ICD-10-PCS Body System: ICD-10-PCS Body System 00 - Central Nervous System and Cranial Nerves

The ICD-10-PCS Central Nervous System and Cranial Nerves section (00) encompasses a variety of root operations, each defining a distinct procedure performed on nervous system structures. These root operations range from removing devices to manipulating anatomy for therapeutic purposes.

For example, Bypass (code 001) involves rerouting the passage of a tubular body part’s contents, while Dilation (007) refers to expanding an orifice or lumen. Procedures like Destruction (005) physically eradicate all or part of a body part using energy or force. Other operations include Excision (00B), the removal of a portion of a body part, and Insertion (00H), which places a non-biological device to assist physiological function without replacing the body part. Additional interventions are Repair (00Q), restoring anatomy and function, and Replacement (00R), inserting material that physically substitutes all or part of a body part. These codes allow precise documentation of complex procedures on the central nervous system and cranial nerves, capturing the clinical intent and approach involved.

List of ICD-10-PCS procedures under ICD-10-PCS Body System 00 - Central Nervous System and Cranial Nerves

• 001 - Bypass - Altering the route of passage of the contents of a tubular body part

• 002 - Change - Taking out or off a device from a body part and putting back an identical or similar device in or on the same body part without cutting or puncturing the skin or a mucous membrane

• 005 - Destruction - Physical eradication of all or a portion of a body part by the direct use of energy, force or a destructive agent

• 007 - Dilation - Expanding an orifice or the lumen of a tubular body part

• 008 - Division - Cutting into a body part without draining fluids and/or gases from the body part in order to separate or transect a body part

• 009 - Drainage - Taking or letting out fluids and/or gases from a body part

• 00B - Excision - Cutting out or off, without replacement, a portion of a body part

• 00C - Extirpation - Taking or cutting out solid matter from a body part

• 00D - Extraction - Pulling or stripping out or off all or a portion of a body part by the use of force

• 00F - Fragmentation - Breaking solid matter in a body part into pieces

• 00H - Insertion - 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

• 00J - Inspection - Visually and/or manually exploring a body part

• 00K - Map - Locating the route of passage of electrical impulses and/or locating functional areas in a body part

• 00N - Release - Freeing a body part from an abnormal physical constraint by cutting or by use of force

• 00P - Removal - Taking out or off a device from a body part

• 00Q - Repair - Restoring, to the extent possible, a body part to its normal anatomic structure and function

• 00R - Replacement - Putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part

• 00S - Reposition - Moving to its normal location or other suitable location all or a portion of a body part

• 00T - Resection - Cutting out or off, without replacement, all of a body part

• 00U - Supplement - Putting in or on biological or synthetic material that physically reinforces and/or augments the function of a body part

• 00W - Revision - Correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device

• 00X - Transfer - Moving, without taking out, all or a portion of a body part to another location to take over the function of all or a portion of a body part
