About N13.72

N13.72 is the ICD-10-CM diagnosis code for Vesicoureteral-reflux with reflux nephropathy without hydroureter. It belongs to category N13 (obstructive and reflux uropathy), block N10-N16 (renal tubulo-interstitial diseases) and chapter 14 (diseases of the genitourinary system). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within N13.7, choose N13.72 (with reflux nephropathy without hydroureter) only when documentation doesn't support a more specific option: unspecified (N13.70), without reflux nephropathy (N13.71) and with reflux nephropathy with hydroureter (N13.73).

To report this condition, pick the subcode that matches the documentation: N13.721 (unilateral), N13.722 (bilateral) and N13.729 (unspecified).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
