This designation emphasizes its role in unifying various stakeholders across the country to tackle shared challenges, best practices, and advancements within the HIM field. By functioning as a collective entity, NHIMA serves as a platform for discussion and collaboration among health information professionals, ensuring a consistent approach to HIM concerns and facilitating the development of strategies that align with national needs.

This distinction is crucial for understanding NHIMA's role within the healthcare landscape.
