About the 0NS Code Range

The ICD-10-PCS root operation Reposition (code starting with 0NS) involves moving a body part to its normal location or other suitable location. This operation is used specifically within the Medical and Surgical section for the Head and Facial Bones body system.

Reposition typically corrects displacements or fractures of various cranial and facial bones. The extensive code list illustrates different target bones including the Skull, Frontal Bone, Parietal Bones, Temporal Bones, Occipital Bone, Nasal Bone, Sphenoid Bone, Ethmoid Bone, Lacrimal Bones, Palatine Bones, Zygomatic Bones, Orbits, Maxilla, Mandible, and Hyoid Bone. Approaches vary broadly from Open, Percutaneous, and Percutaneous Endoscopic to External. Some procedures involve fixation devices, either Internal or External, to secure the repositioned bone as in 0NS004Z (Reposition Skull with Internal Fixation Device, Open Approach).

These ICD-10-PCS reposition codes enable precise documentation of surgical correction techniques for facial and cranial bone misalignments, reflecting both the anatomical site and method used, which is essential for accurate procedural coding and patient care records.

Questions About This Page

How many billable codes are in the 0NS range?

Of the 174 codes in this range, 173 are billable and valid for inpatient claim submission from October 1, 2025 through September 30, 2026. Table header codes group them but cannot be reported on claims.

What does the 0NS range classify?

The range classifies Reposition procedures, moving to its normal location or other suitable location all or a portion of a body part, performed on the head and facial bones. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
