About 005F0ZZ

005F0ZZ is the ICD-10-PCS code for a destruction procedure on the olfactory nerve 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 destruction of cranial and peripheral nerves, the ICD-9-CM procedure title it maps to (04.2).

For a different body part, codes include 00500ZZ (brain), 00510ZZ (cerebral meninges), 00520ZZ (dura mater), 00560ZZ (cerebral ventricle), 00570ZZ (cerebral hemisphere), 00580ZZ (basal ganglia) and 20 more.

The same procedure with a different approach is coded 005F3ZZ (percutaneous) and 005F4ZZ (percutaneous endoscopic).

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.
