Attend Health vs CombineHealth (2026)
CombineHealth starts where the note ends. Its coding agent, Amy, assigns ICD-10, CPT, HCPCS, evaluation and management levels, modifiers and HCCs from finished encounter notes, attaches a rationale to each code, and sends charts below a confidence threshold the customer sets to certified coders; further agents handle eligibility, claims, payment posting, receivables and appeals. Attend starts at the visit: its scribe writes the note, and its audit reviews every encounter before billing and feeds what it finds back into the scribe. The choice turns on where the revenue problem sits. A group whose documentation is sound but whose coding and billing staff are stretched gets more automation from CombineHealth, whose evidence is concentrated in emergency medicine and anesthesia, including Brault. A practice whose coding problems start in the note itself gets the fix closer to the source with Attend. Both make claims that outrun their evidence. CombineHealth reports 97.2 percent coding accuracy while its FAQ promises 100 percent compliant and accurate outputs, and Attend reports adoption and time savings with no coding accuracy figure at all.
- Writes the note as well as reviewing the code, so documentation gaps can be fixed where they start.
- Provider facing coding suggestions arrive with explanations during charting.
- Built for outpatient clinicians, with named users in internal medicine, dermatology, endocrinology and physical therapy.
- Audio deleted once transcribed, and unused notes marked deleted after seven days.
- Amy codes ICD-10, CPT, HCPCS, E/M levels, modifiers and HCCs with a rationale and supporting documentation on each code.
- A confidence threshold the customer sets decides which charts go to certified coders.
- Mark, Adam and Rachel extend automation into eligibility, claims, payment posting, receivables and appeals.
- SOC 2 Type 2 report available on request, and no training on customer data without permission.

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 is an AI scribe paired with a coding and documentation audit for outpatient practices. The scribe drafts notes, patient instructions and visit summaries in templates built with the practice, the audit reviews every encounter before billing, and findings are fixed by changing how the scribe writes. Attend works with athenaOne, Elation and Cerbo, deletes audio once transcribed, and quotes each practice for the scribe, the audit or both.

How does each handle a code the AI is unsure about?
CombineHealth routes charts below a confidence threshold, set by the customer, to certified coders and flags uncertain codes for review.

Do Attend and CombineHealth train on customer data?
