The World Health Organization released ICD-11 in 2019, and countries are progressively adopting it. Understanding the transition is crucial for practicing coders.
ICD-11 offers a more granular, digital-first structure with over 55,000 unique codes compared to ICD-10's ~14,400 — enabling better specificity and global interoperability.
For Indian healthcare BPOs serving US clients, ICD-10-CM remains the operative standard in the near term, but proactive learning of ICD-11 principles gives coders a long-term competitive advantage.
