About 0R900ZX
0R900ZX is the ICD-10-PCS code for a drainage procedure on the occipital-cervical joint using an open approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.
In plain terms, this corresponds to biopsy of joint structure, other specified sites, the ICD-9-CM procedure title it maps to (80.39).
For a different body part, codes include 0R910ZX (cervical vertebral joint), 0R930ZX (cervical vertebral disc), 0R940ZX (cervicothoracic vertebral joint), 0R950ZX (cervicothoracic vertebral disc), 0R960ZX (thoracic vertebral joint), 0R990ZX (thoracic vertebral disc) and 22 more.
The same procedure with a different approach is coded 0R903ZX (percutaneous) and 0R904ZX (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.
