About 2W3AX2Z

2W3AX2Z is the ICD-10-PCS code for a immobilization procedure on the right upper arm using an external approach with cast. In ICD-10-PCS, immobilization means limiting or preventing motion of a body region.

In plain terms, this corresponds to application of other cast, the ICD-9-CM procedure title it maps to (93.53).

For a different body part, codes include 2W30X2Z (head), 2W31X2Z (face), 2W32X2Z (neck), 2W33X2Z (abdominal wall), 2W34X2Z (chest wall), 2W35X2Z (back) and 23 more.

With a different device, use 2W3AX1Z (splint), 2W3AX3Z (brace) and 2W3AXYZ (other 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.
