About 0H99X0Z

0H99X0Z is the ICD-10-PCS code for a drainage procedure on the skin, perineum using an external approach with drainage device. 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 incision of vulva and perineum, the ICD-9-CM procedure title it maps to (71.09).

For a different body part, codes include 0H90X0Z (skin, scalp), 0H91X0Z (skin, face), 0H92X0Z (skin, right ear), 0H93X0Z (skin, left ear), 0H94X0Z (skin, neck), 0H95X0Z (skin, chest) and 20 more.

With a different device, use 0H99XZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC), DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), DRG 746 (Vagina, Cervix and Vulva Procedures with CC/MCC) and DRG 747 (Vagina, Cervix and Vulva Procedures without CC/MCC), under the surgical categories “Other Skin, Subcutaneous Tissue and Breast Procedures” and “Vagina, Cervix and Vulva Procedures”.
