UB04 - document type

Overview

The UB-04, or CMS-1450, is a standardized claim form used by healthcare providers to bill Medicare, Medicaid, and private insurance for institutional services. It includes essential details about the patient, services provided, and costs incurred, streamlining the reimbursement process for healthcare facilities.

This Document Understanding^TM skill is extracting 26 regular fields and 6 column fields containing key data points of the UB04.

Particularities

The skill is trained to automatically detect data such as:

Billing Name, Billing Address, Billing Tax ID Number;
Patient Name, Patient Address, Patient DoB;
Admission Date, Admission Hour, Type of Visit;
Value Code, Value Amount.

Extracted fields

Note: If you are using using public endpoints, such as https://du.uipath.com/ie/invoices, all fields are available. However, if you are using custom-trained extractors, the availability of extracted fields is dependant on the version you are currently using.

You can also check the list of fields and types on any endpoint in the /info/model object. To access this, simply add /info/model to any endpoint, like so: https://du.uipath.com/ie/invoices/info/model. For an enhanced reading experience of the fields list, it's recommended to install a JSON viewer extension in your browser.
