Mech compl of nephrostomy catheter, sequela

This code signifies a long-term or late-effect issue arising from a mechanical problem with a nephrostomy catheter. This could include chronic pain, persistent infection, or organ damage that developed as a consequence of a prior catheter malfunction, displacement, or obstruction. The "sequela" aspect indicates that the initial complication has resolved, but its lasting effects are still present and require ongoing management.

Use this code when documenting a patient presenting with a chronic condition directly attributable to a past mechanical complication of a nephrostomy catheter. This is appropriate for follow-up encounters where the initial acute complication has been treated, but the patient continues to experience residual symptoms or conditions. Examples include chronic hydronephrosis due to a previously obstructed catheter, or persistent fistula formation after catheter dislodgement.

• Always sequence this code after the code for the specific sequela (e.g., chronic hydronephrosis).
• Ensure documentation clearly links the current condition to a past mechanical complication of the nephrostomy catheter.
• Do not use for acute or ongoing mechanical complications; those require codes without the "S" seventh character.
