Status: Not Valid for Submission
Version:ICD-10-CM 2023
Code Classification:

N13.7 is a non-specific and non-billable ICD-10 code code, consider using a code with a higher level of specificity for a diagnosis of vesicoureteral-reflux. The code is not specific and is NOT valid for the year 2023 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding for Vesicoureteral-reflux

Non-specific codes like N13.7 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for vesicoureteral-reflux:

  • BILLABLE CODE - Use N13.70 for Vesicoureteral-reflux, unspecified
  • BILLABLE CODE - Use N13.71 for Vesicoureteral-reflux without reflux nephropathy
  • NON-BILLABLE CODE - N13.72 for Vesicoureteral-reflux with reflux nephropathy without hydroureter
  • BILLABLE CODE - Use N13.721 for Vesicoureteral-reflux with reflux nephropathy without hydroureter, unilateral
  • BILLABLE CODE - Use N13.722 for Vesicoureteral-reflux with reflux nephropathy without hydroureter, bilateral
  • BILLABLE CODE - Use N13.729 for Vesicoureteral-reflux with reflux nephropathy without hydroureter, unspecified
  • NON-BILLABLE CODE - N13.73 for Vesicoureteral-reflux with reflux nephropathy with hydroureter
  • BILLABLE CODE - Use N13.731 for Vesicoureteral-reflux with reflux nephropathy with hydroureter, unilateral
  • BILLABLE CODE - Use N13.732 for Vesicoureteral-reflux with reflux nephropathy with hydroureter, bilateral
  • BILLABLE CODE - Use N13.739 for Vesicoureteral-reflux with reflux nephropathy with hydroureter, unspecified

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:


Type 1 Excludes

Type 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.

Patient Education


Ureteral Disorders

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.
