Revenue cycle software that gets you paid.
G3 Flow checks coverage, sends clean claims, posts what insurance pays, works denials and bills patients for their share. Run it yourself or hand any part of it to our team. Either way, nothing changes in a live system until your team approves it.

Before the claim went out, G3 Flow checked it against payer and CMS rules. A visit billed with an injection on the same day needs modifier 25, so the claim was fixed before it was sent.

Aetna’s remittance arrived with the payment. Of $240.00 billed, $75.00 is the contractual adjustment, $33.00 is the patient’s coinsurance, and Aetna paid $132.00.

The routine work runs on its own. Decisions wait for your team.
Eligibility checks, claim edits, status inquiries, posting and statements run every day without anyone starting them. Anything that would change a live system stops and shows a person exactly what will change.
- See it before it runs
- Posting payments, sending claims or changing a record shows the items, the count and the total first. Nothing is sent until someone confirms.
- Undo everyday decisions
- A deposit match, an acknowledged alert or a cancelled task can be undone for 15 minutes by the person who made it.
- One queue for the work people do
- Deposit matches, lab order changes and anything else that needs a person wait in the Work queue, the most overdue first.

Protected on every account.
G3 Flow handles protected health information under a business associate agreement. These safeguards are on for every organization, from its first account.
How G3 Flow protects patient data-
Two-step verification
Every account signs in with a code from an authenticator app, with ten single-use recovery codes as a backup.
-
A business associate agreement
Accepted when you create your organization, versioned and kept on file.
-
Encrypted, with every view logged
Patient data is encrypted at rest with AES-256-GCM, and each time someone views it is recorded.
-
Full or masked
Each person sees patient data in full or masked. Masked accounts can’t export, download or print it.
-
Single sign-on
OpenID Connect with Entra ID, Okta or Google, and SCIM to add and remove people automatically.
-
Sessions that end
Idle sessions end on their own, and exporting patient data asks for a fresh two-step code.
Starting takes minutes. Going live follows a plan.
