About 09510ZZ
09510ZZ is the ICD-10-PCS code for a destruction procedure on the left external ear 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), 09530ZZ (right external auditory canal), 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 09513ZZ (percutaneous), 09514ZZ (percutaneous endoscopic) and 0951XZZ (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.
