About 09BK0ZX

09BK0ZX is the ICD-10-PCS code for a excision procedure on the nasal mucosa and soft tissue using an open approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of 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 09B00ZX (right external ear), 09B10ZX (left external ear), 09B30ZX (right external auditory canal), 09B40ZX (left external auditory canal), 09B50ZX (right middle ear), 09B60ZX (left middle ear) and 22 more.

The same procedure with a different approach is coded 09BK3ZX (percutaneous), 09BK4ZX (percutaneous endoscopic), 09BK8ZX (via natural or artificial opening endoscopic) and 09BKXZX (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.
