About 09548ZZ
09548ZZ is the ICD-10-PCS code for a destruction procedure on the left external auditory canal using a via natural or artificial opening 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 09538ZZ (right external auditory canal), 09558ZZ (right middle ear), 09568ZZ (left middle ear), 09578ZZ (right tympanic membrane), 09588ZZ (left tympanic membrane), 09598ZZ (right auditory ossicle) and 20 more.
The same procedure with a different approach is coded 09540ZZ (open), 09543ZZ (percutaneous), 09544ZZ (percutaneous endoscopic), 09547ZZ (via natural or artificial opening) and 0954XZZ (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.
