About 09B48ZZ
09B48ZZ is the ICD-10-PCS code for a excision procedure on the left external auditory canal 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 excision or destruction of other lesion of external ear, the ICD-9-CM procedure title it maps to (18.29).
For a different body part, codes include 09B38ZZ (right external auditory canal), 09B58ZZ (right middle ear), 09B68ZZ (left middle ear), 09B78ZZ (right tympanic membrane), 09B88ZZ (left tympanic membrane), 09B98ZZ (right auditory ossicle) and 20 more.
The same procedure with a different approach is coded 09B40ZZ (open), 09B43ZZ (percutaneous), 09B44ZZ (percutaneous endoscopic), 09B47ZZ (via natural or artificial opening) and 09B4XZZ (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.
