Tabular List of Disease and Injuries. | Volume 1 |
What 3 major subdivisions are contained in volume 1? | 1. Classification of Diseases and Injuries 2. Supplementary Classifications (V codes and E codes) 3. Appendices |
Of the 3 major subdivisions contained in volume 1 which subdivision contains 17 chapters that classify conditions according to etiology or by specific anatomical system? | Classification of Diseases and Injuries |
cause of disease | etiology |
Each chapter of volume 1 is structured into what 3 subdivisions? | sections, categories, and subcategories. |
Of the 3 format subdivisions in volume 1 which consists of a group of three-digit categories that represent a single disease entity or a group of similar or closely related conditions? Ex) DISORDERS OF THE THYROID GLAND (240-246) | Section |
From each chapter of volume 1 which format subdivision is a three-digit representation of a single disease entity or a group of similar or closely related conditions? ex) 520 Disorders of tooth development and eruption. | Categories |
From each chapter of volume 1 which format subdivision consists of a fourth-digit to provide more specificity regarding the etiology, site or manifestation. ex) 476.1 chronic larynotracheitis | Subcategory |
Note found in the ICD-10-CM that indicates "Not Included Here." If a patient has both conditions it is acceptable to use both codes to describe the patient's condition. | Exludes2 |
T/F A three-digit code cannot be assigned if a category has been subdivided and fourth digits are available? | True |
Format that provides even greater specificity. Instructions for use of this format appear at the beginning of a chapter, a section, a three-digit category or a fourth-digit category. | Fifth-digit subclassification |
Codes with titles of "other" and "unspecified" | Residual Subcategories |
Residual subcategories titled "other" are easily distinguished b/c the fourth digit is often the #? | 8 |
Codes dedsribiing "unspecified" conditions are usually assigned a fourth digit of what? * In few intances this fourth digit is assigned for both "other" and "unspecified" | 9 |
The two alphanumeric codes (V & E codes)that exist in addition to the main classification for diseases and injuries. | Supplementary Classifications |
Supplementary classification of factors influencing health status and contact with health services. They consist of an alphabetic character followed by two numeric digits, a decimal point, a fourth digit and where applicable a fifth. | (V01-V91)- V Codes ex. V74.2 |
Supplementary classification of external causes of injury and poisoning. They consists of the alphabetic character followed by three numeric digits, a decimal point and a fourth digit. | (E000-E999)-E Codes ex. E953.0 |
Alphabetic Index to Diseases | Volume 2 |
What are the 3 major sections in volume 2? | 1. Index to diseases and injuries 2. Table of Drugs and Chemicals 3. Alphabetic Index to External Causes of Injury and Poisoning (E Codes) |
What section in volume 2 includes the terminology for all the codes appearing in volume 1 of ICD-9-CM. | Index to Diseases and Injuries |
The Alphabetic Index to Diseases and Injuries in Volume 2 employs what three levels of indentations? | 1. Main terms 2. Subterms 3. Carryover lines |
This word is found in the Tubular list and is surrounded by a box. In some instances it can indicate that two codes should be assigned. | Excludes |
These notes are boxed and set in italic type where as the Tabular List notes are located at various levels of the classification system and are not boxed. | Alphabetic Index Notes |
In the Tabular List what are three phrases that are an indication that multiple codes may be required? | "due to," "secondary to," or "with" |
Mandatory multiple coding is identified in the Alphabetic Index with the second code listed in what? The code with this punctuation mark is always sequenced second. | [italic square brackets] |
When writing mandatory multiple codes the 1st code should identify what? While the second code identifies what? | 1. the underlying codition 2. the manifestations or other conditions that occur as a result of the underlying condition. |
Coders should follow what data set when reporting additional diagnoses. | Uniform Hospital Discharge Data Set (UHDDS) |
Equivalent of unspecified. Used only in Volume 1, Tabular List. Codes using this abbreviation for conditions or procedures are assigned only when the diagnosis does not provide enough information to assign a more specific code. | NOS "not otherwise specified" |
A series of terms in parentheses that sometimes directly follow main terms and subterms in the Alphabetic Index to Diseases. Their presence or absence in the diagnosis has no effect on the selection of the codes listed for that main term or subterm. | Nonessential modifiers |
Punctuation mark used to enclose synonyms, alternative wording, abbreviations and explanatory phrases. They are not required as part of the diagnostic statement. They are used for both diseases and procedures, but only in the Tabular List. | [Square Brackets] |
Abbrieviation that simplifies tabular entries and saves printing space by reducing repetitive wording. | Brace} |
Terms should first be located in the Alphabetic Index then the code can be verified by checking what? | Tabular List |
A numerical list of codes divided by chapters | Tabular List |
Punctuation mark used in the Tabular List after an incomplete term that needs one or more of the modifiers following it to make it assignable to a given category. | Colon: |
New to ICD-10-CM this note apears to indicate "Not Coded Here!" It is used when two conditions/codes cannot occur together. | Exludes1 |
