Need help to map placement of NEPHROURETEROSTOMY RF

General

We are looking for a LOINC code to map for placement of NEPHROURETEROSTOMY via RF. I do not see any available code for this. But while looking for possible LOINC code it appears that the ‘System’ is the same for NEPHROURETEROSTOMY and nephrostomy. For example,

86390-2 Views^W contrast via nephrostomy tube
System = Abdomen>Kidney & Abdomen+Pelvis>Ureter & Pelvis>Urinary bladder

87188-9 Guidance for percutaneous exchange of nephroureteral stent

System = Abdomen>Kidney & Abdomen+Pelvis>Ureter & Pelvis>Urinary bladder

I believe that there is a difference between NEPHROURETEROSTOMY and nephrostomy?

A nephrostomy drains urine out of the kidney into an external bag, while a nephroureterostomy uses a longer tube that threads through the kidney, down the ureter, and into the bladder.

See link for more information .

My question then is, why is the system for 86390-2 nephrostomy including urinary bladder instead of just kidney?

This sounds like a question for the LOINC team in the event they need to update existing codes and/or create new one(s). Have you asked them?

Yes Thank you Andrea!

Hi Salve, I agree. I did some preliminary check, and we can edit to release 2.83. I will take for editing.

Thank you
