About 0JN4XZZ

0JN4XZZ is the ICD-10-PCS code for a release procedure on the subcutaneous tissue and fascia, right neck 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 fascia, the ICD-9-CM procedure title it maps to (93.28).

For a different body part, codes include 0JN0XZZ (subcutaneous tissue and fascia, scalp), 0JN1XZZ (subcutaneous tissue and fascia, face), 0JN5XZZ (subcutaneous tissue and fascia, left neck), 0JN6XZZ (subcutaneous tissue and fascia, chest), 0JN7XZZ (subcutaneous tissue and fascia, back), 0JN8XZZ (subcutaneous tissue and fascia, abdomen) and 15 more.

The same procedure with a different approach is coded 0JN40ZZ (open) and 0JN43ZZ (percutaneous).

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.
