Coding ICD-9-cm Chapter 2

NOS stands for "Not Otherwise Specified" in ICD-9-CM. This term is used when there is no specific code available to accurately classify a particular condition or diagnosis. It is used to indicate that the information provided is not sufficient to assign a more specific code. NOS is a common abbreviation used in medical coding to indicate a lack of further specificity.

E Codes are used to describe external causes of injury/poisoning, site of incident, and procedures as the cause of an abnormal reaction. These codes provide additional information about the circumstances surrounding an injury, such as the location, cause, and nature of the incident. They are important for tracking and analyzing injury trends, identifying potential hazards, and developing preventive measures. E Codes are not related to extenuating circumstances, extra descriptors, or exercise methods after an injury.

NEC is the acronym for "Not Elsewhere Classifiable." This term is used in medical coding to indicate that a specific condition or diagnosis does not fit into any other existing category or classification. It is used when there is not a more specific code available to accurately describe the condition.

ICD-9-CM codes are updated annually to ensure that the coding system reflects the most current medical practices and terminology. This regular updating allows healthcare providers to accurately document and classify diagnoses and procedures for billing, research, and statistical purposes. By updating the codes annually, any new diseases, conditions, or procedures can be included, while outdated or obsolete codes can be removed. This helps to maintain the accuracy and relevance of the coding system in the ever-evolving field of healthcare.

Coding is defined as transforming written descriptions into numerical designations. This process involves assigning specific codes or symbols to represent different concepts or variables. Coding is commonly used in various fields such as computer programming, data analysis, and research. It allows for efficient data organization, analysis, and communication by converting qualitative information into quantitative data that can be easily processed and interpreted.

Diabetes mellitus is not an adverse effect of a drug. Adverse effects refer to negative or unwanted reactions that occur as a result of taking a medication. Examples of adverse effects mentioned in the options include rash, fever, and shortness of breath, which can occur as a result of drug intake. However, diabetes mellitus is a chronic medical condition characterized by high blood sugar levels and is not caused by drug intake. Therefore, diabetes mellitus is not an adverse effect.

436 is a category because it refers to a general group or class of something. It does not specify any subcategories or subclasses within that group.

The given answer "diagnosis code" is correct because in the context of medical coding, a diagnosis code is used to identify and classify a patient's medical condition or disease. It is a specific alphanumeric code that represents the diagnosis made by the healthcare provider. On the other hand, a procedure code is used to identify and classify the specific medical procedure or treatment performed on the patient. Since the question does not provide any information about a procedure, the correct answer is the diagnosis code.

ICD-9-CM codes are used for medical billing and coding purposes. These codes must be supported by documentation in the medical record, which means that there should be clear and detailed documentation of the patient's condition or diagnosis in the medical records. This documentation serves as evidence and justification for assigning the specific ICD-9-CM code. Without proper documentation, it would be difficult to accurately assign the appropriate code for billing and coding purposes.

The term "777.1" is being classified or categorized into a more specific group or division, which is referred to as a subcategory.

The words contained within the brackets [ ] provide the coder with synonyms, alternative wording, explanatory phrases, and abbreviations. These words can be used to enhance the understanding of the code or provide different ways of expressing the same concept. They can also be used to provide additional information or shorten lengthy terms.

The given answer "procedure code" suggests that the number "51.10" is most likely referring to a specific code used to identify a medical procedure. A procedure code is a standardized system used in healthcare to classify and identify specific medical procedures or services. This code helps in accurately documenting and billing for the procedure performed. Therefore, it is reasonable to assume that "51.10" is a procedure code rather than a diagnosis code, which is used to identify a specific medical condition or disease.

The correct answer is "codes that always require a 5th digit to fully describe them". This means that these codes cannot be fully understood or identified without the presence of a fifth digit. The fifth digit serves as an essential component in describing and distinguishing these codes from others.

Volume 3 of the ICD-9-CM is used by hospitals to report inpatient procedures. This volume specifically focuses on the classification of procedures and provides codes for surgical and other medical procedures performed in a hospital setting. It is used to accurately document and report the procedures performed on patients during their inpatient stay.

723.0 is classified as a subcategory because it falls under a broader category or classification. A subcategory is a more specific division or subset of a category. In this case, 723.0 is a subcategory within a larger category or classification system.

The correct answer is Vol. 1- Disease: Tabular List, Vol. 2- Disease: Alphabetic Index, Vol. 3- Procedures: Tabular List and Alphabetic Index. These three volumes of ICD-9-CM provide a comprehensive classification system for diseases and procedures. The Disease: Tabular List in Volume 1 contains numerical codes and descriptions for diseases, while the Disease: Alphabetic Index in Volume 2 allows for easy searching of diseases by their names. Volume 3 includes the Tabular List and Alphabetic Index for procedures, providing codes and descriptions for medical procedures. Together, these volumes enable accurate coding and classification of medical conditions and procedures.

The correct answer is "International Classification of Diseases, 9th Revision, Clinical Modification." This acronym refers to a coding system used for classifying and coding medical diagnoses and procedures. It is widely used in healthcare settings for billing, research, and statistical purposes. The "9th Revision" indicates that it is the ninth edition of the classification system. The "Clinical Modification" indicates that it includes additional codes and modifications specific to the United States healthcare system.

Symbols, abbreviations, punctuation, and notations in ICD-9-CM are referred to as conventions. These conventions are established guidelines and rules that dictate how information is represented and communicated within the ICD-9-CM coding system. They ensure consistency and accuracy in the coding process, allowing healthcare professionals to effectively classify and document medical diagnoses and procedures.

The Supplementary Classification of Factors Influencing Health Status and Contact with Health Services is also known as V codes.

The given answer, primary neoplasm, is not included in the Table of Drugs and Chemicals. The other options, suicide attempt, therapeutic use, and accident, are all possible classifications that could be included in the Table of Drugs and Chemicals.

The Department of Health and Human Services, in conjunction with the National Center for Health Statistics, is responsible for maintenance of the diagnosis classifications of the ICD-9-CM, Volume 3.

Nonessential modifiers in the Alphabetic Index of Volume 2, ICD-9-CM are terms enclosed in parentheses that have no effect on the selection of the code listed for the term. These modifiers provide additional information or clarification about the code selection but do not impact the actual code assigned. They are used to further describe the condition or provide additional context, but they do not change the assigned code.

Volume 3 of the ICD-9-CM manual is used by hospitals to report services provided to inpatients. This volume specifically deals with procedures and is used to code and classify inpatient procedures. Volumes 1 and 2 of the ICD-9-CM manual are used for coding and classifying diagnoses and diseases. Therefore, the correct answer is Volume 3.

The correct answer is World Health Organization. The ICD-9-CM manual is a classification system for medical diagnoses and procedures, and it was developed based on a text by the World Health Organization. The World Health Organization is a specialized agency of the United Nations that is responsible for international public health. They develop and publish the International Classification of Diseases (ICD) to provide a standardized system for classifying diseases and other health conditions.

The colon ":" in the Tabular list tells the coder that the terms below it complete the term to make it assignable to a given category. This means that the terms listed below the colon provide additional information or specificity to the main term, allowing the coder to accurately assign a code to a specific category or condition.

The correct answer is Volume 2 because the Table of Drugs and Chemicals is typically found in reference books or manuals that provide information about drugs and chemicals. Volume 2 is likely to be the volume that contains this specific table, as it is common for reference materials to be organized into multiple volumes based on different topics or categories.

ICD-9-CM codes are used to translate the services provided from verbal and narrative descriptions to nationally accepted reporting standards. These codes help in accurately documenting and reporting the medical necessity of the services provided. By using diagnostic codes, healthcare providers can justify the need for specific treatments or procedures based on the patient's condition. This ensures that the services provided are appropriate and necessary for the patient's health.

ICD-O, which stands for International Classification of Diseases for Oncology, contains information about the morphology of neoplasms. Neoplasms refer to abnormal growths or tumors, and the morphology of these neoplasms refers to their structure, characteristics, and cellular composition. Therefore, ICD-O provides codes and classifications specifically for the morphology of neoplasms, allowing for standardized and accurate documentation and coding of cancer-related diagnoses.

V codes and V code descriptions are located in Volume 1 of the ICD-9-CM. The ICD-9-CM is a coding system used to classify and code diagnoses and procedures in healthcare settings. Volume 1 of the ICD-9-CM contains the tabular list of diseases and injuries, including V codes which are used to classify factors influencing health status and contact with health services. Therefore, the correct answer is Volume 1, ICD-9-CM.

Italicized type is used to identify codes that are not usually sequenced as the principal diagnosis. It is a formatting technique used in medical coding to distinguish certain codes from others. It helps coders and healthcare professionals to easily identify and differentiate these codes, ensuring accurate sequencing of the principal diagnosis.
