In CPT coding, what does the -50 modifier indicate when attached to a procedure code?

Explanation:
The -50 modifier shows that the procedure was performed on both sides of the body in the same surgical session. It signals a bilateral service, so the payer recognizes that two equivalent procedures occurred (left and right) and may reimburse accordingly. You add this modifier to the CPT code describing the procedure when the surgeon treated paired anatomy on both sides in one encounter. Some codes are already defined as bilateral and don’t require -50, and using it on those would be inappropriate. The other options don’t describe bilateral status: it isn’t about a hospital facility charge, it isn’t about an unrelated procedure, and the professional component is indicated by a different modifier (26).
