ICD-10-CM, implemented in the U.S. on October 1, 2015, is based on the World Health Organization's international classification and is used to code diagnoses, symptoms, and procedures in all health care settings. The codes, which can be up to seven characters long, facilitate data collection, payment policy, and research.<br /><br />Key sections of the guide include:<br />1. <strong>Understanding ICD-10-CM</strong>: Details on the structure of ICD-10-CM codes, which may have three, four, five, six, or seven characters. The first three characters indicate the diagnosis category, with subsequent characters offering more specifics.<br /><br />2. <strong>Abbreviations, Punctuation, and Symbols</strong>: Definitions and examples are provided for abbreviations like NEC (Not Elsewhere Classifiable) and NOS (Not Otherwise Specified), as well as punctuation like brackets [ ] and parentheses ( ), and symbols indicating the necessity for additional characters.<br /><br />3. <strong>Chapter Specific Coding Guidelines</strong>: Special rules apply based on the chapter of the ICD-10-CM manual, such as specific codes for paralysis depending on whether the side affected is dominant or non-dominant, and guidelines for coding pain, including neoplasm-related pain and chronic pain conditions.<br /><br />4. <strong>Coding Procedure</strong>: Steps include reviewing medical records, identifying the diagnosis in the Alphabetic Index, and ensuring the highest specificity of the code.
