Altair vs SmarterDx, answered.
Does Altair replace SmarterDx?
They cover different ground. SmarterDx is a clinical revenue-integrity tool for hospital inpatient denials, working from the chart. Altair is done-for-you billing, eligibility to payment, on the systems you already use. Where SmarterDx drafts clinical appeals for staff to send, one of our billers owns what comes back. The honest answer is fit, not quality. Altair is built for independent practices with no billing team of their own.
How is Altair different from SmarterDx?
SmarterDx reads the clinical chart to build appeals for inpatient clinical denials, which staff send. Altair reads the payer. Runs the whole cycle: eligibility, prior authorization, scrubbing each submitted code against the payer's policies, submission, and remittance. Patient statements and payment posting are covered as well. Denials are worked on arrival, and one of our billers handles the exceptions. Altair learns each payer's policies and behavior along the way, on every claim, not just inpatient clinical ones. No billing work comes back to your front desk.
Is Altair only for clinical denials?
No. Denials of every kind get worked: eligibility, authorization, bundling, medical necessity, and more, on every claim. Prevention comes first. Every submitted code is checked against the payer's policies before the claim goes out. Prior authorization is mapped to payer criteria.
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 assign or suggest codes?
No, and that boundary is deliberate. Coding and charge capture stay exactly where they are today. Altair takes the code as submitted and checks it against the payer's policies before the claim goes out. That is scrubbing, and it is where denials get prevented.
What financial visibility does Altair add that SmarterDx does not?
Altair gives you the forward view that clinical revenue-integrity tools do not. Forecasts collections by payer. Scores each claim's probability of payment. Shows per-payer reimbursement against expected rates, and flags underpayments and why. You see what each payer will pay, not just what it already paid.
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. Going live takes days, not a long rollout, and there is no billing work for your front desk.
