2) S/F
3) SIGNED
4) SOF

Answer 1

The abbreviation 'SOF' is also acceptable when 'SIGNATURE ON FILE' is the correct entry for a CMS-1500 claim block. It indicates the patient's authorization to release medical information for claim processing.

Step-by-step explanation:

When "SIGNATURE ON FILE" is the appropriate entry for a CMS-1500 claim block, the abbreviation SOF is also acceptable as an entry. This abbreviation is widely recognized in the health insurance industry and signifies that the provider has the patient's signature on file, and it is used to indicate that the patient has authorized the release of medical information necessary to process the claim. Alternate entries such as "FILED", "S/F", or "SIGNED" are not standard for this purpose on the CMS-1500 form.
