Emergency department (ED) coding refers to the assignment of E/M codes, CPT procedure codes, and ICD-10 diagnosis codes for patient encounters in an emergency department setting. ED coding is high-volume and high-complexity, with encounters frequently involving multiple diagnoses, critical care services, and procedures performed under time pressure with rapid documentation. Accuracy and throughput are both essential. Nym’s autonomous medical coding engine is purpose-built for emergency medicine, processing high volumes of ED encounters in seconds with zero human intervention and routing successfully coded claims directly to billing.
