Why did the Department of Health and Human Services support the coding change to ICD-10-CM?

The choice indicating that ICD-9-CM content is outdated and limited is correct because the transition to ICD-10-CM was primarily driven by the need for a more comprehensive and contemporary coding system that reflects advancements in medicine and improves the granularity of health data. As medical knowledge and practices evolve, ICD-9-CM, with its limited code set and outdated structure, became increasingly inadequate for capturing the complexities of patient diagnoses and disease management.

ICD-10-CM includes a broader range of codes that allows for more specific classification of diseases, injuries, and clinical conditions. This increased specificity enhances the ability to track and analyze health trends and outcomes, facilitating more effective public health strategies and healthcare planning.

The other options incorrectly emphasize the adequacy of ICD-9-CM or focus on specific state needs without recognizing the overarching issues with the outdated nature of the coding system. Transitioning to ICD-10-CM responds directly to the demand for improved healthcare data quality and specificity, making it a significant advancement in health information standards.
