Bottom line
- Pick Aspirion if you're a hospital with denials, MVA, workers' comp, or VA claims you can't work in-house and you'd rather pay only from what gets recovered.
- Pick Crosby Health if clinical denials are piling up unworked and you want appeals generated and submitted automatically while paying only from what gets recovered.
Aspirion
Complex claims and denials recovery for hospitals
- Founded
- 2012
- HQ
- Columbus, GA
- Stage
- PE-owned (Linden Capital Partners)
- Raised
- n/a
What it does
- Clinical and technical denials appeals with attorney support
- Motor vehicle accident and workers' compensation claims
- VA, TRICARE, and out-of-state Medicaid billing
- Underpayment and zero-balance review
- Aged AR resolution
- AI-assisted appeal generation and claim prioritization
Where it's strong
- Named 2025 Best in KLAS for denials management, its second consecutive year, which is rare third-party validation in this segment.
- In-house attorneys and clinicians handle payer disputes most internal RCM teams cannot staff, and it serves over 140 clients including many of the largest US health systems.
- Contingency-style pricing ties fees to actual recoveries, keeping downside risk low for the provider.
What buyers should weigh
- It is a recovery service that works claims after the fact; it will not fix the upstream registration or coding problems causing the denials.
- The company has absorbed several acquisitions (Boost Healthcare, FIRM, Continuum), so ask which team and toolset will actually work your inventory.
- Contingency fees on high-dollar complex claims add up; model the effective rate against building internal capacity.
Crosby Health
AI-generated clinical appeals for denied claims
- Founded
- 2022
- HQ
- New York, NY
- Stage
- Seed
- Raised
- $2.2M+
What it does
- Generates clinical appeal letters for denied claims with AI
- Apollo clinical LLM reads up to 300 pages of documentation
- Finds medical necessity evidence inside clinical notes
- Submits appeals through one unified payer submission channel
- Tracks appeal status and payer decisions with notifications
- Supports medical coding review and chart auditing
Where it's strong
- Attacks a problem most providers simply abandon: appealing every denial, including small balances that are uneconomical to work manually.
- Unified payer submission removes the portal-and-fax maze that makes appeals so labor intensive.
- Early users report appealing denials 300% faster than manual processes.
What buyers should weigh
- Very early company: roughly 15 employees, about $3M raised, and only one publicly named customer.
- Appeals-only focus means it recovers lost revenue but does nothing to prevent denials upstream.
- No publicly documented EHR integrations, so verify how clinical documentation actually gets into the platform.
