About 09NK3ZZ

09NK3ZZ is the ICD-10-PCS code for a release procedure on the nasal mucosa and soft tissue using a percutaneous approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to lysis of adhesions of nose, the ICD-9-CM procedure title it maps to (21.91).

For a different body part, codes include 09N03ZZ (right external ear), 09N13ZZ (left external ear), 09N33ZZ (right external auditory canal), 09N43ZZ (left external auditory canal), 09N73ZZ (right tympanic membrane), 09N83ZZ (left tympanic membrane) and 16 more.

The same procedure with a different approach is coded 09NK0ZZ (open), 09NK4ZZ (percutaneous endoscopic), 09NK8ZZ (via natural or artificial opening endoscopic) and 09NKXZZ (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.
