About 0RSM45Z
0RSM45Z is the ICD-10-PCS code for a reposition procedure on the left elbow joint using a percutaneous endoscopic approach with external fixation device. In ICD-10-PCS, reposition means moving to its normal location, or other suitable location, all or a portion of a body part.
In plain terms, this corresponds to closed reduction of dislocation of elbow, the ICD-9-CM procedure title it maps to (79.72).
For a different body part, codes include 0RSL45Z (right elbow joint), 0RSN45Z (right wrist joint), 0RSP45Z (left wrist joint), 0RSQ45Z (right carpal joint), 0RSR45Z (left carpal joint), 0RSS45Z (right carpometacarpal joint) and 5 more.
The same procedure with a different approach is coded 0RSM05Z (open), 0RSM35Z (percutaneous) and 0RSMX5Z (external).
With a different device, use 0RSM44Z (internal fixation device) and 0RSM4ZZ (no 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.
