Wiki Billing mod -50 in an ASC

Would anyone know how a claim from an ASC should be billed for a procedure code like 69436, where in CPT it states to use -50 to report bilateral procedures? In SE1422 there is a caution note that states:
Providers and suppliers, other than ambulatory surgical centers (ASCs), are reminded that Medicare billing instructions require claims for certain bilateral surgical procedures to be filed using a -50 modifier and one unit of service (UOS).
But if billed as two line items or with a unit of 2 then it hits a MUE edit, with a MAI 2.

ASC billing is not something I am familiar with so any help would be appreciated.

TIA
