About 0T577ZZ

0T577ZZ is the ICD-10-PCS code for a destruction procedure on the left ureter using a via natural or artificial opening approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.

The same procedure with a different approach is coded 0T570ZZ (open), 0T573ZZ (percutaneous), 0T574ZZ (percutaneous endoscopic) and 0T578ZZ (via natural or artificial opening endoscopic).
