Buyer's guide
The best AI medical billing software depends on the job.
There is no single best tool. The first question is not which AI. It is whether you have a billing team to run it.
From there the job splits six ways. A done-for-you billing service, an autonomous billing platform, a denials and appeals specialist, a coding engine, an all-in-one system of record, or enterprise infrastructure.
Here is the honest landscape, grouped by buyer job, based on publicly available product information.
At a glance.
| Product | Best for |
|---|---|
| Altair | Practices and groups with no billing team of their own. |
| Candid Health | High-volume digital-health groups wanting touchless claims. |
| Cofactor AI | Hospitals appealing complex clinical denials. |
| Fathom | Health systems automating high-volume coding. |
| athenahealth | Practices that want one all-in-one platform. |

The average cost to rework a denied claim is $47.77 for Medicare Advantage and $63.76 for commercial payers.
The landscape, by what you need.
Grouped by the job to be done, not by who pays us. The first divide is who does the work: software someone has to run, or a service that runs the billing for you. The second is intelligence: does it just automate generic tasks, or does it learn your payers and turn that into prevention?
Done-for-you billing services
The work happens outside the practice. No billing work for your front desk. CureMD's managed billing team and CareCloud's outsourced revenue cycle, further down, are the legacy version of this model.
Altair
Done-for-you billing, eligibility to payment, on the systems you already use. Real-time eligibility, prior authorization, medical necessity, payer-specific scrubbing, submission, claim tracking, remittance, patient statements, and payment posting. Denials worked on arrival, with payer-specific appeals. Learns each payer's policies and behavior, and turns live denials into prevention. Financial forecasting and per-payer transparency, so you see what each payer will pay, not just what it already paid. Our in-house billers work the exceptions, and no billing work lands on your front desk. Does not assign codes or touch charge capture. Checks the codes on the claim against each payer's policies before submission.
Best for: Practices and groups with no billing team of their own.

Autonomous medical coding
Front-of-cycle coding automation. Complementary to billing tools, not a replacement for denial and appeal work.
Fathom
Autonomous medical coding at scale: deep learning assigns ICD, CPT, and E&M codes from documentation with high automation rates. Coding-only, not full billing.

Choosing software, answered.
What is the best AI medical billing software?
It depends on what you are optimizing for. If there is no billing team, the job is a done-for-you service. Altair runs the whole cycle, eligibility to payment, on the systems you already use. Our billers work the exceptions. For a single all-in-one system of record, established platforms like athenahealth lead. For front-end coding, Fathom and CodaMetrix lead, and for enterprise infrastructure, Waystar, Optum, and Experian Health dominate.
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 did you choose these?
By the job to be done, using publicly available product information. Vendors are grouped into done-for-you billing services, autonomous billing platforms, denial and appeal specialists, coding engines, all-in-one suites, and enterprise incumbents. That way you can match the vendor to the problem instead of comparing across categories.
What should I look for in AI billing software?
Start with who does the work when a claim comes back. Software queues the denial for someone to work. A service works it and closes it. Then look at whether claims get checked against each payer's actual policies before submission. Whether appeals are payer-specific. Whether it learns your payers over time. And whether it runs on the systems you already use instead of forcing a switch.
Which is best for fighting denials?
Altair. Denials worked on arrival, not queued for someone to get to. Learns each payer's policies and behavior, scrubs every claim against that payer before submission, and drafts payer-specific appeals. When a denial needs a person, one of our billers works it. What it learns turns into prevention on the next claim.
Does Altair assign codes?
No. Coding stays where it is today, and charge capture does not move. Altair takes the codes on the claim and checks them against each payer's policies before submission. That boundary keeps the clinical record yours and the billing ours.
Is the AI medical billing market consolidating?
Yes. In 2025, New Mountain Capital combined Thoughtful AI, SmarterDx, and Access Healthcare into Smarter Technologies, and in 2024 R1 RCM was taken private by TowerBrook and Clayton, Dubilier and Rice in an 8.9 billion dollar deal. Expect more standalone AI billing tools to be acquired or merged, so weigh vendor longevity when you pick.
Is AI medical billing HIPAA compliant?
It should be. Altair is HIPAA compliant, and you can review our security posture and controls in detail at our Trust Center.
