About 0WHP4YZ
0WHP4YZ is the ICD-10-PCS code for a insertion procedure on the gastrointestinal tract using a percutaneous endoscopic approach with other device. In ICD-10-PCS, insertion means putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part.
In plain terms, this corresponds to other operations of abdominal region, the ICD-9-CM procedure title it maps to (54.99).
For a different body part, codes include 0WH04YZ (head), 0WH14YZ (cranial cavity), 0WH24YZ (face), 0WH34YZ (oral cavity and throat), 0WH44YZ (upper jaw), 0WH54YZ (lower jaw) and 16 more.
The same procedure with a different approach is coded 0WHP0YZ (open), 0WHP3YZ (percutaneous), 0WHP7YZ (via natural or artificial opening) and 0WHP8YZ (via natural or artificial opening endoscopic).
With a different device, use 0WHP41Z (radioactive element) and 0WHP43Z (infusion 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.
