Final answer:
The ICD-9-CM classification begins with 0 and continues through 9 and one additional category, which is called V codes.
Step-by-step explanation:
The ICD-9-CM classification system encompasses a comprehensive range of codes, starting from 001 through 999, providing a numerical framework for categorizing diseases, injuries, and medical conditions. This numerical structure facilitates the organization and retrieval of health information for billing, statistical, and research purposes.
Each three-digit code represents a specific category or condition, with further specificity achieved through additional digits when required. While the primary range extends from 001 to 999, certain sections may have subcategories, allowing for a more detailed classification.
The ICD-9-CM coding system serves as a vital tool in healthcare for standardized communication and documentation of diagnoses and procedures.
