On October 13, Brellium announced $23 million in venture funding alongside CortexLM, a system the company says reviews patient notes for care and compliance gaps before billing. The New York-based company plans to use the money to serve more provider groups, expand into new specialties and deepen its work in the revenue cycle. Left Lane Capital and First Round Capital led the financing, with Digital Health Venture Partners participating.
CortexLM moves review before billing
Brellium describes CortexLM as a chart-auditing system that reads patient notes, checks them against each provider’s requirements and flags errors with proposed fixes before a claim goes out. The company says the process is meant to help providers address documentation problems earlier, rather than after a payer dispute, denial or repayment demand. The announcement does not disclose the system’s technical architecture, how its performance is evaluated or how providers review its proposed fixes.
“CortexLM is how we get everyone working from the same standard, so providers can prove the care was right the first time, instead of spending months untangling it after the fact,” Zach Rosen, Brellium’s co-founder and CEO, said in the release. The product launch sits alongside the funding announcement, but Brellium did not identify a named funding series or disclose a valuation.
Expansion targets cardiology, pain management and primary care
Brellium says the funding will support expansion into cardiology, pain management and primary care, as well as service for additional provider groups and work deeper in the revenue cycle. Those specialties would extend the company’s chart-review business beyond its existing customer base in behavioral health and other provider settings. The release gives no launch dates or detailed expansion schedule.
The company says it has audited 22 million patient visits and protected nearly $2 billion in provider revenue from recoupments. Those figures are company-reported totals; the release does not provide a methodology or independent assessment. Brellium also says its customer base includes more than 215,000 providers and 200 provider groups across all 50 states, naming Gentiva, Maxim Healthcare, Rula and Headspace among its customers.
Headspace’s note-review figures are a customer example
Brellium’s release points to Headspace as an example of its software in use. It says Headspace expanded its clinical quality-assurance review from 2% of therapy notes to 100% after adopting Brellium and now reports 99.2% provider compliance with documentation standards. The announcement does not explain how that compliance rate is calculated or how long the change took.
The release also says Brellium will cover the cost if the Centers for Medicare & Medicaid Services or a payer later finds a problem in a record the company’s system had cleared. It does not spell out the terms, limits or exclusions for that commitment. For providers considering the service, the scale of note review and the precise conditions of that financial promise are concrete questions alongside the software’s ability to flag documentation issues before billing.
