## Key terms

### UIN — Unique Inventory Number

A **UIN** (Unique Inventory Number) is a system-generated identifier assigned to a single physical unit of a product at the moment it is received into inventory. No two units share a UIN, even when they come from the same lot or shipment. The UIN travels with the graft or supply item through receiving, storage, and patient application, and is scanned in the **Procedures & Supplies** section of the Visit Wizard to link the unit to a clinical encounter.

### PAR level — Periodic Automatic Replenishment

A **PAR level** (Periodic Automatic Replenishment threshold) is the minimum quantity of a product that should be on hand at a facility. When stock falls to or below the PAR level, the system surfaces a replenishment alert so a `vendor_coordinator` or `admin` can reorder before a stockout occurs.

## The hub tiles

| Tile | Purpose |
|---|---|
| **Product Catalog** | Master list of every product your organization has configured (with a Products tab and a Vendors tab). Add products and edit SKU/HCPCS metadata here. |
| **Amniotic / Advance Treatment** | Receiving and management for amniotic membrane and advance-treatment products. |
| **Biologics / Matrix** | Receiving and management for biologic matrix products (HCPCS + manufacturer lot-format validation). |
| **Conservative Care Products** | Receiving and management for non-graft supplies (dressings, offloading, consumables). |
| **PRP** | Platelet-rich plasma kits. |
| **Ultrasonic Mist (UM)** | Ultrasonic mist therapy cartridges. |
| **IVR Tracking** | Tracks IVR submissions, outcomes, and vendor responses. See [IVR Tracking](./ivr-tracking.md). |
| **Clinician Inventory View** | A read-only, role-filtered view of what's available at a clinician's facility, without cost or AP data. |
| **Accounts Payable** | Vendor invoice intake, matching, payments, and disputes. See [Accounts Payable](./accounts-payable.md). |
| **Main Inventory** | The facility's stock and fulfillment view for what is physically on hand. |

<Note>
**PRP** and **Ultrasonic Mist** are their own categories alongside Amniotic, Biologics, and Conservative Care. Like conservative products, they flow through the standard deduction pipeline and do not require IVR prior authorization.
</Note>

## Other tools

- **FDA HCT/P Recall Lookup** — a lookup tool (not a hub tile) for checking received tissue products against FDA recall data.
- **Bulk operations** — shipment logging, vendor receiving, manual receipt, and provider assignment from a single landing page. See [Bulk inventory workflows](./bulk-operations.md).

## How the tiles connect

1. A product is defined in **Product Catalog** with its SKU, HCPCS, and category.
2. A shipment is received through the appropriate category tile (**Amniotic / Advance Treatment**, **Biologics / Matrix**, **Conservative Care Products**, **PRP**, or **Ultrasonic Mist**), generating a UIN for each unit.
3. If a payer requires prior authorization for a graft, an IVR is tracked in **IVR Tracking**.
4. Received units appear in inventory and become selectable in the Visit Wizard's Procedures & Supplies section.
5. Vendor invoices for received shipments are handled in **Accounts Payable**.
