Payment Integrity & Claims Audit Support
Every Incorrect Payment Is Lost Margin. We Fix It.
Pre-pay validation to prevent incorrect claims, post-pay audit to ensure accuracy, overpayment recovery to recoup funds, and fraud & waste control to protect revenue and compliance.
Payment Integrity is a financial control: not a compliance checkbox
Overpayment Leakage
Industry estimates place overpayment rates at 3–5% of total claims spend. For a mid-size regional plan, that equals tens of millions in preventable annual losses recoverable only through systematic audit and intelligent detection.
Underpayment & Revenue Loss
Claims paid below contract rates due to coordination of benefits errors, duplicate payment credits, or capitation reconciliation gaps represent revenue your plan is owed but may never recover without structured post-pay review.
Fraud, Waste & Abuse Exposure
FWA patterns upcoding, unbundling, phantom billing, duplicate submissions go undetected in high-volume claims environments without AI-assisted anomaly detection and dedicated investigative review workflows, monitoring systems.
Audit & Compliance Penalties
CMS RADV audits, state insurance department market conduct reviews, and internal compliance findings all increase in severity when payment integrity gaps are systemic. Corrective action plans, civil monetary penalties, and reputational damage follow.
Contract Compliance Drift
When fee schedules, carve-outs, bundles, and specialty arrangements are not continuously validated against actual adjudication, contractual variance compounds silently, until a provider dispute, audit finding, or reconciliation project surfaces the gap.
Retroactive Recovery Cost
Every claim payment error discovered post-adjudication costs significantly more to resolve than it would have to prevent. Recovery workflows, provider disputes, administrative burden, and refund timelines all erode the net value of late-stage corrections.
Pre-pay integrity + post-pay audit: A complete control architecture
PRE-PAY INTEGRITY
Stop payment errors before they occur.Pre-pay integrity prevents incorrect payments before adjudication, eliminating costly downstream recovery and correction efforts.
- Claim edit rules and automated validation logic
- Eligibility and benefit verification at submission
- Medical necessity and prior authorization checks
- Duplicate claim detection and suppression
- Fee schedule alignment and modifier validation
- High-risk claim flagging before payment release
- Coordination of benefits verification
- Procedure-diagnosis edit validation (CCI edits)
POST-PAY AUDIT & RECOVERY
Identify and recover incorrect payments. Post-pay audit catches errors missed by pre-pay controls, recovers overpayments, and builds insights to improve upstream validation rules.
- Systematic claims audit across paid claim populations
- Overpayment identification and quantification
- Provider refund request management and tracking
- Contract compliance validation against adjudicated payments
- FWA pattern review and case documentation
- COB and subrogation coordination for eligible recoveries
- Third-party liability claim review and recovery
- Audit findings translated into pre-pay rule enhancements

Clinical Claims Integrity & Medical Review
What we do?
- Medical necessity review for high-cost and high-volume procedures
- Diagnosis-procedure edit validation (CCI, NCCI, LCD/NCD compliance)
- Inpatient DRG validation and outlier payment review
- Outpatient APC grouping accuracy and pass-through payment review
- Same-day surgery and place-of-service validation
- Level of care and admission criteria review for inpatient claims
- Readmission and concurrent hospitalization detection
- Physician specialty billing validation against credentialed procedures
- Experimental and investigational treatment identification
- Global surgery and post-operative period billing review
- Modifier accuracy validation and upcoding detection
Why Clinical Review Matters Financially?
Clinical claims represent the majority of total medical spend. Inaccuracies in DRG assignment, medical necessity determination, or procedure-diagnosis pairing translate directly to overpayment on high-cost claims. A single inpatient DRG error can represent $15,000–$80,000+ in recoverable overpayment per claim.
Measurable Financial Outcome
Plans engaging in systematic clinical integrity review typically uncover overpayment rates of 2–4% in inpatient populations and 3–6% in high-cost outpatient categories, achieving net recovery multiples of four to eight times audit cost, driving significant financial return and compliance assurance.
Coordination of Benefits & Subrogation Recovery
What we do?
- Primary and secondary payer identification and verification
- Medicare Secondary Payer (MSP) compliance and recovery
- Commercial COB coordination and claims reprocessing
- Workers' compensation and auto liability identification
- IRMAA and Part D coordination for dual-eligible populations
- Retroactive COB review and recovery on historical claim populations
- Subrogation opportunity identification and case initiation
- Third-party liability screening and coordination
- COB dispute resolution and provider follow-up
- Ongoing eligibility monitoring for coverage change detection
Why COB Failures Are High-Cost?
COB errors are among the most financially significant payment integrity failures, as plans frequently become the primary payer on claims another coverage source should bear. Undetected COB issues across a member population can represent 1–3% of total claims spend in recoverable or avoidable payments.
Measurable Financial Outcome
AnnexMed's COB recovery workflows consistently deliver a 3:1 to 6:1 return on program investment. Retroactive recovery on historical populations often represents the largest discrete financial finding in a payment integrity audit, providing substantial revenue recapture and measurable ROI for plans.
Fraud, Waste & Abuse Detection & Investigation
What we do?
- Real-time FWA screening on incoming claims prior to adjudication
- Systematic post-pay population review for fraud pattern identification
- Provider billing anomaly analysis and statistical outlier detection
- Duplicate claim submission and identity fraud detection
- Geographic and demographic plausibility analysis
- High-risk specialty and service category monitoring
- Case documentation and evidence compilation for referral
- SIU coordination and law enforcement referral support
- CMS fraud reporting and regulatory notification management
- Corrective action and provider remediation follow-up
Why AI-led FWA detection is non-negotiable?
Manual FWA detection finds a fraction of what is present. AI-assisted models trained on large claim populations identify emerging schemes and provider-specific anomalies that are invisible to rule-based systems detecting patterns that, once surfaced, often yield recoveries spanning multiple benefit years.
Measurable Financial Outcome
FWA programs using AI-assisted detection routinely identify 30–60% more recoverable cases than rule-based systems alone. By catching issues early with pre-pay identification, plans can prevent incorrect payments entirely, avoiding costly recovery, provider disputes, and downstream administrative burden.
Contract Compliance & Fee Schedule Validation
What we do?
- Fee schedule loading accuracy verification and validation
- Contracted rate vs. paid amount variance analysis
- Carve-out, bundle, and specialty-specific arrangement compliance
- Capitation and shared-risk contract reconciliation
- Risk corridor and stop-loss arrangement validation
- Value-based contract performance and payment accuracy review
- Retroactive rate adjustment identification and recovery
- Provider contract term extraction and payment rule mapping
- New contract implementation validation and go-live audit
- Ongoing contract drift monitoring across provider panel
Why Contract Compliance Requires Review?
Fee schedule and contract term errors are rarely one-time events, typically systematic, generating the same overpayment on every claim until detected. A misconfigured contract term for a high-volume specialty can generate hundreds of thousands in overpayment before surfacing in a standard audit cycle.
Measurable Financial Outcome
Contract compliance reviews regularly identify 1–2% of total contracted spend in systematic overpayments. The high volume, repeatability, and complexity of contract-driven errors make this one of the highest-ROI and most impactful components of a structured, enterprise-wide payment integrity program.
Identifying the systematic patterns in provider billing data that reveal where overpayment is concentrated.
What we do?
- Overpayment quantification and recovery package preparation
- Demand letter generation and provider notification
- Voluntary refund solicitation and payment tracking
- Recoupment offset coordination with claims processing
- Provider dispute management and appeal review
- Payment plan negotiation for high-value recovery cases
- Statute of limitations compliance and timely filing management
- Recovery rate tracking and portfolio performance reporting
- Regulatory reporting for recoveries above threshold amounts
- Refund receipt reconciliation and financial posting
- Closed-loop feedback to pre-pay rule improvement
Why dedicated recovery expertise matters?
Overpayment recovery is operationally intensive and legally sensitive. Mismanaged demands trigger provider disputes, strain network relationships, and risk CMS compliance findings. AnnexMed’s experienced specialists carefully balance financial recovery with provider relations and regulatory compliance.
Measurable Financial Outcome
AnnexMed's recovery programs achieve average net recovery rates of 75–85% of identified overpayments, well above industry benchmarks. Dispute rates are kept below 12% by using accurate documentation, compliant demand processes, and consistent follow-up to ensure recoveries are maximized efficiently.
Payment Integrity Analytics & Reporting
What we do?
- Claims payment accuracy rate by service category, specialty, and provider
- Overpayment identification and recovery performance dashboards
- FWA detection rate, case volume, and investigation outcome tracking
- Contract compliance variance reporting by agreement and provider group
- Pre-pay vs. post-pay catch rate comparison and program efficiency metrics
- AI model performance tracking: sensitivity, specificity, and improvement trends
- Year-over-year payment accuracy benchmarking
- Medical cost impact attribution by integrity program component
- Regulatory audit readiness reporting (CMS, state DOI, NCQA)
- Executive-level financial impact summary for CFO and board reporting
Why analytics close the loop?
Payment integrity programs without robust analytics are financially blind. Without visibility into what is being caught, what is being missed, and where financial exposure concentrates, plans cannot improve detection, justify program investment, or demonstrate ROI to executive leadership and regulators.
Measurable Financial Outcome
Plans with structured payment integrity analytics programs show measurable year-over-year improvements in overall accuracy. AI-assisted programs typically achieve 15–25% higher overpayment detection rates within the first 24 months of deployment, driving faster recovery and stronger financial control.
