Why Medical Professionals Choose Our AI Coding Tool

Coding-specific checks that a general-purpose assistant does not do.

Minutes Down to Seconds

Generate a complete ICD-10 and CPT code set in seconds, in place of the 15–30 minutes a chart takes to code by hand.

A Confidence Score on Every Code

Each suggestion carries its own score, so you can see at a glance which codes are safe to accept and which need a closer look.

Reduce Claim Denials

Built-in denial risk detection and Clean Claim Score (0–100) to maximise first-pass acceptance by insurance payers.

How Medical Coding Online Works

Three steps — no training, no setup required.

1

Enter Clinical Notes

Copy and paste patient documentation, SOAP notes, or clinical narratives directly into our secure interface.

2

AI Analysis

The model reads the diagnoses, procedures and terminology in the note and works out which codes the documentation supports.

3

Review & Export

Get ICD-10, CPT, and HCPCS codes with confidence scores, denial risk alerts, and export options.

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 — useful for training, audits, and settling disagreements about a claim.

Multi-Diagnosis Support

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

Modifier Suggestions

Recommends CPT modifiers (-25, -51, -59, -LT, -RT) from the clinical context, cutting modifier-related denials.

Frequently Asked Questions

How accurate are the generated medical codes?
Accuracy is high for standard clinical scenarios, and every code includes a confidence score so you can prioritize review. Complex or sparsely documented encounters are harder, which is why codes should always be verified by 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 10 code generations per month at no cost, with no credit card required. Image upload and PDF/CSV export are on the paid plans, which start at $19/month.
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?
Open your account from the top right of the app and choose Upgrade, or see the pricing page for current 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.
