The short version: Adentris and Charta Health both use AI to review clinical documentation before billing, but they are built for different settings. Charta Health is known for automated pre-bill chart review and autonomous coding that catch coding and documentation gaps across specialties before claims go out. 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 through a secure web agent. If you run a behavioral health or SUD program, that specialty depth is usually the deciding factor.
Both review documentation before the claim goes out, so the comparison comes down to specialty depth, which rules the review understands, and whether denials are handled in the same place. 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 Charta Health does
Charta Health is an AI platform known for automated pre-bill chart review and autonomous coding. Using large language models, it reads provider documentation after a note closes, codes the visit, and confirms that billing codes are supported by the documentation and meet payer-specific guidelines, catching coding and documentation gaps before claims are submitted across a range of specialties. For multispecialty groups and health systems that want AI pre-bill review and coding across many service lines, Charta Health is a strong option.

Which should you choose?
Both catch documentation problems before the claim is submitted, so the real question is specialty depth. Charta Health is built for broad, multispecialty pre-bill review and coding across many service lines. Adentris is built specifically for behavioral health and SUD, where the claims that get denied 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 in the moment, 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 Charta Health if you are a multispecialty group or health system that wants broad, automated pre-bill chart review and coding across many service lines.
- Choose Adentris if you run a behavioral health or SUD program and want documentation reviewed against the specific rules that drive your denials, ASAM, medical necessity, and 42 CFR Part 2, with a paired appeals module, on any EHR.
Adentris as a Charta Health alternative for behavioral health and SUD
If you are evaluating Charta Health for a behavioral health or SUD program, the question is usually specialty depth. Broad multispecialty pre-bill review and coding are valuable, but behavioral health claims are denied for reasons specific to the field: 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 exactly 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 a natural behavioral-health and SUD 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. At Sobrius Health, a multi-site Virginia SUD provider, pre-submission documentation accuracy moved from 73% to 96%. 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.
