Altair vs Adonis
Adonis orchestrates broadly. Altair runs the whole cycle.
Adonis is an AI RCM orchestration platform for provider groups and health systems.
Altair is the AI billing team you never have to manage. Runs the whole cycle, eligibility to payment, on the systems you already use. When a claim comes back, one of our billers works it.
Breadth, or the whole cycle, run for you.
Adonis automates broadly across the revenue cycle for provider groups and health systems, with agentic and human-in-the-loop modes. Altair is built for practices with no billing team of their own. Runs the whole cycle, eligibility to payment, learns each payer, and works denials on arrival. Our billers work the exceptions, not yours. That makes this a question of fit, not of quality.

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.
$54,000 leaks every 90 days.
That is the revenue a typical practice loses to denials and underpayments each quarter, and most of it is recoverable. Altair is built to win it back, claim by claim, and to learn your payers as it does.

Altair vs Adonis, answered.
Does Altair replace Adonis?
It can. Both cover the revenue cycle, so this is a question of fit. Adonis orchestrates the full revenue cycle for provider groups and health systems. Altair is built for practices and groups with no billing team of their own. Runs the whole cycle, eligibility to payment, on the systems you already use. 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.
How is Altair different from Adonis?
Both automate broadly across the revenue cycle. The difference is the learning and who the leftover work lands on. Where Adonis learns patterns platform-wide on a shared model, Altair learns your practice's specific payers. Denials get worked on arrival. Our billers work the exceptions, so there is no billing work for your front desk.
Does Altair assign or suggest codes?
No. Altair does not put words in the chart. It checks the codes you submit against that payer's policies before the claim goes out, and flags anything that will not clear.
What financial visibility does Altair add over Adonis?
Altair gives you the forward view. Collections forecast by payer, probability of payment on each claim, reimbursement against expected rates, and underpayments flagged with the reason. You see what each payer will pay, not just what it already paid. Adonis surfaces RCM analytics retrospectively.
Can Altair run alongside what we already use?
Yes. Altair runs on the EHR and clearinghouse you already have. No rip-and-replace, no new system to learn, and no billing work for your front desk.
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 what you already run, so going live takes days, not a rollout program.
