About the 0NT Code Range
The ICD-10-PCS root operation Resection (code set starting with 0NT) refers to the surgical removal, in whole or part, of the head and facial bones. This procedure is performed to excise diseased, damaged, or abnormal bone tissue for therapeutic or diagnostic purposes.
Within the Medical and Surgical section, the Resection applies specifically to a variety of bones in the head and face, each accessed via an Open Approach. Examples include resection of the Frontal Bone (code 0NT10ZZ), the Right and Left Parietal Bones (codes 0NT30ZZ and 0NT40ZZ), and multiple facial bones such as the Maxilla (0NTR0ZZ), Mandible (0NTT0ZZ and 0NTV0ZZ), and Zygomatic Bones (0NTM0ZZ and 0NTN0ZZ). This coding framework provides precise identification of the bone involved and confirms surgical access, enabling accurate documentation and billing for head and facial bone resections.
