TriFetch vs Linear Health: Which AI Front Desk Fits Your Clinic?

If you're shopping for AI to help with referrals and prior authorizations, Linear Health is probably on your list. It's built around referral coordination, with a strong focus on clinics that run on athenahealth.

TriFetch is on the same list for many clinics. On paper, the two cover a lot of the same ground. The differences show up at the edges: who answers the phone when a patient calls in, what happens when a payer denies an auth, and how much setup it takes to connect to your EMR.

We wrote this to help you compare the two on the things that matter to a clinic's front desk. We're TriFetch, so we've stuck to what Linear publishes about itself and linked our sources at the end.

What does Linear Health do?

Linear Health builds AI for referral coordination. Its tagline is "Turn referral faxes into booked appointments." It handles inbound referrals from fax, email, web forms and phone, creates the chart, verifies eligibility and flags when a prior auth is needed. It also handles outbound referrals, from matching the patient to a specialist to following up on the consult note.

Linear sells prior authorization as a separate product, described as "AI-driven auth submissions to payer portals," with status tracking. Its voice AI calls patients in English and Spanish for outreach and scheduling, and it also offers care-gap outreach. It serves FQHCs, primary care groups, specialty practices and behavioral health organizations.

What does TriFetch do?

TriFetch's AI front-desk agent, Linda, handles the admin work between a patient's first call and their visit. She answers calls around the clock, up to 50 at once. She reads referral faxes and enters them into your EMR. Then she verifies eligibility, submits the prior authorization, tracks it and appeals the denial if there is one.

TriFetch works with mid-size to large healthcare clinics and health systems, across specialties like gastroenterology, cardiology, ENT and ophthalmology.

How do TriFetch and Linear Health compare?

Here's how the two line up on the work a clinic front desk actually does.

Linear details reflect its public website as of November 2026. See the full TriFetch comparison page for other vendors.

Who covers each step, from call to approved visit?

A referral passes through several hands before it becomes a visit the clinic gets paid for, and one prior authorization can take about 45 minutes of staff time. Here's the full path, and which tool covers each step based on what each one publishes.

Linear covers the middle of the path well. The differences are at both ends: the inbound call that starts it, and the denial that can end it. Our guide on why prior authorizations get denied goes deeper on that last step.

How do they connect to your EMR?

Linear lists established integrations with athenahealth, NextGen, eClinicalWorks and Greenway Health, and describes athenahealth as its primary focus, connected through athenahealth's official API.

TriFetch takes a different approach. Linda logs into your systems with her own credentials and works on the same screens your staff use. If your EMR runs in a browser, including NextGen, eClinicalWorks and athenahealth, she can work in it. There's no integration project and no migration.

How fast can you go live, and what does it cost?

Linear says its first workflow goes live in 4 weeks, with more complex workflows scoped separately. TriFetch goes live in one week for clinics on a browser-based EMR, usually starting with the workflow that costs you the most, like a referral fax backlog or a prior auth queue.

Both companies publish pricing. Linear lists plans from $2,000 a month per workflow, sized to volume. TriFetch's custom plans start at $5,000 per month and are priced on the work Linda does: which workflows she runs, how much volume each one handles, and how many provider schedules are set up. Adding staff never raises your price. Every plan includes HIPAA compliance, SOC 2 certification, a signed BAA and a 30-day opt-out period. See the pricing page for details, or estimate your savings with the ROI calculator.

Smaller clinics that need just one workflow can join the waitlist for TriFetch's self-serve plan, coming in early 2027. It's built for practices with fewer providers and lower patient volume, with one standard workflow and quick self-guided setup.

For a real example: at one GI practice, Linda handles up to 100 referrals a day that used to take two full-time staff. That freed about 16 staff hours a day and returned over $200,000 a year to the clinic. Read the GI case study.

Which one should your clinic choose?

Choose TriFetch if

• You want inbound calls, referrals and auths in one agent
• You want denied auths appealed, not just tracked
• You want to go live in a week with no EMR integration
• You run several workflows and want pricing tied to work done

Linear may also fit if

• You only need help with referral coordination right now
• Another team or vendor already answers your inbound calls

Running on athenahealth, or a primary care group? Linda works in athenahealth and with primary care practices too, so TriFetch is an option either way.

When TriFetch isn't the right fit

TriFetch's custom plans are built for multi-provider clinics automating several workflows. If you're a smaller practice that only needs help with one thing, like phones or prior auths, a custom plan may be more than you need today. The self-serve plan coming in early 2027 is designed for you: one standard workflow and a quick self-guided setup. Join the waitlist on the pricing page, or email inquiry@trifetch.ai with "Self-serve waitlist" in the subject.

And if your EMR only runs as installed desktop software rather than in a browser, talk to us first so we can check how Linda would work with it.

Frequently Asked Questions

What's the difference between TriFetch and Linear Health?

Both use AI to process referrals, check eligibility, submit prior authorizations and book patients. TriFetch also answers every inbound call 24/7 and appeals denials, and it works in any browser-based EMR without an API.

Is TriFetch a Linear Health alternative?

Yes. Clinics comparing AI referral and prior auth tools often look at both. TriFetch fits when you want calls, referrals and prior auths handled by one agent, live in one week on a browser-based EMR.

Does Linear Health appeal denied prior authorizations?

Linear's public site lists prior auth submission and status tracking, but not denial appeals, as of November 2026. TriFetch submits, tracks and appeals.

Does TriFetch need an EMR integration?

No. Linda logs into your browser-based EMR with her own credentials and works on the same screens your staff use.

How much does TriFetch cost?

Custom plans start at $5,000 per month, priced on the volume of work Linda handles, not per seat. Book a demo for an exact quote. Linear Health lists pricing from $2,000 a month per workflow.

Is there an option for smaller clinics?

Yes. A self-serve plan for smaller clinics that need one workflow is coming in early 2027. You can join the waitlist on the pricing page.

The Bottom Line

Linear and TriFetch both take referral and prior auth work off your front desk. If referral coordination is the only gap and your phones are already covered, either can help. If you want one agent that answers every call, carries the referral through prior auth and appeals the denial, inside the EMR you already use, TriFetch is built for that.
