Charta Health announced a $55 million Series B led by Insight Partners on November 10 as it launched an expanded suite for health insurers. The company is bringing the same AI chart-review engine to providers preparing bills and insurers checking the medical documentation behind them.
The San Francisco company's provider software checks clinical records for coding and documentation problems before a claim is submitted. Staff review its findings inside their electronic health record system. Charta names American Family Care and Grow Therapy among its customers.
Charta for Payers initially targets Medicare Advantage and Affordable Care Act Marketplace plans. It searches for documented diagnoses missing from codes and flags coded conditions that the record does not support. Chief executive Justin Liu says consistent checks for insurers and providers can reduce disputes over payment.
The insurer launch follows Charta's June 9 announcement of an integration with athenahealth's marketplace, which made its chart-review tools available to that vendor's medical practices. Charta plans to use the new financing for AI development and to extend its provider offering into more specialties.
The round is 2.5 times the $22 million Series A Charta announced on July 22, 2025, led by Bain Capital Ventures. Bain returned for the Series B alongside Madrona, South Park Commons and QuantumLight. Charta says the new financing brings total funding to $85 million.
