About 09BK8ZZ

09BK8ZZ 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. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to local excision or destruction of other lesion of nose, the ICD-9-CM procedure title it maps to (21.32).

For a different body part, codes include 09B38ZZ (right external auditory canal), 09B48ZZ (left external auditory canal), 09B58ZZ (right middle ear), 09B68ZZ (left middle ear), 09B78ZZ (right tympanic membrane), 09B88ZZ (left tympanic membrane) and 20 more.

The same procedure with a different approach is coded 09BK0ZZ (open), 09BK3ZZ (percutaneous), 09BK4ZZ (percutaneous endoscopic) and 09BKXZZ (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.
