Adonis vs Nym Health
A third-party profile lists Nym's specialties as emergency medicine, radiology, outpatient surgery, outpatient visits, inpatient professional and urgent care, and the vendor says it connects to Epic, Oracle Health and Meditech. Nym says eligible encounters go straight to billing while the rest route to coders with a rationale on each code. Its accuracy claim reads over 95% in a 2024 release and 98% in a later blog, with no audit method attached. Nym raised $47M in October 2024, led by PSG. A radiology group whose coders keep up but whose payers underpay is the wrong buyer for Nym. Adonis sells denial and underpayment recovery, and MedCity names Mount Sinai, Baptist Health South Florida, AdventHealth and ApolloMD as customers. An emergency group working a coding queue takes Nym to its shortlist and leaves Adonis off it.
