When a PTCA is done for in-stent stenosis (T82855A), what is the correct root operation: dilatation or revision?
The correct ICD-10-PCS root operation for a percutaneous transluminal coronary angioplasty (PTCA) performed to treat in-stent restenosis is: Dilatation. PCS Definition: Expanding the orifice or lumen of a tubular body part.
Although the narrowing occurs within a previously placed stent, the intent of the procedure is to restore patency of the vessel lumen, not to alter or correct the stent itself. Revision is assigned only when the goal is to adjust, correct, or reposition an existing device. In cases of in-stent restenosis, the stent remains in place and unchanged. No component of the procedure involves modifying, exchanging, or repairing the device. Therefore, “Dilatation” is the accurate root operation for PTCA performed to treat in-stent stenosis.
