Final answer:
To find the ICD-10-CM code G13, you would start in the chapter titled "Diseases of the nervous system" as codes starting with 'G' pertain to this area.
Step-by-step explanation:
If you wanted to locate the ICD-10-CM code G13 in the tabular list, you would start in the chapter titled "Diseases of the nervous system."
This is because codes beginning with the letter G typically pertain to the nervous system, according to the ICD-10-CM (International Classification of Diseases, 10th Revision, Clinical Modification) coding system.
The chapters in the ICD-10-CM tabular list are organized based on an alphanumeric structure that groups related conditions together, and chapter G covers a range of conditions related to the nervous system, differentiating it from other chapters that focus on areas such as musculoskeletal conditions or mental disorders.
