Case Coding Starts Now!

In last week’s article, I recommended that you download all of the primary source files that make up the ICD-10-CM/PCS code books and learn how to use them. This week we begin case coding with the source files, or if you prefer with your ICD-10-CM 2012 reference book. We will start with Chapter 1, infectious disease!

Keys to coding Infectious Disease!

Chapter 1 includes diseases generally recognized as communicable or transmissible. There is a new section called infections with a predominantly sexual mode of transmission (A50-A64). It is important to note that human immunodeficiency virus (HIV) disease is excluded from the range of infection codes.

When coding sepsis or AIDS, it is important to review the Coding Guidelines for categories B90-B94. Codes are to be used to indicate conditions in categories A00-B89 as the cause of sequelae, which are themselves classified elsewhere. Code first the condition resulting from (sequelae), i.e., the infectious or parasitic disease. Bacterial and viral infectious agents (B95-B97) are provided for use as supplementary or additional codes to identify the infectious agent(s) in diseases classified elsewhere, e.g., Index--->, Infection---->, Organism ( ex. Streptococcus). Note that the provider and/or coder is to use additional code for any associated drug resistance (Z16).

For this week’s ICD-10-CM case coding: See Sepsis Case.
