About 00F4XZZ
00F4XZZ is the ICD-10-PCS code for a fragmentation procedure on the subdural space, intracranial using an external approach. In ICD-10-PCS, fragmentation means breaking solid matter in a body part into pieces.
In plain terms, this corresponds to extracorporeal shockwave lithotripsy of other sites, the ICD-9-CM procedure title it maps to (98.59).
For a different body part, codes include 00F3XZZ (epidural space, intracranial), 00F5XZZ (subarachnoid space, intracranial), 00F6XZZ (cerebral ventricle) and 00FUXZZ (spinal canal).
The same procedure with a different approach is coded 00F40ZZ (open), 00F43ZZ (percutaneous) and 00F44ZZ (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.
