Unbundling the Portal: How Cadara & Waystar Are Fixing Post-Acute Billing

NEW YORK, NY – November 05, 2026 — In the razor-thin margin environment of post-acute healthcare, the difference between a facility's financial survival and insolvency often comes down to a few keystrokes. For years, the sector has bled revenue not necessarily because of poor patient care, but due to the sheer administrative friction of getting paid. Today, a newly announced partnership between specialized billing platform Cadara and payments giant Waystar signals a structural shift in how these facilities might finally plug the leak.

The launch of Cadara Exchange™—an integration that embeds Waystar's AI-powered revenue cycle management (RCM) directly into Cadara's cloud-based software—is more than a standard tech integration. It is a forensic response to a market pushed to the brink by staffing shortages, aggressive Medicare Advantage denial tactics, and the compounding inefficiencies of fragmented software.

For the uninitiated, post-acute care—spanning skilled nursing facilities, home health, and inpatient rehabilitation—operates under uniquely complex reimbursement frameworks. Unlike acute care hospitals, which have long benefited from enterprise-grade financial technology, post-acute operators have historically been relegated to disjointed point solutions. By bringing Waystar's massive clearinghouse infrastructure directly into the Cadara ecosystem, the partnership is attempting to unbundle the portal and give burned-out billing teams a single source of truth.

Combating Denial Creep in a Complex Payer Landscape

To understand the "why" behind this integration, one must look at the macro forces squeezing post-acute operators. Medicare Advantage (MA) plans now cover more than half of all eligible Medicare beneficiaries, bringing with them a labyrinth of prior authorization requirements and stringent medical necessity documentation.

This complexity has birthed a phenomenon known as "denial creep." Across the broader healthcare landscape, approximately 15 percent of the over 10 billion claims submitted annually are initially denied, costing providers nearly $20 billion in rework. In post-acute settings, where documentation requirements are often subjective and highly scrutinized, a delayed or denied claim can paralyze cash flow.

"Post-acute organizations are being asked to improve financial performance while navigating increasing complexity and limited resources," noted Marina Aslanyan, Chief Executive Officer of Cadara. "Our partnership with Waystar creates a more efficient revenue experience that gives teams better visibility, more time to focus on what matters, and greater confidence in managing revenue."

Waystar's Claim Manager boasts an impressive average first-pass clean claim rate of over 98.5 percent. It achieves this through an AI-enabled rules engine supported by 2.5 million continuously updated edits and over 5,000 payer connections. By embedding this capability directly into Cadara RLM (Revenue Lifecycle Management), the system acts as a proactive net. Instead of submitting a claim and waiting weeks for a denial, the software flags missing data or coding errors before the claim ever leaves the facility.

This predictive capability is critical. As one healthcare revenue cycle consultant noted, "You cannot staff your way out of modern denial trends. If you are relying on human eyes to catch a changing payer rule across fifty different commercial plans, you have already lost the margin on that patient."

The Hidden Cost of Portal-Hopping

Beyond the hard costs of denied claims lies the insidious drain of administrative bloat. The American Hospital Association recently highlighted that labor constitutes roughly 60 percent of hospital expenses, a metric that rings equally true in post-acute settings. The U.S. healthcare system spends an estimated $440 billion annually on administrative costs, much of it tied to the manual labor of revenue collection.

Historically, a post-acute billing specialist's day has been defined by the "swivel-chair" workflow. They log into their core Electronic Health Record (EHR) or billing system, export a batch of claims, log into a separate clearinghouse portal to upload them, wait for a response file, download it, and manually reconcile the data back into the original system. This portal-hopping is a recipe for data degradation, delayed remittance posting, and staff burnout.

Cadara Exchange effectively collapses this workflow. By connecting claims and payments in one unified interface, the integration eliminates the need for manual downloads and disparate logins. The automated monitoring of payment and reconciliation workflows directly targets the metric that CFOs care about most: days in accounts receivable (AR).

When staff are freed from the mundane mechanics of file transfers, they can be redeployed to high-value tasks, such as pursuing complex denial recoveries or optimizing front-end patient financial clearance. In an era where specialized billing talent is scarce and expensive, this operational leverage is a significant competitive advantage.

Big Tech Meets Niche Care: A Strategic Rebrand

The timing of this partnership also shines a light on Cadara's broader strategic pivot. Formerly known as National Care Systems, the company boasts more than 30 years of experience serving over 1,700 post-acute organizations. The rebranding to Cadara represents a deliberate move away from the legacy image of a traditional software vendor and toward a modern, interoperable technology partner.

This strategic repositioning aligns perfectly with the current consolidation trend in the RCM market. Health systems and post-acute operators alike are actively seeking to reduce their vendor footprint. They want comprehensive suites, not a patchwork of point solutions. By partnering with a behemoth like Waystar—which processes over $2.4 trillion in gross claims annually and spans roughly 60 percent of U.S. patients—Cadara instantly elevates its technological payload without having to build a clearinghouse from scratch.

For Waystar, the partnership represents a calculated expansion into a specialized sub-sector. While enterprise vendors often struggle to adapt their generic platforms to the nuanced workflows of post-acute care, strategic API integrations allow them to capture transaction volume while relying on niche partners to handle the user interface and sector-specific logic.

"Post-acute providers need connected payments technology that keeps pace with the complexity of their revenue cycle," said Matt Hawkins, Chief Executive Officer of Waystar. "By connecting Cadara RLM with Waystar's platform, we're bringing proven scale, payer intelligence, and automation into post-acute workflows — helping revenue teams get paid faster, more accurately, and more efficiently, so they can focus on improving financial performance."

Furthermore, the broader industry context cannot be ignored. Following the catastrophic ransomware attacks on major clearinghouses earlier in the decade, which crippled billing operations nationwide, providers have become acutely aware of network stability. Many organizations are now actively seeking robust, secure alternatives or establishing redundant connections. Waystar's enterprise-grade platform, combined with Cadara's localized expertise, presents a compelling safe harbor for post-acute operators looking to de-risk their financial operations.

The Cadara Exchange is available immediately for existing Cadara RLM customers. As the post-acute sector continues to navigate the turbulent waters of modern healthcare economics, the success of this integration will likely serve as a bellwether. It will test whether bringing Wall Street-grade financial automation to the frontlines of community care can truly reverse the tide of administrative waste.
