Bilateral Modifier: Use or Not use?

Bilateral Modifier: Use or Not use?

May 31, 2018

If a patient has a biopsy on the right cheek and one on the left forehead, do we need to put modifiers RT and LT on the codes (11100-RT, 11101-LT)?

No.  The skin is part of the integumentary system, actually the largest organ system in the body.  The concept of laterality does not apply to skin.
