About coding ureter compression
The ICD-10-CM code for ureter compression is N13.5 (Crossing vessel and stricture of ureter without hydronephrosis).
Within N13, choose N13.5 (Crossing vessel and stricture of ureter without hydronephrosis) only when documentation doesn't support a more specific option: hydronephrosis with ureteropelvic junction obstruction (N13.0), hydronephrosis with ureteral stricture, not elsewhere classified (N13.1), hydronephrosis with renal and ureteral calculous obstruction (N13.2), other and unspecified hydronephrosis (N13.3), hydroureter (N13.4), Pyonephrosis (N13.6), Vesicoureteral-reflux (N13.7), other obstructive and reflux uropathy (N13.8) and 1 more.
Don't report N13.5 together with the conditions in its Excludes1 note: Crossing vessel and stricture of ureter without hydronephrosis with infection (N13.6).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
Don't confuse with (Excludes1 for N13.5)
- Crossing vessel and stricture of ureter without hydronephrosis with infection (N13.6)
