I/I react d/t nephrostomy catheter, subsequent encounter

This code signifies an infection or inflammatory response occurring as a complication of a previously placed nephrostomy catheter. This reaction is not a mechanical issue but rather a biological response, such as a localized infection or sterile inflammation, affecting the tissue surrounding the catheter.

Use this code when a patient presents for follow-up care or treatment of an infection or inflammatory condition directly attributable to their nephrostomy catheter. This applies to situations where the initial treatment for the complication has already begun, and the patient is returning for subsequent management.

• Requires an additional code to identify the specific infection, if applicable (e.g., B95-B97 for bacterial agents).
• Distinguish from mechanical complications (e.g., displacement, leakage) which have different code assignments.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
