About 09JK4ZZ

09JK4ZZ is the ICD-10-PCS code for a inspection procedure on the nasal mucosa and soft tissue 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 nose, the ICD-9-CM procedure title it maps to (21.29).

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), 09JJ4ZZ (left ear) and 1 more.

The same procedure with a different approach is coded 09JK0ZZ (open), 09JK3ZZ (percutaneous), 09JK8ZZ (via natural or artificial opening endoscopic) and 09JKXZZ (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.
