Most lab revenue isn’t lost because of bad testing.

It’s lost because documentation doesn’t match payer expectations.

The documentation gap is costing labs money.

Diagnostic laboratories lose revenue every day because documentation fails to meet payer expectations — even when testing is clinically appropriate.

Payers don’t reimburse testing because it was performed.

They reimburse testing that is properly documented.

Providers don’t have time to document.

Providers are focused on patient care, not writing documentation designed for payer interpretation. They do not have the time to create detailed, patient-specific justification for every order, every payer, and every testing scenario.

That leaves laboratories stuck chasing missing documentation after claims are already at risk.

The result is familiar:

  • Denied claims

  • Prior authorization delays

  • Appeals and resubmissions

  • Payment clawbacks

  • Increased audit scrutiny

  • Unpredictable cash flow.

Most revenue cycle teams are trying to repair documentation after reimbursement problems already exist.

Cellarian addresses the problem before claims are submitted.

Payer scrutiny is increasing — and it’s accelerating.

Audit activity is rising across both government and commercial payers.

Documentation requirements are expanding.

Prior authorization is becoming standard for more test types.

What used to get paid no longer does.


And what gets paid today may be audited tomorrow.

Most solutions fix denials after they happen. Cellarian prevents them before they occur.
