About 09530ZZ
09530ZZ is the ICD-10-PCS code for a destruction procedure on the right external auditory canal using an open approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.
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 09500ZZ (right external ear), 09510ZZ (left external ear), 09540ZZ (left external auditory canal), 09550ZZ (right middle ear), 09560ZZ (left middle ear), 09570ZZ (right tympanic membrane) and 22 more.
The same procedure with a different approach is coded 09533ZZ (percutaneous), 09534ZZ (percutaneous endoscopic), 09537ZZ (via natural or artificial opening), 09538ZZ (via natural or artificial opening endoscopic) and 0953XZZ (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.
