Dilation-Root Operation 7
Dilation is defined as expanding an orifice or the lumen of a tubular body part. The orifice can be natural or artificially created. The dilation procedure is accomplished by stretching a tubular body part using intraluminal pressure or by cutting part of the orifice or wall of the tubular body part.
The objective of the dilation procedure is to enlarge the diameter of a tubular body part or orifice. It includes both intraluminal and extraluminal methods for enlarging the diameter. A device placed to maintain the new diameter is an integral part of the dilation procedure and is coded to a sixth-character device value.
Examples of dilation procedures include percutaneous transluminal angioplasty, dilation of the common bile duct, and percutaneous transluminal coronary angioplasty.
