Hydronephrosis with renal and ureteral calculous obstruction

Version 2020 Billable Code

Valid for Submission

N13.2 is a billable code used to specify a medical diagnosis of hydronephrosis with renal and ureteral calculous obstruction. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code N13.2 might also be used to specify conditions or terms like calculus of kidney and ureter, complete obstruction of the urinary tract, hydronephrosis co-occurrent and due to calculus of kidney and ureter, occlusion of ureter, occlusion of ureter due to calculus, ureteric stone, etc

An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Information for Patients


Kidney Diseases

You have two kidneys, each about the size of your fist. They are near the middle of your back, just below the rib cage. Inside each kidney there are about a million tiny structures called nephrons. They filter your blood. They remove wastes and extra water, which become urine. The urine flows through tubes called ureters. It goes to your bladder, which stores the urine until you go to the bathroom.

Most kidney diseases attack the nephrons. This damage may leave kidneys unable to remove wastes. Causes can include genetic problems, injuries, or medicines. You have a higher risk of kidney disease if you have diabetes, high blood pressure, or a close family member with kidney disease. Chronic kidney disease damages the nephrons slowly over several years. Other kidney problems include

  • Cancer
  • Cysts
  • Stones
  • Infections

Your doctor can do blood and urine tests to check if you have kidney disease. If your kidneys fail, you will need dialysis or a kidney transplant.

Kidney Stones

A kidney stone is a solid piece of material that forms in the kidney from substances in the urine. It may be as small as a grain of sand or as large as a pearl. Most kidney stones pass out of the body without help from a doctor. But sometimes a stone will not go away. It may get stuck in the urinary tract, block the flow of urine and cause great pain.

The following may be signs of kidney stones that need a doctor's help:

  • Extreme pain in your back or side that will not go away
  • Blood in your urine
  • Fever and chills
  • Vomiting
  • Urine that smells bad or looks cloudy
  • A burning feeling when you urinate

Your doctor will diagnose a kidney stone with urine, blood, and imaging tests.

If you have a stone that won't pass on its own, you may need treatment. It can be done with shock waves; with a scope inserted through the tube that carries urine out of the body, called the urethra; or with surgery.

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.
