Health network accuracy auditing tools check whether the records, codes and claims coming out of every facility in a network are right. For provider organizations they fall into four groups: access monitoring (Imprivata, Bluesight PrivacyPro), coding and billing audit (MDaudit, Healthicity), chart and documentation review (Adentris, Binario Research) and payer audit response (MRO). No single product does all four. If you work at a health plan and meant network adequacy or directory accuracy, skip to that section below.
This guide is for compliance officers, privacy officers and HIM directors who own audits across hospitals, medical groups and behavioral health programs. It compares seven tools by audit job, timing and evidence trail, with a "Best for" line for each. If you need AI that reads every note and code before the claim goes out, our list of AI-driven EMR auditing tools goes deeper on that one job and compares pre-bill documentation review, CDI and autonomous coding vendors.
The short version
- "EHR audit" covers four separate jobs: access monitoring, chart audit, coding audit and payer audit response. Buy for the job, not the label.
- HIPAA requires audit controls that record and examine system activity, plus regular review of audit logs and access reports. Access monitoring tools make that review possible at the scale of a health network.
- OIG's 2023 compliance guidance says claims audits should include a credentialed clinician's review of medical necessity. Access logs and coding checks can't answer that question alone.
- The biggest split between tools is timing. Some review before the claim goes out, others manage findings and payer requests after the fact.
- Behavioral health and SUD programs carry rules many general tools don't model, such as ASAM level of care and 42 CFR Part 2 consent.
- Network adequacy and provider directory accuracy are health plan audits with their own rules and tools.

We checked every vendor detail below on the company's own site and press releases in November 2026. Products in this market change quickly, so confirm anything that matters to you in a demo.
How we chose
We started from the jobs compliance teams actually run, then picked tools that do one of those jobs as their main product. We're Adentris, and we list ourselves first. We've tried to be plain about where we don't fit and which tool does that job better.
Each tool was judged on these criteria:
- Audit job. Which of the four jobs does it do, and is that its core product or an add-on?
- Coverage. Does it look at every record, or at a sample your auditors pull?
- Timing. Does it review before the claim or disclosure goes out, or afterward?
- Output. Do you get a drafted fix, a report, or an investigation queue?
- Evidence trail. Can you show an auditor what was checked against which rule and who signed off?
- EHR fit. Does it connect to the EHR you run today without a migration?
- Security. Will the vendor sign a BAA and share a SOC 2 report? Ask which type.
Three tools from the earlier version of this page are gone from this list. Attunement now sells clinical case preparation rather than compliance auditing. Brellium and Charta Health moved to our AI EMR auditing list, because their core job is AI review of documentation before billing.
The four kinds of EHR audit, and the rule behind each
Most confusion in this market comes from one word doing four jobs. The table maps each job to the question it answers, the rule that drives it and the team that usually owns it.
| Audit job | Question it answers | Rule behind it | Usual owner | Tools in this guide |
|---|---|---|---|---|
| Access monitoring | Who viewed, changed or exported a record, and was it appropriate? | HIPAA audit controls (45 CFR 164.312(b)) and activity review (164.308(a)(1)(ii)(D)) | Privacy officer | Imprivata, Bluesight PrivacyPro |
| Chart and documentation audit | Does the record support the service and meet payer and regulatory rules? | Payer medical necessity and documentation rules, state Medicaid manuals, 42 CFR Part 2 for SUD records | Compliance, clinical QA | Adentris, Binario Research |
| Coding and billing audit | Do codes and charges match the documentation? | CPT and ICD-10-CM rules, NCCI edits, payer policy | Coding compliance, revenue integrity | MDaudit, Healthicity |
| Payer audit response | Did we answer the ADR, RAC or payer request on time with the right records? | Payer and Medicare contractor record request deadlines | HIM, revenue integrity | MRO, MDaudit Payer Audit Management |
HIPAA's Security Rule is why access monitoring exists. It requires mechanisms that "record and examine activity" in systems that hold electronic PHI, and procedures to "regularly review records of information system activity," such as audit logs and access reports. A large hospital's EHR produces far more access events than anyone can read, so these tools rank the ones worth investigating.
As of November 2026, the Security Rule overhaul proposed in January 2025 hasn't been finalized, so the current text is what applies.
Chart audits answer a different question. OIG's General Compliance Program Guidance says claims reviews and audits should include a review of medical necessity "by an appropriately credentialed clinician." An access log can't tell you that. Neither can a coding check by itself.
1. Adentris
Best for: behavioral health and SUD programs, and any compliance team whose audit risk sits mostly in documentation, that want every active chart checked before claims go out.
Adentris is a chart and documentation audit layer. It reviews every active chart, not a sample, against payer and regulatory rules before billing: medical necessity, ASAM level of care, 42 CFR Part 2, Medicaid and payer documentation rules, treatment plan and signature timing. Each finding cites the rule that fired and comes with a drafted correction for staff to approve.
For compliance leads, Compliance Intelligence gives a live view of open topics, at-risk patients, deadlines and clinician trends. Autonomous Coding reads every claim line against the chart and flags under-coding, missing add-ons such as 90785, modifier errors, NCCI bundles and LCD gaps. It runs on any EHR through API or FHIR, HL7 feeds, a read-only API our agents build where none exists, or the AI Web Agent, usually with no IT project on your side.
AI inference runs inside Microsoft Azure and no patient data goes to external LLM APIs. BAAs are in place, and we hold SOC 2 Type I. At Sobrius Health, a multi-location Virginia SUD provider, the platform was fully live in 60 days, with 100+ active patients under continuous review and 20+ compliance staff using it daily.
Watch-outs: it isn't an access monitoring tool, so pair it with one of the privacy tools below. Its rule library goes deepest in behavioral health and SUD. A multispecialty hospital coding team will still want a coding audit platform for inpatient and facility claims.
2. MDaudit
Best for: health systems, physician networks, regional hospitals and ASCs that want coding audits, billing compliance and payer audit management on one platform.
MDaudit puts billing compliance, coding audits and revenue integrity on a single platform. Its audit workflows automate data pulls and sample sizes for professional, hospital, coder and dental coding quality audits. Payer Audit Management centralizes external audit requests, including Recovery Audit Contractor work and Additional Documentation Requests received through eMDR.
An acquisition MDaudit closed in August 2025 brought in eValuator, which MDaudit says reviews every encounter before billing, and RevID, which analyzes all charge data daily. There's also an AI assistant for auditors called Auditor Assist.
Watch-outs: its strength is billing and coding compliance, not behavioral health clinical rules such as ASAM level of care or Part 2 consent. EHR integration details aren't published, so ask about yours. We compare the two approaches in Adentris vs MDaudit.
3. Healthicity Audit Manager+
Best for: coding and compliance auditors in practices and hospitals who want dedicated software for the reviews they run, including E/M audits.
Healthicity says Audit Manager+ is "built specifically for healthcare auditors." It lets you audit a coder and a provider at once and supports a wide range of claim reviews, including E/M. Its sister product, Compliance Manager, tracks incidents, training evidence and policies, so one vendor covers more of the compliance program than audits alone.
Compliancy Group acquired Healthicity in June 2026, and the site now reads "A Compliancy Group Company."
Watch-outs: it's built around reviews your auditors perform, so ask how much of the chart reading it automates. After the ownership change, ask about the roadmap and contract terms before a multi-year commitment.
4. Imprivata Patient Privacy Intelligence
Best for: privacy officers at hospitals and health networks who must show they review who accessed patient records, across the EHR and other applications.
Imprivata Patient Privacy Intelligence (formerly FairWarning, now combined with Maize Analytics) monitors user access to PHI and uses AI and behavioral analytics to flag likely privacy violations for investigation. It integrates with EHRs, HR systems and Imprivata's access management products. Imprivata also sells a managed privacy service for teams without spare investigators.
This is the tool category built for HIPAA's activity review requirement. Someone has to look at access reports regularly, and a tool that ranks the suspicious events makes that workable across thousands of users.
Watch-outs: it tells you who opened a chart, not whether the note supports the claim. Alert reductions in vendor case studies come from individual customers, so test the tool on your own logs.
5. Bluesight PrivacyPro
Best for: privacy and compliance teams that want automated EHR access auditing with case management for investigations.
Bluesight acquired the patient privacy business of Protenus in January 2025 and renamed it PrivacyPro. Bluesight says the product "audits up to 100% of EHR accesses" and lets investigators review all related incidents in one interface. It markets PrivacyPro as a six-time Best in KLAS solution.
Watch-outs: the same scope limit applies to any access monitor. It watches behavior, not documentation quality. If you're comparing it with Imprivata, run both against the same month of access logs and count the alerts your team would actually work.
6. MRO
Best for: HIM and revenue integrity teams handling a heavy load of payer audits, ADRs, denials and records requests.
MRO is best known for release of information, a service it says KLAS has confirmed 12 years in a row. Its Audit Manager covers the other side of audits. It automates intake, routing, documentation and submission for inbound audits, denials and documentation requests, and MRO says teams can respond to pre-payment audits in days, not weeks. MRO bought Q-Centrix in June 2025 and now sells data abstraction and quality services too.
Watch-outs: it manages the response after a payer asks. It won't stop the documentation gap that triggered the request. For what each federal auditor wants and how fast, see our guide to Medicare and Medicaid audits in behavioral health.
7. Binario Research
Best for: behavioral health treatment centers that want daily chart audits against ASAM, payer and internal standards without changing EHR.
Binario says it will "audit 100% of charts against defined documentation requirements, 365 days a year," checking each chart against ASAM, payer rules and the center's own standards. It runs alongside the existing EHR. The company also sells workflow automation, revenue analytics and a behavioral health CRM, and it reports more than 50 behavioral health centers as customers.
Watch-outs: it's behavioral health only. Its site shows accreditation bodies as logos rather than describing what it maps, so ask which CARF or Joint Commission standards it checks. Ask too whether it drafts the correction or leaves the fix to staff.
How to choose, by who owns the audit
Start with the person who answers for the finding. The right first tool follows from that.
- Privacy officer. Start with access monitoring, Imprivata or Bluesight PrivacyPro. Native EHR audit logs record activity, but they're too large to review by hand.
- Compliance officer. You'll likely need a chart audit tool and a coding audit tool. Pick the chart tool by specialty fit and the coding tool by the claim types you bill.
- HIM director. Pair a coding audit platform with payer audit response, MRO or MDaudit's Payer Audit Management, since ADR deadlines land on your team.
- Revenue integrity lead at a health system. MDaudit is built for your scale and claim mix.
- Behavioral health or SUD program. ASAM level of care, Part 2 consent and treatment plan timing decide most findings, so choose a chart audit tool that models them: Adentris or Binario Research.
Most health networks end up with one tool per job. That's normal. Trouble starts when a team buys one tool and assumes it covers the other three, then learns otherwise from a payer's records request.
Network accuracy and network adequacy audits: the health plan version
If you searched for network accuracy or network adequacy audit tools, you may be on the payer side. These audits test a health plan's provider network, not a provider's charts, and they rest on different rules.
| Audit | Rule | What it tests |
|---|---|---|
| Provider directory accuracy | No Surprises Act, 42 U.S.C. 300gg-115 | Plans verify and update directory data at least once every 90 days and update the public database within 2 business days of a change. They also need a procedure for removing providers they can't verify. |
| Medicare Advantage network adequacy | 42 CFR 422.116 | Time and distance standards and a minimum number of each provider and facility type, varying by county type |
| Medicaid managed care network adequacy | 42 CFR 438.68 | State-set quantitative standards for provider types, including adult and pediatric mental health and SUD providers |
The tools look different too. Quest Analytics, for example, sells network adequacy and directory accuracy products to health plans and says CMS and many state agencies use its software. For providers, the practical point is smaller: answer plan verification requests promptly, because a plan that can't confirm your details has a process for pulling you from its directory.
Common pitfalls to avoid
- Treating an access log as a chart audit. A log shows who opened the record. It says nothing about whether the note will get paid.
- Sampling where errors repeat. A 10-chart sample can miss a template problem copied across an entire site, and that's exactly what a payer's statistical sample may find later.
- Buying a tool that only reports. A finding on a dashboard still needs someone to fix the chart before the claim goes out.
- Forgetting the paper trail. HIPAA requires documentation of required Security Rule activities to be kept for six years (45 CFR 164.316(b)(2)), so keep a record of each access review as well as the raw logs.
- Assuming any tool runs on your EHR. Confirm the connection path for your EHR and version before you sign, so you aren't pushed into a migration.
How Adentris helps
Adentris covers the chart and documentation audit job, and it does that job before billing. We review every active chart against payer and regulatory rules, cite the rule behind each finding and draft the correction for staff to approve, so the gaps a payer auditor would find get fixed first. Compliance Intelligence shows open topics, at-risk patients, deadlines and clinician trends across sites.
If an audit is already coming, our payer audit readiness service runs a mock audit with chart defensibility scoring, extrapolation exposure and an ADR playbook. Read how Documentation Compliance keeps that review running while each patient is on census. To see it on your own charts, book a 30-minute call with our team.

Frequently asked questions
What are health network accuracy auditing tools?
For a provider network, they're tools that check whether records, codes and claims are correct across every facility. They come in four types: access monitoring, chart audit, coding audit and payer audit response. For a health plan, the phrase usually means provider directory accuracy tools, which support the No Surprises Act rule to verify directory data at least every 90 days.
Which EHR platforms are known for strong compliance?
No EHR brand makes an organization compliant by itself. Check the product's listing on ONC's Certified Health IT Product List and confirm it records access activity in a form your privacy team can review. Get a signed BAA too. Most health networks then add separate tools for access monitoring and chart audit, because native audit logs record activity but don't judge it.
What's the difference between an EHR audit log and a chart audit?
An audit log records who viewed, changed or exported a record, and HIPAA requires audit controls plus regular review of that activity. A chart audit checks whether the documentation supports the service billed and meets payer and regulatory rules. You need both, and they use different tools.
How do healthcare compliance tools create defensible review records?
By recording what was checked, against which rule or standard, what was found, who fixed it and when. Look for findings tied to a cited rule, time-stamped corrections with the approver's name, and reports you can export for an auditor. A tool that only shows a score leaves you rebuilding that trail by hand.
How can you monitor healthcare compliance without manual audits?
Automate the review and keep people on the decisions. Access monitoring tools rank suspicious EHR access for investigators, coding platforms screen encounters before billing, and chart audit tools check every record against payer and regulatory rules. OIG's 2023 guidance still expects clinician review of medical necessity in claims audits, so plan for human sign-off on what the software flags.
What are network adequacy audit tools?
They're health plan tools that test whether a provider network meets access standards, such as Medicare Advantage time and distance standards and minimum provider counts under 42 CFR 422.116, or state Medicaid standards under 42 CFR 438.68. They measure the network, not clinical documentation, so they serve a different buyer than EHR audit tools.
