Hydroureteronephrosis ICD-10-CM Codes | 2023

What ICD-10 Codes are Used for Hydroureteronephrosis?

Hydroureteronephrosis is a medical condition characterized by the dilation of the ureter and renal pelvis due to blockage or obstruction. Proper diagnosis and coding of this condition are essential for accurate healthcare management. Here are some commonly used ICD-10 codes for Hydroureteronephrosis, along with their clinical descriptions:

N13.30 - Hydroureteronephrosis, unspecified

This code is used when the exact cause of the hydroureteronephrosis is not specified. It indicates the presence of dilated ureter and renal pelvis without a specific underlying cause.

N13.31 - Hydroureteronephrosis with ureteral stricture

This code is assigned when hydroureteronephrosis is caused by a stricture or narrowing of the ureter, resulting in the dilation of the renal pelvis and ureter.

N13.32 - Hydroureteronephrosis with renal and ureteral calculous obstruction

This code indicates the presence of hydroureteronephrosis caused by an obstruction in the renal pelvis and ureter due to calculi or stones.

N13.39 - Other secondary hydronephrosis and hydroureter

This code is assigned when hydroureteronephrosis is caused by factors other than those mentioned above, such as tumors, trauma, or congenital abnormalities.

N13.70 - Unspecified obstructive and reflux uropathy with hydroureter

This code is used when an unspecified obstructive and reflux uropathy leads to hydroureteronephrosis without further specifying the underlying cause.

N13.71 - Unilateral obstructive uropathy with hydroureter

This code is used when an obstruction in a single kidney causes hydroureteronephrosis.

N13.72 - Bilateral obstructive uropathy with hydroureter

This code is used when both kidneys are affected by obstructive uropathy leading to hydroureteronephrosis.

N13.79 - Other obstructive uropathy with hydroureter

This code is assigned when hydroureteronephrosis is caused by obstructive uropathy due to factors not specified by other codes, such as neoplasms or external compression.

N13.9 - Obstructive and reflux uropathy, unspecified

This code is used when the exact type or cause of obstructive and reflux uropathy leading to hydroureteronephrosis is not specified.

N28.89 - Other specified disorders of kidney and ureter

This code is assigned when there are other specified disorders of the kidney and ureter, resulting in hydroureteronephrosis, not covered by other specific codes.

Which Hydroureteronephrosis ICD codes are Billable? 

N13.30 - Hydroureteronephrosis, unspecified

Yes, this code is billable. It represents the presence of dilated ureter and renal pelvis without specifying the underlying cause, allowing for accurate reimbursement and tracking of cases.

N13.31 - Hydroureteronephrosis with ureteral stricture

Yes, this code is billable. It signifies hydroureteronephrosis caused by a specific condition, ureteral stricture, requiring specific diagnostic and treatment interventions.

N13.32 - Hydroureteronephrosis with renal and ureteral calculous obstruction

Yes, this code is billable. It indicates hydroureteronephrosis resulting from obstruction caused by renal and ureteral calculi, necessitating specialized management and intervention.

N13.39 - Other secondary hydronephrosis and hydroureter

Yes, this code is billable. It covers hydroureteronephrosis resulting from secondary causes not specified by other codes, providing accurate documentation and reimbursement for diverse etiologies.

N13.70 - Unspecified obstructive and reflux uropathy with hydroureter

Yes, this code is billable. It denotes hydroureteronephrosis associated with unspecified obstructive and reflux uropathy, allowing for appropriate reimbursement and tracking of cases with unclear underlying causes.

N13.71 - Unilateral obstructive uropathy with hydroureter

Yes, this code is billable. It signifies hydroureteronephrosis caused by an obstruction in a single kidney, requiring specific diagnostic and management approaches.

N13.72 - Bilateral obstructive uropathy with hydroureter

Yes, this code is billable. It represents hydroureteronephrosis resulting from bilateral obstructive uropathy, necessitating comprehensive evaluation, and intervention for both kidneys.

N13.79 - Other obstructive uropathy with hydroureter

Yes, this code is billable. It covers hydroureteronephrosis caused by obstructive uropathy not specified by other codes, allowing for appropriate documentation and reimbursement for diverse underlying factors.

N13.9 - Obstructive and reflux uropathy, unspecified

Yes, this code is billable. It denotes hydroureteronephrosis associated with unspecified obstructive and reflux uropathy, enabling accurate coding and reimbursement in cases where the specific cause is unclear.

N28.89 - Other specified disorders of kidney and ureter

Yes, this code is billable. It encompasses other specified disorders of the kidney and ureter leading to hydroureteronephrosis, ensuring accurate documentation and reimbursement for specific conditions not covered by other codes.

Clinical Information

• Hydroureteronephrosis is a medical condition characterized by the dilation of the ureter and renal pelvis due to blockage or obstruction, leading to impaired urine flow and potential kidney damage.
• The condition can be caused by various factors, including ureteral strictures, calculous obstruction (renal and ureteral stones), tumors, trauma, congenital abnormalities, obstructive uropathy, and reflux uropathy.
• Symptoms of hydroureteronephrosis may include flank pain, urinary tract infections, blood in the urine, frequent urination, and decreased urine output.
• Diagnosis typically involves a combination of medical history review, physical examination, imaging tests (such as ultrasound, CT scan, or MRI), and urodynamic studies.
• Treatment options depend on the underlying cause and severity of the condition. They may include removing obstructing stones or tumors, ureteral stenting, nephrostomy tube placement, surgical repair of strictures, or addressing the underlying condition causing the obstruction.
• Timely diagnosis and appropriate management are crucial to prevent complications such as kidney damage, urinary tract infections, sepsis, and renal failure.
• Regular follow-up appointments and imaging tests are often necessary to monitor the condition, assess treatment effectiveness, and identify potential recurrence or complications.
• Multidisciplinary collaboration between urologists, nephrologists, radiologists, and other healthcare professionals is essential for a comprehensive evaluation, treatment planning, and ongoing care of patients with hydroureteronephrosis.
