About 07N64ZZ

07N64ZZ is the ICD-10-PCS code for a release procedure on the lymphatic, left axillary using a percutaneous endoscopic 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 other operations on lymphatic structures, the ICD-9-CM procedure title it maps to (40.9).

For a different body part, codes include 07N04ZZ (lymphatic, head), 07N14ZZ (lymphatic, right neck), 07N24ZZ (lymphatic, left neck), 07N34ZZ (lymphatic, right upper extremity), 07N44ZZ (lymphatic, left upper extremity), 07N54ZZ (lymphatic, right axillary) and 14 more.

The same procedure with a different approach is coded 07N60ZZ (open) and 07N63ZZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 802 (Other O.R. Procedures of the Blood and Blood Forming Organs with MCC), DRG 803 (Other O.R. Procedures of the Blood and Blood Forming Organs with CC), DRG 804 (Other O.R. Procedures of the Blood and Blood Forming Organs without CC/MCC), DRG 820 (Lymphoma and Leukemia with Major O.R. Procedures with MCC), DRG 821 (Lymphoma and Leukemia with Major O.R. Procedures with CC) and DRG 822 (Lymphoma and Leukemia with Major O.R. Procedures without CC/MCC), under the surgical categories “Other O.R. Procedures of the Blood and Blood Forming Organs”, “Lymphoma and Leukemia with Major O.R. Procedures”, “Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures” and 1 more.

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