How to Fill the HCFA Form (CMS-1500)

This guide outlines the mapping between the fields in zHealthEHR and the corresponding fields on the HCFA (CMS-1500) Insurance Claim Form. The HCFA form is the standard insurance claim form used by chiropractic practices and other non-hospital healthcare providers to bill both government and commercial insurance payers for services rendered.

This document provides step-by-step instructions on how to accurately enter, update, or modify the relevant information in your zHealth account to ensure the correct data is submitted with each claim. It explains where to input or edit information in zHealth and clarifies the purpose of each field on the HCFA form.
