About 0Q9P40Z

0Q9P40Z is the ICD-10-PCS code for a drainage procedure on the left metatarsal using a percutaneous endoscopic approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to other incision of bone without division, tarsals and metatarsals, the ICD-9-CM procedure title it maps to (77.18).

For a different body part, codes include 0Q9040Z (lumbar vertebra), 0Q9140Z (sacrum), 0Q9240Z (right pelvic bone), 0Q9340Z (left pelvic bone), 0Q9440Z (right acetabulum), 0Q9540Z (left acetabulum) and 18 more.

The same procedure with a different approach is coded 0Q9P00Z (open) and 0Q9P30Z (percutaneous).

With a different device, use 0Q9P4ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 503 (Foot Procedures with MCC), DRG 504 (Foot Procedures with CC) and DRG 505 (Foot Procedures without CC/MCC), under the surgical category “Foot Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
