N13.5 is a billable ICD-10 code used to specify a medical diagnosis of crossing vessel and stricture of ureter without hydronephrosis. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Acquired stricture of ureter
- Complete obstruction of the urinary tract
- Complete occlusion of ureter by external compression
- Drug-induced retroperitoneal fibrosis
- Extrinsic ureteral obstruction
- Idiopathic retroperitoneal fibrosis
- Kinking of ureter
- Kinking of ureter
- Kinking of ureter without obstruction
- Malignant retroperitoneal fibrosis
- Obstruction of pelviureteric junction
- Obstruction of ureter
- Obstruction of ureteral orifice
- Occlusion of ureter
- Postoperative kinking of ureter
- Postoperative stricture
- Postoperative ureteric constriction
- Retroperitoneal fibrosis
- Stenosis of ureter
- Stricture of ureter
- Stricture of ureter co-occurrent and due to crossing vessel
- Retroperitoneal Fibrosis-. a slowly progressive condition of unknown etiology, characterized by deposition of fibrous tissue in the retroperitoneal space compressing the ureters, great vessels, bile duct, and other structures. when associated with abdominal aortic aneurysm, it may be called chronic periaortitis or inflammatory perianeurysmal fibrosis.
- Idiopathic Retroperitoneal Fibrosis|Ormond's Disease-. a condition characterized by abnormal proliferation of fibrous tissue in the compartment posterior to the peritoneum, for which no underlying cause has been identified.
- Retroperitoneal Fibrosis-. a rare, serious disorder characterized by extensive fibrosis in the retroperitoneum. in most cases its etiology is unknown. in some cases it is related to autoimmunity or metastatic cancer. it leads to the entrapment and obstruction of vital retroperitoneal structures including the ureters.
Tabular List of Diseases and Injuries
The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:
Inclusion TermsInclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Kinking and stricture of ureter without hydronephrosis
Type 1 ExcludesType 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- Crossing vessel and stricture of ureter without hydronephrosis with infection N13.6

Your kidneys make urine by filtering wastes and extra water from your blood. The urine travels from the kidneys to the bladder in two thin tubes called ureters.
The ureters are about 8 to 10 inches long. Muscles in the ureter walls tighten and relax to force urine down and away from the kidneys. Small amounts of urine flow from the ureters into the bladder about every 10 to 15 seconds.
Sometimes the ureters can become blocked or injured. This can block the flow of urine to the bladder. If urine stands still or backs up the ureter, you may get a urinary tract infections.
Doctors diagnose problems with the ureters using different tests. These include urine tests, x-rays, and examination of the ureter with a scope called a cystoscope. Treatment depends on the cause of the problem. It may include medicines and, in severe cases, surgery.
