Medical Billing - DME Software Item Inventory

In this installment of medical billing and DME software, we're going to cover the topic of item inventory. We're going to explain how the inventory functions work, what information inventory tables contain and how this all ties in with the medical billing of a claim.

Item inventory is a very large part of the DME system. Because DME billing is for durable medical equipment, thus the name DME, a lot of items get dispensed to the patient. These items range from small things like test strips for diabetics, to large items like wheelchairs, beds and oxygen concentrators. Some of these items are sold and some are rented. There alone lies a big distinction and the reason why the inventory tables have to be broken up into what are called purchased items and serialized items. Purchase items are pretty well self explanatory, but some explanation is needed for why rental items are referred to as serialized items.

Rental items are referred to as serialized items because each item that is rented has a unique serial number attached to it. This serial number is tracked for the purposes of billing monthly rentals, which is usually how either the patient or insurance company pays for these items. If a rental item has to be replaced because it is defective or broken, then a new item has to be issued and its serial number noted for future billing. The old item is then put back in inventory and either fixed or thrown away and deleted from inventory.

The information that is contained in inventory is more than what most people realize. It is more than just the description of the item. For purchase items, it includes how many of the items are in stock, how many sales of the item were made, so that companies can track how well an item performs, reorder points so that they don't run out and a number of other things. For rental items, the information includes when the item was rented, how many months of billing have occurred, when the item is scheduled for maintenance and a host of other items. Most normal inventory records contain anywhere from 30 to 100 fields depending on how much information the company wants to track and the capability of the software itself.

How does this all tie in with medical billing? Well, the biller has to know how each item needs to be billed. So for starters, they have to know if it is a rental or purchase item. They have to know the price of the item. They have to know when maintenance is due on a rental item so they can send a bill for that maintenance. They have to know when an item is low so that they can notify inventory, just in case they're not aware of it, which they should be. If a biller has to replace an item, they have to know what replacement items are available. The list of things that a medical biller needs in relation to inventory is endless.

Without item inventory tables, the medical billing process would be a total nightmare because billers wouldn't know where anything was, what it cost and if it was even in stock.
