💡 Accountant's Note
Hospitals often don't own expensive implants (like artificial hips). They sit in the hospital, but the hospital only 'buys' them from the vendor the second they are put into a patient.
Practitioner & Systems Framework
💻 ERP Architecture
Consignment implants (orthopedic implants, cardiac stents, spinal implants) are high-value devices held in the hospital on consignment — they remain the vendor's property until the moment of implantation. The hospital maintains a consignment log per vendor showing all devices held but not yet used. When a device is implanted: (a) the purchase is triggered (Accounts Payable: Device Vendor); (b) the expense is recognized immediately (the device goes directly into the patient, not into inventory). Never put consignment implants on the hospital's balance sheet as its own inventory — it is custodial property until used. Reconcile the consignment log to vendor consignment statements monthly.
⚠️ Audit Flags
Auditors physically count consignment implants held in the OR, central supply, and procedure areas and reconcile to the consignment log and vendor statements. Implants recorded on the hospital's own balance sheet (as inventory) when they belong to the vendor overstates assets. Any implants that are damaged, expired, or recalled while on consignment create a dispute with the vendor — the hospital's liability (if any) depends on the custody agreement.
📄 Required Documentation
Consignment agreement with the device vendor (terms, liability for loss/damage), consignment log (items held, serial numbers, vendor), surgical implant record (patient procedure, device used, lot number, surgeon), Accounts Payable entry to vendor upon implantation, patient charge for the implant, vendor reconciliation of consignment log vs. their records, and FDA/regulatory device tracking compliance.
