Cellarian Inc.

Cellarian provides software that generates patient-specific medical necessity documentation for diagnostic laboratories, supporting prior authorizations, records requests, denials, and audits. Its system is designed to address documentation gaps before claims are submitted, without changing provider workflows or adding documentation work for lab staff. Documents reflect the provider's clinical assessment and are aligned with payer requirements. The company specializes in toxicology and molecular testing workflows, serving physician-owned and clinical reference labs, hospital labs and health systems, substance use treatment providers, and pain management practices. Cellarian is based in Houston and supports labs and revenue cycle management partners across the United States.
