Quill Bills is an AI-native medical billing agency that helps hospitals, clinics, and private practices streamline their revenue cycle management while significantly reducing operational costs. Founded in 2023 and backed by Y Combinator, the company leverages artificial intelligence combined with decades of billing expertise to automate complex medical billing workflows and maximize reimbursement for healthcare providers.
Healthcare providers in the United States face substantial financial pressures from medical billing operations. Traditional billing services charge providers between 2% and 10% of total revenue, creating a significant drain on practice profitability. Beyond these direct costs, healthcare providers lose substantial revenue through claim denials—up to 30% of claim revenue is denied by health insurance companies annually, with many denials going unaddressed due to the resource-intensive nature of manual follow-up processes.
Quill Bills addresses these challenges by building AI-native tools that automate medical billing workflows at scale. The platform combines machine learning algorithms with human expertise to process claims more efficiently than traditional manual billing approaches. By automating routine tasks and enabling human billers to focus on complex cases, Quill Bills achieves higher throughput and better outcomes than conventional billing agencies.

The company provides four integrated, modular services that healthcare providers can use individually or in combination. The AI-native revenue cycle management platform automatically builds accurate claims from electronic health record data, orders, and clinical documentation, reducing denials not filed (DNFB) and accelerating cash flow. The claim scrubbing service continuously scans payer policies to identify potential denials before claim submission, eliminating the need for manual spreadsheet-based rule management. AI voice agents handle payer communications 24/7, including eligibility verification, claim status checks, prior authorization requests, and appeal filing. For providers seeking comprehensive support, Quill Bills offers full-service medical billing with denial management, payment posting, patient statements, collections workflows, and customized reporting.

The platform ingests EHR data including orders, clinical notes, procedures, and medications to assemble fully documented claims while flagging documentation gaps in real time. This approach improves chart quality and reduces rework downstream. The system provides real-time quality checks that identify documentation deficiencies before coding begins, supporting DRG assignment, present-on-admission indicators, and clinical documentation improvement initiatives. Automatic charge capture and reconciliation detects missed charges and late entries across service lines with explainable feedback to clinicians.

Quill Bills employs policy-aware edits that automatically ingest payer bulletins, local coverage determinations, national coverage determinations, and medical policies. The system detects diagnosis and procedure misalignments, bundling conflicts, frequency limits, and authorization issues before claim submission. Root-cause analytics provide denial heatmaps highlighting patterns by payer, specialty, CPT code, DRG, or facility location, enabling providers to fix underlying processes rather than simply reacting to individual denials.
