2025 Healthcare RCM Year in Review & What to Expect in 2026

December 9, 2025 | AI, CDI, IDR, Prior Authorization, Revenue Cycle Management

As 2025 comes to an end, the revenue cycle management environment continues to evolve rapidly. Hospitals and physician groups are experiencing increased payer scrutiny, more complex regulatory requirements, and a growing need for stronger front-end and mid-cycle processes. Below is a recap of the most significant trends in 2025 and a look ahead at what RCM leaders should expect in 2026.

What Shaped RCM in 2025

Denials Continued to Rise

Many hospitals reported higher denial rates throughout 2025, particularly related to coding accuracy, medical necessity, and prior authorization. Providers also noted an increase in claim errors and greater difficulty achieving clean claims. With rework costs continuing to grow, organizations placed renewed focus on prevention and cleaner documentation long before a claim is submitted.

Payer Audits Became More Aggressive

Audit frequency and severity increased across inpatient and outpatient services. Organizations saw higher dollar amounts tied to denied or disputed claims. This trend prompted many revenue cycle teams to strengthen internal compliance reviews and proactively identify documentation gaps that could trigger an audit.

IDR and Out-of-Network Recovery Remained Essential

Under the No Surprises Act, the Independent Dispute Resolution process (IDR) remains a crucial tool for resolving out-of-network underpayments. In 2025, payers challenged a significant portion of claims submitted to IDR as ineligible. Even so, many disputes continued through arbitration and resulted in improved reimbursement for providers. These results reinforced the importance of accurate eligibility review, complete documentation, and timely submission.

Operational Automation and Better Workflows Grew in Importance

While full automation remains out of reach for many health systems, providers made meaningful progress in improving manual processes. Enhanced claim scrubbing, clearer prior authorization workflows, stronger denial prevention reviews, and better documentation support helped reduce errors and stabilize cash flow. Many organizations concentrated on building more reliable, repeatable workflows to handle rising claim volumes and complex payer rules.

What to Expect in 2026

Continued Growth in Denial Prevention

Denials are unlikely to decline in 2026. Provider organizations will need a consistent focus on documentation quality, accurate code selection, authorization validation, covered services identification, and eligibility checks. Structured denial prevention programs will become a core operational requirement.

More Scrutiny of Out-of-Network Claims and IDR

Payers are expected to continue tightening their interpretation of NSA eligibility. This will create more disputes around what qualifies for IDR. Providers that maintain disciplined workflows and strong documentation packages will be in the best position to secure appropriate reimbursement.

More Demands on Prior Authorization Teams

CMS finalized several rule changes affecting prior authorization. These rules aim to streamline data sharing but may introduce new operational requirements in some markets. Providers should prepare for shifting utilization rules, new payer-specific requirements, and increased need for real-time authorization tracking.

Greater Focus on Front-End Quality

As payer requirements grow more complex, scheduling, verification, authorization, and intake processes will play a larger role in preventing downstream denials. Many hospitals will prioritize improving communication between clinical teams and revenue cycle departments to ensure complete and accurate documentation from the start.
