About 09JJ4ZZ

09JJ4ZZ is the ICD-10-PCS code for a inspection procedure on the left 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 external ear, the ICD-9-CM procedure title it maps to (18.19).

For a different body part, codes include 09J74ZZ (right tympanic membrane), 09J84ZZ (left tympanic membrane), 09JD4ZZ (right inner ear), 09JE4ZZ (left inner ear), 09JH4ZZ (right ear), 09JK4ZZ (nasal mucosa and soft tissue) and 1 more.

The same procedure with a different approach is coded 09JJ0ZZ (open), 09JJ3ZZ (percutaneous), 09JJ7ZZ (via natural or artificial opening), 09JJ8ZZ (via natural or artificial opening endoscopic) and 09JJXZZ (external).

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.
