About 099R80Z

099R80Z is the ICD-10-PCS code for a drainage procedure on the left maxillary sinus using a via natural or artificial opening endoscopic approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to puncture of nasal sinus for aspiration or lavage, the ICD-9-CM procedure title it maps to (22.01).

For a different body part, codes include 099380Z (right external auditory canal), 099480Z (left external auditory canal), 099580Z (right middle ear), 099680Z (left middle ear), 099780Z (right tympanic membrane), 099880Z (left tympanic membrane) and 20 more.

The same procedure with a different approach is coded 099R00Z (open), 099R30Z (percutaneous), 099R40Z (percutaneous endoscopic) and 099R70Z (via natural or artificial opening).

With a different device, use 099R8ZZ (no device).

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.
