About 099R30Z
099R30Z is the ICD-10-PCS code for a drainage procedure on the left maxillary sinus using a percutaneous 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 099030Z (right external ear), 099130Z (left external ear), 099330Z (right external auditory canal), 099430Z (left external auditory canal), 099730Z (right tympanic membrane), 099830Z (left tympanic membrane) and 16 more.
The same procedure with a different approach is coded 099R00Z (open), 099R40Z (percutaneous endoscopic), 099R70Z (via natural or artificial opening) and 099R80Z (via natural or artificial opening endoscopic).
With a different device, use 099R3ZZ (no device).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
