About the 00H Code Range

These procedures place nonbiological devices in the central nervous system or cranial nerves. The devices may monitor, assist, perform, or prevent a body function without replacing a body part.

The fourth character identifies the brain, cerebral ventricle, cranial nerve, spinal canal, or spinal cord. The fifth distinguishes open exposure from entry through a puncture or small incision, with or without endoscopic viewing. The sixth names the device, including radioactive elements, monitoring or infusion devices, and neurostimulator leads. The seventh specifies Temporary or No Qualifier.

Questions About This Page

How many billable codes are in the 00H range?

Of the 79 codes in this range, 78 are billable and valid for inpatient claim submission from October 1, 2026 through September 30, 2027. Table header codes group them but cannot be reported on claims.

What does the 00H 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 central nervous system and cranial nerves. Each code adds the body part, approach, device, and qualifier in characters four through seven, and links to its own reference page.
