Amperos vs Nym Health
Nym's accuracy figure varies by source. A 2024 press release says over 95%, and a later blog cited by an aggregator says 98%, with no audit method for either. The product is autonomous coding that sends successfully coded encounters straight to billing and routes low-confidence ones to coders, with a rationale for each code. A third-party profile lists emergency medicine, radiology, outpatient surgery and urgent care. The vendor reports that Inova cut annual ED coding costs by $1.3M (currency not stated), and Nym's release says Epic's Toolbox designated it Fully Autonomous Coding on August 16, 2024.
Amperos works denied claims and lists ten specialties, from DME/HME and oncology to dental. The vendor says it operates at over 3,000 clinical locations in all 50 states.
An emergency department group's coding manager on Epic buys Nym. A urology or oncology practice with unpaid denials buys Amperos.
