Quiz 3: The Coding Process

"The International Classification of Diseases (ICD) system" was developed by the World Health Organization (WHO). This classification is important for classifying and coding the mortality data obtained from the death certificate. The 9CM represents the 9 th revision or clinical modification that was made in the ICD in the United States of America. The ICD-9-CM Volume 1 format contains Tabular List of Diseases having 17 chapters that classify diseases. The numerical value for use as codes lies between 001 to 999.9 and injuries, two supplemental classifications, namely external causes of injury and poisoning and four appendices. ICD-9-CM Volume 2 contains three different sections. The first section is "Index to Diseases." This section contains two official tables that make it easier to code hypertension and neoplasms. The second section is "Table of Drugs and Chemicals" This table is used as a reference for coding the side- effects and poisonings associated with chemicals, medicines, and biological substances. The third section is "Index to External Causes (E codes)." This index is helpful to mark it with a tab as a reminder of its usefulness. ICD-9-CM volume 1 has a tabular list of diseases and ICD-9-CM volume 2 has an index of diseases.

D

The International Classification of Diseases (ICD) system was developed by the World Health Organization (WHO). This classification is important for classifying and coding the mortality data obtained from the death certificate. The 9CM represents the 9 th revision or clinical modification that was made in the ICD in the U.S.A. There are three different volumes of ICD-9-CM. ICD-9-CM volume 1 has a tabular list of diseases and ICD-9-CM volume 2 has an index of disease, table of drug and chemicals, and the index to external causes. The knowledge that the coder should have for properly coding ICD-9-CM volume 1 and 2 are as follows: • The coder should be able to understand the proper and sequential use of the alphabetical index and tabular list. • The coder should be able to locate terms within the Alphabetical Index. • The coder should be able to code in a specific manner, coding up to 3, 4 or 5 digits and knowing how to tell the specificity within the Tabular List • The coder should be able to select diagnosis codes and V-codes • Proper signs and symptoms must be used for coding, and sometimes multiple coding for a single condition can be performed. The process of coding from ICD-9-CM volume 1 and 2 is as follows: • During the coding process, the coder should first read the complete case and identify the keywords in the case study. • The coder should code the diagnosis as well as code the procedure. • The coder should link the code of procedure with one or more diagnosis code for justifying the need for the procedure. • The coder should back code and double check the procedure. ICD-9-CM volume 1 has a tabular list of disease, and ICD-9-CM volume 2 has an index of disease. The coder should read the complete case and then code the keywords in the case study. The coder should code the diagnosis as well as the procedure.
