Medical billing outsourcing to grow $33Bn by 2035: MRF
NEW YORK, UNITED STATES — The global medical billing outsourcing market is set to nearly triple — from $11.76 billion in 2025 to $33.89 billion by 2035, at a 10.35% compound annual growth rate (CAGR), according to a recent market report from Market Research Future.
A 30,000-coder United States shortage, a $51 billion Medicare error rate, and mounting regulatory complexity are pushing providers to outsource billing functions at an accelerating pace.
Medicare error rate fuels outsourcing market
Medicare’s improper payment rate hit 7.46% in 2024, generating approximately $51.1 billion in incorrect claims — and U.S. hospitals already spend more than $115 billion annually on revenue cycle management.
Yet 30,000 certified coding positions remain unfilled across the U.S., and coder turnover at hospital billing departments runs at 22%.
“Coding errors accounting for the majority of improper Medicare payments” are driving provider organizations to seek external billing partners, according to the Market Research Future (MRFR) report.
Hospital billing departments absorbed a 14% salary increase for coders between 2022 and 2024 — while still losing one in five coding staff annually.
The transition from ICD-10-CM to ICD-11 expands the coding set from approximately 72,000 to more than 80,000 codes. Federal compliance mandates under the No Surprises Act and price transparency requirements are adding further administrative load that in-house billing teams are structurally underprepared to absorb.
AI accelerates revenue cycle outsourcing growth
Artificial intelligence is reshaping the economics of medical billing outsourcing rather than displacing it. AI platforms now reach 96% accuracy for ICD and CPT code assignment, and first-pass claim acceptance has improved from 82% to 94% at organizations with AI-assisted billing infrastructure.
“Natural language processing reduces claim denials by 30 to 40%,” the MRFR report found — with vendors reporting “37% reductions in claim denial rates” and “25-day improvements in days-in-accounts-receivable” as AI-augmented workflows replace manual claim review.
By 2030, 40% of medical claims are projected to be processed by AI without human intervention — accelerating cost reduction while expanding the market for oversight and exception-handling services.
North America holds 45.72% of the global market, with the U.S. accounting for 82.5% of regional revenue. Asia-Pacific is the fastest-growing region at an 11.92% CAGR, driven by India’s 150,000-plus certified coders holding 34.6% of regional share — the offshore workforce backbone enabling the sector’s global scale.
The healthcare outsourcing sector — with medical billing at its core — is one of the most direct expressions of how offshore staffing addresses structural gaps in the U.S. healthcare system. As coding complexity rises and AI creates new demand for trained oversight staff, the case for outsourced billing operations strengthens on both the cost and compliance dimensions.
