About 0Y6F0ZZ

0Y6F0ZZ is the ICD-10-PCS code for a detachment procedure on the right knee region using an open approach. In ICD-10-PCS, detachment means cutting off all or a portion of the upper or lower extremities.

In plain terms, this corresponds to disarticulation of knee, the ICD-9-CM procedure title it maps to (84.16).
