Breakdown (mechanical) of nephrostomy catheter, subs

This code signifies a mechanical failure or malfunction of a nephrostomy catheter that has been previously placed. This breakdown could involve issues such as kinking, fracturing, or dislodgement of the catheter itself, impairing its ability to drain urine from the kidney effectively.

Apply this code when a patient presents for follow-up care or an unscheduled visit due to a mechanical problem with an existing nephrostomy catheter. This includes situations where the catheter needs repair, replacement, or repositioning because of a structural defect or failure. The "D" seventh character indicates that this is a subsequent encounter for care after the initial treatment of the breakdown.

• Ensure documentation clearly specifies a mechanical breakdown of the catheter, not an infection or other complication.
• Confirm the encounter is for follow-up care related to the catheter malfunction, not the initial placement or an unrelated issue.
• Verify the "D" seventh character is appropriate for a subsequent encounter for the management of the breakdown.
