B&C Chapter 6: ICD-10-CM Coding Flashcards
adverse effect
development of a pathologic condition that results from a drug or chemical substance that was properly administered or taken.
benign
not cancerous.
carcinoma (Ca) in situ
a malignant tumor that is localized, circumscribed, encapsulated, and noninvasive (has not spread to deeper or adjacent tissues or organs).
comorbidity
concurrent condition that coexists with the first-listed diagnosis (outpatient care) (or principal diagnosis for inpatient care), has the potential to affect treatment of the first-listed diagnosis (outpatient care) (or principal diagnosis for inpatient care), and is an active condition for which the patient is treated and/or monitored.
complication
condition that develops after outpatient care has been provided or during an inpatient admission.
computer-aided coding (CAC)
see computer-assisted coding (CAC).
computer-assisted coding (CAC)
uses a natural language processing engine to “read” patient records and generate ICD-10-CM and HCPCS/CPT codes.
contiquous sites
also called overlapping sites; occurs when the origin of the tumor (primary site) involves two adjacent sites.
Cooperating Parties for ICD-10-CM/PCS
AHA, AMA, CMS, and NCHS organizations and agencies that approve official guidelines for coding and reporting ICD-10-CM and ICD-10-PCS.
encoder
automates the coding process using computerized or web-based software; instead of manually looking up conditions (or procedures) in the coding manual’s index, the coder uses the software’s search feature to locate and verify diagnosis and procedure codes.
encounter
face-to-face contact between a patient and a health care provider (e.g., physician, nurse practitioner) who assesses and treats the patient’s condition.
essential modifier
see subterm.
evidence-based coding
coding auditor clicks on codes that CAC software generates to review electronic health record documentation (evidence) used to generate the code.
first-listed diagnosis
reported on outpatient claims (instead of inpatient principal diagnosis); it reflects the reason for the encounter, and it is often a sign or symptom.
general equivalence mapping (GEM)
translation dictionaries or crosswalks of codes that can be used to roughly identify ICD-10-CM/PCS codes for their ICD-9-CM equivalent codes (and vice versa). See also legacy coding system.
iatrogenic illness
illness that results from medical intervention (e.g., adverse reaction to contrast material injected prior to a scan).
ICD-10-CM coding conventions
general coding rules that apply to the assignment of codes, independent of official coding guidelines.
and
when two disorders are separated by the word “and,” it is interpreted as “and/or” and indicates that either of the two disorders is associated with the code number.
brackets
used in the index to identify manifestation codes and in the index and tabular list to enclose abbreviations, synonyms, alternative wording, or explanatory phrases.
code also
ICD-10-CM tabular list instruction that indicates two codes may be required to fully describe a condition with sequencing depending on circumstances of the encounter.
code first underlying disease
appears when the code referenced is to be sequenced as a secondary code; the code, title, and instructions are italicized.
code first underlying disease, such as
see code first underlying disease.
code, if applicable, any casual condition first
requires casual condition to be sequences first if present; a casual condition is a disease that manifests (or results in) another condition.
colon
used after an incomplete term and is followed by one or more modifiers (additional terms).
default code
listed next to a main term in the ICD-10-CM alphabetic index and represents the condition that is most commonly associated with the main term or is the unspecified code for the condition.
due to
located in the index in alphabetical order to indicate the presence of a cause-and-effect (or casual) relationship between two conditions.
eponym
diseases and procedures named for people, such as Barlow’s disease.
etiology and manifestation rules
include the following notes in the ICD-10-CM Tabular List of Diseases and Injuries: Code first underlying disease; Code first underlying disease, such as; Code, if applicable, any casual condition first; Use additional code; and In diseases classified elsewhere.
Excludes1 note
a “pure” excludes, which means “not coded here” and indicates mutually exclusive codes; in other words, two conditions that cannot be reported together.
Excludes2 note
means “not included here” and indicates that although the excluded condition is not classified as part of the condition it is excluded from, a patient may be diagnosed with all conditions at the same time; therefore, it may be acceptable to assign both the code and the excluded code(s) together if supported by medical documentation.
in
located in alphabetical order blow the main term; to assign a code from the list of qualifiers below the word “in,” the provider must document both conditions in the patient’s records; ICD-10-CM classifies certain conditions as if there were a cause-and-effect relationship present because they occur together much of the time, such as pneumonia in Q fever.
in diseases classified elsewhere
indicates that the manifestation codes are a component of the etiology/manifestation coding convention.
includes note
appear below certain tabular list categories to further define, clarify, or provide examples.
manifestation
condition that occurs as the result of another condition; manifestation codes are always reported as secondary codes.
NEC (not elsewhere classifiable)
means “other” or “other specified” and identifies codes that are assigned when information needed to assign a more specific code cannot be located.
NOS (not otherwise specified)
indicates that the code is unspecified; coders should ask the provider for a more specific diagnosis before assigning the code.
other and other specified code
assigned when patient record documentation provides detail for which a specific code does not exist in ICD-10-CM.
parentheses
enclose supplementary words that may be present or absent in the diagnostic statement, without affecting assignment of the code number.
see
directs the coder to refer to another term in the index to locate the code.
see also
located after a main term or subterm in the index and directs the coder to another main term (or subterm) that may provide additional useful index entries.
see category
instruction directs the coder to the ICD-10-CM tabular list, where a code can be selected from the options provided there.
see condition
directs the coder to the main term for a condition, found in the index.
Table of Drugs and Chemicals
alphabetical index of medicinal, chemical, and biological substances that result in poisonings, adverse effects, and underdosings.
Table of Neoplasms
alphabetical index of anatomic sites for which there are six possible codes according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature.
unspecified codes
assigned because patient record documentation is insufficient to assign a more specific code.
use additional code
indicates that a second code is to be reported to provide more information about the diagnosis.
with
when codes combine one disorder with another (e.g., code that combines primary condition with a complication), the provider’s diagnostic statement must clearly indicate that both conditions are present and that a relationship exists between the conditions.
ICD-10-CM Diagnostic Coding and Reporting Guidelines for Outpatient Services - Hospital-Based Outpatient Services and Provider-Based Office Visits
developed by the federal government, outpatient diagnoses that has been approved for use by hospitals/providers in coding and reporting hospital-based outpatient services and provider-based office visits.
ICD-10-CM Index of Diseases and Injuries
an alphabetical listing of terms and their corresponding codes, which include specific illnesses, injuries, eponyms, abbreviations, and other descriptive diagnostic terms.
ICD-10-CM Index to External Causes of Injury

chronological list of codes contained within 22 chapters, which are based on body system or condition.
ICD-10-CM/PCS Coordination and Maintenance Committee
responsible for overseeing all changes and modifications to ICD-10-CM (diagnosis) and ICD-10-PCS (procedure) codes; discusses issues such as the creation and update of general equivalence mappings (GEMs).
ICD-10-PCD Official Guidelines for Coding and Reporting
prepared by CMS and NCHS and approved by the cooperating parties for ICD-10-CM/PCS; contain rules that were developed to accompany and complement official conventions and instructions provided in ICD-10-PCS; adherence when assigning procedure codes is required under HIPAA.
