About the 05N Code Range

The ICD-10-PCS root operation Release (code 05N) refers to freeing a body part, typically veins in this context, from abnormal constriction or adhesions to restore normal function or mobility.

This operation is classified under the Medical and Surgical section and targets the Upper Veins. Specific examples include the Release of the Azygos Vein via various approaches such as Open (05N00ZZ), Percutaneous (05N03ZZ), and Percutaneous Endoscopic (05N04ZZ) methods. Other veins addressed with release procedures include the Hemiazygos Vein, Innominate Veins (right and left), Subclavian Veins, Axillary Veins, Brachial Veins, and even smaller veins like the Cephalic, Basilic, and Facial Veins. This operation’s versatility in approach allows precise documentation of methods used to free veins from obstructions in different regions, essential for accurate medical coding and clinical communication.
