Adding Charge Items for Diagnostic Tests
After a lab or imaging provider is activated by SigmaMD, you can set up charge items for its available tests.
Step 1: Navigate to the Diagnostic Providers Settings
Go to Practice Settings > Diagnostic Providers to view the list of diagnostic providers configured for your practice.
For providers with Active status, you’ll see the Interface Type displayed as either:
- Electronic
- Fax
Step 2: Open Charge Items
Click on the View charge items icon next to the provider.

This opens a page where all billable charge items (lab or imaging tests) are managed.
Note: The list will be empty initially. To display and configure items, pricing must first be added.
Step 3: Add Pricing Information
For Electronic Interface Providers
SigmaMD preloads the provider’s compendium of tests. These won’t appear until pricing is added.
- Click the Add button in the top-right.
- Choose one of two options:
Option A: Add Item-by-Item
- Click Item
- Search by test name or code
- Set Markup and Sales Tax (if applicable)
- See this guide to set markup or tax at the provider-level
- Enter the Base Price (use $0 if no patient payment is collected in the clinic).
- The Retail Price is calculated automatically.
- Click Save or Save and Add More

Option B: Upload CSV
- Click Upload Pricing
- Use a CSV file with two columns:
Code
– the lab or imaging test codePrice
– the base price (no dollar signs or commas)- Use $0 if no patient payment is collected in the clinic
- Set markup and tax, which is applied for all tests in the upload file.
- See this guide to set markup or tax at the provider-level
- Submit and wait for the confirmation email
- The email will include:
- Confirmation of successful uploads
- Errors for codes not processed (invalid format or no longer supported)

For Fax Interface Providers
These providers do not have a preloaded compendium. You’ll need to create each test manually:
- Click Add
- Search by CPT code or test name
- Enter the test code and name as provided by the diagnostic provider
- Set Markup and Sales Tax (if applicable)
- See this guide to set markup or tax at the provider-level
- Enter the Base Price (use $0 if no patient payment is collected in the clinic).
- The Retail Price is calculated automatically.

Step 4: Billing Patients
When using "Pay in Clinic," the practice bills the patient directly. For guidance on creating an invoice for lab or imaging orders, follow this article: How to Create a Patient Invoice for Lab and Imaging Orders
