How to Use This Manual
While attempting to stay true to the complete International Classification of Diseases, 10th Revision, Clinical Modification (ICD-10-CM)
manual, Pediatric ICD-10-CM: A Manual for Provider-Based Coding is meant specifically for pediatrics and only includes those conditions
more commonly seen in pediatrics. We have attempted to remove all adult-only conditions as well as those conditions not typically found
in the United States. Because ICD classification is used worldwide, many conditions listed in the official manual are not found in this part
of the world.
Guidelines that are relevant to all pediatric codes are still included. Note that some chapter-specific guidelines will appear at
the beginning of the related chapter when they are overarching to most of that chapter. However, chapter-specific guidelines that are
relevant only at specific category or code levels will be found at those category or code levels. The beginning of each chapter will
reference the category(ies) or code(s) where the guidelines can be found.
We use our own abbreviations throughout that may not appear in ICD-10-CM; however, all abbreviations are defined on the inside
front cover for easy access as you navigate through the manual.
While unspecified codes can still be found throughout and in certain instances will be the most appropriate code, we have removed
nearly every code that uses unspecified laterality. We feel it is important that laterality is documented in nearly all conditions. You will
see a footnote in those chapters where we have specifically left out laterality in nearly all conditions. If you need to report unspecified
laterality for a condition and it is not listed in the chapter, refer to the full ICD-10-CM manual. Those codes will typically have a final
character of 0 (zero) or 9.
Three-character codes still exist in ICD-10-CM. Those will be noted specifically throughout the chapters as well.
In an effort to keep the size of the manual manageable, some codes are only written out fully at the category or subcategory level.
The category or subcategory will be notated with a semicolon (;) and the code will begin with a lowercase letter. For example
A37.0 Whooping cough due to Bordetella pertussis;
A37.00 without pneumonia
A37.01 with pneumonia
At the subcategory level (A37.0) you see the semicolon (;) and at the code levels (A37.00 and A37.01) the codes begin with a
lowercase letter. Therefore, code A37.00 reads, “Whooping cough due to Bordetella pertussis without pneumonia.”
