CodaMetrix

What is CodaMetrix and who sells it?

CodaMetrix is a Boston company founded in 2019. It grew out of a tool built by the Massachusetts General Physician Organization billing office and was spun out of Mass General Brigham (CodaMetrix About page, Becker's Hospital Review). The CEO is Hamid Tabatabaie. A $55M Series A led by SignalFire closed in February 2023, and a $40M Series B led by Transformation Capital was announced on 12 March 2024 (Business Wire). Third-party totals range from $95M to $110M.

What does it do?

The flagship platform is CMX CARE. CMX Automate codes and bills cases "with no human intervention". CMX Amplify feeds decisions that human coders reviewed back into the model, and CMX Insights reports on automation performance, benchmarking and documentation gaps (CodaMetrix website, October 2026). Inputs include clinical notes, including those from ambient documentation, as well as registration events, surgical schedules, orders, charges and provider information. KLAS interviews named radiology, pathology, surgery and E/M, and CMX CARE now covers inpatient professional fee coding.

Epic Toolbox lists CodaMetrix, according to a third-party summary from August 2024. Secondary sources also report connections to Oracle Health, GE and Meditech. CodaMetrix's own page says only that it pulls from the EHR and ancillary systems.

What does the evidence say?

The evidence is KLAS data and vendor material.

CodaMetrix announced on 4 February 2026 that it ranked No. 1 in the inaugural 2026 Best in KLAS segment for autonomous coding. In that release, KLAS figures reported by the vendor were 93% would buy again, 93% call it part of their long-term plan and an 8.0 likelihood-to-recommend score across more than 30 health systems in 27 states. The KLAS report itself is paywalled.

KLAS's 2025 autonomous coding report, as excerpted on its public page, was more mixed. Customers "consistently report functionality gaps" and want broader specialty adoption and stronger implementations. The same page says customers praised the vendor relationship and accuracy comparable to human coders.

Vendor results are bigger. The site claims 60% fewer coding-related denials, and the 2024 Series B release claimed 60% lower coding cost, 70% fewer denials and five weeks faster time to cash. Touchless rates are disputed. Rival CombineHealth puts the market at 50% to 80% depending on specialty, while a roundup repeats a vendor figure of 96% or more. Neither figure is verified.

Is it secure and compliant?

CodaMetrix's trust center shows SOC 2 and ISO 27001:2022 and lists a 2025 Type 2 SOC report available on request (CodaMetrix trust center). HIPAA compliance appears only in secondary sources, and HITRUST is not stated. FDA clearance does not apply to billing software.

How much does CodaMetrix cost?

Pricing is by contract, reached through a meeting request. Whether it is charged per claim, per encounter or as a share of recovered revenue is not published, and that is the first question to put to the vendor.

How does it compare?

KLAS's 2025 report covered CodaMetrix, Nym and Fathom. Other names in autonomous or assisted coding include Solventum, Optum, SmarterDx, Rivet, RapidClaims and Waystar. Solventum's 360 Encompass is computer-assisted and not autonomous (CombineHealth and web comparisons).

The verdict

A revenue cycle team already evaluating autonomous coding should put CodaMetrix on the shortlist and press for the touchless rate by specialty and the name of whoever audits it. Without published accuracy data, the KLAS ranking is the only outside signal. A practice that codes in house with a handful of coders has no reason to take the meeting.
