What code should be reported for a bilateral sinus endoscopy with partial resection of the ethmoid?

The appropriate code for a bilateral sinus endoscopy with partial resection of the ethmoid is indeed 31254-50. This code specifically refers to a bilateral procedure, indicated by the "-50" modifier, which signifies that the procedure was performed on both sides.

In this context, 31254 includes both the endoscopic technique used to access the sinus and the partial resection of the ethmoid, which is a crucial aspect of the procedure. The inclusion of the "-50" modifier assures proper recognition of the bilateral nature of the surgery when billing, ensuring that the procedure is appropriately reimbursed for both sides.

Other codes listed may pertain to different types of sinus procedures but do not capture the bilateral aspect in conjunction with the specific work done on the ethmoid sinus. For example, options like 31276 might refer to a different procedure entirely, which separates it from the context of a bilateral endoscopy involving ethmoid resection. The specificity of 31254-50 for the bilateral nature and the specific resection makes it the correct choice.
