We are in California. Our billing software has templates for the CMS 1500. That is, the template has all of the boxes and fields on it that the CMS 1500 has. We drag and drop individual "data snatchers" into each field we want printed on the CMS 1500 form. The "data snatchers" correspond to fields in the database. When properly configured, the template pulls all of the correct data from the database for the target patient and the CMS 1500 form is printed properly.
We have used this billing software since the late 1990's. There has never been a "data snatcher" placed into Box 14 on our templates. Since no information has ever been pulled into Box 14 on the template, no information has ever printed on the CMS 1500 form. And we bill for Ob/Gyn as well as Worker's Comp across multiple specialties. Never a peep from anybody about data missing in Box 14.
