1. PDF upload
The biller uploads the encounter PDF. Nebla extracts the embedded text (no OCR) using pdfplumber and PyMuPDF.
How it works
How Nebla Billing works
Our first product. From the clinical record PDF to the billing guide, in minutes.
2. Anonymization
Before any AI call, personal data is replaced with stable aliases. No sensitive data ever reaches the model.
3. AI extraction
Claude Sonnet 4.5 identifies procedures, medications, supplies and events. Each item is linked to its folio and source phrase.
4. Validation & deduplication
A 14-stage pipeline with support validation, ER conflict resolution, observation-room rules and EPS rules. Items without evidence are flagged for review.
5. CUPS and tariff mapping
Each item is mapped to CUPS, ISS 2000 and supplies from your contracted portfolio. EPS rates are applied per active contract.
6. Biller review
The biller sees the guide with each item, its provenance and its confidence. They approve, edit or reject. Approved items go into the final invoice.
