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:
Hi 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.
Thanks,
Michele
