Atranstympanic(intratympanic) injection involves placing medication through the tympanic membrane into the middle ear space. CPT69801is used to report this transtympanic injection/tympanocentesis-type service as represented in CPC-style questions. Because the physician performed the injection inboth earsduring the same session, the appropriate bilateral reporting method in this answer set ismodifier -50to indicate abilateral procedure. Reporting69801 × 2is a common trap; many payers require either modifier 50 or RT/LT rather than two units, and the CPC exam typically follows modifier logic as presented in the options. Modifier-22(increased procedural services) would require unusual extra work beyond typical complexity and is not supported by the vignette. Reporting only a single unilateral code (option A) would underreport the bilateral nature. Therefore, the best answer is69801-50, reflecting the same service performed on paired organs during the same encounter.
