The Challenge

Healthcare organizations face critical coding challenges that impact revenue and compliance

What causes denials and lost revenue in outpatient coding?

Outpatient denials and lost revenue come from three sources: undercoding that leaves earned reimbursement uncaptured, overcoding that triggers audits and repayment, and manual review that only covers 5–10% of charts. Because most charts are never audited before billing, errors reach the payer and surface as denials, delays, and compliance exposure.

Lost Revenue from Undercoding

Services under-documented or billed at lower levels create significant revenue leakage. Missed add-on codes and incomplete documentation leave money on the table.

Compliance Risks from Overcoding

Overbilling can trigger audits, force repayment, and create compliance risk. Without proper review, coding errors can lead to serious compliance issues.

Operational Inefficiencies

Manual reviews are time-consuming and inconsistent. Most organizations only audit 5-10% of charts, delaying revenue cycles and missing critical errors.

AI Solution

AI-Powered Chart Review

Transform your coding workflow with intelligent automation that scales

How does AI pre-bill coding review reduce denials?

AI audits 100% of charts before submission, comparing each claim to documentation and payer rules. It catches undercoded services and missed add-on codes, flags overcoding and LCD/NCD mismatches, and routes corrections back to the EMR. Cleaner claims go out the first time, so denials drop and reimbursement becomes more predictable—without adding coders.

Capture Missed Revenue

Analyze 100% of charts to identify undercoded services, missed add-on codes, and documentation gaps that impact reimbursement.

Reduce Compliance Risk

Flag overcoding, documentation mismatches, and coverage-policy mismatches, such as local or national coverage determinations (LCD/NCD), before claims go out.

Scale Coding Capacity

Increase audit coverage without adding headcount. AI handles the volume while your team focuses on complex cases.

How It Works

A simple three-step process to transform your coding workflow

How do you implement AI pre-bill coding audits?

Implementation takes three steps. An engineer configures the AI to your coding requirements and payer rules. Every chart is then reviewed in real time before billing, catching errors and optimization opportunities. Finally, automated feedback flows back to your EMR, streamlining corrections and steadily improving documentation quality—typically live within four to six weeks.

Arkangel AI vs. manual coding audits

How AI pre-bill review compares with manual CPT/ICD-10 audits on coverage, speed, and denials.

Is AI coding review better than manual audits?

Manual coding audits review only 5–10% of charts, usually after billing, so undercoding and overcoding slip through and return as denials. AI audits 100% of charts before submission, applies current payer and LCD/NCD rules consistently, and pushes corrections to your EMR—cutting denials and capturing revenue without adding coding staff.
