Wiki should I have not coded LT on stab phlebectomy of the left leg?

[The Angel Of the South]

For my practicode. The pt had varicose veins with pain on the lt leg. The procedure was a stab phlebectomy, but with only 5 incisions; so I coded 37799 per the guidelines.

It didn't say "this payer requires RT/LT modifiers" as is customary, but I coded LT anyway, because that's which leg it was. The rationale is giving me mixed signals about whether that was wrong. Screenshot attached. It scored me the full 3/3, but LT is in red, which normally indicates the code/modifier/units number is incorrect. Is this a practicode error (suggested by giving me full points), or is there some reason a varicose vein phlebectomy should not specify the side?

Hello you can't put modifiers on unlisted procedures but since it was just a laterality vs a specific modifier it wasn't wrong.
per AHA coding clinic unlisted codes of an organ or an anatomic site may use laterality modifiers this is the only exception to mods on unlisted CPT's
