About the 001 Code Range

The ICD-10-PCS root operation Bypass in the Medical and Surgical section involves creating an alternate pathway to reroute the flow of bodily fluids or contents from one body part to another. This is often done when the usual route is obstructed or impaired.

Within the Central Nervous System and Cranial Nerves body system, bypass procedures typically redirect cerebrospinal fluid from the Cerebral Ventricle or Spinal Canal to various destinations such as the Nasopharynx, Mastoid Sinus, Atrium, or Peritoneal Cavity. The procedure can use different types of substitutes, including Autologous, Synthetic, or Nonautologous Tissue Substitutes, and is performed via several approaches like Open, Percutaneous, or Percutaneous Endoscopic. For example, code 0016070 describes bypass from the cerebral ventricle to the nasopharynx using autologous tissue by an open approach, while 0016376 refers to a similar bypass to the peritoneal cavity done percutaneously. These codes highlight the complexity and precision required for accurate coding of CNS bypass surgeries.

Questions About This Page

How many billable codes are in the 001 range?

Of the 148 codes in this range, 147 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 001 range classify?

The range classifies Bypass procedures, altering the route of passage of the contents of a tubular 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.
