medical coding

A wrong ICD-10 code costs $25,000 in denied claims and rework. Per error.

WhiteBox runs every clinical note through multiple AI models to find the right code. When they agree, auto-code. When they disagree, route to a certified coder with the full breakdown. Every decision auditable. Every code defensible.

the problem

What goes wrong in AI-assisted medical coding

01
Specificity errors

Clinical note says: "patient presents with chest pain, radiating to left arm, with shortness of breath." Is this R07.9 (chest pain, unspecified), I20.9 (angina pectoris, unspecified), or I21.9 (acute myocardial infarction, unspecified)?

The specificity level determines reimbursement. One model picks the generic code, another picks the specific one. WhiteBox shows the disagreement so a coder picks the correct specificity.

02
Comorbidity misses

Encounter note mentions diabetes management AND a new foot ulcer. The primary reason for visit is diabetes, but the foot ulcer is a separate billable code.

Single model codes diabetes (E11.9) and misses the ulcer (L97.529). Multiple models catch both conditions because they interpret the note differently.

03
Upcoding and downcoding risk

45-minute complex office visit with counseling. One model codes 99214 (moderate complexity), another codes 99215 (high complexity). The difference is $80 per visit.

Coding too high is fraud. Coding too low loses revenue. WhiteBox flags the disagreement so a coder confirms the correct level, protecting you both ways.

use cases

Anywhere clinical notes become codes, you need consensus

01
Inpatient coding

Auto-code discharge summaries with multi-model consensus. Flag complex cases for certified coders. Reduce coding backlog.

02
Outpatient / E&M coding

Classify office visit complexity (99211-99215) accurately. Protect against upcoding audits and downcoding revenue loss.

03
Emergency department

Code ED visits in real time from provider notes. Priority routing for high-complexity cases.

04
Surgical coding

Map operative notes to CPT codes. Flag when models disagree on primary vs secondary procedures.

05
Radiology coding

Auto-code imaging reports. Catch specificity errors before claim submission.

06
Denial prevention

Pre-check codes before submission. When models disagree on a code, review it before the payer denies it.

compliance

Built for healthcare compliance

HIPAA audit trail

Every coding decision logged with model votes, confidence scores, and final assignment. Exportable for compliance audits.

Human-in-the-loop

No code is finalized without confidence. Low-confidence codes always route to a certified coder with the complete model breakdown.

Defensible coding

When a payer audits a code, you can show: "4 AI models agreed on I21.3, OR 2 disagreed and a certified coder reviewed the case and selected the final code." That is defensible.
