Final answer:
Scanned CMS-1500 forms must be filled out using black ink to ensure accurate data capture and processing for medical services billing.
Step-by-step explanation:
Scanned CMS-1500 forms must be filled out using black ink.
The CMS-1500 form is the standard paper claim form used by healthcare providers to bill Medicare and Medicaid as well as private insurers for medical services. It's essential to use black ink when filling out these forms to ensure the information is captured correctly during the scanning process. Different shades or colors of ink might not be recognized by the scanners, leading to errors in data capture and processing of the health insurance claim.
