About the 0CT Code Range

The ICD-10-PCS root operation Resection (code 0CT) refers to the complete removal of a body part. Within the Medical and Surgical section, this operation is applied to parts of the Mouth and Throat body system.

This Resection operation involves surgically taking out an entire anatomical structure to treat or manage disease. The codes specify various target body parts and approaches, including removal of the Upper Lip (e.g., 0CT00ZZ for open approach, 0CT0XZZ for external approach), the Pharynx via open, percutaneous endoscopic, or natural/artificial openings (e.g., 0CTM0ZZ, 0CTM4ZZ, 0CTM7ZZ), and the Larynx with similar multiple approaches (0CTS0ZZ, 0CTS4ZZ, 0CTS7ZZ). Other examples include resection of salivary glands, Tongue, Tonsils, and Vocal Cords. The approach used—open, external, or endoscopic—allows precise documentation of the surgical technique. These detailed codes support accurate recording of mouth and throat resections in procedural claims and medical records.
