Hi Guest! 41874 – Alveoloplasty, each quadrant (specify) That sounds appropriate for the situation to me – the code”s description asks to specify quadrants, not teeth! Here are the JO qualifiers that you can use to specify the quadrants: 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 46-48: Hope this helps!
