About 09BKXZX

09BKXZX is the ICD-10-PCS code for a excision procedure on the nasal mucosa and soft tissue using an external 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 09B0XZX (right external ear), 09B1XZX (left external ear), 09B3XZX (right external auditory canal) and 09B4XZX (left external auditory canal).

The same procedure with a different approach is coded 09BK0ZX (open), 09BK3ZX (percutaneous), 09BK4ZX (percutaneous endoscopic) and 09BK8ZX (via natural or artificial opening endoscopic).

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.
