About 0SNKXZZ

0SNKXZZ is the ICD-10-PCS code for a release procedure on the right tarsometatarsal joint 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 manual rupture of joint adhesions, the ICD-9-CM procedure title it maps to (93.26).

For a different body part, codes include 0SN0XZZ (lumbar vertebral joint), 0SN2XZZ (lumbar vertebral disc), 0SN3XZZ (lumbosacral joint), 0SN4XZZ (lumbosacral disc), 0SN5XZZ (sacrococcygeal joint), 0SN6XZZ (coccygeal joint) and 15 more.

The same procedure with a different approach is coded 0SNK0ZZ (open), 0SNK3ZZ (percutaneous) and 0SNK4ZZ (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.
