About 0KN3XZZ

0KN3XZZ is the ICD-10-PCS code for a release procedure on the left neck muscle using an external 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 Stretching of muscle or tendon, the ICD-9-CM procedure title it maps to (93.27).

For a different body part, codes include 0KN0XZZ (head muscle), 0KN1XZZ (facial muscle), 0KN2XZZ (right neck muscle), 0KN4XZZ (tongue, palate, pharynx muscle), 0KN5XZZ (right shoulder muscle), 0KN6XZZ (left shoulder muscle) and 21 more.

The same procedure with a different approach is coded 0KN30ZZ (open), 0KN33ZZ (percutaneous) and 0KN34ZZ (percutaneous endoscopic).

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.
