Charge governance for health systems
Every charge. Every change. Provably governed.
Vellum governs changes to your chargemaster across every facility. Each change starts as a request, goes to the right reviewers for their role and facility, and ends with evidence you can verify instead of simply trusting.
Built for: CFOs and finance · Revenue integrity · Chargemaster (CDM) managers · Compliance and audit · IT and security

The problem
Charge changes carry real risk, and they're hard to prove.
A health system's charge description master (CDM, or chargemaster) changes all the time: new services, updated descriptions, inactivated items. Each change touches revenue, compliance and downstream billing, often at many facilities at once. When changes aren't governed, wrong charges can reach claims, audit questions go unanswered for lack of evidence, and published price files drift from the approved record.
Many facilities, one standard
Corporate changes have to reach the right sites without overwriting legitimate local differences.
Unclear ownership
Outside a governed path, it's hard to show who requested, reviewed and approved each change, and when.
Field-level exposure
Not every reviewer should be able to edit every field at every step, and the rule needs to be enforced, not just displayed.
Audits that rest on trust
A change history that can be quietly edited can't prove anything to an auditor.
Uncontrolled handoffs
Approved changes still have to reach the EHR and billing systems in a scoped, controlled way.
Little visibility
Leaders need to see what's in flight, what's stuck and what's waiting on whom.
What Vellum is
One governed path for every charge change.
Vellum is a tenant-isolated, audit-first governance platform for controlled charge and master-data changes. Every change follows the same three-part flow.
Request
Add, update or inactivate a charge. Each request carries a field-by-field before and after.
Approval
Ordered review steps by role. Reviewers see only what their role and facility allow, on desktop or mobile.
Evidence
Every event is hash-chained. Proof exports as JSON, CSV or PDF for auditors.
Why Vellum is different
Governance first, evidence built in.
The change is the governed record
Each change is a request with a field-level diff, a workflow step and an owner, not a loose edit to a charge.
Verify, don't trust
A tamper-evident hash chain and exportable proof make the history something you can check.
Made for multi-facility systems
Corporate-to-facility propagation, local override preservation and single-site inactivation are part of the core model.
Enforced, not just displayed
Field locks, facility scope and tenant isolation are enforced on the server and in the database.
Scoped by role and facility
Reviewers see only the requests their role and facility allow.
Controlled handoff
Files and integrations leave only through governed, scoped channels, including Vellum's integration layer.
