is important to identify both the aetiology (underlying disease) and the manifestation (resulting condition) – Provides further information for morbidity coding Dagger = aetiology G30.0† Alzheimer’s disease with early onset F00.0* Dementia in Alzheimer’s disease with early onset Asterisk = manifestation DRG Workshop Belgrade, 18-22.November 2013. 39 Alphabetical Index – Volume 2 – Lists diagnostic terms and their corresponding code numbers from the tabular list – Contains many more terms than those appearing in the tabular list – Three sections: • Alphabetic index of diseases and nature of injury • External causes of injury • Table of drugs and chemicals DRG Workshop Belgrade, 18-22.November 2013. 40 Conventions • Lead terms – main term, first place to look in index, usually the name of a disease or condition, not a site • Essential modifiers – found under the lead term (subterms), with a hyphen in front. May be essential modifiers under subterms, down to five indents • Nonessential modifiers – May be found after a lead term or subterm, in parentheses ( ). Have no effect on code selection DRG Workshop Belgrade, 18-22.November 2013. 41 Conventions cont.
