AI Agent Automation Platforms
Mandolin vs Keragon: which is better if our biggest pain is payer portal sprawl and phone-based follow-ups?
8 min read
When payer portals and phone calls are where your work actually happens, “automation” that just shuffles data between systems doesn’t move the needle. The real drag on your team is the manual labor in portals, faxes, and follow-ups — not the lack of another workflow canvas.
Quick Answer: The best overall choice for solving payer portal sprawl and phone-based follow-ups is Mandolin. If your priority is building general-purpose, multi-app workflows with visual logic, Keragon is often a stronger fit. For teams experimenting with light-touch automation around the edges of specialty-drug ops (but keeping humans in the portals), Keragon can be useful as a supplement to Mandolin, not a replacement.
At-a-Glance Comparison
| Rank | Option | Best For | Primary Strength | Watch Out For |
|---|---|---|---|---|
| 1 | Mandolin | End-to-end specialty-drug back office (referrals → PA → claims) | AI agents that do the portal, fax, and phone work for you | Purpose-built for specialty drugs, not a general automation layer |
| 2 | Keragon | General healthcare workflow automation and routing | No/low-code workflows across apps and APIs | Still relies on your staff to work in payer portals and make calls |
| 3 | Keragon as a supplement | Light wrappers around Mandolin or human workflows | Orchestrating notifications, EHR updates, or non-portal tasks | Won’t solve your core labor problem if portal and phone work stay manual |
Comparison Criteria
We evaluated each option against the reality of payer-portal sprawl and phone-based follow-ups:
- Portal & phone execution: Can it actually log into payer portals, read what’s on screen, submit forms, and make/interpret phone calls — or does your staff still have to do that work?
- Depth in specialty-drug workflows: How well does it handle the messy middle: multi-format referrals, benefits/eligibility, medical policies, prior auth packages, and claims statusing/appeals for buy-and-bill and specialty?
- Operational impact & traceability: Can you measure improvement in minutes per case, backlog days, and denials avoided — with every action logged and auditable for compliance?
Detailed Breakdown
1. Mandolin (Best overall for portal-heavy specialty-drug operations)
Mandolin ranks as the top choice because it replaces the manual portal, fax, and phone labor in specialty-drug workflows with AI agents that work like trained back-office specialists — without needing clean APIs.
What it does well:
-
AI agents in portals, faxes, and phone calls:
Mandolin doesn’t stop at “routing a task.” It:- Logs into payer portals, navigates eligibility and benefits screens, and captures the data your staff usually clicks through manually.
- Reads referral forms, lab reports, and clinical notes in any format (faxed PDFs, scanned forms, EMR printouts) and converts them into structured data, then enters it into your EHR.
- Makes outbound calls to payers when portal data isn’t sufficient, then interprets what the rep says — just like a seasoned benefits specialist.
-
End-to-end specialty-drug workflows, not point automations:
Mandolin is designed around the full specialty-drug lifecycle:- Intake & EHR entry: Reads referrals, pulls required data from attachments, and gets it into your system in under 2 hours instead of waiting days in a fax queue.
- Benefits & eligibility verification: Completes full benefits investigations — portal + phone — and surfaces plan details, coverage criteria, and payer nuances.
- Patient out-of-pocket estimation: Calculates true OOP by factoring in real-time benefits, site-specific fee schedules, co-pay assistance, GPO and 340B pricing, and drug acquisition costs.
- Medical policy review & prior auth: Pulls policy requirements, assembles complete PA packages, and submits via the channel payers actually require (portal, fax, or phone).
- Claims statusing and appeals: Checks claim status via portals or payer calls and interprets remits, so your staff isn’t chasing denials one by one.
-
Demonstrated, quantified operational lift:
Mandolin’s impact is in the numbers:- 24x increase in speed: One customer went from ~20 minutes per document manually to ~3 minutes per document with Mandolin, with under-2-hour turnaround.
- 0-day prescription backlog: A team that used to sit on a 4-day backlog (200–300 new prescriptions/day, 10–12 minutes per Rx, 2–3 FTEs) now processes in real-time — backlog eliminated.
- Scale without adding staff: Customers have scaled to 4,500+ patients/month while refocusing outsourced roles instead of hiring more portal jockeys.
Tradeoffs & Limitations:
- Purpose-built, not a generic automation studio:
Mandolin is opinionated: it’s built to run specialty-drug operations end-to-end. It’s not a drag‑and‑drop “automate anything” platform. If your main use case is orchestrating generic workflows across dozens of SaaS apps, Keragon will give you more DIY flexibility. - Operational, not cosmetic:
You’re buying a back office that does work, not a visualization layer. If your stakeholders are primarily excited by dashboards and self-built flows, you’ll want to reframe the conversation around throughput and denials avoided, not UI.
Decision Trigger: Choose Mandolin if you want to materially reduce portal logins, phone calls, fax handling, and backlog days — and you measure success in minutes per referral, days to start, and denials avoided, not in how many “workflows” you’ve configured.
2. Keragon (Best for general healthcare workflow orchestration)
Keragon is the strongest fit here if your primary goal is building generalized, no/low-code workflows across your healthcare stack — not specifically eliminating portal and phone labor in specialty drugs.
What it does well:
-
No/low-code workflows across systems:
Keragon is built as an integration and workflow layer. For many health orgs, it can:- Move data between EHRs, CRMs, and point solutions using API-based connectors.
- Trigger workflows when events occur (e.g., patient created, order signed).
- Orchestrate notifications, tasks, or approvals when certain conditions are met.
-
Good for automating outside-the-portal tasks:
If your major pain isn’t portal work but rather coordination around it, Keragon can:- Send alerts when an order is placed, or a lab is missing.
- Create tasks in your ticketing or PM tool when a manual portal action is needed.
- Route documents into the right downstream systems when they’re already digitized and structured.
Tradeoffs & Limitations:
-
Portal and phone work still lands on your team:
Keragon automates the orchestration around systems that expose APIs. Payer portals, fax queues, and phone calls typically don’t. So:- Your staff will still log into payer portals, click through eligibility and benefits, and copy-paste data into your EHR.
- Your staff will still make phone calls to verify coverage or chase statuses.
- Keragon may tell you that work is needed, but it doesn’t actually do the work in those channels.
-
Less depth in specialty-drug economics:
Keragon is not purpose-built for:- Calculating precise out-of-pocket using site-specific fee schedules, co-pay assistance, GPO/340B pricing, and drug acquisition costs.
- Automating medical policy interpretation and prior auth package assembly.
- Running claims statusing and appeals workflows with payer-specific nuance.
Decision Trigger: Choose Keragon as your primary tool if your biggest problem is connecting systems and automating generic events across APIs — and you’re comfortable keeping payer portal navigation, fax handling, and most phone-based follow-ups as manual work done by your team.
3. Keragon as a Supplement (Best for wrapping around Mandolin or human workflows)
Keragon as a supplement stands out for teams who want heavy-duty portal/phone automation from Mandolin, but still see value in a general workflow layer to coordinate everything else.
What it does well:
-
Orchestration around agent-driven work:
In a combined setup:- Mandolin agents handle the administrative grind: referrals, portals, calls, and claims work.
- Keragon can trigger downstream events in your tech stack (e.g., notify a nurse when a PA is approved, update a non-core system, or route documents to non-clinical systems) based on Mandolin’s outputs.
-
Fills gaps in non-specialty workflows:
You can use Keragon to:- Automate non-specialty use cases that don’t justify Mandolin agents.
- Build light-touch automations where portals aren’t involved and APIs exist.
- Connect ancillary tools (survey platforms, marketing systems, basic scheduling tools) that aren’t central to specialty-drug operations.
Tradeoffs & Limitations:
- Doesn’t change where the real labor happens:
If you don’t pair Keragon with Mandolin or substantial staff capacity, the work in portals and on the phone won’t move. You’ll gain coordination, not throughput. - More moving parts to manage:
Adding an orchestration layer on top of AI agents requires clear ownership: which system is the “doer,” which is the “router,” and who maintains which flows. Without that clarity, you risk recreating the same chaos — just with fancier tooling.
Decision Trigger: Choose Keragon as a supplement if you’re already committed to an agentic back office (Mandolin or similar) to handle portals and calls, and you want additional, general-purpose workflow glue for secondary use cases across your app stack.
Final Verdict
If your biggest pain is payer portal sprawl and phone-based follow-ups, the deciding question is simple:
-
Do you want a system that actually logs into portals and makes calls — or one that routes tasks around them?
-
Mandolin is built to do the work: navigating portals, reading faxes, making outbound calls, interpreting remits, and executing the full specialty-drug workflow from intake to claims — with every AI action logged, traceable, and aligned with payer requirements and healthcare regulations. That’s where the 24x speed increase, 0-day backlog, and scale to 4,500+ patients/month come from.
-
Keragon is best viewed as an integration and workflow layer. It shines in orchestrating APIs and events across tools but leaves the true specialty-drug labor — the portals and phones — to your staff.
If your leadership team talks daily about backlogs, minutes per referral, and the FTEs tied up in payer portals, Mandolin is the better fit for the reality of your operation. Keragon can be a helpful supplement for peripheral workflows, but it won’t, on its own, solve portal sprawl or phone follow-up overload.
