About 099V8ZX

099V8ZX is the ICD-10-PCS code for a drainage procedure on the left ethmoid sinus using a via natural or artificial opening endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to closed [endoscopic] [needle] biopsy of nasal sinus, the ICD-9-CM procedure title it maps to (22.11).

For a different body part, codes include 09938ZX (right external auditory canal), 09948ZX (left external auditory canal), 09958ZX (right middle ear), 09968ZX (left middle ear), 09978ZX (right tympanic membrane), 09988ZX (left tympanic membrane) and 20 more.

The same procedure with a different approach is coded 099V0ZX (open), 099V3ZX (percutaneous), 099V4ZX (percutaneous endoscopic) and 099V7ZX (via natural or artificial opening).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2018, effective October 1, 2017.
