About 09JD4ZZ

09JD4ZZ is the ICD-10-PCS code for a inspection procedure on the right inner ear using a percutaneous endoscopic approach. In ICD-10-PCS, inspection means visually and/or manually exploring a body part.

In plain terms, this corresponds to other diagnostic procedures on middle and inner ear, the ICD-9-CM procedure title it maps to (20.39).

For a different body part, codes include 09J74ZZ (right tympanic membrane), 09J84ZZ (left tympanic membrane), 09JE4ZZ (left inner ear), 09JH4ZZ (right ear), 09JJ4ZZ (left ear), 09JK4ZZ (nasal mucosa and soft tissue) and 1 more.

The same procedure with a different approach is coded 09JD0ZZ (open), 09JD3ZZ (percutaneous), 09JD8ZZ (via natural or artificial opening endoscopic) and 09JDXZZ (external).

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.
