Telling the whole COVID-19 story in ICD-10-CM: Capturing the inflammatory response

Why This Topic Matters

As COVID-19 clinical understanding evolves, documentation and coding practices must keep pace so coded data more accurately reflects patient severity and supports research, quality reporting, and record integrity.
