Healthcare Accounts Payable Glossary

Auxtri's healthcare AP glossary defines 57+ terms used by hospital and health system accounts payable departments. Search by keyword or filter by category — from GPO contracts and 3-way matching to EDI transactions and vendor compliance.

What is healthcare accounts payable?

Healthcare accounts payable (AP) is the department within a hospital or health system responsible for processing vendor invoices, making payments, reconciling statements, and managing vendor relationships. Healthcare AP is more complex than general AP due to GPO contracts, medical supply distribution networks, HIPAA compliance, and the critical nature of supply chain operations — a delayed payment can result in a credit hold that disrupts medical supply deliveries to patient care areas.

Payment Methods

ACH (Automated Clearing House)
An electronic funds transfer system used by healthcare organizations to pay vendors. ACH payments are cheaper and faster than paper checks and are the preferred payment method for most hospital AP departments. Healthcare organizations typically pay medical supply distributors, pharmaceutical companies, and service vendors via ACH.
Related:EFTABA Routing NumberVirtual Card
EFT (Electronic Funds Transfer)
A broad term for any electronic movement of money between bank accounts. In healthcare AP, EFT usually refers to ACH payments or wire transfers sent to vendors. The HIPAA 835 transaction is the healthcare-specific EFT/remittance advice standard.
Related:ACHEDI 835
Wire Transfer
A same-day electronic payment method used for urgent or high-value vendor payments. Wire transfers are more expensive than ACH ($15–$30 per transaction) but guarantee same-day settlement. Healthcare AP departments typically reserve wires for time-sensitive situations like preventing a credit hold on critical medical supplies.
Related:ACHCredit Hold
Virtual Card
A single-use credit card number generated for a specific vendor payment. Healthcare AP departments use virtual cards to earn rebates (typically 1–2% of spend), improve payment security, and automate remittance delivery. Vendors receive the virtual card number and charge it for the exact invoice amount.
Related:P-CardRemittance Advice
P-Card (Purchasing Card)
A corporate credit card used for low-value procurement purchases. In healthcare, p-cards are common for office supplies, maintenance items, and emergency purchases that bypass the standard PO process. P-card transactions require reconciliation by the AP department.
Related:Virtual CardPurchase Order
Check (Paper Check)
A paper payment instrument that healthcare organizations are increasingly moving away from. Processing a paper check costs $5–$15 per transaction (printing, mailing, reconciliation) compared to $0.25–$0.50 for ACH. Many hospital AP departments have vendor payment modernization initiatives targeting 80%+ electronic payment rates.

Document Types

Purchase Order (PO)
A document issued by a hospital to a vendor authorizing a purchase. In healthcare, POs are generated from the hospital's materials management or ERP system and reference GPO contract pricing. The PO number is the primary cross-reference key between the order, the invoice, and the goods receipt.
Related:3-Way MatchEDI 850Invoice
Invoice
A bill sent by a vendor to a hospital requesting payment for goods or services delivered. Healthcare organizations process 100,000–300,000+ invoices per year. Each invoice must be matched against a PO and goods receipt (3-way match) before payment. Invoice processing efficiency is one of the key metrics for hospital AP departments.
Related:3-Way MatchEDI 810Invoice Exception
Credit Memo
A document issued by a vendor reducing the amount owed by the hospital. Common reasons in healthcare include returned medical supplies, pricing errors against GPO contract rates, damaged goods, and vendor rebates. Credit memos must be applied against the original invoice in the hospital's ERP system.
Related:Debit MemoInvoice
Debit Memo
A document issued by either party increasing the amount owed. In healthcare AP, the hospital may issue a debit memo to a vendor for shortages, quality issues, or pricing discrepancies. The vendor may issue one for additional charges like freight, handling, or restocking fees.
Related:Credit MemoInvoice
Remittance Advice
A document accompanying a payment that details which invoices are being paid. In healthcare, the HIPAA 835 transaction is the standard electronic remittance advice format. For AP vendor payments, the remittance advice tells the vendor which invoices, credit memos, and adjustments are included in the payment.
Related:EDI 835ACHEFT
Statement
A periodic summary sent by a vendor listing all outstanding invoices, payments received, and the current balance owed. In healthcare AP, statement reconciliation is one of the most time-consuming tasks — the average statement takes 30–60 minutes to reconcile manually because each line item must be looked up individually in the hospital's ERP system.
Related:Statement ReconciliationInvoice
Goods Receipt (GR)
A record in the hospital's ERP system confirming that ordered goods were physically received at the dock. The goods receipt is the third leg of 3-way matching — it verifies that the hospital actually received what the vendor invoiced. In healthcare, the receiving department scans or enters receipts for medical supplies, pharmaceuticals, and other materials.

Healthcare-Specific

GPO (Group Purchasing Organization)
An entity that negotiates volume-based purchasing contracts with manufacturers and distributors on behalf of member healthcare organizations. Major GPOs include Vizient, Premier, HPG, and Intalere. GPO contracts establish pricing, payment terms, and rebate structures that flow through to the hospital AP department. Most hospital purchases reference a GPO contract number.
Related:Purchase OrderPayment Terms
Charge Master (CDM)
A comprehensive list of billable items and their prices maintained by a hospital. While primarily a revenue cycle concept, the charge master impacts AP when supply costs are compared against reimbursement rates. AP teams may reference charge master data when analyzing the cost-effectiveness of different medical supply vendors.
HCPCS (Healthcare Common Procedure Coding System)
A standardized coding system used to identify healthcare products, supplies, and services. HCPCS codes appear on invoices for durable medical equipment (DME), prosthetics, orthotics, and medical supplies. Healthcare AP teams use HCPCS codes to verify that invoiced items match contract pricing and are billable to payers.
Related:CPT
CPT (Current Procedural Terminology)
A medical code set maintained by the AMA for reporting medical procedures and services. While primarily used for clinical billing, CPT codes appear on invoices from physician service vendors, staffing agencies, and outsourced clinical service providers that healthcare AP departments process.
Related:HCPCS
EDI 835 (Health Care Payment/Remittance Advice)
The HIPAA-mandated X12 transaction set for electronic remittance advice in healthcare. The 835 details how a health plan adjudicated claims — which charges were paid, denied, or adjusted. While primarily a revenue cycle document, AP departments may encounter 835s when reconciling payments from other healthcare organizations.
Related:EDI 837Remittance AdviceEDI
EDI 837 (Health Care Claim)
The HIPAA-mandated X12 transaction set for submitting healthcare claims electronically. The 837 is the electronic equivalent of the CMS-1500 (professional) or UB-04 (institutional) paper claim form. Like the 835, this is primarily a revenue cycle document but intersects with AP when hospitals receive invoices from clearinghouses or billing services.
Related:EDI 835EDI
NPI (National Provider Identifier)
A unique 10-digit identification number assigned by CMS to healthcare providers. NPI numbers use the Luhn algorithm for check-digit validation. Healthcare AP departments use NPI numbers for vendor master management, provider enrollment verification, and 1099 reporting for physician service vendors.
Related:DUNS NumberVendor Master
Medical Supply Distributor
A company that warehouses and distributes medical supplies from manufacturers to healthcare organizations. Major distributors include Cardinal Health, McKesson, Medline, and Owens & Minor. These distributors generate the highest volume of invoices for hospital AP departments — a single large distributor relationship may produce 20,000+ invoices per year for one hospital.
Related:GPOPurchase Order
Credit Hold
A vendor-initiated block on new orders when a hospital's outstanding balance exceeds a threshold or invoices age past an agreed number of days. Credit holds are particularly critical in healthcare because they can delay delivery of medical supplies, pharmaceuticals, and equipment needed for patient care. Preventing credit holds is a top priority for hospital AP departments.
Related:AP AgingStatement
IDN (Integrated Delivery Network)
A network of healthcare organizations — hospitals, clinics, physician practices — that are owned or affiliated under a single parent entity. IDNs typically centralize AP operations in a shared services center, processing invoices for all facilities from one location. Large IDNs process 500,000+ invoices per year.

Processes

3-Way Match
The process of comparing three documents before approving an invoice for payment: the purchase order (PO), the goods receipt (GR), and the vendor invoice. All three must agree on item, quantity, and price. In healthcare, 3-way matching is the standard for supply chain invoices from medical distributors. Mismatches create invoice exceptions that require manual resolution.
Related:2-Way MatchInvoice ExceptionPurchase OrderGoods Receipt
2-Way Match
A simplified matching process that compares only the PO and the invoice (no goods receipt). Healthcare organizations use 2-way matching for service invoices, subscriptions, and other non-inventory purchases where physical receipt verification is not applicable.
Related:3-Way MatchInvoice
GRN (Goods Receipt Note)
A document or ERP transaction confirming that goods were received at the hospital's dock. The GRN captures receiving date, quantities, condition, and the receiving person. In healthcare, GRNs are created by materials management staff when medical supply shipments arrive and are scanned into the ERP system.
Related:Goods Receipt3-Way Match
Invoice Exception
An invoice that fails automated matching rules (price variance, quantity discrepancy, missing PO, etc.) and requires manual review. Healthcare organizations typically see a 20–30% exception rate on supply chain invoices. Each exception takes 15–30 minutes to research and resolve, making exception management one of the largest AP labor costs.
Related:3-Way MatchInvoiceFirst-Pass Match Rate
Duplicate Invoice Detection
The process of identifying and blocking duplicate invoice submissions before payment. In healthcare, duplicates arise from vendor resubmissions, EDI/paper overlap (same invoice sent both electronically and on paper), and statement line items mistakenly entered as new invoices. Duplicate payments cost the average large hospital $50,000–$200,000 per year.
Related:InvoiceInvoice Exception
Statement Reconciliation
The process of comparing a vendor statement against the hospital's AP records to identify discrepancies. Each invoice on the statement must be looked up in the ERP system to determine if it is paid, open, in dispute, or unknown. This is one of the most time-consuming tasks in healthcare AP — the average statement takes 30–60 minutes to reconcile manually.
Related:StatementVendor Inquiry Response
Vendor Inquiry Response
The process of responding to vendor emails asking about invoice status, payment timing, or statement discrepancies. Healthcare AP teams receive thousands of vendor inquiry emails per month. Each inquiry requires an ERP lookup and a drafted response, taking 5–10 minutes manually. Auxtri automates this process, reducing response time to under 30 seconds.
Related:Statement ReconciliationCredit Hold
Vendor Onboarding
The process of setting up a new vendor in the hospital's ERP system, including collecting W-9 forms, verifying EIN/TIN, validating DUNS numbers, establishing payment methods (ACH, check), and entering GPO contract pricing. Healthcare vendor onboarding is more complex than other industries due to compliance requirements around provider enrollment and credentialing.
Related:Vendor MasterDUNS NumberW-9
Vendor Master
The master data record for a vendor in the hospital's ERP system. Contains legal name, addresses, EIN/TIN, DUNS number, payment terms, bank information for ACH, and contact details. Maintaining accurate vendor master data is critical for 1099 reporting, duplicate vendor prevention, and payment accuracy.
Related:Vendor OnboardingDUNS NumberNPI
Payment Terms
The agreed-upon conditions under which a vendor expects payment — typically expressed as "Net 30" (full amount due in 30 days) or "2/10 Net 30" (2% discount if paid within 10 days, otherwise due in 30). In healthcare, payment terms are negotiated at the GPO contract level and vary by distributor.
Related:GPOEarly-Pay Discount
Early-Pay Discount
A percentage discount offered by a vendor for paying an invoice before the standard due date. Common in healthcare: 2/10 Net 30 offers a 2% discount for payment within 10 days. The annualized return on a 2/10 Net 30 discount is approximately 36.7%. Healthcare organizations that automate vendor communication can capture more discounts by resolving invoice inquiries faster.

Shared Services
A centralized AP operation that processes invoices for multiple facilities within an IDN or health system. Shared services centers consolidate vendor relationships, standardize processes, and achieve economies of scale. A healthcare shared services center may handle AP, payroll, and general accounting for 10–50+ hospital facilities.

Technology

EDI (Electronic Data Interchange)
A standardized electronic format for exchanging business documents between trading partners. In healthcare supply chain, EDI X12 transaction sets (810, 850, 855, 856) automate the purchase-to-pay cycle between hospitals and medical supply distributors. EDI reduces manual data entry, speeds up invoice processing, and improves accuracy.
Related:X12VANEDI 810EDI 850
X12
The ANSI ASC X12 standard that defines the format for EDI transactions in North America. X12 transaction sets are identified by 3-digit numbers: 810 (Invoice), 850 (Purchase Order), 855 (PO Acknowledgment), 856 (ASN), 835 (Remittance Advice), 837 (Claim). Healthcare organizations use both procurement X12 sets and HIPAA-mandated clinical X12 sets.
Related:EDIEDI 810EDI 850
EDI 810 (Invoice)
The X12 transaction set for electronic invoices. An EDI 810 contains invoice number, date, line items with quantities and prices, payment terms, and ship-to/bill-to information. The 810 is the electronic equivalent of a paper invoice and is the primary EDI document processed by healthcare AP departments.
Related:EDIEDI 850Invoice
EDI 850 (Purchase Order)
The X12 transaction set for electronic purchase orders. An EDI 850 contains the PO number, order date, ship-to address, line items with product IDs and quantities, and pricing from the GPO contract. The 850 initiates the procurement cycle and is the document that the vendor's 810 invoice is matched against.

cXML (Commerce eXtensible Markup Language)
An XML-based standard for business-to-business e-commerce transactions. In healthcare procurement, cXML is used for punchout catalog integrations where hospital buyers shop on a vendor's website and the order flows back into the hospital's ERP system. cXML purchase orders and invoices are an alternative to EDI X12 for certain vendors.
Related:Punchout CatalogEDI
Punchout Catalog
An e-procurement integration where hospital buyers "punch out" from their ERP system to a vendor's website, browse and select products, and return a shopping cart to the ERP for PO generation. Punchout catalogs are common in healthcare for specialty items, custom equipment, and vendors that maintain complex product configurations.

ERP (Enterprise Resource Planning)
The core business system where healthcare organizations manage finance, procurement, inventory, and AP. Common healthcare ERPs include Infor CloudSuite FSM, Workday Financial Management, Oracle Fusion, PeopleSoft, and Lawson. The ERP is where POs are generated, invoices are matched, payments are processed, and vendor master data is maintained.

AP Automation
Technology that automates accounts payable processes — invoice capture, data extraction, matching, approval routing, and payment. In healthcare, AP automation reduces the cost per invoice from $10–$15 (manual) to $2–$4 (automated). Auxtri focuses on automating vendor communication — the inquiry and statement reconciliation workflows that AP automation platforms typically do not address.

Compliance

1099 Reporting
IRS requirement for organizations to report payments of $600+ per year to non-employee vendors. Healthcare AP departments must accurately track vendor EIN/TIN numbers and annual payment totals to file 1099-NEC (services) and 1099-MISC (rents, medical payments) forms. Incorrect vendor tax IDs result in B-Notice penalties and potential backup withholding.
Related:W-9Vendor Master
W-9
IRS form that vendors complete to provide their taxpayer identification number (TIN/EIN) and certification. Healthcare AP departments collect W-9s during vendor onboarding and must have a valid W-9 on file before issuing payment. An expired or missing W-9 can trigger backup withholding at 24% on vendor payments.
Related:1099 ReportingVendor Onboarding
Escheatment (Unclaimed Property)
State laws requiring organizations to remit uncashed checks and unclaimed vendor credits to the state after a dormancy period (typically 1–5 years). Healthcare AP departments must track outstanding checks, unresolved vendor credits, and uncashed refunds, and file annual escheatment reports. Non-compliance results in penalties and audits.
Related:Check
Prompt Payment Laws
State and federal regulations that require timely payment of invoices, sometimes with interest penalties for late payment. Several states have healthcare-specific prompt payment requirements. Healthcare AP departments must track payment timing to ensure compliance and avoid interest charges.

False Claims Act
A federal law that imposes liability on entities that defraud government programs, including Medicare and Medicaid. In healthcare AP, the False Claims Act is relevant because knowingly paying fraudulent vendor invoices or overpaying due to inadequate controls can create liability. Proper invoice matching and vendor validation are compliance safeguards.

Metrics

DPO (Days Payable Outstanding)
A metric that measures the average number of days a healthcare organization takes to pay its vendor invoices. DPO = (Accounts Payable / Cost of Goods Sold) x Number of Days. Healthcare CFOs use DPO to manage cash flow — a higher DPO preserves cash but risks vendor relationship damage and credit holds. Typical healthcare DPO ranges from 30–55 days.
Related:AP AgingPayment Terms
Invoice Cycle Time
The average number of days from invoice receipt to payment. In healthcare, the best-in-class invoice cycle time is 5–10 days for matched invoices. Manual AP departments average 15–25 days. Reducing cycle time captures more early-pay discounts and improves vendor satisfaction.
Related:Early-Pay DiscountDPO
First-Pass Match Rate
The percentage of invoices that pass automated 3-way matching without requiring manual intervention. Best-in-class healthcare AP departments achieve 75–85% first-pass match rates. A low match rate means more exceptions, more manual work, and higher cost per invoice. Improving match rates requires accurate vendor master data, correct PO pricing from GPO contracts, and timely goods receipts.
Related:3-Way MatchInvoice ExceptionCost Per Invoice
Cost Per Invoice
The fully loaded cost to process one invoice from receipt to payment. Includes labor, technology, postage, and overhead. Manual healthcare AP departments typically see $10–$15 per invoice. Highly automated departments achieve $2–$4. This metric is the primary benchmark for AP department efficiency.
Related:AP AutomationFirst-Pass Match Rate
AP Aging
A report that categorizes outstanding invoices into time-based buckets (Current, 1–30, 31–60, 61–90, 90+ days) based on the invoice date. Healthcare CFOs and AP managers use aging reports to monitor payment performance, identify vendors at risk of credit holds, and ensure compliance with prompt payment laws. The distribution across aging buckets is a key indicator of AP department health.
