Nothing about your systems changes. What changes is who does the billing.
Over 80% of appealed denials are overturned.
Appeals work when they get written and sent. Crosby is a fast way to file them. Altair files them too, works the denials behind them, and learns each payer so fewer ever reach the appeal stage. One of our billers owns whatever the AI cannot close.

Altair vs Crosby Health, answered.
Does Altair replace Crosby Health?
They overlap on appeals. Crosby drafts and files clinical denial appeals. Altair runs the whole cycle, eligibility to payment, on the systems you already use. Appeals are one step inside that. Crosby is built for hospitals and health systems. Altair is built for practices with no billing team of their own. That is a difference in fit, not in quality.
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.
How is Altair different from Crosby Health?
Crosby is focused on drafting and submitting clinical appeals. Altair runs the whole cycle, eligibility to payment, on the systems you already use. Every denial teaches it how that payer behaves, and that becomes a pre-submission check. When a claim comes back, one of our billers works it. There is no billing work for your front desk.
Does Altair learn each payer?
Yes. Every denial Altair works teaches it a new edge case for your payers. That learning becomes a pre-submission check on the next claim. The same denial stops coming back. None of it lands on your front desk.
What financial visibility does Altair add that Crosby does not?
Altair gives you the forward view that appeals tools do not. You see what each payer will pay, not just what it already paid. Forecast by payer, probability of payment on each claim, per-payer reimbursement against expected rates, underpayments and why.
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 run. No migration, and no billing work for your front desk.
