About the 0NH Code Range

The ICD-10-PCS root operation Insertion (code 0NH) in the Medical and Surgical section involves putting in a device into or on the Head and Facial Bones. This procedure is performed to place devices that support, fixate, stimulate, or otherwise assist the targeted bone structures.

Examples of this root operation include inserting various devices such as internal fixation devices, external fixation devices, infusion devices, bone growth stimulators, and neurostimulator generators into bones of the skull and face. These devices may be inserted through different approaches: Open Approach (e.g., insertion of an internal fixation device into the Skull – code 0NH004Z), Percutaneous Approach (e.g., insertion of an infusion device into the skull – code 0NH033Z), or Percutaneous Endoscopic Approach (e.g., insertion of an internal fixation device into the skull – code 0NH044Z). This root operation also applies across specific bones like the Frontal Bone, Temporal Bone, Mandible, and others, demonstrating the detailed coding specificity required for accurate documentation.

Questions About This Page

How many billable codes are in the 0NH range?

Of the 101 codes in this range, 100 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 0NH range classify?

The range classifies Insertion procedures, putting in a non-biological appliance that monitors, assists, performs or prevents a physiological function but does not physically take the place 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.
