How should corrections be made on the CMS-1500 form?

The preferred method for making corrections on the CMS-1500 form is to use a single line strike-through and write the corrections above the original information. This approach maintains the integrity of the form while clearly reflecting the necessary changes. A strike-through indicates that the original information is no longer accurate, and by writing the corrected information above it, there is a clear and concise way to present the updated data without creating confusion. This method is essential in ensuring that the information flows correctly for processing and review.

Using a black marker, as suggested in another option, can create visibility issues, and may not conform to standard protocols for making professional amendments on official forms. White-out is not an acceptable form of correction because it obscures the original data and can lead to discrepancies in processing. Rewriting the entire form may introduce additional errors and does not reflect previous data accurately, which can also complicate processing. Thus, the strike-through method is the most suitable for clarity and compliance with submission standards.
