About 099K3ZX

099K3ZX is the ICD-10-PCS code for a drainage procedure on the nasal mucosa and soft tissue using a percutaneous 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 biopsy of nose, the ICD-9-CM procedure title it maps to (21.22).

For a different body part, codes include 09903ZX (right external ear), 09913ZX (left external ear), 09933ZX (right external auditory canal), 09943ZX (left external auditory canal), 09973ZX (right tympanic membrane), 09983ZX (left tympanic membrane) and 16 more.

The same procedure with a different approach is coded 099K0ZX (open), 099K4ZX (percutaneous endoscopic), 099K7ZX (via natural or artificial opening), 099K8ZX (via natural or artificial opening endoscopic) and 099KXZX (external).

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.
