Several dental providers (oral and maxillofacial surgeons, periodontists, and others) routinely submit claims to medical plans using the 837 Professional Claim. These providers frequently need to designate the tooth number(s) and/or oral cavity area(s) for the reported procedure.
In order to allow a consistent, codified means for specifying tooth and oral cavity information, please add the TOO segment to the 2400 loop of the Professional Claim. Note that the TOO segment can easily report a tooth number or an area of the oral cavity, since the tooth numbering system qualifier is part of the segment.
Note also that the CMS-1500 form has been modified to support the designation of tooth numbers / oral cavity areas for individual procedures.
