Peritoneal Dialysis Catheter Lysis
Peritoneal Dialysis Catheter Lysis Clinical History Longstanding indwelling peritoneal dialysis catheter is in place. For the last several weeks, the dialysate solution cannot be completely withdrawn. The patient is referred for diagnostic evaluation of the catheter and peritoneal space and possible intervention for restoration of patency. Technique The procedure, options, and risks were reviewed. After sterile preparation, 49400 contrast was injected into the peritoneal cavity through the peritoneal dialysis catheter under fluoroscopic guidance. Multiple spot images were obtained in multiple obliquities, and the patient 74190 spot images were obtained in multiple obliquities, and the patient was rolled into several...

Article Overview
This premium radiology coding article reviews a peritoneal dialysis catheter case involving diagnostic evaluation of catheter patency and subsequent interventional management. It is aimed at coders and clinicians who need to understand how the encounter is organized for reporting purposes, including the general categories of imaging, intervention, unlisted procedure use, and sedation documentation. The article also discusses why certain portions of the work are reported separately or together and how the case is framed within CPT-based coding guidance.
Why This Topic Matters
Peritoneal dialysis catheter dysfunction can involve multiple distinct service components in a single encounter. Understanding how the diagnostic, interventional, and sedation elements are represented in coding helps support consistent reporting and documentation review.
Article Sections
-
Clinical History
Introduces the patient context and the reason the catheter study and intervention were pursued.
