The Incidental Pulmonary Nodule (IPN) component of the Early Lung Cancer Detection Registry (ELCDR) collects data on incidental pulmonary nodules identified outside of lung cancer screening exams.

A printable Exam form is also available for download to assist you with your internal workflow. However, data collected on printable forms must be submitted to the ELCDR via one of the three submission methods indicated below.
Note: Please do not mail printed forms to the ACR.
IPN Data Submission Methods
There are three options for submitting data to the ELCDR:
An online data entry form is available for manual data entry. Refer to Manual Data Entry Instructions for a general overview of the process and IPN Manual Entry: Register New Exam for how to start a new exam.
Data may be submitted for multiple exams simultaneously via flat file upload to the registry. See IPN Data File Upload for details.
Web-based data transmission allows you to send data directly from your software vendor or IT department, saving time and reducing the risk of errors.
Your facility is not obligated to use just one submission method. For example, you may choose to upload data as a flat file and then edit any of the uploaded exams via manual data entry.
Updating an Exam Form
Once an Exam form has been submitted to the registry, with all required data elements, its status changes to Completed and it cannot be submitted again manually. However, the Exam form can be edited at any time. For example, a follow-up procedure can be added and saved to the form in the Follow-up Data section. In the event of the patient’s passing, the Date of Death and related information can be added to the Patient Information section and saved. Updating a completed Exam form does not change its status, but it does provide you the ability to add or change information as the need arises.

Enter identifying information in the filter fields and click the Search button.
