About 0J990ZX

0J990ZX is the ICD-10-PCS code for a drainage procedure on the subcutaneous tissue and fascia, buttock 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 other diagnostic procedures on skin and subcutaneous tissue, the ICD-9-CM procedure title it maps to (86.19).

For a different body part, codes include 0J900ZX (subcutaneous tissue and fascia, scalp), 0J910ZX (subcutaneous tissue and fascia, face), 0J940ZX (subcutaneous tissue and fascia, right neck), 0J950ZX (subcutaneous tissue and fascia, left neck), 0J960ZX (subcutaneous tissue and fascia, chest), 0J970ZX (subcutaneous tissue and fascia, back) and 15 more.

The same procedure with a different approach is coded 0J993ZX (percutaneous).

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.
