Works with everything you already run.
Altair runs on top of every EHR, practice-management system, and clearinghouse on the market, including yours. No rip-and-replace, and no billing work for your front desk.
Runs the whole cycle: eligibility and benefits, prior authorization, medical necessity and documentation, payer-specific claim scrubbing, submission, claim tracking, remittance, denials, payer-specific appeals, financial forecasting and underpayment detection, patient statements and balances, and payment posting and reconciliation.
Nothing about your systems changes. What changes is who does the billing.
Over 80% of appealed denials are overturned.
A strong appeal recovers the claim. Cofactor drafts one for your team to review and send. Altair scrubs every claim against each payer's policies first. Denials that still land are worked on arrival, and the appeal goes out. One of our billers takes the exceptions.

Altair vs Cofactor AI, answered.
Does Altair replace Cofactor AI?
They overlap on appeals, but they are built for different buyers. Cofactor drafts appeals for complex hospital denials, with a human reviewing before sending. Altair is built for practices with no billing team of their own. Runs the whole cycle, eligibility to payment. That covers eligibility, prior authorization, scrubbing, submission, remittance, denials, appeals, statements, and payment posting. When a claim comes back, one of our billers works it.
How is Altair different from Cofactor AI?
The difference is fit. Cofactor is a focused appeals model for hospitals. Altair is built for practices with no billing team of their own. Runs the whole cycle, eligibility to payment, on the systems you already use. Learns each payer, so what one denial teaches becomes a pre-submission check on the next claim. There is no billing work for your front desk. When a claim comes back, one of our billers works it.
We do not have a billing team. Who actually does the work?
That is what Altair is built for. Altair works the claims. Our in-house billers handle the exceptions. There is no billing operation for you to staff or manage.
Does Altair prevent denials, or just appeal them?
Both. Altair scrubs every claim against each payer's policies before submission. Denials that still land are worked on arrival, and the appeal goes out. Every worked denial becomes a new pre-submission check, so the same mistake does not come back. One of our billers handles the cases that need a person.
What financial visibility does Altair add that Cofactor does not?
Cofactor predicts appeal outcomes. Altair gives you the forward view. You see what each payer will pay, not just what it already paid. Collections forecast by payer, probability of payment on each claim, per-payer reimbursement against expected rates, and underpayments with the reason.
Is Altair HIPAA compliant?
Yes. Altair is HIPAA compliant. Review our security posture and controls in detail at our Trust Center.
How long does it take to get started?
Days. Altair connects to the systems you already use, so going live is a matter of days, not an engineer-led onboarding. There is no billing work for your front desk, on day one or after.
