Adding Non-Inventory Items

Non-inventory items are products or services that are not tracked by stock, such as procedures, lab tests, or imaging studies.

These items can still be categorized and priced for billing and reporting without tracking quantities or expiration dates.

Non-Inventory Table

Go to Billing → Charge Items and select the Non-inventory items tab at the top.

At the upper-right corner, click + Item, then choose one of the following:

  • Medication non-inventory

  • General non-inventory

A panel will open on the right side with the corresponding item form.

Adding a Medication Non-Inventory Item

Fill in the item details:

  • Medication: Type the medication name or Medi-Span code. If unit and strength are available, they will automatically populate.
  • Name: This field is prefilled with the selected medication, but you can update it if needed. 
  • Category: Assign it to an existing medication category.
  • Batch information: Add lot number, expiration date, package NDC, manufacturer, and supplier.
  • Markup: Use the category’s markup, apply a percentage, fixed amount, or none.

Adding Diagnostic Lab and Diagnostic Imaging Items

Diagnostic Lab and Imaging items follow a slightly different flow. These items are typically created inside a category that represents your lab or imaging provider (for example, Quest or LabCorp).

To add a diagnostic item:

  1. Go to Billing → Charge Items → Categories.
  2. Locate or create a category for your diagnostic provider.

    • The category type should be Diagnostic Lab or Diagnostic Imaging.


  3. Click View items for that category. You’ll see a list of existing test codes.

  • At the top right, click ➕ Add → Item. A side panel opens where you can enter test details.

Upload Diagnostic Pricing

Instead of adding items one by one, you can upload pricing for Diagnostic Lab or Imaging categories in bulk using a CSV file.

To upload pricing:

  1. Open the desired diagnostic category.

  2. Click the Add button in the top-right corner and select Upload pricing.

In the upload modal:

  • Choose file: upload a .csv file (maximum 5 MB).
  • Markup: choose from category, percentage, fixed, or no markup.
  • Sales Tax: choose a category default, another profile, or no tax.

  • File requirements differ slightly between Diagnostic Lab and Diagnostic Imaging. While Diagnostic Lab requires Code and Price columns, Diagnostic Imaging requires CPT Code, Price, and Test Name columns.

After uploading, click Confirm to import pricing. SigmaMD automatically updates or creates items in the selected diagnostic category based on the codes in your file.

How Items Appear in the Table

After saving, all new non-inventory items appear under the Non-inventory items tab.

Each entry displays key details, including Code, Base Price, Markup, and Tax Profile.

You can use filters such as Type, Category, Status, Code, and Expiration date to quickly find items or services.
