About 09537ZZ

09537ZZ is the ICD-10-PCS code for a destruction procedure on the right external auditory canal using a via natural or artificial opening 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 09547ZZ (left external auditory canal), 09577ZZ (right tympanic membrane), 09587ZZ (left tympanic membrane), 095F7ZZ (right eustachian tube), 095G7ZZ (left eustachian tube), 095L7ZZ (nasal turbinate) and 1 more.

The same procedure with a different approach is coded 09530ZZ (open), 09533ZZ (percutaneous), 09534ZZ (percutaneous endoscopic), 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.
