Ambience Healthcare's AI Platform Surpasses Clinician Performance by 27% in Medical Coding, Powered by New OpenAI Breakthrough
SAN FRANCISCO, CA / ACCESS Newswire / May 27, 2025 / Ambience Healthcare today announced a major advancement in ambient AI, unveiling the first AI model that outperforms board-certified physicians in ICD-10 coding accuracy.
Trained using OpenAI's Reinforcement Fine-Tuning (RFT) technology, Ambience's AI platform achieved a 27% relative improvement over physician benchmarks-reducing coding errors by approximately one-quarter and offering a powerful tool to tackle the $266 billion in annual administrative waste, including $19 billion in diagnosis coding & documentation substantiation errors.
This new model identifies precise ICD-10 codes based on patient encounters, which feed into Ambience's 'coding-aware' scribe. By leveraging these codes first, the scribe generates a fully informed note-allowing clinicians to review and confirm accurate documentation and coding in real time.
'Think of this technology as a scribe that fluently speaks both clinical language and the intricate healthcare billing rulebook from day one,' said William H. Morris, MD, MBA, Chief Medical Officer of Ambience Healthcare. 'Our platform helps clinicians finish their notes faster and ensures that revenue cycle teams receive cleaner, more accurate, and audit-ready charts.'
Ambience is live across inpatient, outpatient, and emergency settings at health systems throughout the United States, supporting over 100 medical specialties with real-time, compliant documentation. Clinicians at more than 40 organizations including UCSF Health, St. Luke's Health System, Houston Methodist, John Muir Health, and Memorial Hermann Health System leverage Ambience before, during, and after patient encounters to generate compliant documentation, alleviate burnout, and enhance care quality.
How Ambience's 'Coding-Aware' AI Scribe Works
Ambience Healthcare's platform streamlines the clinical documentation and coding process:
'We built for compliance at the core of our platform because health systems need assurance that AI technology in the workflow can stand up to audits, protect reimbursement, and support clinical documentation integrity,' said Michael Ng, CEO and Co-Founder of Ambience Healthcare. 'The stakes of getting this wrong are too high for compliance to be an afterthought.'
Validated Results with RFT Technology
To validate its AI's mastery of the 'coding rulebook,' Ambience assembled a 'gold-panel' test dataset of complex clinical cases spanning multiple medical specialties. Each encounter was meticulously labeled by a consensus of four or more expert clinicians to establish a high-quality ground truth.
'Reinforcement Fine-Tuning lets developers align powerful AI models with the precision and robustness that high-stakes domains like healthcare demand,' said Shyamal Anadkat, Head of Startup Solutions at OpenAI. 'Ambience's results show how RFT can lift the performance of AI systems in safety-critical environments'.
The Ambience model was benchmarked against 18 experienced, board-certified physicians on ICD-10 coding accuracy. The results were significant: Ambience's AI demonstrated a 27% relative improvement in coding performance compared to the expert physician baseline, suggesting the model could help eliminate up to one quarter of the coding errors even the most seasoned clinicians make.

EliseAI raises $250 million in a16z-led round to expand in healthcare
By Krystal Hu (Reuters) -Enterprise software maker EliseAI has raised $250 million in a Series E funding round to expand its automation tools for the healthcare and housing industries, the company told Reuters. The latest funding values the company at over $2.2 billion, doubling its valuation from about a year ago. Venture capital firm Andreessen Horowitz led the round, with participation from Bessemer Venture Partners and existing investors such as Sapphire Ventures. Shop Top Mortgage Rates Personalized rates in minutes A quicker path to financial freedom Your Path to Homeownership The New York-based company, which builds AI to automate customer service and operations, said it surpassed $100 million in annual recurring revenue (ARR) earlier this year. The fresh capital will be used to fuel product innovation and double its roughly 300-person team over the next year, its CEO Minna Song told Reuters in an interview, with hiring plans across offices in New York, San Francisco, Boston and Chicago. The funding highlights investor appetite for so-called vertical AI companies that build deeply integrated, industry-specific solutions rather than general-purpose models. For EliseAI, the capital provides the firepower to deepen its hold on the real estate market and scale its newer healthcare division, tackling costly administrative tasks in two of the economy's largest and most complex sectors. "We've seen a fundamental shift in the market, from talking about AI to using it to solve really costly problems," Song said in an interview. "The demand from our customers was really strong, and so we decided that now is the time to invest in scaling." EliseAI's platform is able to automate the entire resolution process by focusing on specific industries, said Alex Immerman, partner at Andreessen Horowitz. "A vertical AI like ours will go really, really deep and will take that customer request and then handle every step that's required to resolve it," he said, including coordinating with vendors, scheduling, and ensuring compliance. The company started by targeting the housing industry in 2017, and expanded its applications to healthcare since 2022, an industry it said is burdened by similar communication friction and manual processes. With generative AI technology bursting onto the scene, its software can handle more complicated customer inquiries and workflows by integrating with models like the ones from OpenAI. It serves Zillow Group and other rental managers, and touts its technology is currently used in one in eight apartments in the U.S. In healthcare, the company has been focusing on outpatient specialties, including dermatology and women's health, integrating with electronic health record systems to automate administrative work.
