Question
Hi again! I'm just wondering whether Diagnostic Codes, Line 21 on CMS 1500 are to be exclusively ICD 10 codes or are DSM IV codes also accepted? Thank you, Carol
Answer
Carol,
You can use either ICD or DSM codes in box 21, as long as the codes are recognized by the individual insurance carrier that you are billing.
