Wiki 20926 billed with RT/LT modifer Insurance denied can I bill with 50

[leslie.bird@comcast.net]

We billed 20926 on two lines with RT/LT modifiers and the Insurance denied for the use of modifiers. This particular Ins in our state does not like those mod's as well as the XS. Should I bill 20926 on ONE line with the 50 mod OR should I bill TWO lines with the 50 mod on the 2nd line? This is where I'm confused. I found this on a WPS site
Appropriate Usage of 50 mod
"Submit codes with a BILAT SURG on one line appending either modifier 50 using one unit of service (UOS);
AND
Inappropriate Usage
"Do not use modifier 50 for multiple procedures on one organ, such as the skin."
"Do not report a bilateral procedure on two lines of service appending modifier 50 to the second line of service"
Can someone please help me?

Skin doesn't have a RT or LT which is why its denying. I believe it would be 2 units if 2 different wound locations. MUE on the code is 2. If they want 2 lines mod 59 on the second if they don't take the X mods.
