Ask AIBill This Code — Sign Up Free

E843 is an add-on fee payable when an endoscopic sphenoidotomy (Z350) is performed bilaterally. This fee is added to the fee for the primary unilateral procedure to account for the work on the second side.

When to Use

  • Use E843 as an add-on when you perform a bilateral endoscopic sphenoidotomy, billing Z350 for the first side and E843 for the second side.
  • Apply E843 specifically when the surgical scope is introduced into both the left and right sphenoid sinuses during the same operative session.

Common Pitfalls

  • Billing E843 without an accompanying Z350 claim will result in an automatic rejection as it is a dependent add-on code.
  • Attempting to bill E843 for a unilateral procedure is a common audit trigger; ensure the operative report explicitly confirms bilateral involvement.

Billing Tips

  • You may stack E845 (image guidance) alongside both Z350 and E843 if the clinical criteria for image guidance are met for the bilateral procedure.
