Hi Guest! Modifier 50 stands for: Bilateral procedures. I”m not sure you would need to use it to indicate upper & lower, I would just bill for 2 units of the code, and you can indicate in the supplemental information (the red shaded portion of the line item) that it it for both mandibular & maxillary using the “JO” qualifier. Here is some additional information about the JO and JP qualifiers: The following are the codes for tooth numbers, reported with the JP qualifier: • 1 –32: Permanent dentition • 51 –82: Permanent supernumerary dentition • A –T: Primary dentition • AS –TS: Primary supernumerary dentition The following are the codes for areas of the oral cavity, reported with the JO qualifier: • 00 : Entire oral cavity • 01 : Maxillary arch • 02 : Mandibular arch • 10 : Upper right quadrant • 20 : Upper left quadrant • 30 : Lower left quadrant • 40: Lower right quadrant Examples of how this would look on the medical claim can be found in the NUCC”s CMS 1500 claim form manual here, starting on page 46 & 47: Hope this helps!
