U.S. Medical Billing Outsourcing Market

U.S. Medical Billing Outsourcing Market Summary

The U.S. medical billing outsourcing market size was estimated at USD 6.95 billion in 2025 and is projected to reach USD 17.69 billion by 2033, growing at a CAGR of 12.56% from 2026 to 2033. Increasing challenges faced by healthcare providers in managing a large volume of claims and reimbursements, resulting in significant revenue losses, are attributed to the rising demand for medical billing outsourcing services in the U.S.

Moreover, amplifying patient load and the need to address the growing records and bills burden medical practitioners. Hospitals are outsourcing the medical billing process to counter such a situation, thus anticipating market growth. Moreover, hospitals outsource medical billing to companies that have end-to-end knowledge of the Affordable Medical Care Act, Medicaid, and other healthcare and insurance programs. In addition, the healthcare industry is observing an increase in the outsourcing of billing activities by physicians and hospitals due to mandatory implementation of the intricate ICD-10 coding structure, growing care costs, and regulatory pressure to implement electronic medical records to sustain compensation levels. Medical services are facing complex challenges in billing and precise payment, which is anticipated to drive the demand for innovative RCM solutions. The availability of advanced innovative RCM solutions offered by renowned third-party service providers can help healthcare organizations leverage the economic value and efficacy of these RCM solutions while simultaneously focusing on improving patient care.

Furthermore, hassle-free claims settlement processes featuring accounts receivable management and claims management and the availability of professional coders acquainted with the latest medical codes are the primary reasons practices outsource their billing services. However, high threats of data breaches associated with medical billing are expected to hinder market growth during the forecast period. For instance, according to the 2024 Healthcare Data Breach Report published in January 2025 by the Department of Health and Human Services (HHS) Office for Civil Rights (OCR), more than 500 data breach records were reported in 2024.

Furthermore, billing service providers are increasingly deploying advanced technologies such as artificial intelligence (AI), robotic process automation, and predictive analytics to transform medical billing operations. AI-driven coding engines automatically extract and assign codes from clinical documentation, reducing human error and improving first-pass claim acceptance rates.

Automation streamlines repetitive tasks, including charge entry, eligibility verification, and claims submission, accelerating billing cycles. Advanced analytics identify denial patterns, payer-specific issues, and revenue leakage risks in real time. These capabilities enhance accuracy, reduce reimbursement timelines, and improve compliance. For instance, in June 2025, Collectly launched Billie, the first AI voice agent for patient billing and RCM, available 24/7 via chat, email, text, and voice. It resolves 85% of inquiries instantly without staff assistance, boosts cash flow by 32%, reduces collection costs by 20-30%, and eliminates missed calls, utilizing real-time EHR/insurance data for personalized bill explanations and payments.
