01Human in the loop
Does Karev submit codes automatically?
No. A coder reviews and approves every claim before anything is billed. The model proposes codes with a rationale; a human always makes the final call.
Karev reads your clinical record and assigns the right CPT codes — including the charges that usually slip through — with a coder in the loop before anything is billed.
A read-only audit surfaces under-coded visits, missed add-ons, and denials worth resubmitting — each with the reasoning attached.
Between the clinical note and the paid claim, dollars leak — and most of it is never caught.
Visits get billed below the level the documentation supports. The work happened; the charge doesn’t reflect it.

Add-on codes, secondary procedures, and ancillary services never make it onto the claim — quiet revenue that’s simply forgotten.
Claims bounce on NCCI edits, missing modifiers, and documentation gaps. Staff burn hours resubmitting what should have been clean.
Coders read every chart by hand. It’s slow, expensive, and inconsistent — and it doesn’t scale as volume grows.
One specialty-agnostic backbone with a human approval gate — and PHI that never leaves your VPC.
Rationale spans tie each suggestion to the exact words in the de-identified note, mapped to CMS guidelines — so coders audit in seconds, not minutes.
Patient ██████ seen ██/██ in follow-up for type 2 diabetes, hypertension, and hyperlipidemia. A1c 8.2 — insulin titrated and metformin continued. Renal function reviewed; diet and adherence counseled. Return in three months.
Moderate MDM: three chronic conditions addressed with prescription drug management — supports an established-patient level 4 under the CMS 2021 MDM table.

PHI never leaves your VPC. The core model is self-hosted inside infrastructure you control, and records are de-identified before any non-BAA call or model training.
We measure accuracy per CPT section and never claim more than we’ve validated. Pathology was the proof of concept; we expand coverage section by section as the numbers hold.
PDFs — including scanned documents via OCR — and JSON, including FHIR R4. No deep EHR integration required; everything normalizes into one internal representation before the model sees it.
The full CPT set — E/M, anesthesia, surgery, radiology, pathology and lab, medicine, plus Category II and III — along with modifiers, NCCI bundling edits, and E/M leveling.
No. The system codes conservatively, since overbilling creates fraud exposure for you. It defaults to defensible, well-documented codes and routes anything uncertain to a human reviewer.
