Procedure Overview
Dilation procedures widen the cervix or another opening within the female reproductive tract to allow instruments to pass, fluid to drain, or the natural anatomy to function normally again. Cervical dilation is the most familiar example, performed to open the cervical canal before a dilation and curettage, before placement of an intrauterine device, or to relieve cervical stenosis that is causing painful or obstructed menstrual flow.
The procedure can be done mechanically, using graduated dilator rods of increasing size, or with medication such as misoprostol or a laminaria stick that gradually softens and opens the cervix over several hours. Dilation is often a preparatory step that enables a subsequent procedure rather than a treatment on its own, though in cases of cervical stenosis or scarring it can directly relieve a patient's symptoms by restoring normal passage.
Anatomy & Axis Detail
Fallopian Tube, Right
The right fallopian tube carries the oocyte from the right ovary toward the uterus, and dilation of this structure is performed to widen a segment narrowed or occluded by scarring, mucus plugging, or proximal tubal obstruction, most often in the setting of infertility evaluation and treatment. The procedure is typically accomplished through selective catheterization under fluoroscopic or hysteroscopic guidance, threading a catheter or guidewire through the tubal ostium to mechanically open the lumen without cutting or removing tissue. Because the tube is delicate and prone to perforation, the dilating force is applied incrementally and imaging is used to confirm restored patency, often with a contrast study performed in the same session. Laterality is essential to specify, since the right and left tubes are treated as distinct anatomic sites in coding.
Approach: Open
Open approach means the surgeon cuts through skin, mucous membrane, or other tissue layers to physically expose the target site to view before performing the procedure. It gives direct visualization and hands-on access, distinguishing it from Percutaneous approaches where instruments pass through a small puncture without exposing the site. Open is typical for procedures needing wide access, such as most laparotomies.
Device: Intraluminal Device
Intraluminal Device denotes a single device, such as a stent or occlusion device, positioned within the lumen of a tubular body part like a vessel, duct, or airway to maintain patency or occlude flow. It carries no drug coating or radioactivity, distinguishing it from the drug-eluting, radioactive, and bioactive intraluminal device values, and from Extraluminal Device, which sits outside rather than inside the lumen.
Coding & Documentation
The operative or procedure note should explicitly describe widening of the cervical canal or another tubular opening, typically stating the size or degree of dilation achieved and the method used. When dilation is performed solely to gain access for another procedure, such as curettage or hysteroscopy, coding guidelines generally consider it a component of that other procedure rather than a separately reportable code, and coders should check whether the two are bundled under the same operative episode. A frequent error is coding Dilation as a standalone procedure when it was clearly incidental to a more definitive intervention performed immediately afterward in the same session.
