UNDERSTANDING RESTRICTION, OCCLUSION, AND DILATION
Editor's note: This article is the sixth in a series of 10 articles discussing the 31 root operations of ICD-IO-PCS.
WITH THE UPCOMING implementation of ICD-IO-PCS, there are new definitions and descriptions used to describe the procedures performed. Coding professionals should start acquainting themselves with the 31 different root operations in the medical and surgical section. An in-depth understanding of the definitions and applications of the various root operations and knowledge of the integral components of procedures will be important in making a smooth transition.
This article focuses on the root operations Restriction, Occlusion, and Dilation. These are three of the four root operations that make up the group defined as procedures that alter the diameter/route of a tubular body part. Their corresponding characters in ICD-IO-PCS are:
* Restriction: Character V
* Occlusion: Character L
* Dilation: Character 7
An article discussing the remaining root operation of this group, Bypass, will appear in the November/December issue of the Journal ofAHIMA.
Root Operation V: Restriction
The ICD-IO-PCS definition for the root operation Restriction is "Partially closing an orifice or the lumen of a tubular body part." For Restriction, the orifice can be a natural orifice or an artificially created orifice. Restriction includes either intraluminal or extraluminal methods for narrowing the diameter (for example, stents or bands).
Examples of Restriction include:
* Esophagogastric fundoplication
* Thoracotomy with banding of left pulmonary artery with extraluminal device
* Restriction of thoracic duct with intraluminal stent
Comparing ICD-9-CM and ICD-10-PCS: Restriction
Transvaginal cervical cerclage
A cervical cerclage procedure is done for an incompetent cervix. The cerclage is used to prevent early changes in a woman's cervix, thus preventing premature labor. During this procedure, a strong suture is inserted at the upper part of the cervix early in the pregnancy, usually between the 12th and 16th week of the pregnancy, and is then removed toward the end of the pregnancy, usually during the 37th week.
In ICD-9-CM, the Alphabetical Index main term entry is Cerclage with the subterm of cervical followed by transvaginal. The code is 67.59, Other repair of internal cervical OS. For code 67.59, there is no specification to show if the procedure was performed via the vagina with endoscopy or without.
