Smart Features That Reduce Claim Denials

Built-in quality checks and intelligent analysis to maximize first-pass claim acceptance.

🎯

Confidence Scoring

Every code comes with a 0–100% confidence score. High-confidence codes are accepted quickly; lower ones are flagged for human review.

🛡️

Denial Risk Detection

Scans each code set for denial triggers — mismatched pairs, missing specificity, NCCI edit conflicts — before you submit.

Clean Claim Score

A composite 0–100 score predicting first-pass acceptance. Aim for 85+ before submission.

💬

Rationale Explanation

Every code includes a plain-English rationale — perfect for training, audits, and building coding confidence.

📋

Multi-Diagnosis Support

Complex encounters with multiple diagnoses are handled in one pass, correctly sequenced per ICD-10 Official Guidelines.

🔧

Modifier Suggestions

The AI recommends CPT modifiers (-25, -51, -59, -LT, -RT) based on clinical context — reducing modifier-related denials.

Frequently Asked Questions

How accurate are the generated medical codes?
Our AI achieves 90–95% accuracy for standard clinical scenarios. Every code includes a confidence score so you can prioritize review. We recommend always verifying codes with a qualified medical coder before billing submission.
What types of codes does it generate?
The tool generates ICD-10 diagnosis codes, CPT procedure codes, and HCPCS codes for equipment and supplies when applicable. Each code includes a description, confidence score, and rationale.
Is my patient data secure?
Yes. Clinical notes are sent securely over HTTPS and are never stored permanently on our servers. Data is only used to generate codes for your session and is discarded immediately after processing.
What is the Free plan limit?
The Free plan allows 2 code generations per day and up to 30 per month at no cost. No credit card is required to get started.
Can I use this for billing submission?
The generated codes are AI suggestions for reference and educational purposes. All codes must be reviewed and verified by a qualified medical coder or healthcare professional before submitting to insurance payers.
What is a Clean Claim Score?
The Clean Claim Score (0–100) reflects the completeness and accuracy of the coded claim. A higher score means fewer denial risks and a better chance of first-pass acceptance by insurance.
How do I upgrade my plan?
Click the Upgrade button in the top right of the app. You can choose from Pro ($50/mo), Plus Pro ($500/mo), or Unlimited ($1000/mo) plans. Contact support@medicalcoding.online for payment assistance.
How long does it take to generate codes?
Code generation typically takes 5–15 seconds depending on the complexity of the clinical note. The AI analyzes the entire note, identifies relevant diagnoses and procedures, and provides detailed rationale for each code selected.
Does it support E/M coding?
Yes. Our AI can suggest appropriate Evaluation and Management (E/M) CPT codes based on the documentation. It analyzes the level of history, examination, and medical decision-making complexity to recommend codes like 99213, 99214, or 99215 for office visits.

How AI-Powered Medical Coding is Revolutionizing Healthcare Documentation

Medical coding has long been one of healthcare's most critical yet time-consuming tasks. Every patient visit, procedure, and diagnosis must be translated into standardized codes for billing, insurance claims, and medical records. For years, this process has relied heavily on manual effort, deep expertise, and countless hours of work. But what if there was a faster, more accurate way?
