Final answer:
The ICD-10-CM has been improved with expanded signs and symptoms codes, updated diagnostic codes, and an enhanced classification system that provides enhanced specificity for better medical documentation and public health tracking.
Step-by-step explanation:
The notable improvements in the content and format of the ICD-10-CM include a significant expansion of signs and symptoms codes, which allows for more accurate clinical documentation and facilitates improved patient care by enabling more specific diagnoses. Additionally, the updated diagnostic codes reflect the latest medical knowledge and technological advancements, ensuring that coding and billing practices are up-to-date and accurate. Lastly, the enhancement to the classification system and the enhanced specificity of codes aid in the better tracking of morbidity and mortality statistics, which is crucial for public health monitoring and research. For example, when a patient presents with a viral infection, ICD codes are used throughout the health care system to ensure appropriate testing and treatment.
