About 0R994ZZ
0R994ZZ is the ICD-10-PCS code for a drainage procedure on the thoracic vertebral disc using a percutaneous endoscopic approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to Arthrocentesis, the ICD-9-CM procedure title it maps to (81.91).
For a different body part, codes include 0R904ZZ (occipital-cervical joint), 0R914ZZ (cervical vertebral joint), 0R934ZZ (cervical vertebral disc), 0R944ZZ (cervicothoracic vertebral joint), 0R954ZZ (cervicothoracic vertebral disc), 0R964ZZ (thoracic vertebral joint) and 22 more.
The same procedure with a different approach is coded 0R990ZZ (open) and 0R993ZZ (percutaneous).
With a different device, use 0R9940Z (drainage device).
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.
