About 09PH77Z

09PH77Z is the ICD-10-PCS code for a removal procedure on the right ear using a via natural or artificial opening approach with autologous tissue substitute. In ICD-10-PCS, removal means taking out or off a device from 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 09PJ77Z (left ear) and 09PK77Z (nasal mucosa and soft tissue).

The same procedure with a different approach is coded 09PH07Z (open), 09PH37Z (percutaneous), 09PH47Z (percutaneous endoscopic), 09PH87Z (via natural or artificial opening endoscopic) and 09PHX7Z (external).

With a different device, use 09PH70Z (drainage device), 09PH7DZ (intraluminal device), 09PH7JZ (synthetic substitute), 09PH7KZ (nonautologous tissue substitute) and 09PH7YZ (other device).

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.
