About 0RG00K0

0RG00K0 is the ICD-10-PCS code for a fusion procedure on the occipital-cervical joint using an open approach with nonautologous tissue substitute (qualifier: anterior approach, anterior column). In ICD-10-PCS, fusion means joining together portions of an articular body part rendering the articular body part immobile.

In plain terms, this corresponds to atlas-axis spinal fusion, the ICD-9-CM procedure title it maps to (81.01).

For a different body part, codes include 0RG10K0 (cervical vertebral joint), 0RG20K0 (cervical vertebral joints, 2 or more), 0RG40K0 (cervicothoracic vertebral joint), 0RG60K0 (thoracic vertebral joint), 0RG70K0 (thoracic vertebral joints, 2 to 7), 0RG80K0 (thoracic vertebral joints, 8 or more) and 1 more.

The same procedure with a different approach is coded 0RG03K0 (percutaneous) and 0RG04K0 (percutaneous endoscopic).

With a different device, use 0RG0070 (autologous tissue substitute), 0RG00A0 (interbody fusion device) and 0RG00J0 (synthetic substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 028 (Spinal Procedures with MCC), DRG 029 (Spinal Procedures with CC or Spinal Neurostimulators), DRG 030 (Spinal Procedures without CC/MCC), DRG 471 (Cervical Spinal Fusion with MCC), DRG 472 (Cervical Spinal Fusion with CC) and DRG 473 (Cervical Spinal Fusion without CC/MCC), under the surgical categories “Spinal Procedures”, “Cervical Spinal Fusion”, “Other O.R. Procedures for Injuries” and 1 more.

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