Chapters 1 - 4 Flashcards
What does CIHI do?
develop databases, HI standards, identify national health indicators, distribute HI
What is DAD?
Discharge Abstract Database
What is CIHI?
Canadian Institute for Health Information
What is an abstract?
The input document in a software system where all coding information is entered.
All DAD entries and corrections in Alberta are submitted to:
Alberta Health and Wellness
Once health information is reviewed by AH&W, where is it sent to?
CIHI
What are the 2 patient servicing services applied to patients?
- Main Patient Service (decided by HIM professional)2. Physician Service
T or F: Main Patient Service and Physician Service must fall under the same specialty.
False. They may be entirely different, especially in small hospitals where not all services are staffed. Physician specialty isn’t a factor when assigning the main patient service.
What is a Main Patient Service?
Service MOST RESPONSIBLE for pt care during stay.
What must a patient’s age range be to fall under a paediatric patient service?
12 years and under
When is the Newborn General Service assigned?
An infant is only classified under this service in the facility they were BORN IN.
T or F: No chart is created for a stillbirth.
True. No abstract is created by admitting a stillborn; we create the abstract separately to enter data. Mother’s chart would be an Obstetrics Delivered service.
What is the difference between medical and surgical services?
No surgery performed for medical services. Surgical interventions performed for surgical services. *Surgical services are assigned if the attending is a surgeon even if no surgery was performed.
When is Obs Antepartum assigned?
Mother treated for a PREGNANCY-RELATED CONDITION but discharged BEFORE DELIVERY.
When is Obs Postpartum assigned?
During the 42 DAY puerperal or post-delivery period
T or F: Ectopic pregnancies are assigned to Obs Aborted.
False. Ectopic pregnancies are service to gynecology.
T or F: treatment using sutures is serviced to plastic surgery.
True.
T or F: You would service upper respiratory problems to respirology.
False. Upper respiratory issues are serviced to OTOLARYNGOLOGY while lower lung issues are serviced to RESPIROLOGY.
What is the main purpose of coding?
Coding: translating MEDICAL TERMINOLOGY into a CLASSIFICATION SYSTEM that can be easily manipulated for STATISTICAL ANALYSIS and reporting
What are the two components of coding?
- INTERPRETATION of the SOURCE DOCUMENTS (pt chart)2. CODE ASSIGNMENT
What is the difference between ICD-10 and ICD-10-CA?
ICD-10-CA is a Canadian modification of ICD-10. While ICD-10 was developed by the WHO, ICD-10-CA was modified for Canadian use by CIHI. It includes issues that are exclusive or relevant to Canadians, such as injuries caused by skates, skis, and ice.
What is CCI?
CCI stands for Canadian Classification of Health Interventions. They contain codes for INTERVENTIONS such as diagnostic or therapeutic procedures.
T or F: CCI was developed by the World Health Organization.
False. CCI was developed by CIHI.
What are examples of source documents?
Inpatient records, operative reports, emergency reports, ambulatory care reports (bloodwork, xrays, CT, MRIs)
What are 3 factors that influence the interpretation of source documents?
- Physician DOCUMENTATION STYLE (penmanship)2. COMPLETION or INCOMPLETION of record at time of coding3. Coder KNOWLEDGE and EXPERIENCE
What is involved in code assignment?
Code assignment involves choosing and assigning ALPHANUMERIC CODES from ICD and CCI to represent disease and intervention data.
What do we call the use of health data for statistical and reporting purposes?
This is called SECONDARY USE or HEALTH SYSTEM USE (HSU), the goal of which is to improve the health of Canadians and the health care system. This use can determine incidence of disease, resource allocation, opportunities for growth in providing quality of care, education and research.
What is the main purpose of ICD-10?
It is the international classification system for classifying mortality and morbidity data.
What is a classification?
A systemic method of arranging elements based on a particular point of view. ex. Physicians look at health care problems from the POV of medical diagnoses. Nurses look at conditions in relation to specific care needs.
T or F: ICD-10-CA can be based on your point of view.
False. ICD-10-CA is based on the PHYSICIAN POV. i.e. diseases and health related problems as described in a diagnoses.
T or F: Diseases and health-related problems are collectively called CONDITIONS.
True.
T or F: ICD-10-CA isn’t confined to one category.
False. ICD-10-CA is confined to a limited number of MUTUALLY EXCLUSIVE categories. It provides for ONE and ONLY ONE category for each and every possible condition.
What is the difference between statistical classification and a nomenclature/terminology list?
Statistical classification follows the concept of grouping related conditions. A nomenclature/terminology list gives a separate category for each condition and each term used to describe them.
What are the 3 categories in ICD-10-CA?
- SPECIFIC – common diseases2. LESS SPECIFIC – groups of separate but related conditions3. RESIDUAL – less specific, less common, misc conditions. Would be under headings such as “Other congenital malformations of larynx”
What is an axis and what type of axis is involved in ICD-10-CA?
Axis is the CRITERION for which classification is based. ICD-10-CA is a VARIABLE AXIS classification. Ex. axis: local diseases by site (respiratory system). condition: allergic asthma
What are the 2 major structural components in ICD-10-CA?
- Tabular list2. Alphabetical Index
What is the tabular list?
This is the classification itself and where the codes reside. Consists of a NUMERIC LISTING in ALPHANUMERIC ORDER of diagnosis codes, injury codes, etc.
How is the tabular list organized?
It is organized into CHAPTERS (blue), BLOCKS (black), and CATEGORIES (red text).
T or F: There are 25 chapters in the tabular list.
False. There are 23 chapters that correspond to the primary axes of the classification.
Which group of chapters is referred to as the body system chapters?
Chapters 6-14: Local diseases arranged by site
What are the rest of the chapter groups referred to?
Special group chapters.
T or F: When in doubt as to whether a condition is classified to a body system chapter or special group chapter, the special group chapter takes prirority.
True.
The first letter in an ICD10CA code is stands for______.
The chapter. Small chapters share letters, like D (II and III) and H (VII and VIII). Others are so large they require more than one letter.
T or F: U is reserved for temporary placement of newly created categories until a permanent placement is determined.
True.
Why is the beginning of each chapter important?
The beginning of each chapter provides instructions. Ex. When a condition is classifiable to a special group chapter, it takes precedence over assignment to a body system ch.
What are blocks?
Chapters are subdivided into blocks of THREE CHARACTER CATEGORIES. Blocks GROUP one or more adjacent categories into a related group of conditions. Ex. D50-D53 Nutritional anemias.
T or F: You must review instructions at the beginning of a chapter, block and three letter category before confirming your code selection.
True.
What are three character categories?
The code. An alphabetic character followed by two numeric characters.
What are residual categories?
OTHER and UNSPECIFIED categories. Ex. N32 other disorders of bladder
T or F: Most 3 character categories are further subdivided into 4 character categories.
True.
T or F: The fourth character is optional.
False. It is mandatory; the 3 chars can’t stand alone. When a category has been further subdivided, assign all available characters.
What does the “.—” (point dash) symbol mean?
It indicates an INCOMPLETE ICD CODE.
T or F. When the three character category isn’t subdivided, it stands alone.
True. Ex. N40 Hyperplasia of prostate
What is a four character subcategory?
Used to provide more detailed info within a three character category. This fourth character may represent different sites or extent of condition. Ex. K35 Acute appendicitis.
T or F: 3 character categories describe individual diseases within a group while 4 represents a group of conditions.
F. 3= group of conditions. 4 = individual diseases within that group.
What are .8 and .9 fourth character codes generally used for?
Fourth char .8 is used for OTHER conditions within the thee char category while .9 represents UNSPECIFIED ones. These are called residual subcategories. N64.8 Other specified disorders of breastN64.9 Unspecified disorders of breast
What are five- and six- character subcategories?
These provide SUBCLASSIFICATIONS to represent ADDITIONAL AXES. Ex. Anatomical site or episode of caste
What is the alphabetical index?
An alphabetical listing of diseases, injuries, factors influencing health status or other reasons for contact with the health care system. It is a list of DIAGNOSTIC TERMS found in health care documentation.
T or F: The tabular list leads to the alphabetical index.
F. The alphabetical index leads to the codes in the tabular list.
T or F: Alphabetical Index must be referenced first befit the Tabular List.
T.
The alphabetical index consists of what 3 sections?
- Alphabetical Index to Diseases and Nature of Injuries — Index to codes in ALL chapters int he tabular list (binocular 1)2. External Causes of Injury — most codes in the tabular list in CH 20 (bin 2)3. Table of Drugs and Chemicals — index to remaining codes in CH 19 and 20 relating to drugs and chemicals (bin 3)
How is the alphabetical index organized?
It is organized by LEAD TERMS with SECONDARY TERMS indented below.
What are lead terms?
Lead terms indicate the NOUN expressed as the name of a disease, injury, factor influencing health status or reason for contact with health services. Ex. Appendicitis in Acute appendicitis.
What are secondary terms?
These are ADJECTIVES and are lead term MODIFIERS. These may refer to anatomical site, variety or type of disease, etc. ex. Acute in acute appendicitis.
What is a word wheel?
Left of query window that contains alternate spellings or forms of words.
T or F. Secondary terms are listed under lead terms in alphabetical order.
T. Exception: secondary term “with” is almost always listed first.
T or F. Codes are assigned from the alphabetical index.
F. Codes are assigned from the tabular list. Hyperlinks in the AI lead to the possible list of codes. Always refer to the tabular list to review all inclusion notes, exclusion noted and supplemental info.
What are essential modifiers?
Essential secondary terms. These must be present in the documentation before the code can be assigned.
What are nonessential modifiers?
Additional terms in parentheses. The presence/absence of these terms in the source document doesn’t affect code selection.
What does the “next partition hit” icon do?
Small double arrow button to step from LEAD TERM to LEAD TERM.
What does the “next hit” icon do?
Large double arrow button to go from SUBTERM to SUBTERM within a lead term. Regular Ctrl + F
T or F. In some instances the coder must convert adjectival statements into a noun to find an appropriate code.
T. Ex. Deranged joint > Derangement, joint.
T or F. You can conduct a search on a secondary term only.
T. Do this when you can’t find a lead term in the AI and have exhausted all alternative terms
What does “specified NEC” indicate?
Not elsewhere classified. This is searched for as a secondary term when the secondary term can’t be located. The assignment of a sNEC code implies the documentation has described the condition in specific terms that fits with the axis of the category or subcategories but the classification doesn’t prove a depart specific code for the condition.
When do you use sNEC as a secondary term?
When1. A specific term used in documentation isn’t listed as a secondary term2. The term used FITS WITH THE AXIS of the category or subcategory3. The term can’t be assigned to a synonymous term
