The following slide shows present line-by-line billing instructions for DMAP providers for a variety of claim types.

Where to find billing forms

The DMAP 1036 and DMAP 505 forms are available on the DMAP forms page. You can also order hard copy versions of these forms using the DMAP 2420 (Provider Forms Request).

DMAP does not supply the CMS 1500, ADA or UB claim forms. Sample forms and information about how to order these forms are available in the Supplemental Information document on your provider type's rulebook page. For a link to the rules and guidelines for your provider type, click here.

If you use the Provider Web Portal, you don't need to use paper billing forms. For more information about submitting Web claims, view the Web handbooks listed above or go to the Provider Web Portal information page.
