About 09BK8ZX
09BK8ZX is the ICD-10-PCS code for a excision procedure on the nasal mucosa and soft tissue using a via natural or artificial opening endoscopic 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 09B38ZX (right external auditory canal), 09B48ZX (left external auditory canal), 09B58ZX (right middle ear), 09B68ZX (left middle ear), 09B78ZX (right tympanic membrane), 09B88ZX (left tympanic membrane) and 20 more.
The same procedure with a different approach is coded 09BK0ZX (open), 09BK3ZX (percutaneous), 09BK4ZX (percutaneous 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 was added in FY2018, effective October 1, 2017.
