About 0HWSX7Z

0HWSX7Z is the ICD-10-PCS code for a revision procedure on the hair using an external approach with autologous tissue substitute. In ICD-10-PCS, revision means correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device.

In plain terms, this corresponds to other miscellaneous procedures, the ICD-9-CM procedure title it maps to (99.99).

For a different body part, codes include 0HWPX7Z (skin), 0HWQX7Z (finger nail) and 0HWRX7Z (toe nail).

With a different device, use 0HWSXJZ (synthetic substitute) and 0HWSXKZ (nonautologous tissue substitute).

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.
