About 07NM3ZZ

07NM3ZZ is the ICD-10-PCS code for a release procedure on the thymus 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 repair of thymus, the ICD-9-CM procedure title it maps to (07.93).

For a different body part, codes include 07N03ZZ (lymphatic, head), 07N13ZZ (lymphatic, right neck), 07N23ZZ (lymphatic, left neck), 07N33ZZ (lymphatic, right upper extremity), 07N43ZZ (lymphatic, left upper extremity), 07N53ZZ (lymphatic, right axillary) and 14 more.

The same procedure with a different approach is coded 07NM0ZZ (open) and 07NM4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC), DRG 165 (Major Chest Procedures without CC/MCC), DRG 628 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 629 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with CC) and DRG 630 (Other Endocrine, Nutritional and Metabolic O.R. Procedures without CC/MCC), under the surgical categories “Major Chest Procedures”, “Other Endocrine, Nutritional and Metabolic O.R. Procedures”, “Other O.R. Procedures of the Blood and Blood Forming Organs” and 4 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
