- •Document the specific type of catheter (arteriovenous fistula, graft, or temporary catheter) in the medical record
Clinical Significance
This code indicates a patient requires ongoing dialysis for end-stage renal disease with encounters for hemodialysis catheter management, representing severe kidney dysfunction requiring life-sustaining treatment. Extracorporeal dialysis catheter care is essential for maintaining vascular access for hemodialysis.
Documentation Requirements
- ✓Documentation of encounter for catheter fitting, adjustment, or maintenance
- ✓Specification of extracorporeal dialysis catheter type
- ✓Patient's underlying end-stage renal disease status
- ✓Type of catheter service provided (insertion, adjustment, replacement)
- ✓Dialysis access site and catheter functionality
- ✓Provider performing catheter management
- ✓Any complications with catheter or access site
- ✓Ongoing dialysis treatment plan
