Agentic Index
CodaMetrix vs Fathom (2026)
The two most externally validated autonomous coding vendors, which makes this the shortlist for a lot of health systems. That verdict is the Agentic Index coverage score, graded from each vendor's own published materials.
CodaMetrix carries the 2026 Best in KLAS ranking for autonomous coding, Epic Toolbox designation, Mass General Brigham provenance and more than 220 hospitals at 96 percent plus automation. Fathom carries KLAS validated 90 percent plus automation, HITRUST i1 certification and CVS Health Ventures backing, spanning facility, professional fee, coding review and risk adjustment. Close on documented coverage at 6.5 and 6, so decide on institutional fit and workflow breadth rather than on the matrix.
On the Agentic Index healthcare agent ranking, neither CodaMetrix nor Fathom clears the bar, which asks for all five chart loop capabilities documented in full. CodaMetrix does not document security and identity governance in full, nor human oversight and guardrails; Fathom documents one of the five in full. 8 of the 76 vendors in the lane clear it.
