About 10904ZA

10904ZA is the ICD-10-PCS code for a drainage procedure on the products of conception using a percutaneous endoscopic approach (qualifier: fetal cerebrospinal fluid). 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 fetus and amnion, the ICD-9-CM procedure title it maps to (75.35).

The same procedure with a different approach is coded 10900ZA (open), 10903ZA (percutaneous), 10907ZA (via natural or artificial opening) and 10908ZA (via natural or artificial opening endoscopic).

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.
