About 09R207Z

09R207Z is the ICD-10-PCS code for a replacement procedure on the bilateral external ear using an open approach with autologous tissue substitute. In ICD-10-PCS, replacement means putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part.

In plain terms, this corresponds to reconstruction of external auditory canal and construction of auricle of ear, the ICD-9-CM procedure titles it maps to (18.6 and 18.71).

For a different body part, codes include 09R007Z (right external ear), 09R107Z (left external ear), 09R507Z (right middle ear), 09R607Z (left middle ear), 09R707Z (right tympanic membrane), 09R807Z (left tympanic membrane) and 8 more.

The same procedure with a different approach is coded 09R2X7Z (external).

With a different device, use 09R20JZ (synthetic substitute) and 09R20KZ (nonautologous tissue substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
