ICD-10-PCS 0NN Medical and Surgical: Head and Facial Bones Release

The ICD-10-PCS root operation Release (code series 0NN) refers to freeing a body part from abnormal constraint by cutting or otherwise disrupting the structure that is impeding its normal function. This operation is performed without taking out the body part.

Within the Medical and Surgical section, Release operations for the Head and Facial Bones involve procedures that relieve restrictions related to bones such as the Frontal Bone (codes 0NN10ZZ, open approach; 0NN13ZZ, percutaneous; 0NN14ZZ, percutaneous endoscopic), Parietal Bones, Temporal Bones, and other facial bones including the Nasal, Maxilla, and Mandible. These procedures are carried out via various approaches, demonstrating the flexibility of the classification to document techniques ranging from traditional open surgery to minimally invasive methods. Accurate coding of these head and facial bone release procedures ensures precise clinical documentation of interventions aimed at restoring normal bone mobility and function.

List of ICD-10-PCS codes used to specify 0NN - Release (freeing a body part from an abnormal physical constraint by cutting or by use of force). There are a total of 67 procedure codes in this section.
