Silver Nitrate 0.2% (2mg/mL) injectable solution; Lot #: 142833@1; Expiration Date:2/8/15" Oregon Subscriber Answer: You should report 51700 (Bladder irrigation, simple, lavage and/or instillation) only once as this code has a medically unlikely edit (MUE) of 1. This edit indicates that you can only bill this code once per encounter/day. The clinical scenario in your example does not indicate that modifier 59 (Distinct procedural service), one of the new X modifiers, or other modifier would be correct in obtaining payment for a second 51700 billing.
