The short version: Eleos Health and Adentris both use AI in behavioral health documentation, but they solve different halves of the problem. Eleos is best known for ambient AI that drafts progress notes from the session and for compliance scanning across notes. Adentris is a revenue integrity and documentation compliance layer that reviews notes, however they are written, in real time before the claim is submitted, with SUD-specific rules like ASAM level of care and 42 CFR Part 2 built in and an appeals and denials module included. If your problem is note-writing time, Eleos is built for that. If your problem is denials and audit exposure, that is where Adentris focuses. They can even work together.
Because they emphasize different jobs, the honest comparison is less about which is better and more about which problem you are solving right now. Here is the breakdown.
What Adentris does
Adentris is an AI platform for revenue integrity and documentation compliance built specifically for behavioral health and SUD programs. It works on top of the EHR you already run, connecting through an API or HL7 where one exists (for example Alleva, Pimsy, Kipu, Epic, or Athenahealth) and through a secure web agent where it does not, so there is no migration. It reviews notes in real time and flags the elements that get behavioral health claims denied before the claim is submitted: medical necessity, ASAM level-of-care justification, treatment plan updates, group therapy attendance, service units, signature timing, and 42 CFR Part 2 consent. When something is missing, it drafts the correction for the clinician to accept, and it pairs documentation review with an appeals and denials module. Adentris is not a scribe: it does not write the note, it makes sure the note will get paid. Adentris is HIPAA compliant and SOC 2 certified, with 42 CFR Part 2 controls and BAAs in place.
What Eleos Health does
Eleos Health is a well-funded AI company built for behavioral health. It is best known for ambient AI that generates progress notes from the session, reducing the time clinicians spend writing documentation, and it also offers compliance capabilities that review notes at scale and surface clinical insights from sessions. For organizations whose primary goal is to cut documentation time and standardize note quality across a large clinical team, Eleos is a strong, established option.

Which should you choose?
Start from the problem you are solving. If your clinicians are spending too long writing notes and you want ambient documentation that drafts the note from the session, Eleos is built for that. If your problem is that claims are denied and audits find gaps, and you want a layer that catches a missing medical necessity statement, an unjustified ASAM level of care, or a missing 42 CFR Part 2 consent and drafts the fix before the claim goes out, that is what Adentris is built for. The two are not mutually exclusive. A program can use an ambient scribe to generate the note and Adentris to verify it will be paid and to defend it when a payer pushes back. For SUD programs specifically, the depth on ASAM and Part 2, the real-time pre-submission timing, and running on any EHR through a secure web agent are the practical differences.
- Choose Eleos Health if your priority is cutting documentation time with ambient note generation and standardizing note quality across a large clinical team.
- Choose Adentris if your problem is denied claims and audit exposure, and you want the note checked against payer and regulatory denial criteria before submission, with ASAM and 42 CFR Part 2 depth and an appeals workflow, on any EHR.
Adentris as an Eleos alternative for revenue integrity
If your program uses Eleos, or is evaluating it, and the gap you feel is not note-writing time but denials, underpayments, and audit exposure, that is a different job. Adentris focuses on the revenue integrity side: it checks whether the documentation supports the claim, flags the specific behavioral health and SUD elements that drive denials, drafts the correction before submission, and pairs that with an appeals and denials workflow. It runs on any EHR through an API, HL7, or a secure web agent, so it fits alongside an ambient scribe or in place of a general compliance scan. For programs that already generate notes well but still lose claims, it is a natural complement or alternative.
How Adentris helps
For behavioral health and SUD organizations, the biggest revenue leak is documentation, and it is specific: medical necessity that was never shown, missing ASAM justification, a Part 2 consent that was not captured. Adentris reviews every chart in real time inside your existing EHR and flags exactly those gaps before the claim is filed, then drafts the fix, and it pairs that with an appeals and denials module so compliance and revenue integrity live in one place. In practice that means fewer denied claims, less audit exposure, and far less time spent reworking documentation after a payer pushes back. Adentris is HIPAA compliant and SOC 2 certified, with 42 CFR Part 2 controls and BAAs in place. To see it on your own charts, book a 30-minute call with our team.
The bottom line
For cutting documentation time across a large team, Eleos is a strong fit. For getting behavioral health and SUD claims paid, Adentris reviews the note before submission, drafts the fix for ASAM and Part 2 gaps, and handles appeals, and the two can run together.

Frequently asked questions
What is the difference between Adentris and Eleos Health?
Eleos Health is best known for ambient AI that drafts progress notes from the session, plus compliance scanning, so it reduces documentation time and standardizes notes. Adentris is a revenue integrity and documentation compliance layer that reviews notes in real time before the claim is submitted, drafts corrections, and has SUD-specific rules like ASAM and 42 CFR Part 2 and an appeals module built in. Eleos helps write the note; Adentris makes sure it gets paid.
Can Adentris and Eleos Health be used together?
Yes. They solve different halves of the problem, so a program can use Eleos Health to generate the progress note and Adentris to verify the documentation supports the claim and to handle appeals. Adentris reviews the note however it was written, so it fits alongside Eleos Health.
Is Adentris a good alternative to Eleos Health?
For programs whose problem is denials and audit exposure rather than note-writing time, yes. Adentris focuses on catching and correcting the behavioral health and SUD gaps that drive denials before submission, with ASAM and 42 CFR Part 2 built in and an appeals and denials module, and it runs on any EHR without a migration.
Which is better for a substance use disorder program?
For SUD, the claims that get denied usually turn on ASAM level of care, medical necessity, and 42 CFR Part 2, which Adentris is built around with real-time, pre-submission review and drafted corrections. Eleos Health is strong for ambient note generation across behavioral health. Programs that want SUD-specific compliance depth and denials support often lean Adentris.
