How Rectangle Health automates insurance reimbursements with embedded payments
With Adyen’s embedded payments suite integrated into the PayerSync platform, healthcare practices complete a simple, digital onboarding experience in minutes.
For over 30 years, Rectangle Health has helped thousands of healthcare providers simplify patient payments and manage the revenue cycle.
Today, that experience and innovation extends one step further—transforming how practices receive insurance reimbursements through PayerSync™.
With Adyen’s embedded payments suite integrated into the PayerSync platform, healthcare practices complete a simple, digital onboarding experience in minutes.
Once setup is complete, payer payments are routed directly and securely into provider bank accounts and into the Patient Management System (PMS), accompanied by digitized explanation of payments (EOPs).
This streamlines one of the most painful parts of healthcare operations: processing and reconciling insurance reimbursements.
From paper piles to instant payments
Insurance (payer) reimbursements are still stuck in the past.
ACH, virtual cards, and paper checks require hours of manual reconciliation, slow down payments, and tie up working capital.
Rectangle Health created PayerSync to solve this challenge and selected Adyen for embedded finance to enable a completely digital, automated reimbursement process.
‘We carefully selected Adyen as our embedded finance partner,” said Matt Bernier, VP of Payer Solutions at Rectangle Health.. “We’re confident in their ability to provide a trusted and secure platform with a seamless digital onboarding experience.”
With Adyen’s embedded finance platform, PayerSync enables practices to:
Automatically ingest virtual card payments from payers
Instantly reconcile payments with claims and patient records
Speed up reimbursements through Adyen’s licensed global banking infrastructure
Identify remaining patient balances earlier to accelerate follow-up
“A fully customizable setup, and strong collaboration during implementation reinforces our confidence in Adyen,” Bernier continued.
Great Lakes Dental Partners cuts reimbursement time by ~80%
The results speak for themselves. Reimbursement processes that once took weeks now take days. The elimination of manually keying payments and claim details frees up hours for staff and unlocks faster access to funds.
To manage insurance reimbursements across their 28 locations, Great Lakes Dental Partners implemented PayerSync.
“Payments that used to take two weeks, now arrive in two or three days,” said Donna Ramadan, VP of Revenue Cycle & Compliance at Great Lakes Dental Partners. “Our providers have noticed the difference.”
