From what Ive seen the following is the major change:
Block 21 (diagnosis code(s)
The old form has room for 6 diagnosis codes.
The new form has room for 12 diagnosis codes.
The old form has a computer bar in the upper left corner
The new form has a Q scan square in its place.
I cant say with certain that you use ICD-9 codes or ICD-10 codes. ICD-10 becomes effective as of October 1, 2014. Nor can I say what order your enter diagnosis codes on the new form, however, when this information is available, you will be informed. You can download the new form sample at www.nucc.org.
