The short version: Adentris and Phare Health both work on documentation and the claim, but they are built for different settings. Phare Health, now part of R1 RCM, automates inpatient medical coding and pre-bill clinical documentation improvement from full EHR records for hospitals. Adentris is a revenue integrity and documentation compliance layer purpose-built for behavioral health and SUD, with rules like ASAM level of care and 42 CFR Part 2 and an appeals and denials module, running on any EHR. If you are an acute hospital, Phare is built for that. If you run a behavioral health or SUD program, that specialty depth is the deciding factor.
Both work on documentation and the claim, so the comparison comes down to setting and specialty depth. Here is an honest comparison.
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 HIPAA compliant and SOC 2 certified, with 42 CFR Part 2 controls and BAAs in place.
What Phare Health does
Phare Health is an AI-native platform, now part of R1 RCM, that automates inpatient medical coding and pre-bill clinical documentation improvement from full EHR records. Built by a team with health-AI backgrounds, it targets hospital coding and CDI workflows. For hospitals and health systems that want automated inpatient coding and documentation improvement, Phare is a capable option.

| SUD depth | ASAM level of care and 42 CFR Part 2 built in | General acute inpatient focus |
| EHR fit | Any EHR via API, HL7, or a secure web agent (no migration) | EHR integrations |

Which should you choose?
Both aim to get the claim right, so the real question is setting and specialty depth. Phare is built for acute inpatient coding and CDI, reading full EHR records to code and improve documentation. Adentris is built specifically for behavioral health and SUD, where denials turn on ASAM level of care, medical necessity, group therapy attendance, service units, and 42 CFR Part 2 consent. Adentris understands those rules, drafts the correction before submission, pairs review with an appeals and denials module, and runs on any EHR through a secure web agent. For a behavioral health or SUD program, that depth is the practical difference.
- Choose Phare Health if you are a hospital that wants automated inpatient coding and pre-bill clinical documentation improvement from full EHR records.
- Choose Adentris if you run a behavioral health or SUD program and want documentation reviewed against the specialty rules that drive your denials, ASAM, medical necessity, and 42 CFR Part 2, with a paired appeals module, on any EHR.
Adentris as a Phare Health alternative for behavioral health and SUD
If you are evaluating Phare Health for a behavioral health or SUD program, the question is specialty fit. Inpatient coding and CDI built for hospitals are valuable in that setting, but behavioral health claims are denied for field-specific reasons: an unjustified ASAM level of care, a missing medical necessity statement, group therapy attendance and service units that do not line up, or a 42 CFR Part 2 consent that was not captured. Adentris is built around those rules, drafts the fix before submission, pairs it with an appeals and denials workflow, and runs on any EHR through an API, HL7, or a secure web agent, which makes it the purpose-built choice for behavioral health and SUD.
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 acute inpatient coding and CDI, Phare Health is a capable fit. For a behavioral health or SUD program, Adentris brings the specialty depth, ASAM, medical necessity, and 42 CFR Part 2, catches and corrects the gap before submission, and pairs it with appeals, on any EHR.

Frequently asked questions
What is the difference between Adentris and Phare Health?
Phare Health, now part of R1 RCM, automates inpatient medical coding and pre-bill clinical documentation improvement from full EHR records for hospitals. Adentris is a revenue integrity and documentation compliance layer purpose-built for behavioral health and SUD, with ASAM and 42 CFR Part 2 rules and an appeals module, running on any EHR. The main difference is setting and specialty depth: acute inpatient versus behavioral health and SUD.
Can Adentris and Phare Health be used together?
Yes. They solve different halves of the problem, so a program can use Phare Health to automate inpatient coding and CDI 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 Phare Health.
Is Adentris a good alternative to Phare Health?
For programs whose problem is denials and audit exposure rather than inpatient coding and documentation improvement, 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. Phare Health is strong for automated inpatient coding and clinical documentation improvement. Programs that want SUD-specific compliance depth and denials support often lean Adentris.
