Eligibility Errors
Where 340B program value is lost — key challenge areas
340B compliance failures and benefit under-capture share common root causes across covered entity types. The following represent the most significant sources of preventable revenue loss and compliance exposure in hospital 340B program management.
Patient Eligibility Determination Errors
340B savings apply only to drugs dispensed to eligible patients in qualifying outpatient encounters. Errors in patient eligibility screening — including failure to capture all qualifying encounter types, incorrect site-of-care attribution, and inadequate documentation of eligibility — result in both under-capture of legitimate savings and compliance exposure when ineligible patients are mistakenly included.
Split Billing System Failures
Split billing systems must accurately separate 340B-eligible from non-340B-eligible drug dispensing to prevent both under-capture and duplicate discount violations. System configuration errors, EHR integration failures, formulary updates, and new drug additions frequently create split billing inaccuracies that go undetected until HRSA audit.
Medicaid Duplicate Discount Violations
Federal law prohibits covered entities from receiving both 340B pricing and Medicaid rebates on the same drug unit. Non-compliance with the duplicate discount prohibition creates unlimited repayment liability to state Medicaid programs — and is among the most serious compliance risks HRSA auditors examine. Compliant split billing systems are the only reliable protection.
GPO Prohibition Violations
DSH hospitals and certain other covered entity types are prohibited from purchasing drugs through group purchasing organization (GPO) arrangements for use in 340B-eligible patient encounters. GPO prohibition compliance requires careful inventory separation and purchasing pathway management — violations create repayment obligations and program integrity risk.
Contract Pharmacy Compliance Complexity
Most covered entities dispense 340B drugs through contract pharmacy arrangements rather than in-house dispensing. Manufacturer restrictions on contract pharmacy participation — which have expanded significantly — combined with complex eligibility and dispensing record requirements make contract pharmacy compliance one of the highest-risk areas in 340B program management.
HRSA Audit Exposure
HRSA conducts ongoing audits of covered entities and their contract pharmacies. Audit findings — including eligibility determination failures, duplicate discount violations, and inadequate dispensing records — can result in significant repayment demands, corrective action plans, and in serious cases, program termination. Continuous audit-readiness documentation is the only reliable protection.
AnnexMed delivers 340B program management as a continuous compliance and capture optimization function — not a periodic audit. The following services are structured to maximize eligible drug cost savings while maintaining full regulatory compliance across all HRSA, Medicaid, and payer requirements.
340B Patient Eligibility Determination
Comprehensive patient eligibility screening across all outpatient encounter types: qualifying site-of-care identification, patient-level eligibility verification, encounter documentation standards, and eligibility audit trail maintenance — ensuring all qualifying encounters are captured and no ineligible patients are included.
Split Billing System Management
End-to-end split billing system configuration, validation, and ongoing maintenance: formulary management, EHR integration monitoring, new drug addition workflows, and systematic accuracy testing — preventing the split billing failures that create both under-capture and duplicate discount violations
Medicaid Duplicate Discount Prevention
Automated identification and tracking of Medicaid-covered encounters to prevent simultaneous 340B pricing and Medicaid rebate claims on the same drug unit — with state Medicaid program-specific compliance management and continuous duplicate discount monitoring across all payer submissions.
Contract Pharmacy Compliance Management
Contract pharmacy arrangement oversight: dispensing record accuracy, manufacturer restriction compliance tracking, eligibility documentation at point of dispensing, and contract pharmacy audit support — managing the highest-complexity compliance area in 340B program administration.
HRSA Audit Readiness Program
Continuous HRSA audit readiness documentation: eligibility determination records, split billing accuracy evidence, duplicate discount compliance documentation, GPO prohibition records, and corrective action documentation — structured to withstand HRSA audit scrutiny and minimize repayment exposure.
GPO Prohibition Compliance
Purchasing pathway management to ensure DSH hospitals and other GPO-prohibited covered entity types maintain compliant drug purchasing separation — with inventory tracking, purchase order validation, and GPO prohibition documentation maintained on a continuous basis.
Payer Billing Compliance
340B-specific payer billing requirement management: Medicare Part B billing compliance (340B modifier requirements), commercial payer 340B billing restriction monitoring, and reimbursement rate tracking — ensuring billing accuracy across all payer types and preventing claim denials attributable to 340B billing errors.
340B Program Analytics & Reporting
Comprehensive 340B performance reporting via ImpactBI.AI: program benefit capture by site and drug category, eligibility determination accuracy rates, split billing compliance metrics, contract pharmacy performance, and HRSA audit readiness scores — giving pharmacy directors and CFOs full visibility into program performance

Key billing & regulatory reference
Effective 340B program management requires command of the regulatory framework governing covered entity eligibility, drug pricing compliance, Medicaid duplicate discount prohibition, and HRSA audit standards. The following covers the most critical dimensions of 340B compliance and billing requirements.
Regulatory Dimension
Detail
AnnexMed Approach
340B Statute
Section 340B of the Public Health Service Act — requires manufacturers to offer covered outpatient drugs at ceiling price to eligible covered entities; program administered by HRSA Office of Pharmacy Affairs
Full statutory compliance framework integrated into all eligibility determination, purchasing, and dispensing workflows
Covered Entity Eligibility
DSH hospitals, Critical Access Hospitals, Rural Referral Centers, Sole Community Hospitals, Children's Hospitals, and federal grantees (FQHCs, Ryan White, etc.) — each with specific eligibility maintenance and documentation requirements
Covered entity type-specific compliance protocols maintained for each client; eligibility documentation updated continuously
Duplicate Discount Prohibition
Federal prohibition on receiving both 340B pricing and Medicaid drug rebates on the same drug unit — violations carry unlimited repayment liability to state Medicaid programs and are a primary HRSA audit focus
Automated duplicate discount protection covers 100% of drug transactions; state-specific Medicaid requirements managed separately
GPO Prohibition
DSH hospitals and certain other covered entities prohibited from purchasing 340B-eligible drugs through GPO arrangements — violations require repayment and create program integrity risk; inventory separation and purchasing controls required
GPO prohibition compliance monitored continuously; purchasing pathway validation integrated into drug procurement workflows
Contract Pharmacy Rules
HRSA guidance allows contract pharmacy arrangements with documentation requirements; manufacturer restrictions have significantly expanded since 2020, limiting contract pharmacy participation for many drugs — compliance complexity continues to increase
Manufacturer restriction tracking maintained by drug and pharmacy; dispensing record requirements met for all active contract arrangements
Medicare Part B Billing
340B drugs billed to Medicare Part B under the average sales price (ASP) minus 22.5% reimbursement formula for hospital outpatient departments — modifier requirements distinguish 340B-acquired drugs; non-compliance creates claim adjustment risk
Medicare Part B modifier compliance and reimbursement rate monitoring integrated into billing workflow for all qualifying claims
HRSA Audit Standards
HRSA conducts covered entity and contract pharmacy audits assessing: patient eligibility records, split billing accuracy, duplicate discount compliance, GPO prohibition adherence, and dispensing record completeness — findings may require repayment, corrective action, or program termination
Continuous HRSA audit readiness documentation maintained; audit finding risk quantified and tracked through real-time compliance dashboards
Hospitals that implement AnnexMed’s Case Management and Utilization Management billing support consistently achieve measurable improvements in status accuracy, denial reduction, and length of stay performance across a 12-month engagement cycle.

Why AnnexMed for 340B program billing
Most covered entities manage their 340B program with a combination of point-in-time audits, manual eligibility reviews, and reactive compliance corrections. AnnexMed operates this as a continuous compliance and capture optimization function — embedding automated eligibility screening, split billing monitoring, and HRSA audit readiness documentation into your pharmacy and billing workflow on an ongoing basis.
Continuous 340B Compliance — Not a Periodic Audit
Our 340B program management operates as an ongoing function, not an annual review. Patient eligibility screening, split billing accuracy monitoring, duplicate discount protection, and contract pharmacy compliance run continuously — preventing the compliance drift and benefit under-capture that occur when 340B management is treated as a periodic engagement.
AI-Driven Eligibility Determination at Encounter Scale
ImpactRCM.AI screens every outpatient encounter against 340B eligibility criteria in real time — identifying qualifying encounters missed by manual processes and flagging ineligible encounters before they create compliance exposure. Hospitals typically capture 15–25% more qualifying encounters in the first year following implementation.
Automated Duplicate Discount Protection
Medicaid duplicate discount compliance is automated and transaction-level — not sampled. Every drug transaction is screened against Medicaid coverage status to prevent simultaneous 340B pricing and rebate claims, with state-specific Medicaid program requirements managed separately for each covered entity.
Contract Pharmacy Complexity Managed End-to-End
Contract pharmacy compliance — including manufacturer restriction tracking, dispensing record accuracy, and eligibility verification at point of dispensing — is among the most complex areas of 340B program management. AnnexMed manages this as a dedicated service, maintaining compliance as manufacturer restrictions continue to expand.
HRSA Audit Readiness as a Continuous State
HRSA audit documentation is maintained continuously rather than assembled reactively during audit preparation. Covered entities working with AnnexMed can respond to HRSA audit requests within days rather than weeks — with complete eligibility records, split billing evidence, duplicate discount documentation, and corrective action histories organized to HRSA audit format requirements.
No Additional Technology Cost
ImpactRCM.AI and ImpactBI.AI are included in the AnnexMed engagement — covered entities receive AI-powered eligibility screening, split billing monitoring, duplicate discount protection, and 340B program analytics without incremental technology investment.
