Charta Health Secures $55M Series B to Unify AI-Based Medical Chart Review for Providers and Payers

Charta Health announced a $55 million Series B funding round led by Insight Partners, with participation from existing investors including Madrona Venture Group, Bain Capital Ventures, South Park Commons, and QuantumLight. The capital will accelerate research and development of Charta’s autonomous AI platform and support the official launches of two new offerings: Charta for Providers and Charta for Payers. Both products run on a single AI engine designed to deliver a unified standard of chart accuracy for the entire healthcare claim lifecycle. This milestone positions Charta as one of the few AI companies delivering dedicated solutions for both provider organizations and health plans.

Charta Health’s mission centers on improving billing accuracy before a claim is submitted. The company argues that current practices rely on parallel tools and disparate standards, which often lead to coding gaps, denials, and costly appeals. By providing a shared “ground truth” from a single AI system, Charta aims to reduce the cycle of denials and appeals that can drain billions from patient care budgets. CEO and co-founder Justin Liu described Charta as an effort to unlock critical data trapped in clinical documents, turning chart review into a deterministic, pre-submission process rather than a guessing game after the fact. The platform is engineered to mimic the workflows of expert coders and auditors. It highlights missing codes supported by the chart and removes those not adequately substantiated by documentation. This approach is intended to yield claims that are more likely to withstand payer scrutiny, thereby lowering denial and clawback risk for providers while offering payers cleaner data to support accuracy and compliance. In the past year, Charta has demonstrated revenue growth by a factor of ten and has completed three funding rounds in under two years as investor demand has kept pace with rapid expansion. Insight Partners’ Jeff Horing, a Co-founder and MD at the firm, commented that raising the underlying chart to match payer and provider expectations before submission is key to reducing waste across the system. He noted that Charta’s combination of AI with specialized, customer-driven coding expertise serves both sides of the market and expressed enthusiasm about supporting the team as it scales.

Charta’s leadership team includes Chief Executive Officer Justin Liu and Chief Technology Officer Scott Morris, both formerly of Rockset. The duo, who previously earned Certified Professional Coder credentials and conducted extensive interviews with healthcare leaders, now require their engineering and growth teams to obtain medical coding certifications as well. This emphasis on domain expertise underscores the company’s commitment to reliability and accuracy in high-stakes healthcare billing. The funding coincides with the launch of Charta for Payers, a new suite of AI-powered products developed in collaboration with one of the nation’s largest health insurers. Charta for Payers is designed to improve accuracy and operational efficiency across diagnosis coding and quality improvement for government-funded programs and private plans alike. The offering reflects regulators’ increasing focus on reducing waste, fraud, and abuse in the healthcare system. Charta for Providers represents the expansion of the company’s provider-focused initiative. With Series B backing, Charta plans to broaden its coverage to additional specialties and scale its provider-facing workflows. The platform’s provider module reviews every chart prior to claim submission, cross-referencing coding guidelines, payer requirements, and a given organization’s internal clinical protocols. Findings are surfaced within the electronic health record to support clinician review and approval. The intended result is a reduction in denials and a lower risk of clawbacks, enabling providers to submit claims that are substantially “built to hold up.” Notable customers include a range of major healthcare enterprises such as American Family Care, Grow Therapy, and Pediatric Associates Family of Companies. Grow Therapy’s leadership has highlighted Charta’s ability to scale chart review to support expanded access to mental health care, allowing clinicians to focus more on patient care while the system handles documentation at scale.

Charta Health positions itself as an automation-driven platform that reads clinical documentation the way a skilled coder would, flagging gaps and validating support for each code. By aligning payer and provider perspectives on the underlying chart, Charta aims to shrink the pre-submission ambiguity that often leads to disputes later in the payment workflow. The company’s approach is framed as a path to redirect billions of dollars back into patient care by eliminating the costly cycle of denials and appeals.
