Prior authorization and medical necessity documentation — built for diagnostic laboratories.
see how it works.
Cellarian generates patient-specific, payer-aligned documentation before claims are submitted — supporting prior authorization, pre-payment review, and medical necessity requirements.
The result: fewer denials, reduced audit exposure, lower administrative burden, and more predictable reimbursement.
The Problem:
Diagnostic laboratories lose significant revenue — not because testing lacks clinical merit, but because documentation fails to meet payer-specific standards.
Ordering providers are focused on care delivery — not on writing documentation that anticipates payer interpretation.
The consequences:
Prior authorization delays
Medical necessity denials
Rework after submission
Appeals and clawbacks
Increased audit scrutiny
Most revenue cycle teams are left fixing documentation after payment is at risk.
Payers don’t pay for drug testing
They pay for documented medical necessity.
Providers don’t have time to document
And they never will - they have so little time with each patient.
the result: lost revenue
Denied claims, prior authorization rejections, recoupments, CMS audits, and FWA risks.
