Chain of custody
for medical coding
Cierta ties each supported code to source documentation, routes it through human review, and seals the trail in a tamper-evident record. Defensible only when the evidence, approval, and chain of custody are present.

Forensics has chain of custody. Finance has the audit trail.
Risk-adjustment coding has had neither — until Cierta.
A code you can't defend is a liability
Risk-adjustment and HCC coding face growing audit scrutiny. When a finding can't be traced to the record, it becomes exposure — not value. Most tools return a score; few can show their work.
Audit pressure is rising
RADV and payment-integrity reviews increasingly demand documentation support for every adjustment. "The model said so" is not a defense.
Black boxes don't hold up
A confidence number without an evidence trail can't be reviewed, explained, or stood behind in front of an auditor.
Manual review doesn't scale
Defensible review by hand is slow and inconsistent. Teams are forced to choose between coverage and rigor.
Evidence first, by design
Cierta turns a chart into reviewable, traceable findings — with a person in the loop at the decisions that matter.
Ingest
Charts enter a controlled pipeline; real-PHI client activation stays gated until agreements and approval are complete.
Analyze
The platform extracts conditions and candidate codes, citing the exact source pages it relied on.
Evidence-link
Each finding is tied to documentation and screened for MEAT-style support before it's surfaced.
Review & trail
Coders confirm or reject; every action is written to a tamper-evident audit trail.
Built to prove what's true
Designed around defensibility — not just a number, but the reasoning and record behind it.
Evidence-linked findings
Every finding references the source page and provider attribution it came from, so reviewers can verify it directly.
MEAT-aware screening
Findings are screened for Monitoring, Evaluation, Assessment, and Treatment support before they reach a coder.
Human-in-the-loop
Cierta supports coders — it doesn't replace them. Submissions stay behind explicit human approval.
Tamper-evident audit
Actions are recorded to a hash-chained log designed to make the review history verifiable after the fact.
Audit-defense framing
The workflow is oriented toward standing behind coding decisions — not toward maximizing capture.
Explainable exports
Outputs carry their supporting evidence and provenance, so findings travel with the reasoning behind them.
One mark for evidence-backed support
When a finding clears its evidence gates and a coder confirms it, Cierta seals the record: tamper-evident, hash-chained, and verifiable later. It separates "the model is confident" from "here is the proof, and it has not changed."
- Bound to the source documentation it was drawn from
- Signed off by a named human reviewer
- Hash-chained, so any later change is detectable
Scoring vs. chain of custody
Everyone else returns a score. Cierta returns a sealed evidentiary record.
Black-box scoring
- Returns a code and a confidence number
- No traceable link to the record
- Hard to review, explain, or appeal
- Optimized for capture volume
- History is opaque after the fact
Cierta Evidence-first
- Every finding cites its source documentation
- MEAT-style support screened before surfacing
- Reviewable, explainable, evidence-backed
- Oriented toward audit defense
- Tamper-evident, verifiable history
For the teams who have to be right
Health plans
Strengthen risk-adjustment integrity with findings you can trace and defend in audit.
Provider groups, MSOs & ACOs
Bring rigor and consistency to chart review without sacrificing throughput.
Compliance teams
Move from black-box scores to a reviewable, evidence-backed record of every decision.
