Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 10 more specific codes instead:

  • N13.0 Hydronephrosis with ureteropelvic junction obstruction
  • N13.1 Hydronephrosis with ureteral stricture, not elsewhere classified
  • N13.2 Hydronephrosis with renal and ureteral calculous obstruction
  • N13.3 Other and unspecified hydronephrosis (also a header)
  • N13.4 Hydroureter
  • N13.5 Crossing vessel and stricture of ureter without hydronephrosis
  • N13.6 Pyonephrosis
  • N13.7 Vesicoureteral-reflux (also a header)
  • N13.8 Other obstructive and reflux uropathy
  • N13.9 Obstructive and reflux uropathy, unspecified

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.
