ix PEDIATRIC ICD-10-CM 2019: A MANUAL FOR PROVIDER-BASED CODING 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. Guidelines that are bold have been revised or added for 2019. Guideline updates for the current year in both the front matter and chapter-specific guidelines are printed in bold. 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.” ICD_10-4th_ed.indb 9 8/16/18 5:33 PM
