Cellarian

What Cellarian does

Cellarian, Inc. is a privately held Clinical Decision Support Software company that sells a proprietary, rules-based documentation platform — branded as the "Cellarian Engine" (internal name "Vision") — to diagnostic laboratories and adjacent healthcare providers. The platform generates patient-specific, payer-aligned, provider-attested medical necessity documentation and prior authorization narratives for toxicology, molecular, PGX, respiratory pathogen, UTI, STI, women's health, and wound testing, integrating directly with customer LIMS, EHR, LIS, RCM, and middleware systems. The company explicitly differentiates its product from generative AI, positioning the engine as a continuously updated rules platform built by physicians, compliance specialists, and revenue cycle experts to produce audit-defensible documentation without hallucination risk; documentation has been reviewed for legal compliance by McDonald Hopkins (Jane Pine Wood) and used in Medicare TPE and CERT audits without pushback.

The product is composed of two core modules (Medical Necessity Documentation and Prior Authorization Documentation) plus the Opioid Risk Assessment and Stratification Worksheet as a lead-generation/adjunct resource and a referenced CellarianRx product line. Strategic alliances with Validity Diagnostics (sample-integrity/subversion detection for toxicology) and Shadowbox (HIPAA-compliant EHR/billing/payer-portal connectivity) extend Cellarian into a broader revenue-cycle ecosystem. The company is headquartered in Houston, Texas with an executive team of four (Founder/CEO Dr. Michael Sprintz, President & COO Michael C. Lu, CTO Ian Williamson, CMO Cecilie Korst) and reports operating across 39-40 US states with 200,000+ cumulative reports, 148,000+ medical necessity reports, 52,000+ prior authorizations, and an 80-90% client-reported first-pass prior authorization success rate.

Cellarian generates revenue through quote-based SaaS platform subscriptions with multi-year enterprise contracts sold via a sales-led, demo-driven motion (Calendly scheduling and direct sales outreach), supplemented by professional services for revenue recovery and appeals. Pricing is not publicly disclosed; the customer base of approximately 20 visible logos is concentrated in mid-market diagnostic labs, RCM partners (Lighthouse, Lab Revenue Navigator), pain management practices, and substance use treatment providers. The company has raised approximately $2.765M across two 2016-2017 rounds with no subsequent disclosed capital raises, and the cap table is not public.

Core offering

Cellarian provides a SaaS platform built around a proprietary, rules-based "Cellarian Engine" that automatically generates patient-specific, payer-aligned, provider-attested medical necessity documentation and prior authorizations for diagnostic laboratories. The platform interfaces with customer LIMS, EHR, LIS, RCM, and middleware systems to apply payer-specific documentation rules upstream in the revenue cycle, aiming to prevent denials, clawbacks, and prior authorization rework before claims are submitted.

Product overview

Cellarian is a single unified SaaS platform — built around a proprietary "Cellarian Engine" rules-based documentation engine (also internally called "Vision") — that automates clinical documentation upstream in the laboratory revenue cycle. The platform is composed of two tightly integrated core modules, Medical Necessity Documentation and Prior Authorization Documentation, which together generate patient-specific, payer-aligned, provider-attested documentation for toxicology, molecular PCR, respiratory pathogen, UTI, STI, women's health, and wound testing. Around these core modules sit supporting offerings such as the Opioid Risk Assessment and Stratification Worksheet (a downloadable COT risk-assessment resource) and the CellarianRx product line, and the platform is extended through technical partnerships such as the Cellarian + Shadowbox integration (for EHR/billing/payer-portal connectivity) and the Cellarian + Validity Diagnostics alliance (for toxicology sample-integrity/subversion detection). Cellarian interfaces with customer LIMS, EHR, LIS, RCM, and middleware systems; positions itself explicitly as "not AI" but as a rules-driven automation platform battle-tested against thousands of real lab claims.

Products and services

• Cellarian Engine (Cellarian Platform) The proprietary documentation engine that generates patient-specific, payer-aligned, provider-attested medical necessity documentation for diagnostic laboratories. Built over years by physicians, compliance specialists, and revenue cycle experts, it is continuously refined to meet changing payer requirements and is positioned as a rules-based automation platform that produces audit-defensible documentation without hallucinated content.
• Medical Necessity Documentation Module that automatically interfaces with LIMS, EHR, or middleware platforms, pulls structured and unstructured clinical data, applies payer-specific medical necessity criteria, and generates patient-specific justification text for toxicology and molecular PCR testing. Produces unique provider summaries with individualized diagnoses, medications, risk levels, days of abstinence, and treatment/monitoring needs.
• Prior Authorization Documentation Module that identifies when prior authorization is required, applies payer-specific documentation rules, and generates patient-specific medical necessity justification prepared for physician review and signature. Supports toxicology, respiratory pathogen, UTI, STI, women's health, and wound testing. The rules engine updates documentation logic to reflect evolving payer criteria without manual team intervention.

Broad incumbents

• FinThrive: End-to-end revenue cycle management platform with prior authorization, eligibility, and denials management for health systems and ambulatory providers. Competes for the same documentation-driven revenue protection wallet share as Cellarian.
• R1 RCM: Large-scale revenue cycle management provider focused on hospital and health-system customers. Overlaps with Cellarian's denials and documentation-driven revenue protection use cases, though it is service-heavy rather than rules-engine SaaS.
• M*Modal (3M Health Information Systems): Speech-to-text and computer-assisted clinical documentation used by hospitals and large physician groups. Adjacent to Cellarian's clinical documentation automation but oriented to broader physician reporting rather than payer-aligned lab justification.
• Experian Health: Healthcare revenue cycle management suite including eligibility verification, claims management, and prior authorization. Competes for the same lab and health-system budget as Cellarian, though it is not lab-specialized.
• CoverMyMeds (McKesson): Industry-leading prior authorization automation platform for medications, now extending into clinical and payer workflows. Overlaps with Cellarian's prior authorization automation and payer-rule engine but at a much broader therapeutic and channel footprint.
• Waystar: Cloud-based revenue cycle management platform that automates prior authorization, claims management, and denials for hospitals and labs. Addresses the same documentation/denial pain points as Cellarian but at a much larger, broader portfolio scale.

Emerging players

• Olive AI: Healthcare automation platform historically focused on revenue cycle workflows including prior authorization and eligibility. Competes in the same payer-rule automation category as Cellarian, though it has been undergoing strategic retrenchment.
• AKASA: AI-driven prior authorization and revenue cycle automation for health systems. Tackles the same payer-rule and documentation bottleneck Cellarian addresses, with greater scale ambitions and a more generalist AI orientation.
• Phreesia: Patient intake, clinical workflow, and prior authorization automation platform for ambulatory providers and health systems. Addresses adjacent documentation and workflow gaps that touch the same payer-submission lifecycle as Cellarian.

Direct peers

• Infinx Healthcare: Provides prior authorization, eligibility, and revenue cycle automation for diagnostic laboratories, radiology groups, and specialty practices. Closely overlaps Cellarian's prior authorization and payer-rule automation value proposition for labs and ambulatory providers.
