Attend Health vs Charta Health (2026)
Pre bill review of every encounter, rather than a sample, is the common ground. Charta runs it as a standalone review platform on large language models: it codes visits after the note closes, corrects coding in the EHR or queues problem charts for a person, cites the documentation behind each suggestion, and reads faxes, scans and handwritten notes as well as structured fields. Attend runs its audit beside its own scribe, so what the audit learns goes back into how notes are drafted. The practical split is whether the practice wants to change its documentation tool. Charta reviews whatever documentation exists, from any scribe or none, and serves payers with risk adjustment and RADV support as well as providers. Attend asks the practice to adopt its scribe to get the full loop, and in return the fix for a recurring coding problem lands in the template rather than in a rework queue. Charta's marketing is part of the picture. Its product pages promise to completely and accurately code every service, while its only accuracy figure, 98 percent, belongs to payer risk adjustment projects rather than provider coding.
- Documentation and review come from one vendor, so a coding pattern found in audit is fixed in the scribe's configuration.
- Clinicians see coding suggestions with explanations while charting, before the audit runs.
- Documents how its athenaOne, Elation and Cerbo integrations read context and where notes land.
- Business associate agreement available to read before contracting, in the platform terms.
- Sits behind any scribe or none, reviewing documentation however it was produced.
- Reads handwritten notes, faxes and images as well as structured EHR data.
- Cites the supporting documentation on every coding suggestion and can queue problem charts for a person.
- Serves payers too, with retrospective and prospective risk adjustment, second pass QA and RADV audit management.

Each vendor in one paragraph
Written to be quoted whole. Each paragraph states what the AI Health Index verified about the vendor, with the caveats attached.
Attend combines an AI scribe with an audit that reviews every outpatient encounter before billing for incorrectly coded visits and documentation integrity gaps. Because Attend also writes the note, a recurring finding becomes a change to the scribe's templates and instructions, and providers see coding suggestions with explanations at the point of care. Attend connects to athenaOne, Elation and Cerbo and quotes each practice for the scribe, the audit or both.

Yes. Attend Audit reviews every encounter for incorrectly coded visits and documentation gaps before the claim goes out, and Charta reviews documentation for every encounter, coding after the note closes and correcting or queuing charts that need attention.

Can Charta work behind a scribe the practice already uses?
Charta reviews whatever documentation the practice produces, including faxes and scanned images, and says it has integrated with dozens of commercial and homegrown EHRs without naming them. Attend's audit is designed around Attend's own scribe, with findings fed back into the scribe's configuration.
