Hi! To ensure accuracy, the office needs to bill out for exactly what was done on the DOS- for example, if a D0330 was completed, a D0330 needs to be billed out. If D0220 and 3 D0230s were completed, those are the codes that should be billed out. Some insurances will only pay the max allowed amount of a D0210 if D0330 and bwx or PA's are billed in conjunction (ex: max allowable for D0210 is $75, provider bills D0330 and D0274, the max insurance will pay is $75 total for both, however they divide up that payment). Please let us know if further clarification is required.
