About 09CM8ZZ
09CM8ZZ is the ICD-10-PCS code for a extirpation procedure on the nasal septum using a via natural or artificial opening endoscopic approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.
In plain terms, this corresponds to incision of nose, the ICD-9-CM procedure title it maps to (21.1).
For a different body part, codes include 09C38ZZ (right external auditory canal), 09C48ZZ (left external auditory canal), 09C58ZZ (right middle ear), 09C68ZZ (left middle ear), 09C78ZZ (right tympanic membrane), 09C88ZZ (left tympanic membrane) and 20 more.
The same procedure with a different approach is coded 09CM0ZZ (open), 09CM3ZZ (percutaneous) and 09CM4ZZ (percutaneous endoscopic).
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.
