About 09504ZZ
09504ZZ is the ICD-10-PCS code for a destruction procedure on the right external ear using a percutaneous endoscopic 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 09514ZZ (left external ear), 09534ZZ (right external auditory canal), 09544ZZ (left external auditory canal), 09574ZZ (right tympanic membrane), 09584ZZ (left tympanic membrane), 095B4ZZ (right mastoid sinus) and 16 more.
The same procedure with a different approach is coded 09500ZZ (open), 09503ZZ (percutaneous) and 0950XZZ (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.
