For substance use disorder programs, 42 CFR Part 2 is not a feature, it is a requirement, and as of February 2026 the updated rule is enforced. The best 42 CFR Part 2-compliant software either enforces Part 2 on top of your existing systems (AI compliance layers that flag missing consents before a claim or disclosure goes out) or builds Part 2 into the record itself (SUD EHRs with consent management, segmentation, and redisclosure notices). Below are the tools that handle Part 2 well in 2026, starting with the AI-driven compliance layer, followed by the leading SUD EHRs.
The short version
- As of February 16, 2026, the 2024 Part 2 final rule is enforced. Old-format consents may no longer be compliant.
- Compliant software must capture and track consent, apply the single-consent model where used, and include the required redisclosure notice.
- AI compliance layers (like Adentris) enforce Part 2 on any EHR; SUD EHRs (Kipu, Alleva, blueBriX) build it into the record.
- The right choice depends on whether you need to add enforcement on top of your EHR or replace the EHR itself.
How we chose
We looked at how directly each tool handles the Part 2 obligations that actually cause problems: capturing a compliant consent before disclosure, tracking revocations, applying the 2024 single-consent model for treatment, payment, and health care operations, carrying the redisclosure and prohibition-on-use notice, and being able to produce the consent that authorized each disclosure on demand. We favored tools purpose-built for behavioral health and SUD over general medical systems, since Part 2 is a SUD-specific rule that general EHRs often miss. This is a general guide, not legal advice; confirm specifics with counsel, and note that state law can be stricter.
What to look for
Part 2 is a SUD-specific rule that general systems often miss. Compliant software should:
- Capture a compliant consent before disclosure and track revocations.
- Apply the 2024 single-consent model for treatment, payment, and health care operations where used.
- Carry the required redisclosure and prohibition-on-use notice.
- Produce the consent that authorized each disclosure on demand.
- Be SUD-specific, not a general medical system that treats these records like ordinary PHI.
- Fit your model: enforcement on top of any EHR, or Part 2 built into the record.

Capabilities and pricing change quickly in this market, so confirm current details with each vendor before you decide.
1. Adentris
Best for: Enforcing Part 2 documentation and consent on top of any EHR, in real time before claims and disclosures.
How it works: Adentris is an AI revenue-integrity and documentation-compliance layer for behavioral health and SUD. It reviews notes and claims in real time and flags the elements that get behavioral health claims denied or that create Part 2 exposure, including a missing or expired 42 CFR Part 2 consent, then drafts the correction and keeps a contemporaneous audit trail. It runs on any EHR through an API, HL7, or a secure web agent, so it adds Part 2 enforcement without a migration.
Key capabilities: 42 CFR Part 2 controls, real-time consent checks, drafted corrections, appeals and denials module, HIPAA and SOC 2, BAAs.
AI: Yes, it is the AI compliance layer that catches missing Part 2 consents before submission.
Best fit: Programs that want Part 2 enforced on top of any EHR, before claims and disclosures.
Strengths:
- Real-time consent checks flag a missing or expired Part 2 consent before submission
- Drafts the correction and keeps an audit trail that shows you had the consent
- Runs on any EHR, with HIPAA, SOC 2, and BAAs
Watch-outs:
- It enforces and checks Part 2 on the documentation; it is not the consent-management EHR of record itself
- It complements your system of record rather than replacing it
2. Kipu Health
Best for: SUD and addiction treatment programs wanting a purpose-built EHR of record with Part 2-aware workflows.
How it works: Kipu is a widely used addiction-treatment EHR with consent management and records workflows built for SUD programs across residential, IOP, PHP, and outpatient care.
Key capabilities: SUD EHR, consent management, addiction-treatment workflows.
AI: Adding AI features over time; core is the EHR of record.
Best fit: SUD and addiction treatment programs that want a purpose-built EHR of record with Part 2-aware workflows.
Strengths:
- Widely used addiction-treatment EHR
- Consent management built for SUD
- Workflows across residential, IOP, PHP, and outpatient
Watch-outs:
- Adopting it is a migration
- AI is partial; enforcement is workflow-based, not a real-time cross-EHR check
3. Alleva
Best for: SUD and behavioral health programs wanting a full EMR across the continuum with ambient AI notes.
How it works: Alleva is a full behavioral health and SUD EMR spanning IOP, PHP, residential, and detox, with Part 2-aware records and Echo, its ambient AI that drafts structured notes from sessions.
Key capabilities: Full EMR, continuum-of-care workflows, ambient AI documentation.
AI: Yes, ambient AI note generation (Echo).
Best fit: Programs that want a full continuum EMR with Part 2-aware records and ambient AI.
Strengths:
- Full EMR spanning IOP, PHP, residential, and detox
- 42 CFR Part 2-aware records
- Echo ambient AI drafts structured notes
Watch-outs:
- An EMR and scribe rather than an independent consent-and-claim compliance reviewer
- Adopting it is a migration
4. blueBriX
Best for: Programs that want configurable, field-level Part 2 controls and consent-aware interoperability.
How it works: blueBriX emphasizes configurable Part 2 compliance, including field-level tagging of SUD data, live consent status, and automated redisclosure notices so records are not shared like ordinary PHI.
Key capabilities: Field-level consent tagging, consent-aware interoperability, redisclosure automation.
AI: Configurable platform; compliance-first.
Best fit: Programs that want configurable, field-level Part 2 controls and consent-aware interoperability.
Strengths:
- Field-level tagging of SUD data
- Live consent status
- Automated redisclosure notices so records are not shared like ordinary PHI
Watch-outs:
- A configurable platform to implement and configure, not a check you drop onto an existing EHR
- Confirm fit with your current system of record
5. Behave Health
Best for: SUD programs wanting an all-in-one EHR and billing platform with Part 2 workflows.
How it works: Behave Health is an all-in-one behavioral health EHR and billing platform for SUD programs, with documentation and compliance workflows across levels of care.
Key capabilities: All-in-one EHR and billing, SUD-specific workflows.
AI: Platform-level automation.
Best fit: SUD programs that want an all-in-one EHR and billing platform with Part 2 workflows.
Strengths:
- All-in-one EHR and billing
- SUD-specific documentation and compliance workflows
- Coverage across levels of care
Watch-outs:
- Platform-level automation rather than a dedicated real-time Part 2 consent checker
- All-in-one adoption is a migration
How to choose
Match the tool to the job:
- Adding Part 2 enforcement on your existing EHR, before claims and disclosures: Adentris.
- A SUD EHR of record with Part 2-aware workflows: Kipu.
- A full continuum EMR with ambient AI: Alleva.
- Configurable field-level Part 2 controls and consent-aware interoperability: blueBriX.
- An all-in-one SUD EHR and billing platform: Behave Health.
This is a general guide, not legal advice. Confirm specifics with counsel, and note that state law can be stricter.
Common pitfalls to avoid
- Relying on old-format consents after February 2026. Pre-2024 forms may no longer be compliant.
- Treating SUD records like ordinary PHI. Without segmentation and a redisclosure notice, records can be shared improperly.
- Having no way to produce the authorizing consent on demand. If you cannot show it, you cannot prove the disclosure was allowed.
- Assuming a general EHR covers Part 2. HIPAA compliance is not Part 2 compliance.
- Forgetting stricter state law. Some states go beyond the federal rule.
How Adentris helps
Adentris builds 42 CFR Part 2 controls into its documentation review. It flags when a required consent is missing before a claim or disclosure goes out, checks that the note reflects a captured, current consent, and keeps the audit trail that shows you had it, on any EHR.

Frequently asked questions
What makes software 42 CFR Part 2 compliant?
It must capture a compliant consent before disclosure, track revocations, apply the 2024 single-consent model for treatment, payment, and health care operations where used, include the required redisclosure and prohibition-on-use notice, and be able to produce the consent that authorized each disclosure. General medical EHRs often miss these SUD-specific requirements.
Do we need a special EHR, or can we add Part 2 compliance to what we have?
Both approaches exist. SUD EHRs like Kipu, Alleva, and blueBriX build Part 2 into the record, while AI compliance layers like Adentris enforce Part 2 on top of any EHR by flagging missing consents and documentation gaps before submission. If replacing your EHR is not on the table, a compliance layer adds enforcement without a migration.
When did enforcement of the new Part 2 rule begin?
Enforcement of the updated 42 CFR Part 2 requirements began on February 16, 2026, two years after the 2024 final rule took effect on April 16, 2024. Old-format consents may no longer be compliant.
Does HIPAA compliance mean we are Part 2 compliant?
No. Part 2 is stricter than HIPAA for substance use disorder records: it governs consent, segmentation, and redisclosure differently. A HIPAA-compliant general EHR can still miss Part 2 requirements.
What changed with the 2024 Part 2 final rule?
It aligned Part 2 more closely with HIPAA, allowed a single patient consent for all future treatment, payment, and health care operations, and updated notice requirements. Enforcement began February 16, 2026, so pre-2024 consent forms may no longer be compliant.
