Wound.ai
Wound Care
Validates encounter documentation and coding alignment against payer policy during the pre-billing phase, where most wound care denials are created.
Chart.ai audits your charts before claims go out. It flags documentation, coding, and compliance risk, and it finds the revenue you already earned but never captured.

What is Chart.ai?
Chart.ai is Grelin's AI powered chart auditing and revenue intelligence engine. It reviews every chart for documentation gaps, coding risk, and compliance issues, and it surfaces undercoded encounters and missed billable services before a claim is ever created.
The Problem
By the time a denial lands, the mistake is weeks old. The documentation gap, the wrong modifier, the undercoded encounter. All of it was created upstream, inside the chart.
Manual auditing only samples a fraction of charts, and it happens after claims are already out the door. The charts that quietly lose money never get looked at.
Chart.ai changes where the work happens. It reads the chart first, so the problem gets fixed before the claim exists.

The Engine
Chart.ai runs on top of your EHR and RCM stack. It does not replace anything. It adds the upstream visibility your team never had.
01
Reviews each chart for documentation gaps, coding risk, and compliance issues before claims are filed.
02
Identifies undercoded encounters and missed billable services that suppress reimbursement without ever triggering a denial.
03
Surfaces the charts that matter most, so your team spends expert time where the revenue impact is highest.
04
Accuracy improves over time by learning from outcomes across your practices and specialties.
05
Integrates with your existing EHRs and workflows. No system replacement, no workflow disruption.
06
Delivers CFO-ready insight into where revenue is leaking, why it happens, and how to fix it upstream.
Specialty Applications
Every specialty has its own documentation standards, modifiers, and payer logic. Chart.ai powers a family of applications built for the exact rules that decide reimbursement in each modality. Each one is powered by Grelin.
Wound Care
Validates encounter documentation and coding alignment against payer policy during the pre-billing phase, where most wound care denials are created.
Pain Management
Validates authorization requirements, documentation alignment, and coding consistency against payer policy before claims enter the billing workflow.
Durable Medical Equipment
Analyzes documentation, physician notes, and billing data against thousands of DME payer rules and modifier requirements before claims are submitted.
Evaluation & Management
Analyzes physician documentation in real time to flag missing elements needed to support the appropriate E/M level, reducing undercoding across hospital systems.
Behavioral Health
Checks medical necessity, time-based and session coding, authorization, and documentation against behavioral health payer requirements before claims go out.

How it works
STEP 1
Chart.ai connects to your existing EHR. No data migration, no system replacement.
STEP 2
Every chart is analyzed before submission for documentation, coding, and compliance risk, and for missed revenue.
STEP 3
The risk engine ranks charts so your team works the highest-impact items first.
STEP 4
Issues are fixed upstream. Claims go out clean, and earned revenue gets captured.

“Grelin changed how we think about RCM. We are no longer chasing denials, we are preventing them. The financial impact showed up faster than we expected, and our teams finally feel ahead instead of behind.”
Questions
Chart.ai is Grelin's AI powered chart auditing and revenue intelligence engine. It reviews each chart for documentation gaps, coding risk, and compliance issues, and it surfaces undercoded encounters and missed billable services before claims are submitted. It runs on top of your existing EHR and RCM stack without replacing them.
Traditional audits and CDI tools sample a fraction of charts and act after claims are filed. Chart.ai reviews every chart before submission, catching documentation, coding, and compliance risk upstream, and surfacing revenue you already earned but never captured.
Chart.ai powers a family of specialty-tuned applications, including Wound.ai, Pain.ai, DME.ai, E/M.ai, and Behavioral.ai. Each one is built for the exact documentation standards, modifiers, and payer logic that decide reimbursement in its modality.
Chart.ai is built for provider organizations, hospital systems, and specialty groups that want to prevent denials and capture earned revenue upstream, along with the RCM and billing teams that support them.
No. Chart.ai runs on top of your existing EHR and RCM stack. It adds the upstream visibility your team never had without a system replacement or workflow disruption.
