- The root operation “restriction” is used when the surgeon partially closes (partial occlusion) an orifice or the lumen of a tubular body part. The tubular body parts are defined in ICD-10-PCS as those hollow body parts that provide a route of passage for solids, liquids, or gases. The objective of these procedures is to narrow the diameter and includes both intraluminal and extraluminal methods for narrowing the diameter. Restriction can be performed in a natural or artificially created orifice.
Examples of Restriction:
- Gastroesophageal fundoplication
- Cervical cerclage
- Banding of pulmonary artery using extraluminal device
- Clipping of cerebral aneurysm (do not want to completely close off)
- Placement of restrictive stent in right lacrimal duct
- Laparoscopic banding for obesity
- Endovascular AAA repair with/without device
- The root operation “occlusion” is used when the surgeon completely closes an orifice or the lumen of a tubular body part. The objective of these procedures is to close off a tubular body part or orifice and includes both intraluminal and extraluminal methods for occlusion/closure. Occlusion may be performed on a natural or artificially created orifice. This differs from Restriction in that it completely closes and not partially.
Examples of Occlusion:
- Bilateral tubal ligation with Hulka clips
- Ligation of esophageal vein
- Embolization of internal carotid-cavernous fistula
- Embolization of vascular supply to intracranial meningioma
- Embolization of uterine artery
- Banding of esophageal varices
- Banding of hemorrhoids
Take Away: The difference in restriction and occlusion is that restriction partially closes the orifice or lumen of a tubular body part and occlusion completely closes the orifice or lumen of a tubular body part.
