Chargeback Management
Wholesaler Chargeback Reconciliation and Recovery on 340B-Purchased Inventory
Wholesaler chargeback monitoring, reconciliation, and recovery on 340B-purchased inventory. Discrepancy investigation across wholesaler, manufacturer, and TPA data sources — capturing the cost-recovery dollars that flow between wholesalers and manufacturers on every 340B-eligible dispense.

The Reality
Why wholesaler chargebacks are the quietest source of 340b revenue loss?
Every 340B-eligible dispense triggers a chain of cost-recovery transactions: the wholesaler ships at WAC, the covered entity receives 340B pricing, and the wholesaler chargebacks the manufacturer for the difference. When that chain breaks — wrong NDC, expired contract, eligibility dispute, TPA discrepancy — chargeback dollars don’t flow correctly, and the covered entity carries the cost. Unlike duplicate discounts or manufacturer restrictions, chargeback failures don’t trigger enforcement. They just quietly drain margin.
Three-Party Reconciliation Complexity
Chargebacks involve three parties — wholesaler (Cardinal Health, McKesson, AmerisourceBergen), manufacturer, and covered entity. Each party maintains its own data, runs its own validation, and surfaces discrepancies on its own timeline. Reconciliation gaps between any two parties create chargeback failures the covered entity absorbs.
TPA Adds a Fourth Reconciliation Layer
For covered entities operating contract pharmacy arrangements, the third-party administrator (Apexus, SUNRx, Verity Solutions, Sentry Data Systems) adds a fourth reconciliation layer. TPA data must align with wholesaler chargeback data, manufacturer eligibility data, and contract pharmacy dispensing data. Misalignment across four sources is operationally common.
Manufacturer Eligibility Drift
Manufacturer chargeback eligibility changes quarterly — NDCs covered shift, contract pricing tiers update, eligible customer classes change. Covered entities running on stale manufacturer eligibility data submit chargeback claims that get rejected weeks or months after dispensing, with limited recovery opportunity.
Discrepancy Investigation Volume
A mid-size covered entity may process tens of thousands of chargeback transactions monthly. Discrepancies — wrong NDC mappings, contract reference errors, eligibility disputes, quantity mismatches — surface across this volume. Without dedicated investigation workflow, discrepancies sit unresolved and ultimately convert to write-off.
Aged Chargeback Recovery Window
Wholesaler chargeback recovery operates on short windows — typically 90 days from original transaction, with some manufacturer programs running shorter. Aged chargebacks that aren't investigated within window become permanent loss. Pharmacies without active aged chargeback infrastructure absorb cumulative losses quietly.
Multi-Site Health System Compounding
A multi-facility health system with 5 covered entity locations operating multiple contract pharmacies faces chargeback reconciliation across multiple wholesaler relationships, multiple TPAs, and dozens of manufacturer arrangements. Cross-site reconciliation gaps compound into substantial cumulative exposure.
Our approach
We run wholesaler chargeback management as standing recovery infrastructure
AnnexMed runs wholesaler chargeback management as dedicated recovery infrastructure — with three-party (wholesaler + manufacturer + covered entity) reconciliation across all major wholesalers, fourth-layer TPA data integration, manufacturer eligibility maintenance, discrepancy investigation workflow, and aged chargeback recovery sweep. Chargebacks become a managed recovery operation instead of a quiet write-off pipeline.
We serve hospital 340B programs across DSH hospitals, critical access hospitals, sole community hospitals, FQHCs, Ryan White clinics, and other HRSA-designated entities. Our team manages chargeback reconciliation across Cardinal Health, McKesson, and AmerisourceBergen — alongside the major 340B TPAs including Apexus, SUNRx, Verity Solutions, and Sentry Data Systems.
Recent client results
A 340-bed regional health system improved wholesaler chargeback recovery rate from 64% to 89% within 90 days of go-live, capturing approximately $1.3M in previously-rejected chargebacks. A multi-facility hospital system serving 5 covered entity locations identified $720,000 in aged chargeback recovery opportunity through 6-month historical sweep — chargebacks that would have aged past recovery windows without dedicated infrastructure. A community hospital with 220 beds reduced manufacturer chargeback rejection rate from 31% to 5.8% by implementing continuous manufacturer eligibility tracking and pre-submission validation.

Financial impact
What active chargeback management means in dollars?
For a hospital 340B program with substantial wholesaler chargeback volume, dedicated chargeback management regularly delivers $700K–$2.5M+ in net annual financial benefit through chargeback recovery improvement, aged chargeback capture, manufacturer eligibility maintenance, and TPA reconciliation accuracy. Most hospitals achieve full ROI on chargeback management within 5–7 months — often faster when significant aged chargeback recovery is available.
Fast Results
Chargeback recovery rate improvement shows within the first 90 days as three-party reconciliation infrastructure activates. Aged chargeback recovery typically pays back within 60 days through 6-month historical sweep.
Built for the Three Major Distributors
Wholesaler chargeback reconciliation supports Cardinal Health, McKesson, and AmerisourceBergen — the three distributors that handle the vast majority of hospital pharmacy inventory. Multi-distributor health systems don’t face vendor coverage gaps.

Technology
Powered by proprietary AI & analytics
AnnexMed’s technology stack was built for payer-specific operational demands, not adapted from provider-side billing tools. Risk adjustment accuracy, payment integrity, and credentialing compliance each require different data models, workflow logic, and reporting architectures than provider RCM. Our platform reflects that.

AI Agents & Intelligent Automation deploys autonomous AI agents across the full revenue cycle, automating eligibility verification, prior authorization, claims processing, payment posting, and denial management at hospital scale and speed.
Data & Analytics Platform
Data & Analytics Platform delivers real-time Power BI dashboards built for hospital executive visibility, including system-wide KPIs, service line performance, payer analysis, productivity, financial forecasting, and national benchmarking insights.
Intelligent AR Management
Intelligent AR Management handles A/R follow-up at hospital scale with intelligent worklists prioritized by dollar value and aging, payer-specific follow-up rules, automated escalation for high-value accounts, and full accountability for every claim.
Computer Assisted Coding
Computer Assisted Coding orchestrates hospital coding operation, intelligent chart assignment by service line, TAT tracking with SLA monitoring, quality audits with accuracy scoring, and coder performance management at enterprise scale.
Together, these platforms create a fully instrumented RCM operation where nothing falls through the cracks. You don’t interact with these systems directly, but the results they enable show up directly in your financial performance.
