The electronic form used in modern healthcare billing is based on the HCFA 1500 paper form, also known as the CMS-1500 form. The Claim.MD online version of this form retains the familiarity of the standard paper form but allows for additional electronic elements supported in the 837P electronic claim standard. This document gives a description of each field on the claim form and a crosswalk to their associated electronic elements.
The paper version of the claim form (HCFA 1500) can be visually compared to identify the differences. For instance, on the paper claim form, the patient/authorized person's signature is placed in Block 12, while the insured/authorized signature is in Block 13. However, these blocks are not present in the electronic Claim.MD version.
This crosswalk serves as a reference, and much of the data used in the X12 ANSI format is derived from the content presented on the website.
