How do I complete the CMS-1500 (08-05) form?
There are no universal instructions for completing the CMS 1500. Each insurance company will provide specific instructions applicable for claims filed to them.

The National Uniform Claim Committee (NUCC) strongly recommends providers contact their health plans or clearinghouses/vendors prior to submitting a claim on the revised form to ensure they are prepared to accept the new form.

Complete instructions can be found on the National Uniform Claim Committee Web site,
