About 00F5XZZ

00F5XZZ is the ICD-10-PCS code for a fragmentation procedure on the subarachnoid 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), 00F4XZZ (subdural space, intracranial), 00F6XZZ (cerebral ventricle) and 00FUXZZ (spinal canal).

The same procedure with a different approach is coded 00F50ZZ (open), 00F53ZZ (percutaneous) and 00F54ZZ (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.
