FAQs
Payment integrity is one of the most complex and high-impact areas in healthcare. Health plans are under constant pressure to improve claims accuracy, reduce overpayments, and prevent costly errors. These FAQs break down how payment integrity works, what Penstock does differently, and how deeper audits can lead to better financial and operational outcomes.
Payment integrity refers to the process of ensuring healthcare claims are accurate, compliant, and properly paid. It involves identifying errors like overpayments, incorrect coding, or billing inconsistencies—and correcting them through audits and analysis.
Post-pay audits happen after claims are paid and focus on identifying missed errors and recovering dollars. Pre-pay audits occur before payment to prevent mistakes upfront. Penstock focuses on post-pay audits as a way to uncover patterns and improve future payment accuracy.
Penstock offers several payment integrity services, including:
- Data mining for overpayment detection
- Chart review for clinical validation
- Itemized bill review for line-level accuracy
- Upcoding prevention programs
- Regulatory support like NY HCRA audits
These services work together to improve accuracy and reduce waste.
Chart review involves analyzing medical records to confirm that billed services are supported by clinical documentation. This ensures coding accuracy and compliance with payer policies.
Penstock uses a human-led, tech-enabled approach, where experienced auditors—not algorithms—make final decisions. This results in more accurate, explainable, and defensible findings.
Payment integrity audits can uncover:
- Incorrect medical coding
- Unsupported billing (upcoding)
- Duplicate charges
- Policy or contract misalignment
- Systemic billing patterns across providers
By identifying overpayments and preventing repeat errors, payment integrity programs reduce waste, improve efficiency, and ensure healthcare dollars are spent appropriately—ultimately lowering costs for plans and members.
Healthcare claims are complex and require clinical, coding, and regulatory judgment. Human auditors can interpret context and nuance that automated systems often miss, leading to more accurate and defensible outcomes.
Penstock helps health plans improve payment accuracy by conducting deep, post-payment audits that uncover overpayments and billing errors. Their work turns audit findings into insights that help prevent future issues and reduce long-term costs.
Post-pay audits are often the last opportunity to catch costly errors and recover lost revenue. They also provide insight into systemic billing patterns, helping health plans strengthen their processes and prevent repeat issues.
Data mining analyzes large volumes of claims data to detect patterns, anomalies, and billing trends that may indicate overpayments. This helps uncover issues that traditional reviews often miss.
An itemized bill review examines every line of a healthcare bill to identify errors, inconsistencies, or unnecessary charges. This detailed approach helps catch both large and small overpayments.
Penstock turns audit findings into actionable insights. By identifying root causes and recurring patterns, they help health plans improve pre-payment controls and reduce future errors.
Penstock primarily partners with health insurance plans—national, regional, and local—to improve claims accuracy and reduce unnecessary healthcare spend.
Penstock emphasizes defensible, evidence-backed findings that hold up during audits and appeals. Their work is designed to be transparent, traceable, and supported by clinical and coding expertise.
