Are you aware that the D codes are no longer in the HCPC? Does anyone bill Dental for ASC facility? Are you using HCPC D codes? According to BCBS of MN all ASC's should bill on the professional electronic claim format as of 07/01/09. BCBS MN will deny all ASC claims on an institutional format. Now we are getting denials from BCBS for using the invalid HCPC procedure code in professional service. Any input would be nice.
