Prior authorization documentation and medical necessity justification — built specifically for diagnostic labs.

Cellarian generates patient-specific, payer-aligned documentation that supports prior authorization, pre-payment review, and medical necessity requirements before claims are submitted — reducing denials, audit exposure, and administrative burden, while increasing revenue and improving cash flow.

The Problem:

Diagnostic labs lose millions in revenue every day — not because tests aren’t clinically appropriate, but because documentation fails to meet payer-specific requirements. And your ordering providers aren’t going to work any harder to get you that documentation.

Prior authorization delays, vague medical necessity language, and inconsistent clinical justification all lead to denials, audits, and rework after the fact.

Cellarian fixes the documentation problem with “Patient & Payer Specific” automation.

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.

The Cellarian Solution:

Cellarian is a healthcare documentation automation platform that:

Generates patient-specific medical necessity justification for clinical services
No additional work for the laboratory or billing staff
Aligns documentation to payer and CMS criteria
Integrates directly into existing LIS and EHR workflows
Automatically generates detailed prior authorization medical necessity documentation for >85% first-pass approval
Allows for provider edits, comments, and sign-off on EVERY document

Documentation is created before billing, not reconstructed after denial.

And we made it simple to use.
