Driving Smarter, Scalable DRG Review Operations for a Leading US Healthcare Payer

Read | Jul 09, 2025

AUTHOR(s)

A WNS Perspective

Key Points

  • A US healthcare payer sought to modernize its legacy DRG review operations – hampered by manual workflows and siloed systems – to address rising claims complexity, compliance pressures and persistent delays, visibility gaps and scalability issues.
  • WNS re-engineered the payer’s DRG operations by integrating intelligent automation, analytics-led quality assessment and expert-driven process re-design – creating a digital-first, human-led model primed for resilience and rapid scaling.
  • The solution delivered measurable cost reduction, faster review cycles and near-total gains in process knowledge while strengthening audit readiness and equipping the client to scale effortlessly amid regulatory change.

The Industry Landscape
Pressure to Scale DRG Reviews with Precision

For healthcare payers, ensuring the accuracy and integrity of inpatient claims is non-negotiable. DRG reviews are essential to validating provider-submitted healthcare claims, yet traditional models are increasingly strained by rising claim volumes, diverse plan types and shifting regulatory requirements.

To keep pace, payers need a smarter solution that fuses advanced automation with clinical expertise. By integrating technology and human expertise, organizations can transform their healthcare payer operations review for scalable execution, regulatory compliance and cost optimization without compromising precision.

The Challenge
Modernizing a Manual, Scattered Review Function

The client faced significant limitations in its DRG review operations. Its legacy model was built on highly manual processes and siloed tools, resulting in:

Manual data transfer

between systems, which delayed reviews and introduced errors

Scalability challenges

that made it difficult to manage volume spikes

Lack of real-time visibility

into review queues and workforce performance

Limited Quality Assurance (QA) infrastructure

that constrained audit readiness and process control

To stay ahead of rising claim complexity and regulatory demands, the client needed a modern, agile operating model that could streamline processes, enhance accuracy and support scalable, data-driven reviews.

The Solution
A Digitally Enabled, Scalable DRG Model

As a digital-led business transformation and services partner specializing in healthcare automation, WNS deployed a holistic, transformation-focused engagement designed to harmonize smart automation with expert review capabilities. Our solution emphasized:

1. Enhanced Process Design

We streamlined the DRG workflow with embedded QA checkpoints, real-time status tracking and a unified interface for clinical reviewers.

2. Integrated Quality and Capacity Management

Analytics-powered dashboards enabled dynamic capacity forecasting, transparent productivity tracking and continuous quality improvement.

3. Targeted Project Execution

A dedicated team handled backlogs and complex DRG scenarios, allowing core operations to maintain stability and focus.

4. Training and Scalability Enablement

Structured onboarding and performance-based training accelerated ramp-up and ensured the model could scale on demand.

The Outcome
Scalable Review Operations with Strategic Impact

The re-imagined DRG model delivered measurable gains in cost, speed and quality:

FAQs

1. What are the challenges healthcare payers face in DRG reviews?

Healthcare payers face challenges such as high claim volumes, manual and inconsistent review processes, limited visibility into coding accuracy, regulatory complexity, and difficulty scaling operations while maintaining audit compliance and quality.

2. How does automation enhance DRG review operations?

Automation streamlines DRG reviews by standardizing workflows, reducing manual effort, and enabling faster identification of coding discrepancies. Automated task routing and rule-based validations help improve accuracy, consistency, and turnaround times.

3. What role does analytics play in scaling DRG review operations?

Analytics enables payers to prioritize high-risk claims, identify patterns in coding errors, and continuously improve review strategies. Data-driven insights support better resource allocation and scalable operations without compromising quality.

4. How can WNS’s solution improve process knowledge and audit readiness?

WNS embeds structured workflows, documentation, and audit trails into DRG review processes. This improves institutional process knowledge, ensures consistent execution, and enhances audit readiness by providing transparency and traceability across reviews.

5. What are the measurable outcomes of modernizing DRG review operations with WNS?

Modernizing DRG review operations with WNS leads to faster turnaround times, improved coding accuracy, enhanced compliance, better scalability, and increased recovery opportunities while maintaining consistent quality standards.
