Describe ICD-9-CM
What constitutes each of the three ICD-9 volumes' classifications?
Explanation:
The International Classification of Diseases, 9th Revision (ICD-9) is a coding system used to classify and code diagnoses, diseases, and medical procedures. The three volumes of ICD-9 are organized as follows:
Volume 1: The Tabular List of Diseases and Injuries
- This volume contains a list of diseases and injuries organized numerically by code from 001-999.9. Each code represents a specific diagnosis or condition and is accompanied by a description of the disease or injury. Volume 1 is primarily used for coding diagnoses in inpatient and outpatient medical settings.
Volume 2: The Alphabetic Index of Diseases and Injuries
- This volume contains an alphabetical list of terms and corresponding code numbers. It can be used to locate a specific code based on the diagnosis or condition or to find a diagnosis or condition based on a specific code. Volume 2 is a helpful reference tool for medical coders, physicians, and other healthcare providers.
Volume 3: The Tabular List and Alphabetic Index of Procedures
- This volume contains a list of medical procedures, surgical operations, and diagnostic tests organized by code. Each code represents a specific procedure or test and is accompanied by a description of the system or test—volume 3 primarily principles medical methods in inpatient and outpatient medical settings.
They are used to distinguish between synonyms for the same code inserted at the start of a chapter or section.
The phrase "not elsewhere classified" is used in Volume 2 to indicate that there isn't a separate classification for the condition.
When neither the diagnostic statement nor the health records include the necessary information, "not otherwise stated" is used in Volume 1.
Explanation:
The term "not otherwise specified" (NOS) is often used in Volume 1 of the ICD-9 to indicate that the diagnostic statement or health record does not provide enough information to assign a more specific code. The NOS code is used when the healthcare provider cannot find enough data to give a more specific code to describe a patient's condition or diagnosis. The NOS code is meant to be used as a last resort when no other code is available or appropriate.
