About 09R877Z

09R877Z is the ICD-10-PCS code for a replacement procedure on the left tympanic membrane using a via natural or artificial opening 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 other operations on middle and inner ear, the ICD-9-CM procedure title it maps to (20.99).

For a different body part, codes include 09R777Z (right tympanic membrane), 09RL77Z (nasal turbinate) and 09RN77Z (nasopharynx).

The same procedure with a different approach is coded 09R807Z (open) and 09R887Z (via natural or artificial opening endoscopic).

With a different device, use 09R87JZ (synthetic substitute) and 09R87KZ (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) and DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), under the surgical category “Other Ear, Nose, Mouth and Throat O.R. Procedures”.

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