About 09C44ZZ
09C44ZZ is the ICD-10-PCS code for a extirpation procedure on the left external auditory canal using a percutaneous 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 external auditory canal, the ICD-9-CM procedure title it maps to (18.02).
For a different body part, codes include 09C04ZZ (right external ear), 09C14ZZ (left external ear), 09C34ZZ (right external auditory canal), 09C74ZZ (right tympanic membrane), 09C84ZZ (left tympanic membrane), 09CB4ZZ (right mastoid sinus) and 16 more.
The same procedure with a different approach is coded 09C40ZZ (open), 09C43ZZ (percutaneous), 09C47ZZ (via natural or artificial opening), 09C48ZZ (via natural or artificial opening endoscopic) and 09C4XZZ (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.
