Forus vs Infinitus Systems (2026)
Two attacks on the same obstacle: getting a prescribed medication into a patient's hands. Forus, formerly Tandem, sits at the point of prescribing and automates the paperwork. It generates and submits prior authorizations, drafts appeals, verifies benefits, routes to a pharmacy and finds affordability programs, free to providers and patients. Infinitus Systems automates the phone calls the paperwork cannot avoid, calling payers and pharmacy benefit managers and returning results as structured data, and now handles patient support and member calls for manufacturers and payors. A prescribing practice looks at Forus. A manufacturer, patient support hub or payor looks at Infinitus. They complement more than they compete.
- Free to providers and patients, with the whole path from prior authorization to pharmacy routing and affordability help in one flow.
- It acts rather than recommends, and a language model checks form answers against the patient's record before submission.
- All protected health information under a business associate agreement, and SOC 2 Type 2 stated.
- The payer and pharmacy benefit manager call automated end to end, with copilots that work the menu and the hold and hand staff a live representative.
- Patient support and member services calls as well, including copay support and adherence check ins in English and Spanish.
- Runs on Google Cloud in the United States, with Lens to review agent led and human led calls.

Voice AI agent platform for the calls that stand between a patient and a prescribed treatment. Its agents call payers and pharmacy benefit managers to verify benefits and eligibility and follow up on prior authorizations, appeals and claim status, call provider offices to collect missing enrollment information, and return the results as structured data to the workflow that asked; copilots work the phone menu and the hold, then hand a staff member a live representative.

Questions buyers ask
How do Forus and Infinitus Systems work with the EHR?

With Infinitus Systems, the product page says the agents and copilots can be launched from within Epic, Cerner, athenahealth and Salesforce, and call results are returned as structured data to the provider, payer, hub, specialty pharmacy and manufacturer workflows that asked for them rather than left as a transcript.
