A physician performs corticosteroid injections into both knees at the same session. Depending on payer preference, how is bilaterality typically indicated?
Select an answer to reveal the explanation.
Short Explanation
Two knees, one session: bilaterality is the story. Modifier 50 or paired RT/LT—whichever the payer wants—beats guessing with 22 or 51 alone.
Full Explanation
Bilateral procedures at the same session are commonly reported with modifier 50 or with RT and LT on separate lines per payer policy. Modifier 22 addresses increased services, not bilaterality by itself. Modifiers 78 and 51 do not replace proper bilateral or laterality reporting for paired joint injections.
