About the 00H Code Range
The ICD-10-PCS root operation Insertion (code prefix 00H) involves putting in a device into a body part. This operation is classified under the Medical and Surgical section and is specific to the Central Nervous System and Cranial Nerves body system.
Insertion procedures include placing various devices such as radioactive elements, monitoring devices, infusion devices, neurostimulator leads, and other medical implants into locations like the brain, cerebral ventricle, cranial nerves, spinal canal, and spinal cord. These devices may be inserted via different techniques including Open, Percutaneous, and Percutaneous Endoscopic Approaches. For example, code 00H001Z refers to the open approach insertion of a radioactive element into the brain, while 00H33MZ represents the percutaneous insertion of a neurostimulator lead into the brain. The selection of codes depends on both the device type and the approach used, facilitating precise documentation of implant procedures in the nervous system. Accurate use of these codes supports clear communication among healthcare providers and proper billing for insertion procedures.
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, 2025 through September 30, 2026. 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.
