Ambience Healthcare

Every module in the suite is a model at work: the ambient note, coding suggestions, clinical documentation integrity checks, after visit summaries, referral letters and the pre visit chart review. Chorus, the platform underneath, assembles chart context for each of them and writes results back to the record. There is no version of the product without the models.

The clinician reviews each draft and decides what reaches the chart. Notes arrive with suggested ICD-10 and CPT codes, and Ambience describes clinicians reviewing and confirming documentation and coding in real time before the note is uploaded to the record. The coding tools check the note against coding requirements while the patient is still in the room and keep an audit trail that revenue cycle teams can follow.

What the published material leaves out is how a reviewer is told where to look. Nothing links individual statements in the note back to the recorded conversation, nothing marks low confidence passages or codes, and no threshold is described at which the system stops and hands a decision to a person. That gap carries more weight here than for a note alone, because the same output drives codes and patient facing summaries.

The model supplier is named, and so is the method used to adapt its models. Ambience's inpatient CDI assistant, launched in September 2025, is described as built on OpenAI's GPT-5 reasoning together with Ambience's own proprietary models. Its coding model was trained with OpenAI's reinforcement fine tuning and tested on a gold panel of complex cases across several specialties, each labeled by a consensus of four or more expert clinicians; Ambience reported a 27 percent relative improvement over board certified physicians on ICD-10 coding accuracy. Chorus is described as the shared layer that supplies context, orchestration, controls and measurement to every product.

No model card, version history or update practice is published, so a customer cannot see when the model behind its notes or codes has changed.

OpenAI is the named model provider. Ambience's own announcements describe its inpatient CDI assistant as built on GPT-5 and its coding model as trained with OpenAI's reinforcement fine tuning, and the platform is available through the Microsoft Azure Marketplace. The trust center lists a subprocessor list among its resources, released on request.

What governs encounter data once it reaches OpenAI, including how long it is kept and whether it can be used for training, is not published.

Named deployments carry dated figures. Cleveland Clinic onboarded more than 4,000 ambulatory clinicians in four months; a year in, more than 4,800 clinicians had used the scribe across more than 3.5 million encounters, with 70 percent encounter level use among established users, a Net Promoter Score of 60 and 96.6 percent satisfaction, reported in an August 2026 Perspective in npj Health Systems written by Cleveland Clinic and Ambience authors. A KLAS impact study with St Luke's Health System reported a 22 percent increase in clinician face time with patients and physician burnout falling from 45 to 31 percent at three months, and KLAS also published a return on investment review and a 97.7 Spotlight score. MultiCare reports 92 percent clinician adoption after a head to head evaluation, and Ardent Health a threefold return from coding and time savings.

The npj article describes a deployment rather than testing an intervention against a comparison, and the remaining figures are customer or survey reports without a published study design.

Every workflow is designed to safeguard protected health information, in the company's description, and the trust center lists controls for data retention procedures, encryption and deletion of customer data when a customer leaves, under SOC 2 Type I and Type II audits. The terms let Ambience keep and use de identified data derived from patient information for any purpose, including marketing, unless the master services agreement says otherwise.

Whether customer encounters train or improve models, and how long encounter audio and transcripts are kept, is not published.

The trust center states Ambience's business associate status: when providing services in the United States, Ambience is classified as a business associate under HIPAA, and the law's protections apply to all patient information it accesses. The company also says it meets all HIPAA privacy and security requirements.

The privacy policy covers Ambience's websites and applications and leaves processing for provider customers to customer agreements, which may include business associate agreements, and the terms of service defer to a master services agreement. Neither the business associate agreement nor the master services agreement is public.

Ambience's trust center lists SOC 2 Type I and SOC 2 Type II, alongside GDPR and HIPAA, and offers a SOC 2 Type II report dated 2026, a 2026 penetration test report and a subprocessor list to customers who request access. The company states that it is independently audited.

The listed controls cover infrastructure security, such as unique database authentication and restricted encryption key access, organizational security, product security with regular penetration testing and control self assessments, internal procedures including tested continuity and disaster recovery plans and cyber insurance, and data handling, including deletion of customer data when a customer leaves. A compliance automation vendor has published a case study on Ambience reaching SOC 2 Type II.

Ambience holds no FDA clearance. Section 3 of the end user terms says Ambience does not provide medical advice or make diagnostic, treatment or other clinical decisions, and that the services do not replace the professional judgment of health care professionals. Section 2 limits access to health care professionals who are United States residents.

The terms, last updated 26 February 2023, describe a browser extension and a demo version that predate its coding tools, Conditions Advisor, Care Context and Chorus. Coding and documentation integrity at the point of care can shape what a clinician documents, and the company markets the platform as capturing complexity and reimbursement.

KLAS has published a Spotlight report and a return on investment review of the product, and the company reports coding results against a clinician labeled gold panel. Chorus is described as carrying controls and measurement for every workflow, and the platform covers more than 200 specialties across ambulatory, inpatient and emergency care, writing after visit summaries in the patient's language.

Performance by accent, dialect, language or care setting is not reported.

The terms of service, dated 26 February 2023 and linked from the site footer, place the risk of the output on the user. Section 3 says neither Ambience nor any content provider warrants that results will be accurate, relevant, complete or up to date, that the user alone verifies all medical information, that output may be computer generated and inaccurate, and that Ambience is not responsible for any billing, coding or claims activity. Section 11 disclaims all warranties, section 12 caps aggregate liability at the fees paid in the prior twelve months and excludes direct as well as indirect damages, and section 13 runs indemnity one way, from the clinician to Ambience, including for the clinician's provision of care.

The controls that let someone catch an error are review before signing and the coding tools' audit trail. No warranty covers the output itself, and a patient affected by a wrong note or code has no route to the vendor. The Ambience Standard puts fees at risk against the health system's outcome targets, coding accuracy among them, but neither the share at risk nor any base fee is published, so what a customer pays when a target is missed cannot be read from public material.

Two way integration covers the major hospital record systems. The Epic integration has been live since 2023, when John Muir Health launched it as a two way connection built in two weeks; Ambience joined Epic's Toolbox program in August 2025, and clinicians launch it from Haiku in outpatient, emergency and inpatient settings. Onvida Health runs chart summarization, scribing, coding and patient summaries inside Hyperspace and Haiku. On Oracle Health, a March 2024 integration with Cerner Millennium reads from and writes to Dynamic Documentation, so clinicians edit notes section by section in Cerner. athenahealth is also named.

Care Context and Chorus pull prior notes, labs, imaging, medications and problem lists into each workflow and write results back to the systems of record.

The platform is delivered as a hosted service and is available through the Microsoft Azure Marketplace. Deployment runs in weeks rather than months, the company says, with Ambience clinicians, engineers and value specialists working inside each health system under The Ambience Standard. Access is limited to clinicians based in the United States, and the trust center says HIPAA applies when Ambience serves US customers.

Where encounter data rests, by region or isolation model, is not stated.

Contracts are enterprise only, sold to large health systems, with no published price, tier, free plan or self serve route. Since 19 August 2026 Ambience's contracts follow The Ambience Standard: dedicated clinical, engineering and value attainment teams work inside each customer, and fees are put at risk against the health system's own outcome targets, with utilization, burnout, retention and coding accuracy among the measures, rather than charged by seat, token or usage.

The structure is public and the numbers are not. No base fee, share at risk, unit of charge or worked example is published, nor who measures an outcome or settles a disputed one. Ambience publishes KLAS's return on investment review on its site.

Health systems are the market, across ambulatory, inpatient and emergency care, with specialty tuned documentation for more than 200 specialties and subspecialties. Named deployments span academic medical centers and community systems, from Cleveland Clinic's 23 hospitals and 276 outpatient locations to pediatrics, oncology and gastroenterology groups, and the inpatient CDI assistant is aimed at hospitalists.

Support is English first, after visit summaries can be written in the patient's language, and access is limited to clinicians based in the United States.
